Answer:

3x=y

3x-y=0

(y-75)+(X+25)=90

X+y=90+50

X+y=140

3x-y+X+y=0+140

4x=140

X=35(girls)

y=105(boys)

domain: (4, 1, 0, -1, 1)

range: (2, 3, 0, -1, -3)

Step-by-step explanation:

domain: x-values

range: y-values

Answer:

Domain: {-1, 0, 1, 4}       Range: {-3, -1, 0, 2, 3}

Step-by-step explanation:

Hi there,

To find the domain, list all of the x values and put them in numerical order. Don't repeat the same numbers.

Do the same thing for the y values when finding the range.

Hope this helps. Cheers.

Answer:

b < - [tex]\frac{3}{7}[/tex]

Step-by-step explanation:

Given

[tex]\frac{2}{7}[/tex] > b + [tex]\frac{5}{7}[/tex] ( multiply through by 7 to clear the fractions )

2 > 7b + 5 ( subtract 5 from both sides )

- 3 > 7b ( divide both sides by 7 )

- [tex]\frac{3}{7}[/tex] > b , then

b < - [tex]\frac{3}{7}[/tex]

7(8)?

Answer:

A) Samuel traveled faster in the first 15 minutes than he did in the last 15 minutes

Step-by-step explanation:

This is the only true option. B is incorrect because he traveled a different amount of miles (meaning at different speeds), so he couldn't have traveled at a constant pace. C is incorrect because Samuel traveled faster in the period than the second. D is incorrect because he traveled 6 miles first, than 4 miles. Add them to get a total of 10 miles, not 9.

Hope it helps!

Answer:

1. x = 5

Step-by-step explanation:

1.

The Trapezoid Midsegment Theorem states that a line segment connecting the midpoints of the legs of the trapezoid is parallel to the bases, and equal to half their sum.

In this problem you can see that 5x - 1 is the midsegment of the trapezoid, so using the rule:

[tex](21 + 27) / 2 = 5x -1[/tex]

solve:

[tex]48/2 = 5x-1\\24 = 5x - 1\\25 = 5x\\x= 5[/tex]

2. Diagonals are congruent

You can see in this picture that the diagonals are not always congruent:

The factory need 16 more employees to hire in order to keep the factory running as before.

Given that A factory has 112 workers.

When worker decided to change from an 8-hour working day into a 7-hour working day.

In that case also work is same.

              [tex]112*8=m*7\\\\m=\frac{112*8}{7} =128[/tex]

Where m is number of worker require after changing working hours.

Number of more employees = 128 - 112 = 16

Hence, The factory need 16 more employees to hire in order to keep the factory running as before.

Step-by-step explanation:

Find out the value of each card.

4 - 10 = 6

-4 + (-10) which is -4 - 10 = -14

-4 + 10 = 6

4 + (-10) which is 4 - 10 = -6

4 - (-10) which is 4 + 10 = 14

-4 - 10 = -14

-4 - (-10) = -4 - 10 = -14

4 + 10 = 14

Find the cards which have the same value and just match them up.
