DanielleElmas [232]

Answer:

Mr. Martin drove 415 miles this week.

Step-by-step explanation:

The question says Mr. Martin drove 125 miles more than <u>last week</u>. How many miles did Mr. Martin drive this week?

How many miles did he drive last week?

Remember: 290 miles is the miles he drove last week.

The problem says he drove 125 miles AND 290 miles this week. So you take the SUM of them to see how many miles he drove together.

290 + 125 = 415

Dwight deposits $150 into his new savings account. The account earns 5% interest compounded annually.
GrogVix [38]

Answer:

A=\$150(1.05)^{t}  

Step-by-step explanation:

we know that    

The compound interest formula for this problem is equal to  

A=P(1+r)^{t}  

where  

A is the Final Investment Value  

P is the Principal amount of money to be invested  

r is the rate of interest  in decimal

t is Number of Time Periods  in years

in this problem we have  

P=\$150\\ r=5\%=0.05  

substitute in the formula above  

A=\$150(1+0.05)^{t}  

A=\$150(1.05)^{t}

2. Solve the system of equations using the substitution method.
Dimas [21]

Answer:

x = 1

Step-by-step explanation:

2x + 3y = 20

2x + 3(10-4x) = 20

2x + 30 - 12x = 20

combine like terms

-10x + 30 =  20

        -30      -30

-10x = -10

divide both sides by -10

x = 1

Hope this Helps!!!
