Answer:

$46.20

Step-by-step explanation:

His earnings: 8.8*7 = 61.6

He gave away 1/4, so he has 3/4 left

3/4*61.6=46.2

Answer:

$46.2

Step-by-step explanation:

If kevin is paid $8.80 per hour and he worked 7 hours, we need to multiply the hourly pay by the number of hours worked:

$8.80(7) = $61.6

In total I earn the amount of $61.6.

He gave 1/4 of this earnings ti his mother.

1/4 of $61.6 is:

\frac{61.6}{4} =15.4

so he gave $15.4 to his mother.

what he has left is the subtraction of what he earned and what he gave his mother:

$61.6 - $15.4  = $46.2

He has $46.2 left

What is the product? (x 3)(2 x minus 1) 2 x squared minus 3 2 x squared 6 x 2 x squared 5 x minus 3 2 x squared 6 x minus 3.
prohojiy [21]

The product of the function is 2x^2+ 5x - 3

We are to find the product of the functions x + 3 and 2x -1

  • let f(x) = x+ 3
  • g(x) = 2x - 1

Taking the product:

f(x)g(x) = (x+3)(2x -1)

f(x)g(x) = x(2x) - x(1) + 3(2x) + 3(-1)

f(x)g(x) = 2x^2 - x + 6x - 3

f(x)g(x) = 2x^2+ 5x - 3

Hence the product of the function is 2x^2+ 5x - 3

There are 10 marbles in a bag. 1/5 are red and the others are blue. What is the ratio to blue marbles.
Irina-Kira [14]

Answer:

Ratio = 1 : 4

Step-by-step explanation:

Total marbles = 10

Given 1/5 is red, that is 1/5 of the total marbles are red

                                                            \frac{1}{5} \ of \ 10 = \frac{1}{5} \times 10 = 2

Therefore , 10 - 2 = 8 marbles are blue.

Ratio of red marbles to blue marbles

                                    \frac{2}{8} = \frac{1}{4} = 1 : 4

I need help i dont understand this,and j have and i have a big test coming up please help thanks
levacccp [35]
Since both of the angles are supplementary, you'd set the expressions up into an equation equal to 180(degrees).
So, your equation should look like:
                       22x + 4 + 35x + 5 = 180.
Next, you combine your like terms so that your next move will look like:
                       57x + 9 = 180.
Then you'd follow the subtraction and division property, so your next moves will look as the following:
                       57x + 9 - 9 = 180 - 9 equals 171
                       57x / 57 = 171 / 57 equals 3
So, finally, your answer is: x = 3.
