Answer is D.
28:44 is the ratio but you have to simplify it. Divide both by 4. 28 divided by 4 = 7; 44 divided by 4 = 11
Answer:
x = 44 and y = 4
Step-by-step explanation:
Given:
x - y = 40
2x + 3y = 100
Isolate for x in the first equation:
x = 40 + y
Sub x = 40 + y into the second equation and solve for y:
2(40 + y) + 3y = 100
80 + 2y + 3y = 100
5y = 20
y = 4
Sub y = 4 into the equation for x:
x = 40 + 4
x = 44
Therefore, x = 44 and y = 4
To find the intersection<span> of these </span>two sets<span>, we need to find out what elements they have in common. The numbers 3, 4, 5 are elements of both </span>sets, therefore theintersections<span> of A and B is {3. 4. 5].</span>
