Answer:

a. 1/5

b. (3, 3/5)

c. 1/5x = y

Step-by-step explanation:

Remember: (x, y)

0.5 = 1/2

(1/2, 1/10) = 1/10 ÷ 1/2 = 1/10 • 2 = 1/5, you can divide y/x = constant of proportionality. 1/10 ÷ 1/2.

1 2/5 = 7/5

(7, 7/5) = 7/5 ÷ 7 = 7/5 • 1/7 = 1/5, y/x = constant of proportionality. 7/5 ÷ 7.

Answer:

-25/1

Step-by-step explanation:

Answer:

His answer is wrong.

Step-by-step explanation:

-4(6-R)=12  <-- Since R is negative, -4 times -R results in a positive so, 4R.

-24+4R=12

+24       +24

--------------------

4R = 36

R= 9

Answer:

x=-6

Step-by-step explanation:

For this equation, when we remove the parenthesis, we get 5-x+6=-7+-3x+6.

Then we simplify both sides of the equation, so we get 11-x=-1-3x. When we separate the numbers and variables, we get -12=-2x. -12/2 = -6.

Answer:

$0.1 /lb.

Step-by-step explanation:

First, divide 1.99 by 19. You get 0.1047368421. To round it to the nearest hundred, look to the number 3 points away from the decimal, which is number 4. Since it is not 5 or greater, we round it down, and it would round down to 0.1.

Answer:

$2.24 per Gallon

Step-by-step explanation:

36.96 divided by 16.5 is 2.24, then to check that multiple 2.24 by 16.5 and you get the total cost of 36.96. Hope this helps.

Answer:

21 kids have to go on the trip to make the museum a better deal

Step-by-step explanation:

Zoo: y=10x+100

Museum: y=5x+200

10x+100=5x+200

5x=100

x=20

When 20 kids go on trip the costs will be the same. Therefore, once 21 kids go the museum will be cheaper then the zoo as it is increasing at a rate of 5 dollars

Answer:

it would be y=50+25x

Step-by-step explanation:

There is an extra $25 per room, and since we dont know how many rooms she has cleaned, we can use x to represent that amount. So for x amount of rooms, it will be an extra $25

Answer:

-1/4

Step-by-step explanation:

because its going up one over 4 and the lines negative!

Answer:

-1/4

Step-by-step explanation:

The slope is going down towards the right so it's negative. Rise-1 and you Run-4 so the answer is -1/4. Hope this helps :)

Answer:

A negative exponent just means that the base is on the wrong side of the fraction line, so you need to flip the base to the other side. For instance, "x–2" (pronounced as "ecks to the minus two") just means "x2, but underneath, as in 1 x 2 \frac{1}{x^2} x21 ".

Answer:

20

Step-by-step explanation:

we can see that there are already answers for 2 which is six 6+6=12 now we can see that a triangle look the same as the six over the 8mm so that must be six so 6+6+6=18 now there is still s little section missing over the 8mm (the half triangle half square) is missing a section we can see that the perimeter is 8 and the area is 6 and 6+2=8 so that little area is 2 so 6+6+6+2=20

Answer:

X=(-3)

Step-by-step explanation:

1.Subtract 8 from both sides of the equation.-(x+0)=5-8-the 0 is there because the 8 on the left side is canceled out.

2.5-8 is all you have to look at.-when you look at this you know that it will be negative because 8 is on the right of the minus sign and it is greater than 5.

3.Use a calculator or you fingers to find answer.-(4,3,2,1,0,-1,-2,-3)

Pythagorean Theorem: a² + b² = c²

Step-by-step explanation:

a is one leg of the right triangle.

b is another left of the right triangle.

c is the hypotenuse of the right triangle.

We use the Pythagorean Theorem to help us solve for missing side lengths of a right triangle.

Take that back, please delete this question.

2x+108 = 180

2x+108-108 = 180-108

2x = 72

2x/2 = 72/2

x = 36

-------

Notes:

Given : There is a line . It is divided into two parts by another line such that it forms two angles on two sides of the angle which are 2x° and 108° .

To Find : The value of x .

Solution : Given that the two angles are 2x and 108° . So , we know that the measure of a straight line is 180° . So the sum of the two angles will be also equal to 180°. That is ;

[tex]\large\boxed{\red{\bf \angle 1 + \angle 2= 180^{\circ}}}[/tex]

⇒ 2x° + 108° = 180° .

⇒ 2x° = 180° - 108° .

⇒2x° = 72°.

⇒ x =[tex]\sf \dfrac{72}{2}[/tex]

⇒ x = 36° .

Hence the value of x is 36° .

Answer:

4  1/9

Step-by-step explanation:

so if we make the fraction the same having 7 4/9 and 3 1/3

we would then make 1/3 into 3/9 (its the smae thing not simplified)

subtract 7-3=4

4-3=1

and then simplify the fraction

Answer:

15

Step-by-step explanation:

First you would plug in the 4 and 1/2 in the x and y's places, making the expression (4 - 2 (1/2))*(4 + 2 (1/2). Then you solve (below).

(4 - 2 (1/2))*(4 + 2 (1/2)

(4 - 1)*(4 + 1)

(3)*(5)
