0.96 yards of cloth was needed to make 2 bags.
Step-by-step explanation:
Let,
x be the yards of cloth used for each bag
y be the yards of cloth used of each apron
According to given statement
4x+5y=8.22 Eqn 1
5x+4y=7.44 Eqn 2
Multiplying Eqn 1 by 5
Multiplying Eqn 2 by 4
Subtracting Eqn 4 from Eqn 3
Dividing both sides by 9
Putting y=1.26 in Eqn 1
Dividing both sides by 4
Cloth required for one bag = 0.48 yards
Cloth required for 2 bags = 0.48*2 = 0.96 yards
0.96 yards of cloth was needed to make 2 bags.

Answer: A) g(x) = 3x - 14
<u>Step-by-step explanation:</u>
Solve the equation for y and replace y with g(x):
y - 3x = -14
y = 3x - 14
g(x) = 3x - 14
Answer:
x=4
Step-by-step explanation:
Let's solve your equation step-by-step.
−x=2−3x+6
Step 1: Simplify both sides of the equation.
−x=2−3x+6
−x=2+−3x+6
−x=(−3x)+(2+6)(Combine Like Terms)
−x=−3x+8
−x=−3x+8
Step 2: Add 3x to both sides.
−x+3x=−3x+8+3x
2x=8
Step 3: Divide both sides by 2.
2x/2 = 8/2
x=4
Answer: 23 in
Step-by-Step Explanation:
Height (h) = 18 in
Base (b) = ?
Area (A) = 207 sq. in
We know,
Area of a Triangle = 1/2 * b * h
Therefore,
1/2 * b * h = 207
1/2 * b * 18 = 207
b * 9 = 207
9b = 207
b = 207/9
=> b = 23
Base (b) = 23 in
M<S = 1/2(80-40)
