we are given
step-1: Factor terms
now, we can plug these values
and we get
=
step-2: Cancel common terms
we get
=
we can again cancel numerator and denominator
and we get
=
.............Answer
A) 20.6 x 11.4 : 21 x 11 = 252
6.9 x 3.6 : 7 x 4 = 28
252/28 = 9
b) Each number has been multiplied by 10 so for 4 numbers 9 x 10000 = 90000
Answer:
Step-by-step explanation:
x + 12 = y
x = y - 12
The answer is 80’, because is the corresponding angle of 1, so it must be the same answer as 1 angle.
Answer:
Step-by-step explanation:
b/c these are similar triangle we can say this ratio of the two triangles is true
15/x = 31/(44+x)
now just use algebra to solve for x
15*(44+x) = 31x
660+15x = 31x
660=16x
41.25 =x
41.3 looks good
