Answer:
Step-by-step explanation:
let x = how many joe sold
let 4x = how many abe sold
900 = x + 4x
900 = 5x
180 = x
joe sold 180
and abe sold 4x
4(180) = 720
hat means Abe sold 720 trucks
finally, let's check our answer to make sure the total is 900
180 + 720 = 900
our answer is right
Tyler's $1,000 investment will be worth $1,240 after 6 years, invested at 4% interest rate.
The problem gives the following relevant data:
Principal = $1000
Interest rate = 4% simple interest
Term or time period = 6 years
Since simple interest is given, we need to use the simple interest formula;
I = P x R x T
where: P is the principal, R is the interest rate, and T is the time the money will be invested.
I = $1000 x 4% x 6yrs
I = $1000 x 0.04 x 6
I = 40 x 6
I = 240 ==> Interest earned after 6 years is $240.
Total Investment = Principal + Interest
T.I. = $1,000 + $240
T.I. = $1,240 ==> the value of Tyler's investment after 6 years.
Answer:
30 ounces
Step-by-step explanation:
You first have to write out the two equations:
5+0.25x=y
2+0.35x=y
Then simply equal the equations to each other:
5+0.25x=2+0.35x
Subtract the 2 from both sides:
3+0.25x=0.35x
Subtract the 0.25x from both sides:
3=0.10x
Divide the 0.10 on both sides:
30=x
So, 30 ounces is your answer!
You can check by plugging 30 back into the equations to make sure that they are equal to each other.
5+0.25(30)=12.5
2+0.35(30)=12.5
Number one is x=9,-9
number two is x=0
number three is x=12,-12
number four is 5i, -5i
A square has 2 pairs of parallel lines
