Answer:
42
Step-by-step explanation:
You can use proportions to solve this problem.
=![\frac{7cm}{xkm}](https://tex.z-dn.net/?f=%5Cfrac%7B7cm%7D%7Bxkm%7D)
Now just cross multiply.
5cm*Xkm=7cm*30km
you can simplify the cm and km since its multipying.
5x=210
x=42
Answer:
1st equation: 3(12) - 12 = 24
2nd equation: 36 - 12 = 24
The value of bh for b =12 and h = 2 is 24
<h3>How to evaluate the expression?</h3>
The expression is given as:
bh
Where
b = 12 and h = 2
So, we have:
bh = 12 * 2
Evaluate
bh = 24
Hence, the value of bh for b =12 and h = 2 is 24

Answer:
1
Step-by-step explanation:
We pick two points on the line and use the slope formula
Two points ( 0,2) and ( 1,3)
m = ( y2-y1) / ( x2-x1)
= ( 3-2) /( 1-0)
= 1 /1
= 1
