than times 4 times the
number. Find the number.
Answer:
18
Step-by-step explanation:
Let's make this information into an equation.
We'll use 'x' whenever the problem says "a number".
Equation:
5x + 18 = 36 + 4x
How did I get to this equation?
Now, let's solve.
Solve:
5x + 18 = 36 + 4x
Subtract 18 on both sides:
5x + 18 = 36 + 4x
-18 -18
5x = 18 + 4x
Subtract 4x on both sides:
5x = 18 + 4x
-4x -4x
x = 18
Therefore, "the number" is 18.
B evaluate the expression how much will George pay for carpeting
Answer:
The expression of the total amount George pay for carpeting is x = 385 × 3.50 .
$ 1347.5 will George will pay for carpeting .
Step-by-step explanation:
Formula
Area of the rectangle = Length × Breadth
Area of a square = a²
Where a is the side of the square .
As given
George wants to put carpeting in a rectangular living room and a square bedroom.
The length and width of the living room is 12 feet by 18 feet one side of the square bedroom is 13 feet .
Area of the living room = 12 × 18
= 216 ft ²
Area of the bedroom = 13²
= 169 ft ²
Total area = Area of the living room + Area of the bedroom
= 216 + 169
= 385 ft ²
As given
it will cost 3.50$ per foot to carpet the rooms .
First part
Let us assume that the total amount george will pay for carpeting be x .
Than
x = Total are of the living room and bedroom × cost of per foot carpeting .
x = 385 × 3.50
Second part
x = Total are of the living room and bedroom × cost of per foot carpeting .
x = 385 × 3.50
x = $ 1347.5
Therefore the $ 1347.5 will George will pay for carpeting .
B. 3.99x + 12.25 =77.49
C. 12.25(x+3.99) = 77.49
D. 12.25x+3.99= 77.49
Answer:
D. 12.25x +3.99 = 77.49
Step-by-step explanation:
various supplies. They still plan to purchase balloons to decorate the room at a cost of $0.65 per balloon. Which of the following inequalities represents the total number of
balloons, b, they can purchase and not spend over their budgeted amount?
Answer:
There are two inequalities that represent the total number of
balloons, b, they can purchase and not spend over their budgeted amount:
0.65b ≤ 70
0.65b + 225 ≤ 295
Step-by-step explanation:
1. Let's review the information given to us to answer the question correctly:
Budget to plan the event = $ 295
Expenses on supplies so far = $ 225
Cost of each balloon = $ 0.65
2. Which of the following inequalities represents the total number of
balloons, b, they can purchase and not spend over their budgeted amount?
1. Let's find how much of the budget is still available:
Budget available = Budget to plan the event - Expenses on supplies so far
Budget available = 295 - 225
Budget available = $ 70
2. Let's find the inequality that represents the total number of
balloons, b, they can purchase and not spend over their budgeted amount.
Number of balloons ≤ Budget available/Cost of each balloon
Replacing with the values we know, we have:
b ≤ 70/0.65
0.65b ≤ 70
or we can write it also including the total budget this way:
Number of balloons ≤ Budget to plan the event - Expenses on supplies so far /Cost of each balloon
Replacing with the values we know, we have:
b ≤ (295 - 225)/0.65
0.65b ≤ 295 - 225
0.65b + 225 ≤ 295
