Answer:

55x + 148/24

Explanation:

Answer:

111,200,204,210,211

Step-by-step explanation:

Answer:

1) y = - 3 and x = 3

2) x = 9/2 and y = 9

Step-by-step explanation:

Substitute x= 0 to find y and y=0 to find x

Answer:

false

Step-by-step explanation:

because real number values of x are not the same

Given:

The equation is

[tex]20y-10x+5[/tex]

To find:

The slope intercept form of the given equation.

Solution:

The slope intercept form of a linear equation is

[tex]y=mx+b[/tex]

Where, m is slope and b is the y-intercept.

We have,

[tex]20y-10x=5[/tex]

We need to isolate y. Add 10x on both sides.

[tex]20y-10x+10x=5+10x[/tex]

[tex]20y=5+10x[/tex]

Divide both sides by 20.

[tex]\dfrac{20y}{20}=\dfrac{5+10x}{20}[/tex]

[tex]y=\dfrac{5}{20}+\dfrac{10x}{20}[/tex]

[tex]y=\dfrac{1}{4}+\dfrac{x}{2}[/tex]

[tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex]

Therefore, the slope intercept form of the given equation is [tex]y=\dfrac{1}{2}x+\dfrac{1}{4}[/tex].

Answer:

x = 11

Step-by-step explanation:

x + 9 = 20 (Subtract 9 from both sides)

x = 20 -9

x = 11

Verify:

11 + 9 = 20 (Correct)

Answer:

y = 2/5x + 18.

Step-by-step explanation:

The line will have the same slope of 2/5.

Using the point-slope form of a line:

y - 12 = 2/5(x - -15)

y - 12 = 2/5(x + 15)

y = 2/5x + 6 + 12

y = 2/5x + 18.

Answer:

y  = (2/5)*x + 18

Step-by-step explanation:

Because the line is parallel to the line y = 2/5 x + 17, the slope of the new line has to be the same as well. So far, we have y = (2/5)*x .

Now what we can do is plug in -15 for x and see what we get for y. Because we get -6, we need 18 more to make it 12. Because of that, the y-intercept is 18 to make the equation of the line y  = (2/5)*x + 18.

Answer:

x= 2/3

Step-by-step explanation:

if they are equating,

10x +38 = 40+7x

10x-7x = 40-38

3x = 2

x= 2/3

Answer:

x = 0.6666666667

Step-by-step explanation:

Simplifying

10x + 38 = 40 + 7x

Reorder the terms:

38 + 10x = 40 + 7x

Solving

38 + 10x = 40 + 7x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-7x' to each side of the equation.

38 + 10x + -7x = 40 + 7x + -7x

Combine like terms: 10x + -7x = 3x

38 + 3x = 40 + 7x + -7x

Combine like terms: 7x + -7x = 0

38 + 3x = 40 + 0

38 + 3x = 40

Add '-38' to each side of the equation.

38 + -38 + 3x = 40 + -38

Combine like terms: 38 + -38 = 0

0 + 3x = 40 + -38

3x = 40 + -38

Combine like terms: 40 + -38 = 2

3x = 2

Divide each side by '3'.

x = 0.6666666667

Simplifying

x = 0.6666666667

80 + 35 = 115

180 - 115 = 65

the answer is 65

Step-by-step explanation:

what's the question??

Answer:

The first two options

Step-by-step explanation:

The formula is V= l x w x h So that is why the first one works.

The second one works because of the commutative property of multiplication which says that the number don't have to be in a certain order so They multiplied the first 2 numbers which equals 12 1/2 which means 12 1/2 x 1/2 would work

Answer:

Shortest side = 7 inches.

Medium side = 9 inches.

Longest side = 10 inches.

Step-by-step explanation:

Let the shortest side be x.

Translating the word problem into an algebraic equation, we have;

Shortest side = x

Medium side = x + 2

Longest side = x + 3

The perimeter of a triangle is given by the addition of all its three (3) sides.

Mathematically, the perimeter of a triangle is given by the formula;

[tex] P = A + B + C [/tex]

Substituting into the equation, we have;

26 = x + x + 2 + x + 3

26 = 3x + 5

3x = 26 - 5

3x = 21

x = 21/3

x = 7 inches.

Therefore, the length of the three sides are;

Shortest side = x = 7 inches.

Medium side = x + 2 = 7 + 2 = 9 inches.

Longest side = x + 3 = 7 + 3 = 10 inches.

Answer:

B. I think

Step-by-step explanation:

1.50 times 86 equals 129 witch would mean Diana bought 86 sodas

8 is equal to 1 pizza so Dianna could have bought 1 pizza

86>1

8+129 is 137 so I think the answer is B.

Answer:

x = [tex]\frac{3}{4}[/tex]

Step-by-step explanation:

Since you cannot subtract -1 from 4x, you multiply 2 × 4x = 8x

Now, you have 8x - 1 + 3 = 7

Seperate the 8x from the other numbers

8x = 1 - 3 + 7 ---> 6

8x = 6

Now simplify

x = [tex]\frac{6}{8}[/tex]  <----- to reduce, divide the numerator and denominator by 2

Hence,

x =  [tex]\frac{3}{4}[/tex]

Answer:

  A. exponential; constant % rate of change

Step-by-step explanation:

Each round has 50% of the players of the previous round, so the rate of change is a constant percentage. That makes the function a decaying exponential function, matching choice A.
