50 points decreased by 26%

RoseWind [281]

Get the decimal version of 26% by moving the decimal (at the end) over to spots, giving you .26. Multiply 50 by this, and you get .26*50=13. : )

Kate borrowed $400 from her friend. She will repay this amount plus 3 percent simple interest after one year. What is the total

tekilochka [14]

The answer is $412.

Let's first calculate simple interest. Simple interest (I) can be expressed as:
I = P * r * t
P - principal
r - rate
t - time period

It is given:
I = ?
P = $400
r = 3% = 0.03
t = 1 year

Therefore:
I = P * r * t = 400 * 0.03 * 1 = 12

The total amount Kate will repay is the principal amount (P) plus 3% simple interest (I):
P + I = 400 + 12 = $412

Solve the system of equations. −9y+4x−20=0−7y+16x−80=0\begin{aligned} &-9y+4x - 20=0 \\\\ &-7y+16x-80=0 \end{aligned}

gulaghasi [49]

Answer:

(x, y) = (5, 0)

Step-by-step explanation:

$\begin{aligned} &-9y+4x - 20=0 \\ &-7y+16x-80=0 \end{aligned}$

Subtract 4 times the first equation from the second:

(-7y +16x -80) -4(-9y +4x -20) = (0) -4(0)

29y = 0 . . . . . simplify

y = 0 . . . . . . . .divide by 29

4x -20 = 0 . . . . substitute 0 for y in the first equation

x -5 = 0 . . . . . .divide by 4

x = 5 . . . . . . . . add 5

The solution to this system is (x, y) = (5, 0).
