Phone’s plus charges a connection fee of 35 cents and 3 cents per minute. which equation could be used to determine the number of minutes, X, when a phone call would cost the same at both companies A 0.35 + 0.3 = 0.45 + 0.2x
B 0.35 + 0.3x= 0.45 + 0.02x
C 35 + 0.03 = 45 + 0.2x
D 35 + 0.03x = 45 + 0.02x

step-by-step explanation:

always plug in x. in this case, x equals 4.

i'm going to first solve 4(2+3x)

1) 4(2+3(4)) use pemdas to solve.

i'm going to multiply whats in the parenthesis first, so 3 times 4=12.

2)4 (2+12) i'm then going to multiply 4 by both numbers in the parenthesis (because multiplying comes before adding)

4 times 2= 8.   4 times 12= 48

4) (8+48)= 56 (answer)

i'm then going to solve 8+12x and plug in 4 for x.

1) 8 +12(4)

multiplying comes before adding, so i'm gonna multiply 12 and 4.

12 times 4= 48.

2) 8+48=56

both equal the same!

relating to or denoting a system of numbers and arithmetic based on the number ten, tenth parts, and powers of ten.

step-by-step explanation:

-22

times both sides by 2, times () by 8, add alile terms, move terms, add alike and caculate divide both sides by 3

the answer is 1/4
