Below you will find the question is broken down into two parts. The first is asking you to solve equations and show your work. T
Schach [20]

Step-by-step explanation:

Equation (1) is :

x+2=5

Subtract 2 from both sides,

x+2-2=5-2

x=3

Equation (2) is :

2n+5=n

Taking like terms together,

2n-n=-5

n=-5

Equation (3) is :

5(x+2)-7=3x+5

⇒5x+10-7=3x+5

taking like terms together,

5x-3x=5-10+7

⇒2x=2

x=1

Hence, x =3, n = -5 and x = 1 is the required answer.

Please help me with number five write an inequality thank you :)
Igoryamba

Esecially the problem is 3x +x < 160

To find this out we first need to combine like terms

4x<160

Then get rid of the coefficient. In this problem, we divide by 4

x<40

So Rachel has to be less then 40, and Stephanie has to be less than 120.

rusak2 [61]

Answer:

6.4

Step-by-step explanation:

Find measurement of leg using pythagorean theorem  

b^2 = c^2- a^2

b^2= 13^2 - 4^2

b^2= 169-16

b^2= 153

b= 12.4

t+6= 12.4

subtract 6 from both sides

t= 6.4

Answer:

read the explanation, i'm not gonna answer this one for you, but instead I want you to try this on your own.

Step-by-step explanation:

divide the 360 by each percentage, and if you dont know how to do that, there are videos out there, i <em>would</em> explain it <em>but </em>i dont have much time to write all of that. after you get each number from dividing 360 by each percentage <em>individually </em>you will add up the <u>needed</u> numbers. that will give you your answer! have a nice day :D
