Answer:
x= -9
Step-by-step explanation:
5(x+2)=3x-8
Distributive Property
5x+10=3x-8
Subtract 10 and 3x from each side and add it across the equation to put the like terms together.
5x-3x=-8-10
2x= -18
x= -9
Hope this helps :)
Answer:
(a)
Given expression: 49% of 162
we can write 49% as
then;
Therefore, the estimate of the given expression is, 79.38.
(b)
Using mental math to calculate 49% of 162.
Mental math is used as a way to calculate an estimate quickly.
We can write 49% = 50% -1%
(50%-1%) of 162 = 50% of 162 -1% of 162
so,
50% of 162 =
and
1% of 162 =
Now, subtract these we get;
81 - 1.62 = 79.38
Therefore, by using mental math 49% of 162 is, 79.38
Answer:
t = 5 or t = 0
Step-by-step explanation:
Solve for t:
12 t (t - 5) = 0
Divide both sides by 12:
t (t - 5) = 0
Split into two equations:
t - 5 = 0 or t = 0
Add 5 to both sides:
Answer: t = 5 or t = 0
