The sum of two numbers is thirty seven. Using x to represent the larger of two numbers, translate “the difference between nine m
just olya [345]

Two numbers = 37

Larger number is x, so the smaller number is 37 - x:

x + (37 - x) = 37

“The difference” is subtraction, so we are subtracting the smaller and larger number.

“Nine more than twice the larger number” looks like 9 + 2x, and “the sum of the smaller number and three” looks like (37 - x) + 3. Because this is subtraction, we would write (9 + 2x) - (37 - x) + 3. First, distribute the negative sign:

-(37 - x) = -37 + x

We then simplify:

9 + 2x - 37 + x + 3 (subtract 3)

9 + 2x - 34 + x

-25 + 2x + x (subtract 8 and 34 then add 2x and x)

-25 + 3x

2. A chemist has a 25% and a 50% acid solution. How
AnnZ [28]

Answer:

x is mL of 25% acid and y is mL of 50% acid

We set up 2 equations:

A) x + y = 250

B) .25 x + .50y = .35 * 250 which equals

B) .25x + .50y = 87.50  Multiplying A) by -.5

A) -.5x -.5y = -125  adding the equations we get

-.25x = -37.50

x = 150 mL

y = 100 mL
