4m-10m=5-2
-6m=3
m=-3/6
M=-1/2
Now let's check if this is correct-6•(-1/2)=6/1•1/2=6/2=3 ,yes correct I think
Answer:
1. 800 cm squared
2. 152 cm squared
Step-by-step explanation:
let break it down
1. 800 cm squared
20 * 7 = 140
20 * 6 = 120
38 - 20 = 18
30 * 18 = 540
now add all of them together
140 + 120 + 540
100 + 100 + 500 = 700
40 + 20 + 40 = 100
700 + 100 = 800 cm squared
2. 152 cm squared
16 * 10 = 160
2 * 2 + 2 * 2 = 4 + 4 = 8
160 - 8 = 152 cm squared
again, we're assuming that both triangles are similar, and thus using proportions.
we do not use the -10, because whatever value "x" may be, can't be negative or even 0.
Answer:
10 1/4
Step-by-step explanation:
Carls age = 12 5/6 - 1 1/3
12 5/6 - 1 1/3
11 (5 - 2) / 6 = 11 3/6
Jane's age = carl's age - 1 1/4
11 3/6 - 1 1/4
10 (12 - 6) / 24 = 10 6/24 = 10 1/4
