Mathematics
1 answer:
natali 33 [55]2 years ago
6 0

Answer:

17

Step-by-step explanation:

The sentences 'Spencer is 32 years younger than Jennifer' can be modeled by x = y-32 (x representing spencer's age and y representing Jennifer's). The sentence '3 years ago, Jennifer's age was 3 times Spencer's age' can be modeled by the equation x-3 = 1/3(y-3). Solving the second equation for y gives you y = 3x-6. Substitute into the first equation to get x = (3x - 6) - 32. Solve for x, which represents Spencer's age, to get x = 17

A chemist mixes a 10% hydrogen peroxide solution with a 25% hydrogen peroxide solution to create 30 liters of a 15% hydrogen per
FromTheMoon [43]
Your two equations are at the top, in the box is what each variable represents. Below the box is total liters of the 15%, which is going to equal the total liters for 10% plus the total liters for 25%. Make your percentages into decimals. There’s a total of 30 liters so, x+y needs to equal 30. Isolate a variable, I chose y, you can do either or (isolating x would be more math). Y is going to equal 30-x, substitute that for the Y in the second equation, then you need to distribute 0.25 into 30-x. Then it’s simple math, subtract 7.50 from both sides, add like gets, divide both sides by -0.15, making x=20.

The area of a square postcard is 25 square inches. How long is each side postcard?​
ivolga24 [154]

Answer:

5 inches

Step-by-step explanation:

To find the area of a square the formula is A = bh which with a square is essentially one side squared. We know this because every side of a square is the same. We also know that 5 squared is 25 meaning the answer is 5 inches(You could also use the formula A = bh : A = 5 x 5 : A = 25).
