5 is a constant. (it has no variables)
x + 2 is not a constant. It does, however, have two terms, x and 2.
(terms are seperated by addition/subtraction)
This rules out a and b.
As for c... 5(x+2) implies <em>multiplication</em>, which would be a product, not a sum.
d. The product of a constant factor 5 and a 2-term factor x+2
Answer:
B. divide both sides of the bottom equation by 2
Step-by-step explanation
If opposite means additive inverse, then none of the answers is correct
The given system of equations is
4x+2y=4
12x+y=22
The coefficient of y in the top equation is 2 and the coefficient of y in the bottom equation is 1.
One way to make the coefficient of y have opposite sign is to multiply the bottom equation by -2 to get:
4x+2y=4
-24x-2y=-44
Or we divide the top equation by -2
-2x-y=-2
12x+y=22
If opposite means, multiplicative inverse, then dividing through both sides of the bottom equation by 2 gives:
4x +2y=4
6x + ½y=11
Hence the second choice is correct.
Sunny made a paper cone to hold candy for favors for a baby shower after making the clone she measures the slant height of the cone and then the diameter of the base of the king measurements are shown in the picture below find the volume of the cone 3.5" 5 inches
If n stands for the smallest number, then the second and third number would be (n + 1) and (n + 2)
Write the equation based on what are given
the sum of three numbers = 72
n + (n + 1) + (n + 2) = 72
Then, solve the equation
n + (n + 1) + (n + 2) = 72
3n + 3 = 72
3n = 72 - 3
3n = 69
n = 69/3
n = 23
The smallest number is 23
