The difference of two numbers is 8. When twice the first number is added to three times the second number, the result is 51. What are the two numbers?
OA.
12 and 4
ОВ.
15 and 7
Ос.
20 and 12
OD
23 and 15

b. 2

step-by-step explanation:

the slope of a line =δy/δx

δy= y₂-y₁

δx= x₂-x₁

therefore, using the points (-2,-3)   and (3,7) we can calculate gradient as follows:

m=(7--3)/(3--2) (a number minus a negative number the sign changes to a plus)

m=(7+10)/(3+2)

=10/5

=2

if you explain the the question more correctly i might be able to answer this better

step-by-step explanation:

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.
