Answer:

x=42.5

Step-by-step explanation:

First, start by setting up the equation

these are both same side interior angles, so they both add up to 180

(3x+10) + x = 180

4x+10 =180

subtract both sides by 10

-10 -10

4x=170

divide both sides by 4

x=42.5

snow_tiger [21]

Answer:

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

Step-by-step explanation:

Given : A potato launched by a particular potato gun has a height described by $h ( t ) =-16 t^2+124 t+4$ .

To find : When is the potato 224 feet in the air?

Solution :

When the potato is 224 feet in the air i.e. $h(t)=224$

Substitute in the equation $h ( t ) =-16 t^2+124 t+4$ ,

$224=-16 t^2+124 t+4$

$16t^2-124 t+220=0$

$4t^2-31t+55=0$

Applying quadratic formula, $x=\frac{-b\pm\sqrt{b^2-4ac}}{2a}$

Here, a=4, b=-31 and c=55

$t=\frac{-(-31)\pm\sqrt{(-31)^2-4(4)(55)}}{2(4)}$

$t=\frac{31\pm\sqrt{81}}{8}$

$t=\frac{31\pm9}{8}$

$t=\frac{31+9}{8},\frac{31-9}{8}$

$t=5,2.75$

The potato is 224 feet in the air after 2.75 second on the way up and after 5 seconds on the way back down.

7 − 58z = −23 ASPA A. 9.38 B. 48 C. −24 D. 24

Hitman42 [59]

Answer:

the given are not correct the real answer is 15/29 or 0.517...

Step-by-step explanation:

7-58z = -23

-58z = -23 -7

-58z =-30 the negatives will cancel each other out

-58. -58

z = 30/58 divide both by 2

z= 15/29 which can also be equal to 0.517...

Please find the value of x, show work if possible: m=10x−x

Elanso [62]

m = 10x - x

Combine like terms.

m = 9x

Divide both sides by 9.

x = m/9
