Its C because both 5x and 2x have the same x at the end and their both considered like terms. so the answer would be C and if it was to be solved 5x+2x= 7x and 7+7x would be the final answer. since the 7 with no x has no x, it wouldnt have to be solved or simplified
Answer:
x=1.818minutes
Step-by-step explanation:
3/60 miles per minute for walk
8/60 miles per minute for run
0.05x + 0.1333y=1
x+y=10
x=y-10
0.05(y-10) + 0.133333y = 1
0.05y-0.5+0.133333y=1
0.18333y=1.5
y=8.18minutes
x=10-8.18
x=1.818minutes
You have a lot of questions here, I can help you with a few of them.
When you simplify the polynomials, you put together all of the terms that have the same degree. That means the variables have the same exponents. The number of terms are the items separated by plus and minus signs.
Here are the answers for the first three:
1)
2)
3)
Answer:
E. 14x + 14
Step-by-step explanation:
4(3x + 2) + 2(x + 3) (distribute 4 to 3x and 2)
12x + 8 + 2(x + 3) (distribute 2 to the x and 3)
12x + 8 + 2x + 6 (collect like terms)
14x + 14
Hope this helps ya!!
Step-by-step explanation:
The equation has 100, which represents the cost of the printer, then you add to .05p which stands for each page is .05 and you multiply it by p which would be the amount of pages, so when you do .05p it stands for the equation to to calculate the total cost of pages. Then .25p is the cost times the amount of pages.
Hope this helps, you understand it more.
