BRAINLIEST ANSWER!!
During the summer, you work 30 hours per week at the gas station and earn $8.75 per hour. You also work as a landscaper for $11 per hour and can work as many hours as you want. You want to earn a total of $400 per week. How many hours, t, must you work as a landscaper?
Identify an equation that can be used to answer the question.
A) 30t=400-8.75(11)
B) 8.75+11+400=30+t
C) 8.75t+11t=400
D) 30(8.75)+11t=400
Solve the equation to find the number of hours you must work as a landscaper.
You must work ___ hours as a landscaper.
Answer:
1. 30(8.75) + 11t = 400
2. 12.5 hours
Step-by-step explanation:
1. What is given is you work for 30 hours per week at a gas station for $8.75 an hour. You also work as a landscaper for $11 an hour. You want to a make a total of $400 per week.
30 hours and $8.75 an hour would be equivalent to 30(8.75)
We don’t know how many hours you work as a landscaper but you earn $11 an hour, which is equivalent to 11t
Finally, you want to earn a total of $400 a week, which means the sum equals 400
30(8.75) + 11t = 400
2. 30(8.75) = 262.5
400 - 262.5 = 137.5
137.5 / 11 = 12.5

Nathalie has some quarters, dimes, and nickels. The ratio of the number of quarters to the number of dimes to the number of nickels that she has is $9:3:1$. The total value of these coins is $18.20. How many coins does Nathalie have?
Answer:
the answer is 91
Step-by-step explanation:
One group of 9 quarters, 3 dimes, and 1 nickel has the value of $9 \times 25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins she has are in this same ratio 9:3:1, we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Because the total value of her coins is 18.20and 18.20\2.60=7, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has 7 times 13 = 91 coins in total.
Each of these group contains 13 coins, so she has total 91 coins.
What are nickles, dimes, quarters and cents?A dollar is further divided into some majorly used parts as:
A cent = 100th part of a dollar = $1/100 = $0.01
A nickle= 20th part of a dollar = $1/20 = $0.05
A dime = 10th part of a dollar = $1/10 = $0.10
A quarter = 4th part of a dollar = $1/4 = $0.25
One group of nine quarters, 3 dimes, and 1 nickel has the value of $9
25 + 3 times 10 + 5=26 cents or 2.60 in total.
Since the coins Nathalie has are in this same ratio 9:3:1, thus we can split her coins up into groups of 9 quarters, 3 dimes, and 1 nickel, with each group having a value of 2.60
Due to the total value of her coins is 18.20
18.20/2.60=7,
Hence, she has 7 of these groups of coins.
Each of these group contains 13 coins, so she has total ;
7 x 13 = 91 coins

A ladder is leaning against a house so that the top of the ladder is 12 feet above the ground. The angle the ladder makes with the ground is 51°. How long is the ladder?
12•sin51°
12/cos51°
12•cos51°
12/sin51°
None of these
Answer:
12/sin5°
Step-by-step explanation:
This angle can be calculated using the law of sine:
sin(angle)=opposite cathete/hypothenuse
sin(angle)=wall/ladder
In this exercise we want to calculate the length of the hypotenuse (ladder), so the equation is changed afterwards.
sin(angle)=wall/ladder
sin(angle)*ladder=wall
ladder=wall/sin(angle)
Now the given values are used:
ladder=wall/sin(angle)
ladder=12ft/cos(51°)

Charlie wants to order lunch for his friends. He'll order sandwiches and a $2 kid's meal for his little brother. Charlie has $32. How much can he spend on each sandwich if they are all the same price? "choose two answers" A) Inequality: 2x+6<32. B)Answer $5 or less. C) Inequality 6x+2 ≤32.D)Answer $13or less. E) Inequality 2x+6≤32. F) Inequality 6x+2≥32
So, obviously, since one of the prices is given, which is $2.00 for the kid's meal, then you need to subtract that from his $32.00 total to know what number you need to divide into the 6 sandwiches. So, so far you have $30.00. If you divide $30.00 by the 6 sandwiches, you will find out he could only spend $5.00 per sandwich. So basically, you got the expression of (32 -2) / 6 in order to find out that your answer is $5.00. Looking at you answer choices, I can see right away that D is correct. For the inequality, I can see that B would be the correct answer for this problem because he can't go over budget. So, your answers are B and D.

Explain how you would solve the equation -7 + x = 12 using the properties of equality. (Site 1)
Given problem:
Solve using the property of equality;
-7 + x = 12
The properties of equality are;
Addition. Definition. If x = y, then x + c = y + c. ...
Subtraction. Definition. If x = y, then x – c = y – c. ...
Multiplication. Definition. If x = y, then xc = yc. ...
Division. Definition. If x = y and c is not equal to 0, then x / c = y / c
Now;
- 7 + x = 12;
base on the properties of equality, to eliminate -7, add +7 to both sides;
-7 + 7 + x = 12 + 7
x = 19
Based on the properties of equality, the solution is 19

A cheese pizza at Chicago's Deep Dish pizza costs $7. Each topping costs an additional $0.75. A cheese pizza at Brooklyn's cost $12. Each topping costs an additional $0.50. Write an equation that represents how many toppings, y, must be added so that the two pizzas cost the same?
Step-by-step explanation:
Let the number of toppings be y
If cheese pizza at Chicago's Deep Dish pizza costs $7 and each topping costs an additional $0.75, the total amount of the dish pizza will be expressed as;
$7 + $0.75y ..... 1
Also, if a cheese pizza at Brooklyn's cost $12 and each topping costs an additional $0.50, then the total cost of cheese pizza will be;
$12 + $0.50y ........ 2
If the two pizzas cost the same, then equation 1 will be equal to equation 2 as shown;
7+0.75y = 12+0.50y
Make y the subject of the formula to generate the required equation for y:
0.75y-0.50y = 12-7
0.25y = 5
divide both sides by 0.25
0.25y/0.25 = 5/0.25
y = 5/0.25
y = 20
Hence the equation that represents how many toppings, y, must be added so that the two pizzas cost the same is y = 5/0.25 and the number of toppings added is 20.

Step-by-step explanation:
All decimals are over a number in the power of ten. If you say the decimals out loud you would say "26 hundredths " and "79 hundredths" so you place the decimals over 100 and then simplify.

Find 4ab when (a+b)=15 and (a-b)=12
Answer:
81
Step-by-step explanation:
here,
(a+b)=15 -------(1)
(a-b)=12 -------(2)
Equating the equation (1) and (2)
a + b = 15
a - b = 12
(b gets cancelled having opposite signs)
or, 2a = 27
or, a = 27÷2
a = 13.5
then, putting value of a in equation (1)
a+b=15
or, 13.5 + b=15
or, b=15-13.5
b=1.5
lastly,
4ab = 4×13.5×1.5
= 81
hope it helps!!

Answer:
Step 1: 4 x − 3 − 2 x − 10
Step 2: 2 x − 13
Step-by-step explanation:
Given the expression;
(4 x − 3) − 2 (x + 5)
The following steps/ procedure are to be taken when simplifying the expression.
open the parenthesis
(4 x − 3) − 2 (x + 5)
= 4x-3 -2(x)-2(5)
= 4x-3-2x-10
collect the like terms
= 4x-2x-3-10
simplify the resulting expression
= 2x-13
Hence the procedure that correctly simplifies the expression are:
Step 1: 4 x − 3 − 2 x − 10
Step 2: 2 x − 13

Answer:
1.) 12 hours 2.) She made a multiplying error in the table.
Step-by-step explanation:
1.)
First, let's find the slope of this equation:
m = 135 - 81 / 5 - 3
m = 54/2
m = 27
Therefore, the equation should be y = 27x.
Now we substitute 324 for y and solve for x:
324 = 27x
12 = x (Divided 27 on both sides.)
Therefore, someone would have to work 12 hours in order to earn $324.
