So the answer is C. There is no solution, because the equation is false
A and B choices both have the answer, the value of x.
D choice only when the equation is true like 2=2.
2x+8x=30. x= #of pens
10x=30. combine like terms
x=3. divide by 10 to isolate (get by itself) x
2(3)=6. the # of white pens are represented by 2x
6 white pens
hope this helped!
Answer:I am pretty sure you shade the right side on all but the second one you shade the left side.
Step-by-step explanation:
<span>1) Solve for x:
2x=12
divide both sides by 2
2x/2 = 12/2
x = 6
2) If x=10, what is x+2x+7?
</span>10 + 2(10) + 7 = 10 + 20 + 7 = 37
<span>3) A petting zoo always brings 5 goats to a birthday party. They also bring two chickens per guest. If there are 20 guests, how many animals in total will be brought?
</span>two chickens per guest and there are 20 guests
so 2 x 20 = 40 (40 chicken for 20 guests)
40 chicken + 5 goats = 45 animals
answer
45 animals in total
