Answer:

Step-by-step explanation:

To solve an equation, we can only have one variable. In this case, we are given the system 2x = 5y + 14. However, we are given the value of x in terms of y. We can substitute 10y in for 2x and solve.

10y = 5y + 14

First, we need to get all the variables on one side of the equation, so we subtract 5y.

5y = 14

Divide by 5

y = 14/5 or 2 4/5 or 2.8

Now for the x part.

2x = x + 14

Subtract 1x

x = 14

Now we check our answer.

2(14) = 5(2.8) + 14

28 = 14 + 14

28 = 28

Because 28 equals 28, our solutions are correct.

Answer:

x = 12 degrees

Step-by-step explanation:

This isosceles triangle has two equal sides and thus two equal angles.  We find the measure of angle 2 by subtracting 76 degrees from 180 degrees, and then dividing the result (104 degrees) by 2:  m<2 = 52 degrees.

Then m<2 = 52 degrees = 3x + 16, or

                    52 degrees - 16 degrees = 3x, or:

                     36 degrees = 3x

Thus, x = 12 degrees

Answer: d

Step-by-step explanation:

r+g less than or equal to 1,200

r less than or equal to 500

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Let r represent the number of reserved seats and g represent the number of seats for general  admission.

Since the school has 1,200 concert tickets for sale, hence:

r + g ≤ 1200   (1)

Also, there are at most 500 reserved-seat tickets. Hence:

r ≤ 500  (2)

The pair of inequalities models the number of  tickets that can be sold is r + g ≤ 1200 and r ≤ 500

Answer:

The correct option is C. 47.10 inches

Step-by-step explanation:

Diameter of the tire rim is given to be 15 inches

So, The radius of the tire rim will be 7.5 inches

Now, we need to find the circumference of the tire rim

And, The circumference of the tire rim is given by the formula :

Circumference = 2·π × radius

⇒ Circumference of the tire rim = 2 × 3.14 × 7.5

⇒ Circumference of the tire rim = 47.1 inches

Therefore, The correct option is C. 47.10 inches

Answer:

216

Step-by-step explanation:

I'm sure there is a simpler way to do this but this is how I did it.

First divide 18 by 6 because it triples every 6 hours.

18/6=3

This means it will triple three times

Then triple the value three times

#1. 8x3=24

#2. 24x3=72

#3. 72x3=216

In 18 hours the virus will infect 216 people.

Answer:

x=-5

Step-by-step explanation

The first box has eight x's and six 1's which means that it would be written as 8x+6

The second box has four x's and fourteen -1's which means that it would be written as 4x-14

You set them equal to one another

8x+6=4x-14

You subtract 4x from both sides

4x+6=-14

Subtract 6 on both sides

4x=-20

Divide 4 on both sides

x=-5

Answer:

$45

Step-by-step explanation:

let's work backwards. We know that it was 20% off, or otherwise 80% of the original cost. Let's represent the original cost with x:

0.8x = 36

Now we solve for x by dividing both sides by 0.8:

x = 45

Thus, the sweater was originally $45

Answer:

x = 18

Step-by-step explanation:

The inner and outer triangles are similar, thus the ratios of corresponding sides are equal, that is

[tex]\frac{80}{80+2x}[/tex] = [tex]\frac{60}{60+27}[/tex] = [tex]\frac{60}{87}[/tex] ( cross- multiply )

60(80 + 2x) = 6960 ← divide both sides by 60

80 + 2x = 116 ( subtract 80 from both sides )

2x = 36 ( divide both sides by 2 )

x = 18

Step-by-step explanation:

w=5_4    5 ontop 4 in the bottom

Answer:

w=5/4

Step-by-step explanation:

Answer:

[tex]A = 15[/tex]   [tex]B = 20[/tex]   [tex]C = 25[/tex]

[tex]D = 30[/tex]   [tex]E = 40[/tex]   [tex]F = 50[/tex]

[tex]D = 3[/tex]    [tex]E = 4[/tex]     [tex]F = 5[/tex]

Step-by-step explanation:

Given

Similar Triangles: ABC and DEF

[tex]A = 15[/tex]

[tex]B = 20[/tex]

[tex]C = 25[/tex]

Required

Determine the sides of DEF

No options were given, so I will solve on a general terms.

Since both triangles are similar, then the following relationship exists.

DEF = ABC * n

i.e.

[tex]D = A * n[/tex]    [tex]E = B * n[/tex]     [tex]F = C * n[/tex]

Where

[tex]n = Scale\ Factor[/tex]

Assume n = 2.

So, we have:

[tex]D = A * n[/tex]    

[tex]D =15 *2[/tex]

[tex]D = 30[/tex]

[tex]E = B * n[/tex]    

[tex]E = 20 * 2[/tex]

[tex]E = 40[/tex]

[tex]F = C * n[/tex]

[tex]F = 25 * 2[/tex]

[tex]F = 50[/tex]

Assume [tex]n = \frac{1}{5}.[/tex]

So, we have:

[tex]D = A * n[/tex]    

[tex]D =15 *\frac{1}{5}[/tex]

[tex]D = 3[/tex]

[tex]E = B * n[/tex]    

[tex]E = 20 * \frac{1}{5}[/tex]

[tex]E = 4[/tex]

[tex]F = C * n[/tex]

[tex]F = 25 * \frac{1}{5}[/tex]

[tex]F = 5[/tex]

So, the possible sides are:

[tex]A = 15[/tex]   [tex]B = 20[/tex]   [tex]C = 25[/tex]

[tex]D = 30[/tex]   [tex]E = 40[/tex]   [tex]F = 50[/tex]

[tex]D = 3[/tex]    [tex]E = 4[/tex]     [tex]F = 5[/tex]

Answer:

3.5

Step-by-step explanation:

The constant rate of proportionality, k, is expressed as [tex]k = \frac{y}{x}[/tex], and shows that two quantities are proportional to each other. In this logic, rearranging this in terms of y gives us:

[tex]y = kx[/tex]

Thus we can determine that k is 3.5, in this case.
