Answer:
x=4
Step-by-step explanation:
I used cross multiplication
7+2x/3=5
7+2x/3=5/1
7+2x(1)=5(3)
7+2x=15
2x=15-7
2x=8
x=4
Answer:
x = 4
Step-by-step explanation:
The goal is to get x by itself.
1. Multiply both sides by 3 and you are left with:
7 + 2x = 15
2. Subtract 7 from both sides and you are left with:
2x = 8
3. Simplify by dividing each side by 2 and you are left with the answer:
x = 4

David wants to earn more than $26 trimming trees. He charges $6 per hour and pays $4 in equipment fees. What are the possible numbers of hours David could trim trees? Use for the number of hours. Write your answer as an inequality solved for
Answer:
The inequality is :
6h - 4 > 26
The possible numbers of hours David could trim trees is more than 5 hours
Step-by-step explanation:
David wants to earn more than $26 trimming trees. He charges $6 per hour and pays $4 in equipment fees.
Let the number of hours David works for be represented by h
More than means greater than , hence we use the inequality sign >
Hence, we have the inequality
$6 × h + $4 > $26
6h - 4 > 26
6h > 26 + 4
6h > 30
Divide both sides by 6
6h/6 > 30/6
h > 5
Hence, if David want to earn more than $26 he has to trim trees for more than 5 hours

A triangular pyramid and its net are shown. Rain uses the calculations below to conclude that the surface area of the triangular pyramid is 238.5 square inches. 3 x 10 x 13) + ( x 10 x 8.7) 3 (65) + 43.5 238.5 Is Rain correct? Use the drop-down menus to explain your reasoning.
Answers
Answer:
Yes, Rain is correct
238.5 square inches
Step-by-step explanation:
Surface Area of a Triangular Pyramid,A = 1/2(a × b) + 3(1/2 × b × s)
= (1/2 × 10 × 8.7) + 3(1/2 × 10 × 13)
= 43.5 + 3(65)
= 43.5 + 195
= 238.5 square inches
The surface area of the triangular pyramid = 238.5 square inches
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.
What is an equation?An equation is an expression that shows the relationship between two or more numbers and variables.
From the net attached:
Surface area = 3(1/2 * 10 * 12) + (1/2 * 10 * 8.7)
Surface area = 223.5 in²
The surface area of the net of the triangular pyramid is 223.5 in². Rain is not correct.

The perimeter of a rectangle is 208 inches. The ratio
of its length to its width is 5:3. What are the
dimensions of this rectangle?
A. 60 in by 44 in
B. 65 in by 39 in
C. 68 in by 36 in
D. 72 in by 32 in
Answers
Answer:
The dimensions of this rectangle are 65 in by 39 in ⇒ B
Step-by-step explanation:
Let us use the ratio method to solve the question
∵ The perimeter of the rectangle = 2(length + width)
∵ The perimeter of a rectangle is 208 inches
∴ 208 = 2(length + width)
→ Divide both sides by 2
∴ 104 = length + width
∵ The ratio of its length to its width is 5: 3
∴ The sum of the ratios = 5 + 3 = 8
→ By using the ratio method
→ length : width : length + width
→ 5 : 3 : 8
→ x : y : 104
→ By using cross multiplication
∵ x × 8 = 5 × 104
∴ 8x = 520
→ Divide both sides by 8
∴ x = 65
∵ y × 8 = 3 × 104
∴ 8y = 312
→ Divide both sides by 8
∴ y = 39
∵ x and y represents the length and the width of the rectangle
∴ The length = 65 inches
∴ The width = 39 inches
∴ The dimensions of this rectangle are 65 in by 39 in
