The answer to the question
We will use the INVERSE OPERATION of multiplication which is division. Lets do it:-
3x = 27
27 ÷ 3 = x
27 ÷ 3 = 9
x = 9
CHECK OUR WORK:-
3x = 27
x = 9
3 · 9 = 27
We were RIGHT!!!!!
So, x = 27.
Hope I helped ya!!! xD
Answer:
n<-1
Step-by-step explanation:
Distribute 5 and -5 into each parenthesis respectively: 40n+35<5-5n-15
Combine like terms: 40n+35<-5n-10
Add 5n to both sides: 45n+35<-10
Subtract 35 from both sides: 45n<-45
Divide both sides by 45: n<-1
Answer:
3
Step-by-step explanation:
8x and 7x + 3 are vertically opposite angles.
Vertically opposite angles are equal,
8x = 7x + 3
8x - 7x = 3
x = 3
