Which of the following is the solution to [x+11k 17 ?
A. X< 6 and x < -28
B. X< 6 and xx -28
O
c. x<6
D. X< 6 orx > -28

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.

you can first factor out the n to get n(1+5). we know that 1+5 is 6, so we just have 6n.
