Answer:
(4000 in^2) * (1 ft/12 in)^2 = 27 7/9 ft^2
Step-by-step explanation:
4,000 Square Inches =
27.777778 Square Feet
Answer:
a. The equation should be
4x + 3y = $11.67
8x + y = $12.89
b. The price of one can of soup and the price of one loaf of bread is $1.355 and $2.09
The calculation is as follows:
here we assume the soup be x and bread be y
So, the equations are
4x + 3y = $11.67 .........(1)
8x + y = $12.89.........(2)
Here we need to multiply by 2 in equation 1
8x + 6x = $23.34
8x + y = $12.89
5y = $10.45
y = $2.09
Now x should be
8($2.09) + y = $12.89
x = $1.355
Hope this helps :)
You simply cross multiply. The correct answer is B. I know this becase I had the same exact question in my Staar review packet.
Answer:
x = 6
Step-by-step explanation:
Since the triangles are similar, we can use ratios to solve
20 24
--------- = ---------
5 x
Using cross products
20x = 24*5
20x = 120
Divide each side by 20
20x/20 = 120/2
x = 6
