translate, call the number, n
Eight more than (8+) twice a number increased by 3 (2(n+3)) is equal to (=) 79 (79)
8+2(n+3)=79
minus 8 both sides
2(n+3)=71
divide both sides by 2
n+3=35.5
minus 3 both sides
n=32.5
the number is 32.5
Answer:
Shaded area is 392
Step-by-step explanation:
The triangles on the left have heights 14 and 14, the ones on the right have 20 and 8.
The bases are equal, so we can compute them as (40-12)/2 = 28/2 = 14
The triangles have areas:
14*14/2 = 14*7 = 98
14*14/2 = 14*7 = 98
20*14/2 = 20*7 = 140
8*14/2 = 8*7 = 56
note that the triangles on the left and the ones on the right have the same total area! That would have happened no matter what the height split was!
The total area is 98+98+140+56 = 196 + 196 = 392
Answer: D) 0.78
Step-by-step explanation:
Add all the given probabilities to find the answer:
45/100 + 18/100 + 15/100 = 78/100 = 78% or 0.78
Your breaking the problem down.
8 x (40 + 7)
You notice how in the second part of the equation, the (8 x 7) the 40 is not there?
Your answer will be 8 x (40 + 7) = (8 x 40) + (8 x 7)
