The problem is already in terms of c.
ax+bx/3=c

ax+bx=3c
x(a+b)=3c
a+b=3c/x
a=3c/x +b or b=3c/x -a

grigory [225]

Answer:

a) $4000

b) $2000

Step-by-step explanation:

a)

interest = Principal x rate as decimal x time

interest = 20,000 x 0.05 x 4

interest = 4000

b)

interest = Principal x rate as decimal x time

interest = 20,000 x 0.05 x 2

interest = 2000

you save $2000 if you pay after 2 years

During second period, Kiera completed a grammar worksheet. Of the 90 questions, she got 70% right. How many questions did Kiera
ANEK [815]

Answer:

we conclude that Kiera got the right 63 questions.

Step-by-step explanation:

Total questions = 90

The percentage of correct question = 70%

Using the formula

The number of correct questions = 70% of 90

                                                         = [70/100] × 90

                                                          = 0.7 × 90

                                                           = 63

Therefore, we conclude that Kiera got the right 63 questions.

I need help! PLEASE HELPP PLEASE HELP!!!
DanielleElmas [232]

Answer:

Part 1: 31x+25=180

part 2: x=5

Step-by-step explanation:

there are 180° on a straight line, which is the base/ bottom line of the traingle (indicated by the arrow on the end).

so, 180-151= 29

29° is the third angle on the traingle.

now, there are 180° in a triangle, therefore to find an equation for x:

29+20x-3+11x-1= 180 (adding up all the angles and making it equal to 180°)

now simplify this equation to get:

31x+25=180 (PART 1)

to find x simply solve the equation:

31x=180-25

31x= 155

x= 155/31

x=5 (PART 2)

Adam put $100 in a savings account. After 10 years, he had $1649 in the
Leno4ka [110]

Step-by-step explanation:

hihi, so this is a classic interest rate problem. It's not too bad if you know your properties of e and ln. After establishing the base equation you can divide by 100 then take the natural log of both sides to "get rid" of the e and finally end it by dividing by 10 to isolate r.
