5x+2=3x-20-1x
add like terms
5x+2=(3-1)x-20
5x+2=2x-20
subtract 2x from both sdies
5x-2x+2=2x-2x-20
3x+2=0-20
subtract 2 from both sides
3x+2-2=-20-2
3x=-22
divide both sides by 3
x=-22/3 or -7 and 1/3

Which is the correct input-output table for the function g(x)=-1/2(4x+6)
Sonbull [250]

Answer: The third choice.

Step-by-step explanation: To find the first output, start with your first input. In this case, it's -2, so your equation would be g(-2)= -1/2(4(-2)+6). Start by solving inside the parenthesis. 4x-2=-8 and -8+6=-2. -1/2x-2= 1, so your first output should be 1. The only choice that has this is the third one, so that is your answer. Hope I could help :)

Anthony has two ribbons. One is 12 inches long and the other is 20 inches long. He wants to cut the ribbons into smaller strips
liraira [26]

Answer:

4 inches.

Step-by-step explanation:

Length of first ribbon =12 inches.

Length of second ribbon =20 inches.

To find the greatest length he can make of smaller strips that are all equal in length, we need to find the H.C.F of the two numbers.

12=2\times 2\times 3

20=2\times 2\times 5

For H.C.F, we will take the product of all the common factors in the prime factorization of the two numbers.

H.C.F =2\times 2=4

So, he can cut three 4 inches ribbons from the 12 inches ribbon and five 4 inches ribbons from the 20 inches ribbon.

Hence, the greatest length he can make of smaller strips that are all equal in length is 4 inches.
