Answer:

77,700 students graduate on (HBCU)

210,000*.37=77,700

(I am not really sure about this )

Answer:

Step-by-step explanation:

1) Number of jeans = x

Number of blouses = y

Total items = 6

x +  y = 6 -------------------(I)

       y = 6 - x

Cost of 'x' jeans =  300 *x = 300x

Cost of y blouses = 100 * y = 100y

Total amount  = Php. 1000

300x + 100y = 1000 ------------(II)

2) Substitute y = 6 - x in equation (II)

         300x + 100(6-x) = 1000

300x + 6*100 - x *100 = 1000

 300x + 600 - 100x   = 1000

                200x + 600=1000

                          200x = 1000 - 600

                          200x = 400

                               x = 400/200

x = 2

Plugin x = 2 in equation (I)

2 + y = 6

     y = 6 - 2

     y = 4

Number of jeans = 2

Number of blouses = 4

3) This equations have only one solution. So, they are consistent and independent

Answer:

1) 0.9 = 9/10

2) 2 x (4² - 5) = 2 x (16-5) = 2 x 11= 22

3)  t/4=16 16*4=t 64=t t=64

4) 2.4p=7.56  p=7.56/2.4  p=3.15

5) 8*5=40m² 40*4=160m³ v=160m³

6) 3x=27  x=27/3  x=9

Step-by-step explanation:

Given that,

12 over 30 and 18 over 45

We need to tell whether the ratios are Proportional or Not Proportional.

[tex]\dfrac{12}{30}=\dfrac{2}{5}[/tex]

And

[tex]\dfrac{18}{45}=\dfrac{2}{5}[/tex]

The ratio for both fraction is same i.e. 2/5 Hence, each ratios are Proportional.

Answer: The proportion of businesses who did not respond = 54.67%

Step-by-step explanation:

Given : Total businesses = 150

Businesses responded = 68

Businesses did not respond =  150- 68 = 82

The proportion of businesses who did not respond =

[tex]\dfrac{\text{Businesses did not respond}}{\text{Total businesses}}\times100[/tex]

[tex]=\dfrac{82}{150}\times100=54.67\%[/tex]

Hence, the proportion of businesses who did not respond = 54.67%

Answer:

Step-by-step explanation:

Answer:

(0,5)

(2,1)

(4,-3)

Step-by-step explanation:

so all you have to do is plug in the x value and if the y value comes out to be whatever is matches up with then it is a solution to the equation for example if you plug in 0 to y=-2x+5 then you get 5 and below it says that when x=0 then y=5 which is true so that would be an answer now if you plug in 2 then you get 1 and it says that when x=2 y=9 which is not correct. sorry if this doesnt make sense its so hard to explain virtually

Answer:

y = 5/4 (x) + 7

Explanation:

Slope of a line (m): (y₂ - y₁) ÷ (x₂ - x₁)

       Slope: (2 - -3) ÷ (-4 - -8) = 5 ÷ 4 = 5/4

Point slope form: y - y₁ = m (x - x₁)

       Equation: y - 2 = 5/4 (x - -4)

                        distribute the 5/4

                        y - 2 = 5/4 (x) + 5

                        add 2 to both sides

                        y = 5/4 (x) + 7

Step-by-step explanation:

When Dividing fractions, use the reciprocal of 3/4

7 1/2 times 4/3 equals

10

Answer:

10

Step-by-step explanation:

You would do something called KCF Keep, Change, and Flip.

You would keep the 7 1/2 and change the divided sign to multiplying sign and flip the 3/4 so its a 4/3 and then multiply it.

15/6 times 4/3. 15 x 4 = 60

                           2x3=   6

so I can be 60/6 but you would simplify and 6 goes into 60  10 times. so 10 is you answer

there actually asking how many meters would make 1 centimeter

On the ruler 1 whole centimeter is 10 meter. (The longer line behind the number is the 10th meter )

Dividing fractions

1 ÷ 1/10

Steps

Change the whole number which is 1 into a fraction.

1/1 ÷1/10

Flip the second fraction in the equation.

1/1 ÷ 10/1

Then change the division sign to a multiplication sign. So were multiply instead.

1/1 × 10/1

Multiply the fractions and your answer should be 10/1 .

This fraction is also changed to a whole number.

10/1 = 10
