Answer:
2.36
Step-by-step explanation:
order of operations : pemdas
parenthesis, exponents
multiplication, division
addition, substraction
first parenthesis, so
(32-4) = 28
parenthesis again
[10+28] = 38
now you have
90/38 = 45/19 = 2.36
To find out how many students were left handed, we know that if 90% were right handed, then 10% have to be left handed.
30 students x 0.10 = 3 students left handed
Answer:
1. VW = 22
2. x = 87
Step-by-step explanation:
Question 1:
SU = 11 (given)
SU = ½(VW) => midsegment theorem
11 = ½(VW) => Substitution
Multiply both sides by 2
2*11 = VW
VW = 22
Question 2:
UV = x + 13
RT = x - 37
RT = ½(UV) => Midsegment Theorem
x - 37 = ½(x + 13) => Substitution
Multiply both sides by 2
2(x - 37) = x + 13
2x - 74 = x + 13
2x - 74 + 74 = x + 13 + 74
2x = x + 87
2x - x = x + 87 - x
x = 87
