You get 130 because the formula for a triangle is A=bh/2. you multiply 20 and 13 then divide it by 2 and get your answer
The correct answer is A. The number of dimes (d) and quarters (q) is 22, as said in the problem. So d + q = 22. We know that the total value of these dimes and quarters is $3.40 or 340 cents. We also know that dimes are worth 10 cents and quarters worth 25 cents. The total number of dimes and quarters would be represented like this: 10d + 25q = 340. Therefore A. is the correct answer.
Answer:
4.5 It doesn't come out evenly, but cross products do work.
Step-by-step explanation:
She is not correct.
50 * x = 3 * 75 Combine the right
50x = 225 Divide by 50
x = 225/50
x = 4.5
Answer:
The last answer choice is correct, I am pretty sure.
Just go on the calculator (like Desmos) and just use the decimals to determine which one is true.
