Answer:
128,8,28,36
Step-by-step explanation:
if u multiply 32 times 4 u get 128 but if u subtract them u get 28
but if u divide them then u get 8 but if u also add them u get 36
A=1 and 2
B=2 and 4
C=1,2,7 and 14
D=1,2,4,and 8
Answer:
D(x=1).
Step-by-step explanation:
2(5x+8)=6x+20
10x+16=6x+20
10-6x+16=6x-6x+20
4x+16=20
4x+16-16=20-16
4x=4
4x/4=4/4
x=1
7th grade has 3 boy out of 10 students
probability of picking a boy is 3/10
8th grade has 9 boys out of 12 students are boys
probability of picking a boy is 9/12 reduced to 3/4
3/10 x 3/4 = 9/40 probability of picking 2 boys
