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.
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.

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
