Answer:
x=4
Step-by-step explanation:
3(-4x+5)=12
3(-4x) + 3(5)=12
-12x+15=12
<u> -15</u><u>=-15</u>
-12x=-3
-x = -4
Since your x is negative change the signs

Answer:
x = 6
Step-by-step explanation:
All triangle angles add up to 180 so:
90 + 5x + 6 + 54 = 180
5x + 150 = 180
5x = 30
x = 6
Answer: yes it is a right angle triangle
Step-by-step explanation:
a^2 + b^2 = c^2
8^2+ 5^2 = ?
64 + 25 = square root of 89
square root of 89 = 9.4
when we round 9.4 it is 9
so
22- (8+5) =
22 - 13 = 9
so our answer is correct
'of' in mathematics means multiplication
'is' in mathematics means equal
52% * x = 13
52/100 * x = 13
0.52x = 13
x = 13/0.52
x = 25
52% of 25 days is 13 days.
