Answer:

$x = 1$

step By Step Explanations:

1) Remove parentheses.

$13 - 2x - 2 = 2(x + 2) + 3x$

2) Simplify 13 - 2x - 2 to -2x + 11.

$- 2x + 11 = 2(x + 2) + 3x$

3) Expand.

$- 2x + 11 = 2x + 4 + 3x$

4) Simplify 2x + 4 + 3x to 5x + 4.

$- 2x + 11 = 5x + 4$

5) Add 2x to both sides.

$11 = 5x + 4 + 2x$

6) Simplify 5x + 4 + 2x to 7x + 4.

$11 = 7x + 4$

7) Subtract 4 from both sides.

$11 - 4 = 7x$

8) Simplify 11 - 4 to 7.

$7 = 7x$

9) Divide both sides by 7.

$1 = x$

10) Switch sides.

$x = 1$

Therefor, the answer is x = 1.

Each Saturday morning, Beau practices throwing pitches to his dad. His dad estimates the probability of each pitch Beau throws b

guajiro [1.7K]

Answer: 0.27

Step-by-step explanation:

Given that :

Probability of being a strike ; p(strike) = 0.3

Note : the probability of each pitch Beau is independent :

Probability that next three will be a strike :

p(strike) * p(strike) * p(strike)

= 0.3 * 0.3 * 0.3

= 0.27

Using the number line shown, subtract 1 2/6 from 4 4/6.

Soloha48 [4]

Hey there!

$\bold{1\frac{2}{6}-4\frac{4}{6}}$

$\bold{1\frac{2}{6}=1\frac{1}{3}=\frac{4}{3}}$
$\bold{4\frac{4}{6}=4\frac{2}{3}=\frac{14}{3}}$
Problem becomes: $\bold{\frac{4}{3}-\frac{14}{3}}$
To solve our new problem $\uparrow;\downarrow$
$\bold{4-14=-10}$
The $\bold{3's}$ stay the same because the same
$\bold{\rightarrow=\frac{-10}{3}}$
$\boxed{\boxed{\bold{Answer:\frac{-10}{3} (or)=-3\frac{1}{3}}}}$

Good luck on your assignment and enjoy your day!

Can someone pls help ASAP

Vera_Pavlovna [14]

Answer:

89.44

Step-by-step explanation:

using the Pythagorean Theorem: $a^{2} +b^{2}=c^{2}$

$80^{2} +b^{2} =120^{2} \\6400+b^{2} =14400\\b^{2} = 8000\\b = 40\sqrt{5}$

120 is the hypotenuse so it would be c in the equation.

To solve, I simplified and isolated the variable. I got the square root of 8000 simplified (but idk how to write that out lol)

This answer is closest to 89.44
