Answer:
Step-by-step explanation:
1/5x = 12
x = 12 × 5
x = 60
( By using transposing method )

You can recheck it by calculating
60/5= 12
Answer:
X=98°
Step-by-step explanation:
53° + 45° = 98
98-180= 82
every triangle is always equal o 180°
so... 53°+ 45°+ 82° = 180
to find x you need to subtract 82 from 180 which is 98
<em>remember its important to find the inner degree before the outer.</em>
Answer:
Step-by-step explanation:
2x(x - 3) + 7(x - 3)
2x^2 - 6x + 7x - 21
reduce
2x^2 + x - 21
if this is equal to 0 then:
2x^2 + x - 21 = 0
factored:
(2x + 7)(x - 3) = 0
How that was done:
Divide the (2x^2) into (2x) and (x).
Divide the (-21) into (+7) and (-3). You choose these numbers so that their sum, when multiplied by (2x) and (-3), adds up to (+x).
