Answer:

no they are not equivalent

Step-by-step explanation:

0.4/15 = 0.026

so for every minute they travel 0.026km

0.6/20 = 0.03

so for every minute they travel 0.03km

so they are not the same/equivalent

Answer:

2 4/7

Step-by-step explanation:

3/7+4/7= 7/7 or 1 whole

So you add that to the 5 and get 6, then you need 2 to get to 8 because 6+2=8

Hope this helped!!!

Answer:

2 4/7

Step-by-step explanation:

let n = number to add to 5 3/7

change 5 3/7 to improper fraction: 38

                                                            7

change 8 to become 56

                                     7

create equation:

38 + n = 56

 7               7

n = 56 - 38

       7        7

n = 18 or 2 4/7

       7

check:  5 3 + 2 4 = 8

                 7         7

5 + 2 = 7 and 3/7 + 4/7 = 1

7 + 1 = 8

Step-by-step explanation:

Answer:

1/2-5d

Step-by-step explanation: Commutative property you have to switch the order of the terms. Since your problem was -5d+1/2 just flip it, 1/2-5d.

Answer:

D

Step-by-step explanation:

So the associative and commutative properties basically say That you can change the orders of the numbers and the answer won't change (for multiplication and addition).

Your answer would be D because they added the numbers with a decimal place together, it makes it easier to look at, and add in your head.

Answer:

(4,5)

Step-by-step explanation:

Let's solve your system by substitution.

2y=x+6;3x=y+7

Step: Solve2y=x+6for x:

2y=x+6

2y+−x=x+6+−x(Add -x to both sides)

−x+2y=6

−x+2y+−2y=6+−2y(Add -2y to both sides)

−x=−2y+6

−x

−1

=

−2y+6

−1

(Divide both sides by -1)

x=2y−6

Step: Substitute2y−6forxin3x=y+7:

3x=y+7

3(2y−6)=y+7

6y−18=y+7(Simplify both sides of the equation)

6y−18+−y=y+7+−y(Add -y to both sides)

5y−18=7

5y−18+18=7+18(Add 18 to both sides)

5y=25

5y

5

=

25

5

(Divide both sides by 5)

y=5

Step: Substitute 5 for y in x=2y−6:

x=2y−6

x=(2)(5)−6

x=4(Simplify both sides of the equation)

Answer:4

I Took the test

The value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.

It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.

We have functions g(x) and h(x) shown in the figure.

g(h(x)) = 4

Taking the inverse of a function:

h(x) = g⁻¹(4)

From the set of functions g(x)

(2, 4) belongs to g(x)

(4, 2) belongs to g⁻¹(x)

g⁻¹(4) = 2

h(x) = 2

x = 4  (from the function h(x) data set)

Thus, the value of the x in g(h(x)) = 4 is 4 if the g⁻¹(4) = 2 and at x = 4 h(x) = 2 option (C) is correct.

Answer:

x2-20x+100

Step-by-step explanation:

You have to factor the expression in order to get your answer

Do this by expanding out the expression: (x-10)(x-10) Then factor by multiplying each of the components! Use the FOIL acronym to help you. FOIL stands for First, Outer, Inner, Last. Meaning multiply the first numbers of the expressions together, then the outers, then the inner two numbers, then the last two numbers of the expression.

Multiply x and x to get  , multiply x and -10 to get -10x, multiply -10 and x to get -10x, multiply -10 and -10 to get 100. Add them all together:  . Then combine like terms

The required trinomial in standard form is x²+20x+100.

Important information:

Using the formula [tex](a+b)^2=a^2+2ab+b^2[/tex], we get

[tex](x+10)^2=(x)^2+2(x)(10)+(10)^2[/tex]

[tex](x+10)^2=x^2+20x+100[/tex]

Therefore, the required trinomial in standard form is x²+20x+100.

Answer:

4x+4x+7x=180

15x=180

x=12

Step-by-step explanation:

Answer:

From the lines we know that that two sides are the same so the other angle is also 4x

the total of a triangle equals 180 so

4x+4x+7x=180

15x=180

x=12

Answer:

$0.25/1oz

Step-by-step explanation:

$4.00 / 16oz = $0.25 per ounce

Answer:

The answer is D) $0.25 for every 1 oz

Step-by-step explanation:

In order to find a unit cost of something, you divide the amount of money per item, by the amount of the product. So, you divide 4/16 and get .25. Then you know already that that is the unit cost. So, every 1 oz of the product costs 25 cents. Hope this helps :)

8 3/ 5 so that is the answer

Answer:

x is equal to -3, and y is equal to eight fifths, or 1.6

Step-by-step explanation:

Solving by elimination means to add or subtract one of the equations from the other, eliminating one of their common terms.

Because both of the provided ones have the term 5y (and no other y terms), let's use subtraction:

   3x + 5y = -1

- ( x + 5y = 5 )

   2x + 0 = -6

Which we can solve pretty quick:

2x = -6

x = -3

We can now solve either of the original equations for y:

x + 5y = 5

-3 + 5y = 5

5y = 8

y = 8/5, or 1.6

To make sure we're correct, let's test our results in the other equation:

3x + 5y = -1

3 × -3 + 5 × 8/5 = -1

-9 + 8 = -1

-1 = -1

So we're good!

D. Multiply the top equation by 2.

Answer:

D

Step-by-step explanation:

Given the 2 equations

8x + 3y = 2 → (1)

4x - 6y = - 7 → (2)

Multiplying the top equation (1) by 2 and adding to (2) will eliminate y

16x + 6y = 4 → (3)

Add (2) and (3) term by term to eliminate y

20x + 0 = - 3

20x = - 3 ( y has been eliminated )
