Answer:
C
Step-by-step explanation:
Remember PEMDAS
first add -3p^2 and 7p^2 to get 4p^2.
next add 8p^2 and 4p^2 to get 12p^2
12p^2 is your answer
Isolate the variable by dividing each side by the factor that don’t contain the variable.
Answer: t < -1
Answer:
c=5
Step-by-step explanation:
Simplify both sides of the equation.
4(6c+5)−2(3c−5)=120
(4)(6c)+(4)(5)+(−2)(3c)+(−2)(−5)=120(Distribute)
24c+20+−6c+10=120
(24c+−6c)+(20+10)=120(Combine Like Terms)
18c+30=120
Subtract 30 from both sides.
18c+30−30=120−30
18c=90
Divide both sides by 18.

c=5
hope this helps... :/
Step-by-step explanation:
For the point (5,8) to be a solution to the equations, when you insert x=5 and y=8 , they have to equal to the given values
substituting (5,8) into 4x+y
4(5)+8
=20+8
=28
substituting(5,8) into x-y=3
5-8
= -3
