combining like terms in a polynomial is adding or subtracting together terms that have the same degree in the exponents.
example. 3x^3 + 5x^6 + 2x^3 +7x + 9x^6
= 7x + 5x^3 + 14x^6
Answer:
10 in., 18.5 in., 31.5 in.
Step-by-step explanation:
Ask me if you need step-by-step, since the problem seems to be multiple choice.
First, lets do all calculations in kg. 1kg=1000 grams
Lets set 1 cat's mass as x.
Lets set the other cat's mass as y.
1) x+y=11
2) y=x+1.5
Lets plug eq 2 into eq 1.
x+x+1.5=11
2x+1.5=11
2x=9.5
x=4.75 kg
If one cat weighs 4.75 kg, then the other must weigh 6.25 kg.
Answer:
Tim's Cost of the box of candy: 7$ for one box
Tim's Cost for the peanuts: $5 for one box
Kevin's Cost for the candy is: $8 for one box
Kevin's Cost for the peanuts are: $5 for one box
Step-by-step explanation:
Tim:
7x16=112
5x4=20
112+20=132
Kevin:
20x8= 160
5x 6=30
160+30 =190
Answer:
x = 30
Step-by-step explanation:
They are vertical angles.
Equation: 2x - 15 = 45
2x = 60
x = 30
