Answer:
Jack is 24
Step-by-step explanation:
Luke : jack
3 2
We know like is 36
3*12 = 36, so we need to multiply by 12
Luke : jack
3*12 2*12
36 24

Answer:
80km
Step-by-step explanation:
To solve this problem, we need to cross multiply. Lets input the values (1.2, 1.0, 96) as shown below:

Next we cross multiply. We multiply 1.2 and x, and we multiply 96 and 1.0.
1.2(x) = 1.2x
96 x 1.0 = 96
Now, lets put the values above back into the equation:
1.2x = 96
Lets solve this equation. First we divide 96 by 1.2.
1. 
2. 
This means that our answer is 80km.
Answer:
-4x^2+5x-28
Step-by-step explanation:
Expand -7(x^2 +4) = 3x^2+5x-7x^2-28
Simplify 3x^2+5x-7x^2-28 = -4x^2+5x-28
Answer:
Estimate the surface area of a cube with side length 9.9 in.
A) 100 in²
B) 400 in²
C) 600 in²
D) 1000 in²
Step-by-step explanation:
9.9 to the nearest whole number is 10
We know the side length of the cube is 10
We work out the area of face and multiply by 6.
10 x 10 = 100
100 x 6 = 600 in²
