Answer:
Annie's height= 49 cm
Her brother's height= b+ 49
Let the sum be represented as x
x- 49 = b
I think the answer is 28 prices of spearmint gum because 32/8=4 so if you multiply 7*4 you get 28??????
Hope this helped!!! Sorry if I’m wrong.
Answer:
20,9
Step-by-step explanation:
this is how I did=x=1st, y=2nd; x=4y-16 and x+y=29; thus 4y-16+y=29; 5y-16=29; 5y=45; y=45/5=9, once you know y=9, put in equation, 4y-16=×, (4*9)-16=x, 36-16=x, 20=x
5d=470:
in this case we have to divide both sides by 5:
d=94
8a=47:
in this case we have to divide both sides by 8:
a=5.875
as a general rule, if you want to find out a value of a in
ab=c
you have to divide both sides of the equation by b (if it's not zero); then you will have left:
a=c/b
and if you calculate c/b, this will give you the answer
