Hello.

In 10 years, his age will be

$\mathrm{z+10}$

The sum of his current age and 10 equals his age in 10 years.

2 years ago his age was

$\mathrm{z-2}$

The difference of his current age and 2 equals his age 2 years ago.

7 years ago his age was

$\mathrm{z-7}$

The difference of his current age and 7 equals his age 7 years ago.

Therefore, his age after 10 years will be $\mathrm{z+10}$ , his age 2 years ago was $\mathrm{z-2}$ , and his age 7 years ago was $\mathrm{z-7}$

I hope it helps.

Have a nice day.

NEED HELP The value of x is <br> .

The sum of all exterior angles of ANY polygon is equal to 360 degrees.

SO in this figure...
360 = 134 + 130 + x
360 = 264 + x
x = 360 - 264 = 96 degrees

Answer:

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

Step-by-step explanation:

The expression to simplify in this problem is

$7\sqrt[4]{80pq^2r^8}$

Which can be rewritten as

$7(80pq^2r^8)^{\frac{1}{4}}$

Or also as

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot (q^2)^{\frac{1}{4}} \cdot (r^8)^{\frac{1}{4}}$

Now we can apply the following rule for the calculation of the power of a power:

$(a^m)^n = a^{m\cdot n}$

So we get:

$7\cdot 80^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

Which can therefore be rewritten as

$7\cdot (2^4\cdot 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

And so, we get

$7\cdot 2 \cdot ( 5)^{\frac{1}{4}} \cdot p^{\frac{1}{4}} \cdot q^{\frac{1}{2}} \cdot r^{2}$

which can be finally rewritten as

$14 ( 5)^{\frac{1}{4}} p^{\frac{1}{4}} q^{\frac{1}{2}} r^{2}$

Maria drives to school in 20 minutes. She drives home in 24 minutes. What was her average driving speed in terms of d, the dista

max2010maxim [7]

Speed is distance/time so

[(d/20)+(d/24)]/2= 24d+20d/24•20•2=44d/20•24•2=22d/20•24=11d/240
