Justin is 2 years older than one third marcella's age

Answers

Answer 1

Answer: $x=63$ which is Marcella's age

$(1)/(3)$ of 63 is 21 ⇔ 63÷3=21

$2+21=23$ which is Justins age

$2(23)-4=42$

Marcella's age⇒63

Justin's age⇒23

Aimee's age⇒42

Note: I was trying to find a better way to do this but I couldn't figure it out in the top of my head so I'm sorry for the long response

Answer 2

Answer:

If Marcella is 63, divide by 3 is 21, add 2 equals out to be 23 which is Justin's age. Then 23 multiplied by 2 is 46, subtract 4 from 46, which equals out be 42 and that is Aimee's age.:)

Marcella= 63
Justin= 23
Aimee= 42

Abigail has $30.00 to buy groceries. She needs to buy some apples, some bananas, and 3 pounds of potatoes. Fuji apples are $1.79 a pound, bananas are $0.36 each, and potatoes are $2.99 for a 3 lb. bag. If a represents the number of pounds of apples Abigail buys and b represents the number of bananas she buys, which expression represents the amount of change she receives after her purchases?

Answers

The expression that best describes her change may be found by constructing the mathematical equation that describes the situation.

Since a represents the number of apples, b represents the number of bananas, we let c represent her change. Hence,

30=1.79a+0.36b+2.99+c

rearranging the terms to solve for c,

c=30-2.99-1.79a-0.36b
c=-1.17a-0.36b+27.01

THE ANSWER TO THE QUESTION IS C

I DO NOT KNOW THE EXACT STEPS BUT I DO KNOW THAT THE ANSWER IS C BECAUSE I JUST TOOK THE TEST AND IT SAID THAT THE ANSWER WAS RIGHT AND THEN IT HELPED ME PASS THE TEST

a man invested a total of $3,000 in two investments. he made a profit of 3% on the first investment and 4% on the second investment. if his total profit was $107, what was the amount of each investment?

Answers

Let the first investment be x
and second be 3000-x

so 3%of x + 4% of (3000-x) = 107
By solving x = 1300

First investment is 1300
second investment is 1700
