Answer:
Step-by-step explanation:
What we're basically looking for here are ways to get 100 using these numbers.
My immediate first thought was "can we divide the 7's by some 7's to get 100?"
I know that 
, so I had the idea to make it 
. This means that we can use the number 7 four times in the equation 
.
However, we're still missing a 1 that we need to include. This is easy, we can just multiply 
by 1.
So in conclusion, we get 
Hope this helped!
Answer:
(-5/6)x - 1
Step-by-step explanation:
the equation is given by: y = mx + b
m = slope
b = y intercept
m = -5/6
y intercept = -1
f(x) = (-5/6)x - 1
X = -30
First combine like terms (0.02x - 0.01x = 0.01x) (-4 - 2 = -6)
0.01x - 6 = -6.3
Then add 6 (-6 + 6 = 0) (-6.3 + 6 = -0.3)
0.01x = -0.3
Then divide by 0.01 to find what x is alone (0.01x ÷ 0.01 = x) (-0.3 ÷ 0.01 = -30)
x=-30
Number 1
37.50 divide by 5.25 and the answer is 7
Find find the area of the closet and subtract it from the area of the (gym and closet)
Area of gym and closet = L x w = 5 x 4 = 20
Area of the closet = L x w = 2 x 1 = 2
Area of gym only = (gym and closet) - closet
= 20 - 2
= 18
Answer: 18 cm²
