Must include an explanation !!<br><br> solve for x

Ira Lisetskai [31]

Answer:

x=5

Step-by-step explanation:

Volume of a rectangular prism= $\frac{1}{2}$ b x l x h

Set up you equation

120= $\frac{1}{2}$ (4 x 12 x $x$ )

Multiply inside the parentheses

120= $\frac{1}{2}$ (48x)

Multiply by $\frac{1}{2}$

120=24x

Divide by 24 on both sides

5=x

Check you answer

Volume of a rectangular prism= $\frac{1}{2}$ b x l x h

Set up your equation

$\frac{1}{2}$ (12 x 5 x 4)

Multiply inside the parentheses

$\frac{1}{2}$ (240)

Multiply by $\frac{1}{2}$

V=120yd³

Can anybody please help me out with this question I would really appreciate it so much. Please and thank you .

(7x+2)° = (9x–8)°

=>7x –9x = –8–2

=> –2x = –10

=> x = 10/2

=> x = 5

<ADB = (7x+2)°

= 7×5+2

= 37°

<BDC = (9x–8)°

= 9×5–8

= 45 –8

= 37°

<ADC = 37° + 37°

= 74°

What is the slope of the line that contains the points (-2,2) and (3,4)

malfutka [58]

<u><em>Answer: B. 2/5 *The answer must have a fraction.</em></u>

Explanation:

Slope-intercept form: → $y=mx+b$

m: represents the slope and is constant.

b: represents the y-intercept.

Used rise/run.

$\frac{rise}{run}$

$x^1,y^1=(-2,2)$

$x^2,y^2=(3,4)$

You had to find the slope by using formula.

$Slope=\frac{y^2-y^1}{x^2-x^1}$

$\frac{4-2}{3-(-2)}$

subtract by the numbers and add the numbers too.

$\frac{4-2=2}{3-(-2)=3+2=5}$

$=\frac{2}{5}$

Hope this helps!
