Answer:
Step-by-step explanation:
The answer to the first one is:
x=-5/4y+-1/2. Why?
In the equation 8x+10y=-4, you subtract 10y form each side which leaves you with 8x=-10y-4. Right? Then you divide each side by 8 which gives you the answer
The answer to the second one is the same answer to the first problem. Why? Because you can already divide each side which gives you x=-5/4y+-1/2.
Hope this helps :^)
Answer:
$10
Step-by-step explanation:
Subtract the price of the keychain, $7, from the total to find the price of the 3 t-shirts:
$37 - $7 = $30
The 3 t-shirts cost a total of $30.
We assume all t-shirts have the same price.
price of 1 t-shirt = $30/3 = $10
Answer: $10
The surface area of the rectangular prism is 52 square feet (
), if the height is 4 feet, width is 3 feet and depth is 2 feet.
Step-by-step explanation:
The given is,
A rectangular prism of
Let, h - height of the rectangular prism
w - Width of the rectangular prism
d - Depth of the rectangular prism
Step:1
From given,
h = 4 feet
w = 3 feet
d = 2 feet
Step:2
Formula to calculate the surface area of the rectangular prism is,

Substitute the values of w,d and h
= 2 [(3×2) + (4×2) + (4×3)]
= 2 (6+8+12)
= 2 × 26
= 52
A = 52 Square feet
Result:
Thus the surface area of the rectangular prism is 52 square feet (
), if the height is 4 feet, width is 3 feet and depth is 2 feet.
F^-1(x) = sqrt 2(-5+x)/2, - sqrt 2(-5+x)/2
