help i need this done asap
Answer:
look at explanation
Step-by-step explanation:
<ABC and <CBD are supplementary, meaning when added together they equal 180 degrees. So that means 5x + 2x + 5 = 180. Add 5x and 2x together to make 7x, so you are left with 7x+5 = 180. Subtract 5 from both sides to get 7x = 175. Divide 7 on both sides to get x by itself, so you are left with the result x = 25, proving that x does equal 25 degrees.

Answer:
63.8
Step-by-step explanation:
63.77 so you look at the hundredths 5 or higher round up
63.8 is the required answer
The given number is 63.7786879082, we have to round to the nearest tenth
How to round nearest 10th?
To round the decimal number to its nearest tenth, look at the hundredth number. If that number is greater than 5, add 1 to the tenth value.
63.7786879082
We can see that 100th number i. e 7 is greater than 5, so add 1 to the tenth value
So we get 63.8

Please help? I don’t get this it’s really tough...
Answer:
D. 200-2/3x=2/5
Step-by-step explanation:
You can tell that one side of the equation is going to have only 2/5 because the problem said there was 2/5 of a ton left. You can also figure out that the equation should say 200-2/3x because the problem said that the conveyor belt removes 2/3 of a ton per minute. So, the equation should be...
200-2/3x=2/5, which is D.
Hope this helps c:
Answer: D
Step-by-step explanation:
The 2/3 is the rate and there is 2/5 leftover from the original 200 tons.

triangle abc with vertices a(-3 2) b(-1 7) and c(6 1) in the x-axis
Answer:
A'(-3, -2), B'(-1, -7), C'(6, -1)
Step-by-step explanation:
Transformation is the movement of a point from its initial location to a new location. If an object is transformed, all its points are also transformed. Types of transformation are reflection, rotation, dilation and translation
If a point X(x, y) is reflected across the x axis, the new location is X'(x, -y).
If triangle ABC is reflected across the x axis, the new vertices are A'(-3, -2), B'(-1, -7), C'(6, -1)
1. Use the figure below to answer the questions.
(a) Solve for x.
Let's see what to do buddy...
_________________________________
The sum of the angles of each n-sided figure is found in the following equation :
[tex](n - 2) \times 180 [/tex]
The question's figure is 5-sindes figure
so the sum the angles equal :
[tex](5 - 2) \times 180 = 3 \times 180 = 540 \\ [/tex]
So we have :
[tex]90 + 107 + 144 + 138 + x = 54 0 \\ [/tex]
[tex]479 + x = 540[/tex]
Subtract the sides of the equation minus 479
[tex]x = 540 - 479[/tex]
[tex]x = 61[/tex]
And we're done.
Thanks for watching buddy good luck.

At first, they swim at different rates, but if you compare the last two (17/425 and 20/520) Eva swam the fastest.
Answer:
Sarah swims faster
Step-by-step explanation:
To get the answer, divide the time by the distance. 17/425 is greater than 20/520, so sarah swims faster

Michael Fenton sells plumbing supplies to contractors. He earns 3% commission on the first $15,000
in sales, 5% on the next $15,000, and 8% on sales over $30,000. Last month he sold $52,000 worth
of plumbing supplies. What was his total commission?
Answer:
His total commission was: $2,960
Step-by-step explanation:
The commissions that Michael Fenton earns by selling plumbing supplies to contractors has three levels:
On the first $15,000 in sales, he earns 3%
On the next $15,000 in sales, he earns 5%
Over $30,000 in sales, he earns 8%.
Last month he sold $52,000 worth of plumbing supplies. His commissions will be calculated according to the levels reached:
The first $15,000 gave him 3%*15,000=0.03*15,000=$450
From the $52,000 sales, there remains $52,000 - $15,000 = $37,000 for the next levels.
The next $15,000 gave him 5%*15,000=0.05*15,000=$750
Now $37,000 - $15,000 = $22,000 remain for the last level.
Michael earned 8% of $22,000 = 0.08*22,000 = $1,760
His total commission was: $450 + $750 + $1,760 = $2,960

One half of a number increased by 3 is five less than two thirds of the number
Answer:
12 is thy number lol
Step-by-step explanation:
1/2x + 3 = 5 - 2/3x
Subtract the 1/2x
You get 3 = 5 - 1/6x
Subtract the five.
-2 = -1/6x
Multiply by -6
x = 12
The number who's one-half increased by 3 is five less than two-thirds of itself is 48.
What is an Expression?In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.
Let the unknown number be represented by x.
Given the statement that "One half of a number increased by 3 is five less than two-thirds of the number". Therefore, the statement as an expression can be written as,
(1/2)x + 3 = (2/3)x - 5
Solving the equation for x,
3 + 5 = (2/3)x - (1/2)x
8 = (4/6)x - (3/6)x
8 = (1/6)x
x = 8 × 6
x = 48
Hence, the number who's one-half increased by 3 is five less than two-thirds of itself is 48.

Given the equation 4x + 2y = 10, find the value of y that
corresponds to a value of 3 for x.
Answer:
-1
Step-by-step explanation:
you already know the value of x is 3, so you just solve to figure out what y would be to equal 10
4(3) + 2(y) = 10
4(3) + 2(-1) = 10

Suppose J is between H and K. Use the Segment Addition Postulate to solve for x. Then find the length of each segment. If HJ=x+10 JK=9x KH=14x−58 a) Draw a sketch of the segments described above b) Write an equaation using the segment addition postulate that will help you solve the problem ___+ ___= c) combine like terms ( x terms on one side of the equal sign and numbers in the other side of the equal sign) ____ = ____ d) x= __ HJ= __ JK= __ HK= __
Answer:
x= 17
HJ= 27
JK= 153
HK= 180
Step-by-step explanation:
If HJ=x+10
JK=9x
KH=14x−58
a) The diagram of sketch of the segments described above is attached to this answer.
b) KH = HJ + JK
14x - 58 = (x + 10) + 9x
14x - 58 = x + 10 + 9x
c)
14x - 58 = x + 10 + 9x
14x - 58 = 10x + 10
Collect like terms
14x - 10x = 10 + 58
4x = 68
Divide both sides by 4
4x/4 = 68/4
x = 17
d)
x= 17
HJ= x + 10
= 17 + 10
= 27
Hence, HJ = 27
JK= 9x
= 9 × 17
= 153
Hence, JK = 153
HK=14x −58
HK = 14 × 17 - 58
= 238 - 58
= 180
Hence, HK = 180
