What is 2/3 (x+13)=22

Answers

Answer 1
Answer: X is 20, as 33 * .66 is 22.
Answer 2
Answer: 2/3(x+13)=22
2/3x + 26/3 = 22
2/3x = 4/3
x = 4/3 * 3/2 = 12/6 = 2
x = 2

Answers

$1.6, 20% of $8 ($6.5+$1.5) is $1.6

Answer:

.30

Step-by-step explanation:

6.50+1.50+20%=8.30

6.50+1.50=8

8+.3=8.30

so 6.50+1.50+.30=8.30

For this case, we must simplify the following expression:

\sqrt [3] {\frac {4x} {5}}

For this, we follow the steps below:

We rewrite the expression as:

\frac {\sqrt [3] {4x}} {\sqrt [3] {5}}

We multiply by:

\frac {(\sqrt [3] {5}) ^ 2} {(\sqrt [3] {5}) ^ 2}\n\frac {\sqrt [3] {4x}} {\sqrt [3] {5}} * \frac {(\sqrt [3] {5}) ^ 2} {(\sqrt [3] {5}) ^ 2} =

We have by definition of multiplication of powers of equal base that:

a ^ m * a ^ n = a ^ {m + n}

So:

\n\frac {\sqrt [3] {4x} * (\sqrt [3] {5}) ^ 2} {\sqrt [3] {5}) ^ 3} =\n\frac {\sqrt [3] {4x} * (\sqrt [3] {5}) ^ 2} {5} =

We know that:

(\sqrt [3] {5}) ^ 2 = \sqrt [3] {5 ^ 2}

So, we have:

\frac {\sqrt [3] {4x} * \sqrt [3] {5 ^ 2}} {5} =\n\frac {\sqrt [3] {4x} * \sqrt [3] {25}} {5} =\n\frac {\sqrt [3] {100x}} {5}

The rectangle has an area of 4(x+3) square units.A- If the dimensions of the rectangle are doubled, what is the area of the new rectangle in terms of x? Show your work.


B- Will the ratio of the area of the original rectangle to the area of the larger rectangle be the same for any positive value of x? Explain.

Answers

Suppose there is a rectangle with a width and length of x and y. The area would be xy.

A rectangle with width and length 2x and 2y would have an area of 4xy.

In essence, when you multiply the lengths by 2, the area multiplies by 2 SQUARED.

4(4(x+3)) = 16(x+3).

The ratio will be the same for any value of x because the area is still being multiplied by the same 2².
