Answer: 80
1 hour= 60mins
So to know how many words can she type in 1 min, we do the math "4800 : 60"
The operation of this problem is B multiplication
Hello! To solve this problem, we should do 180/225. When you do that, you get 0.8. But then, you must multiply by 100 to get your percentage. When you do that, the product should be 80. 180 is 80% of 225.
Answer:
33
Step-by-step explanation:
Let's call their ages m and b.
We have:
m = b + 12
m - 17 = 4(b - 17) → m = 4b - 51
b + 12 = 4b - 51
3b = 63
b = 21
m = 21 + 12 = 33
First,multiply the -2 by everything in the brackets
so that's, -6x-(b-4x)+(x+6b)
then combine like terms
that's -6x-(7b-3x) which is
-3x-7b I believe
