Answer:
40/7 = 5 5/7
Step-by-step explanation:
All you have to do is just add up all the sides to find the perimeter
Likely because she has 1 out of 6 chances of rolling a 4
Answer:
x = 5/4
y = 7/4
Step-by-step explanation:
The smaller triangle and the larger one are similar, so the sides are proportional.
(x+5)/5 = 10/8
x/5 + 1 = 1/4 + 1 . . . . . divide it out
x/5 = 1/4 . . . . . . . . . . .subtract 1
x = 5/4 . . . . . . . . . . . . multiply by 5
___
For y, you can do exactly the same computations, replacing every instance of 5 with a 7. Then you get ...
y = 7/4
So you do 93 times 60 because it said you have to do 6 ten times and that equal 5580
