Answer:

Your answer would be 1/2

Step-by-step explanation:

We want to write and solve a system of equations to see how much each person earns.

What each one earned is:

Let's define:

The information is:

"Janet worked 3 hours more than David and 7 hours less than Kate"

From this we can write:

J = D + 3

J = K - 7

We know that:

Finally, we know that Kate earned $27 more than David an Janet combined, then we can write:

$9*K = $27 + ($7.50)*D + $6*J

Then we have a system of equations:

J = D + 3

J = K - 7

$9*K = $27 + ($7.50)*D + $6*J

We can rewrite the first and second equations to get:

D = J - 3

K = J + 7

Now we can replace these two in the other equation to get:

$9*(J + 7) = $27 + ($7.50)*(J - 3)+ $6*J

Now we can solve this for J:

$9*J + $63 = $27 + $7.50*J - $22.50 + $6*J

$9*J - $7.50*J - $6*J = $27 - $63 - $22.50

-$4.50*J = -$58.60

J = (-$58.60)/(-$4.50) = 13

This means that Janet worked for 13 hours.

And with:

K = J + 7 = 13 + 7 = 20

D = J - 3 = 13 - 3 = 10

We can see that Kate worked for 20 hours and David for 10 hours.

Then each one of them earned:

Janet = 13*$6 = $78

Kate = 20*$9 = $180

David = 10*$7.50 = $75

68 miles per hour.

Simply divide the total number of miles by the time it took in a decimal format.

6 1/4 hours=6.25

425/6.25=68

Answer:

Parallel line, [tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]

Perpendicular line, [tex]y=4-\frac{2x}{3}[/tex]

Step-by-step explanation:

For the parallel line, In the equation y=mx+c, we are trying to find c.

We know that m=[tex]\frac{3}{2}[/tex], so

we have the equation y=[tex]\frac{3x}{2} +c[/tex]

So we substitute the points we are given (3,2) into

[tex]2=\frac{3}{2}*3+c\\Thus, c= \frac{-5}{2}[/tex]

The final equation we get is

[tex]y=\frac{3x}{2} -\frac{5}{2}[/tex]

For the perpendicular line, we need to find the inverse of the slope.

The inverse of the slope [tex]\frac{3}{2} = -\frac{2}{3}[/tex]

So, we use this in our formula and also plug in the same coordinates we were given.

Therefore, we get:

[tex]2= -\frac{2}{3}*3+a\\a=4\\\\y=4-\frac{2x}{3}[/tex]

Answer:

∠ 1,3,5,7 = 32°

∠2,4,6,8,= 148°

Step-by-step explanation:

From the figure attached,

AB and CD are two parallel lines and another transverse line is intersecting these line at two distinct points.

Since, m∠1 = 32°,

∠1 and ∠4 are supplementary angles [Linear pair of angles]

m∠1 + m∠4 = 180°

32° + m∠4 = 180°

m∠4 = 180° - 32°

m∠4 = 148°

therefore,

m∠1,3,5,7 = 32°

m∠2,4,6,8,= 148°

Hello there! :)

The Distributive property states:

a(b+c)=ab+ac

So, we know what a is. It's 5.

b=3

c=0.4

5(3+0.4)

5*3+5*0.4

15+0.2

15.2

Step-by-step explanation:

Answer:

I got x <= 8/7 which is none of the answer options given. Ask your professor about that.

Step-by-step explanation:

7x-1 <= 7

add 1 on each side

7x <= 8

Divide by 7 on both sides

7x/7 <= 8/7

Final answer

x <= 8/7

Answer:

Option #1, 3 and 4

Step-by-step explanation:

7x - 1 <= 7

Let's try them one by one:

1)

x <= -1

-7 - 1 = -8 is less than or equal to 7: True

There could be multiple answers, so let's do the other ones:

2)

x <= 4

28 - 1 = 27 <= 7: False

3)

x <= 1

7 - 1 = 6 <= 7: True

4)

x >= -1

-7 - 1 <= 7

-8 <= 7: True

Therefore, #1, 3, and 4 are correct.

Hope this helped!

Answer:

7 x 10^-7

Step-by-step explanation:

If you use scientific notation,

move the decimal 7 places to the right to find a whole number between 1 and 9.

then, count the number of spaces.

in this instance, since the original number was a decimal, you need to put a negative power of 10.
