For this case we must find the value of "x" of the following linear equation:

$4x + 8 = 88$

We subtract 8 on both sides of the equation:

$4x = 88-8\\4x = 80$

We divide between 4 on both sides of the equation:

$\frac {4x} {4} = \frac {80} {4}\\x = 20$

So, the value of x is 20

Answer:

$x = 20$

Answer:

X= 20

Step-by-step explanation:

4x + 8 = 88

4x +8 - 8 = 88 - 8

4x = 80

4x/4 = 80/4

X = 20

use the slope formula to calculate the slope of the line that contains the two points (-4,0) and (5,2)

Solnce55 [7]

Answer:

$\frac{2}{9} x$

Step-by-step explanation:

To find slope using two points you need to find the difference in x and y. You use $\frac{y_{2}-y_{1}}{x_{2}-x_{1} }$

So, 2-0=2 and 5-(-4)=9. Therefore the slope is 2/9x

Find the area of this trapezoid. Include the correct unit in your answer.

NemiM [27]

Answer:

$\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}$

Step-by-step explanation:

we are given a trapezoid

we want to figure out the area

remember that,

$\displaystyle A _{ \text{trapezoid}} = \frac{a + b}{2} h$

where a and b represent the parallel lines and h represents the height

we get from the pic that a and b are 5 and 15 respectively and h is 7

so substitute:

$\displaystyle A _{ \text{trapezoid}} = \frac{5 + 15}{2} \times 7$

simplify addition:

$\displaystyle A _{ \text{trapezoid}} = \frac{20}{2} \times 7$

simplify division:

$\displaystyle A _{ \text{trapezoid}} = 10\times 7$

simplify multiplication:

$\displaystyle A _{ \text{trapezoid}} = 70$

since we multiply two same units we of course have to use square unit

hence,

$\displaystyle A _{ \text{trapezoid}} = 70 {m}^{2}$

A bicycle wheel with the diameter 70cm is making 25 revolutions while travelling. Find the distance covered by the bicycle

Diano4ka-milaya [45]

Answer: 5500cm.

Step-by-step explanation:

A revolution corresponds to circumference of the bicycle wheel.

The radius of the circle = 70/2 since two radii makes a diameter.

Therefore r = 35cm

Circumference of a circle = 2πr or πd where π = 3.142 or 22/7

We now have = 2 x 22/7 x 35

Therefore 0ne revolution = 220cm.

Therefore, the distance traveled by making 25 revolution

= 220 x 25

= 22000/4

= 5500cm.
