area = 4 x 5.5 = 22 square inches
cost is 0.99 per sq. inch
22 * 0.99 = 21.78
cost is $21.98
Hi!
I can help you with joy!
First, use the Distributive Property:
4(2i-3)=20
8i-12=20
Now, move -12 to both sides, using the opposite operation:
8i=20+12
8i=32
Now, divide both sides by 8:
i = 4 (Answer)
Hope it helps.

• Rearrange first equation
x + 2y = 9
• Multiply the first equation by 3
3(x + 2y = 9)
• Rewrite equation 1
3x + 6y = 27
• Write both equations
3x + 6y = 27
3x - 6y = -15
• Subtract equation 1 from equation 2
3x + 6y = 27
-
3x - 6y = -15
• Write the reaming values
12y = 42
• Divide both side by 12 to solve for y
12y = 42 ➗ 12
• Write value of y
y = 3.5
• Substitute the value of y into one of the original equations
2(3.5) = -x + 9
• Use algebra and sole for x
7 = -x + 9
x = 9 - 7
x = 2
• Write final point
