Answers
Answer:
The inequality is false and equals -14=3
Step-by-step explanation:
You want to start by cancelling equal terms on both sides of the equation which means getting rid of both 8's. You are left with (-7)-(7)=7+(-4).
From here you want to solve both sides meaning adding -7-7 because both terms are negative they will combine, and the other side which is -7+4. They are opposite terms so you will subtract. This leaves you with -14=3 which is false.
Richard wants to purchase a new Havaianas. The cost of the havaianas he wants to buy is Php299. Richard has saved Php42 for his new purchase. His parents are willing you give him three times what he has saved. On the weekends. Richard cut lawns for Php20 an hour. How many more hours will Richard have to work until he has enough money to purchase his Havaianas?
Answers
Using the required arithmetic operations, the number of mowing hours required to meet up with the cost of the Havannian ls 7 hours.
Cost of Havannian = Php 299Amount saved = Php 42The amount he'll be given by his parents = 3(42) = Php 126
Total amount = 42 + 126 = Php 168
Amount left to meet up cost of Havannian = (299 - 168) = Php 131
Lawn cutting rate per hour = Php 20
Number of cutting hours needed = (Php 131 ÷ Php 20) = 6.55 hours
Therefore, in other to meet up with the cost of the Havannian, hell have to mow for atleast 7 hours.

The hours Richard would have to work more in order to purchase his Havaians is 7 hours.
The first step to take in order to determine the answer is to determine the total amount Richard has.
Amount saved = Php 42
Amount his parents would give him = php 42 x 3 = php 126
Total amount Richard has = 126 + 42 = Php 168
The total amount Richard has to get in order to purchase the item:
Php 299 - Php 168 = Php 131
The total hours Richard has to work in order to have enough money = Php 131 / 20 = 6.55 hours
This is approximately 7 hours.

Keith plays basketball at a gym. He can get a $20 membership card and pay $2 for every visit, or he can go any time and just pay $5 for each visit. Which two equations represent the two options for his
number of visits with his total ccost?
Answers
The two equations that can be used to represent his number of visits with his total cost will be 20 + 2x and 5x.
Let the number of visits be represented by x.
Since Keith can get a $20 membership card and pay $2 for every visit, or he can go any time and just pay $5 for each visit, then the equation to represent the information will be:
20 + (2 × x) = (5 × x)
20 + 2x = 5x
Therefore, the equations will be 20 + 2x and 5x.

Q1) Gary has 40 oranges. Gary gives Maya 1/4 of his oranges. Gary also loses 2/5 of the rest of them. How many does Gary have left?
Answers
Answer: 3
Step-by-step explanation:
40/4 = 10
So, if he gave away 1/4 of his oranges he now has 30 oranges left
Next, to find 2/5 of 30, divide 30 by 5 and multiply by 2
30/5=6
6•2=12
So, he lost 12 oranges which leaves him with 18.
40-10=30
30-12=18
Gary has 18 oranges left

25² x 4² square root
Answers
Answer:
25.317977802344
Step-by-step explanation:
25x25= 625
4x4= 16
625+16= 641
The square root of 641 is 25.317977802344
n this case we are going to use the 'Babylonian Method' to get the square root of any positive number.
We must set an error for the final result. Say, smaller than 0.01. In other words, we will try to find the square root value with at least 1 correct decimal place.
Step 1:
Divide the number (641) by 2 to get the first guess for the square root.
First guess = 641/2 = 320.5.
Step 2:
Divide 641 by the previous result. d = 641/320.5 = 2.
Average this value (d) with that of step 1: (2 + 320.5)/2 = 161.25 (new guess).
Error = new guess - previous value = 320.5 - 161.25 = 159.25.
159.25 > 0.01. As error > accuracy, we repeat this step again.
Step 3:
Divide 641 by the previous result. d = 641/161.25 = 3.9751937984.
Average this value (d) with that of step 2: (3.9751937984 + 161.25)/2 = 82.6125968992 (new guess).
Error = new guess - previous value = 161.25 - 82.6125968992 = 78.6374031008.
78.6374031008 > 0.01. As error > accuracy, we repeat this step again.
Step 4:
Divide 641 by the previous result. d = 641/82.6125968992 = 7.7591072555.
Average this value (d) with that of step 3: (7.7591072555 + 82.6125968992)/2 = 45.1858520774 (new guess).
Error = new guess - previous value = 82.6125968992 - 45.1858520774 = 37.4267448218.
37.4267448218 > 0.01. As error > accuracy, we repeat this step again.
Step 5:
Divide 641 by the previous result. d = 641/45.1858520774 = 14.1858562034.
Average this value (d) with that of step 4: (14.1858562034 + 45.1858520774)/2 = 29.6858541404 (new guess).
Error = new guess - previous value = 45.1858520774 - 29.6858541404 = 15.499997937.
15.499997937 > 0.01. As error > accuracy, we repeat this step again.
Step 6:
Divide 641 by the previous result. d = 641/29.6858541404 = 21.5927760397.
Average this value (d) with that of step 5: (21.5927760397 + 29.6858541404)/2 = 25.63931509 (new guess).
Error = new guess - previous value = 29.6858541404 - 25.63931509 = 4.0465390504.
4.0465390504 > 0.01. As error > accuracy, we repeat this step again.
Step 7:
Divide 641 by the previous result. d = 641/25.63931509 = 25.0006678318.
Average this value (d) with that of step 6: (25.0006678318 + 25.63931509)/2 = 25.3199914609 (new guess).
Error = new guess - previous value = 25.63931509 - 25.3199914609 = 0.3193236291.
0.3193236291 > 0.01. As error > accuracy, we repeat this step again.
Step 8:
Divide 641 by the previous result. d = 641/25.3199914609 = 25.3159643039.
Average this value (d) with that of step 7: (25.3159643039 + 25.3199914609)/2 = 25.3179778824 (new guess).
Error = new guess - previous value = 25.3199914609 - 25.3179778824 = 0.0020135785.
0.0020135785 <= 0.01. As error <= accuracy, we stop the iterations and use 25.3179778824 as the square root.
So, we can say that the square root of 641 is 25.31 with an error smaller than 0.01 (in fact the error is 0.0020135785). this means that the first 2 decimal places are correct. Just to compare, the returned value by using the javascript function 'Math. sqrt(641)' is 25.317977802344327.

determine whether WX and YZ are perpendicular,or, neither W(-7,6),X(-6,9)Y(6,3),Z(3,-6)
Answers
Answer: The lines WX and YZ are parallel.
Step-by-step explanation: We are given to check whether the lines WX and YZ are parallel, perpendicular or neither if the co-ordinates of the endpoints of both the lines are
W(3,4), X(5,7), Y(8,2) and Z(6,-1).
We know that the slope of a straight line passing through the points (a, b) and (c, d) is given by
m = d-b/c-a
So, the slope of the line WX is
m1 = 7-4/5-3 = 3/2
and the slope of line YZ is
m2 = -1-2/6-8 = -3/-2 = 3/2
Since , we get m1 = m2, so the two lines WX and YZ are parallel.
Thus, the lines WX and YZ are parallel.
They are not perpendicular, so if you mistyped something and it was parallel that would be the answer, or the answer is neither the mysterious angle form or perpendicular. Hope this helps.

Answers
Answer:
A and E
Step-by-step explanation:
The given problem shows a graph of a vertical line with an undefined slope, in which its equation is x = 3 (which matches Option A).
It is not considered a function because it has the same input for every given output. This means that regardless of its y-coordinate, its corresponding x-coordinate will always be x = 3.
The Vertical Line Test allows us to know whether or not a graph is actually a function. Remember that a function can only take on one output for each input. We cannot plug in a value and produce two output values. Since the graph represents a vertical line, it automatically fails the vertical line test. Therefore, it is not a function.
Because it is not a function, Options B, C, and D are invalid answers.
Hence, the correct answers are Options A and E.

<1 and <2 are complementary. Solve for the measure of <1.
<1 = 12x + 4
<2 = 9x + 2
A. 52
B. 4
C. 38
D. 8.3
Answers
Answer:
A) 52
Step-by-step explanation:
If < 1 and < 2 are complementary angles, then it means that the sum of their measures add up to 90°.
< 1 + < 2 = 90°
12x + 4 + 9x + 2 = 90°
21x + 6 = 90°
21x + 6 - 6 = 90° - 6
21x = 84°
21x/21 = 84°/21
x = 4
Substitute the value of x = 4 into < 1 and < 2:
m < 1: 12x + 4 = 12(4) + 4 = 52°
m < 2: 9x + 2 = 9(4) + 2 = 38°
Therefore, the correct answer is A) m < 1 = 52°.
