Pete traveled 1,380 miles in two days. the first day , he traveled 1.5 times as far as he did the second day . how many miles did he drive on the first day

a.828
b.552
c.920
d.460

A

Step-by-step explanation:

Let distance travelled on first day be and distance travelled on second day be , so we can write:

[since in 2 days he travelled a total of 1380 miles]

Also, since first day he travelled 1.5 times second day, we can write:

Substituting this into first equation and solving for , we get:

We want to know how many miles he drove on first day, which is 1.5 times this, so we have:

miles

Answer choice A is correct.

x=4

step-by-step explanation:

answer: the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.

step-by-step explanation:

the given rate of interest i= 85%

in calculating the monthly payment for a loan with an interest rate compounded monthly, the value of the interest rate per period we use in the formula must be in decimal form.

to convert it in decimal, we divide it by 100, we get

hence, the value should be used for i in the formula of calculation the monthly payment , the interest rate per period is 0.85.
