Replace the f(x) in the second equation will 6x + 5 so then it looks like 2(6x + 5) + 6. Then distribute so it’s 12x + 10 + 6 and then simplify to 12x + 16

Pedro withdrew some money from his bank account. After giving $15 to his cousin, he spent 1/5 of what was left on a lamp, then h
kolezko [41]

Answer:

He gave 8.57 % of his money for his cousin.

Step-by-step explanation:

In order to calculate the percent that Pedro gave to his cousin, we first need to calculate his total amount, which is given by "x". This is given by:

x = 15 + (x - 15)/5 + 128

x = 15 + x/5 - 3 + 128

x = x/5 + 140

x - x/5 = 140

(5*x - x)/5 = 140

4*x = 700

x = 175

He had originally $175 and gave $15 to his cousing, therefore we can use a rule of three to calculate the percent that he gave to his cousin:

$175 -> 100%

$15 -> y%

175*y = 1500

y = 1500 / 175

y = 8.57 %

Find the value of x in given right triangle
Novay_Z [31]

Step-by-step explanation:

It is a right angled triangle so with reference angle 37°

hypotenuse (b) = 10

perpendicular (p) = x

So

tan 37° = p/ b

0.75 = x / 10

x= 0.75/10

Therefore x = 0.075

Hope it will help you :)

Given the pay rate and hours worked(8.50, 38.0) determine the gross earnings, Federal taxes (assuming 15% of gross earnings), st
gayaneshka [121]
$8.50 x 38 = $323
$323 x .15 = $48.45
$323 x .05= $16.15
$323 x .02 = $6.46
$323 x .0765= $24.71

$48.45 + $16.15 + $6.46 + $24.71= $95.77 deductions

$323 - $95.77 = $227.23 net pay
