Answer:
a. 12 years
b. 30 years
Step-by-step explanation:
a) Assume Liaqat's age is x. His age would be:
5x + 10 = 70
5x = 70- 10
x = (70 - 10) / 5
x = 12
<em>Liaqat is 12 years old.</em>
b. Assume his uncle's age is y;
4y - 10 = 130
4y = 130 - 10
y = (130 - 10) / 4
y = 30
<em>Liaqat's uncle is 30 years old. </em>
Answer:475
Step-by-step explanation:
118.75 is the cost whitch includes a 10$ service fee
118.75x10=475
How you start the equation is by plugging
3
into both of the
x
's in the problem to make it:
f
(
3
)
=
3
(
3
)
−
4
Next, you multiply the
3
(
3
)
to get
9
and subtract
4
. So in the end, you leave the
f
(
3
)
and
9
−
4 is
5
, so the
y
in the equation is
5
.
The answer would be written as
f
(
3
)
=
5
Answer:
-1 1/3
Step-by-step explanation:
To change and improper fraction (larger number in the numerator than the denominator) to a mixed number
divide the numerator by the denominator
4/3 =1 with 1 left over
Take the leftovers and put it over the denominator
1/3
The mixed number is 1 1/3
Since the number was negative, we put the negative out front
-1 1/3
