Answer:

x = 5

Step-by-step explanation:

We have the algebraic expression and are asked to solve for x.

To solve, we need to isolate x.

2x + 22 = 4(x + 3)

Distribute :

2x + 22 = (4(x) + 4(3))

2x + 22 = 4x + 12

Subtract 12 from both sides :

2x + 10 = 4x

4x = 2x + 10

Subtract 2x from both sides :

2x = 10

Divide 2 from both sides to get x alone :

x = 5

What is the slope intercept form of 10x + 2y =8

antoniya [11.8K]

Slope intercept form is: y = mx + b

Isolate the y. First subtract 10x from both sides

10x (-10x) + 2y = 8 (-10x)

2y = -10x + 8

Isolate the y. Divide 2 from both sides and <em>all</em> terms.

(2y)/2 = (-10x + 8)/2

y = -5x + 4

y = -5x + 4 is your slope intercept form answer.

hope this helps

If the original quantity is 10 and the new quantity is 11, what is the percent crease?

LenKa [72]

Answer:

10 %

Step-by-step explanation:

We first find change in the quantities

Then we write the change in quantity on original quantity and multiply by 100%

This implies that,

$\frac{11 - 10}{10} \times 100\%$

$=\frac{1}{10}\times100\%$

$=10\%$

Therefore the percentage increase is 10%

Round 132,654 to the nearest one thousand

grin007 [14]

Well the 2 is in the thousands and the number before it is six and because of the number before 2 happens to be over 5 the 2 changes into a 3 thus making your answer 133,000
