There are 15 female performers in a dance recital. The ratio of men to women is 2:5. How many men are in the dance recital?

Answer:

2 × 1 +2 +2×2 =8

2+2+4=8

8=8

3×1 +3× -2 + 4×2 =5

3-6+8=5

5=5

1+2 × -2 +2 = -5

1-4+2= -5

-5 = -5

Answer:

7.75

Step-by-step explanation:

found unit rate divided 4.80 by 96 = 0.05

0.05 x 155 = 7.75

Answer:

The number is 9

Step-by-step explanation:

• Let the number be x

[tex]{ \tt{3x - 7 = 20}} \\ [/tex]

» Add 7 to either sides following addition rule of equality:

[tex]{ \tt{(3x - 7){ \red{ + 7}} = 20{ \red{ + 7}}}} \\ { \tt{3x = 27}}[/tex]

» Divide either sides by 27:

[tex]{ \tt{ \frac{3x}{ \blue{3 }} = \frac{27}{ \blue{3}} }} \\ \\ { \tt{x = 9}}[/tex]

Answer:

10/3 or 3 1/3

5/1 · 2/3 = 10/3

You can't simply this anymore farther.

Also the proper form of 10/3 is also 3 1/3.

Answer:

88 more people

Step-by-step explanation:

Let the additional number of people that can be seated be n.

Maximum capacity of auditorium= 250

This means that the amount of people in the auditorium can be exactly 250 or less than that. Thus, the inequality sign used is '≤', which can be read as 'less than or equal to'.

Since there are already 162 people in the auditorium,

162 +n ≤ 250

Subtract 162 from both sides:

n ≤ 250 -162

n ≤ 88

Thus, 88 more people can be seated.

Note:

An equation with an inequality symbol is solved the same way as one with an equal sign, except when dividing both sides of the equation by a negative number (i.e. a number lesser than zero). In that case, the direction of the inequality sign will change:

• > becomes < and vice versa

• ≥ becomes ≤ and vice versa

Answer:

10y+5

Step-by-step explanation:

5 x 2y = 10y

5 x 1 = 5

Answer:

10y + 5

Step-by-step explanation:

Expand the expression!

(2y + 1) * 5 : We have to multiply each factor by 5

2y * 5 = 10y

1 * 5 = 5

Combine those values, and we get 10y + 5 :)

This is just a linear function in disguise, so there's only one solution

Answer:

y=8x-13

Step-by-step explanation:

When you're finding a perpendicular line, you take the opposite of the slope. The slope in this equation is 1/8, so a perpendicular line will have the slope of 8. So we already know y=8x+b.

Plug in your x and y values from the ordered pair and you get -5=8(1)+b. 8×1 is just 8, so it's -5=8+b. Subtract 8 from both sides and you get -13=b.

Answer:

x = 35

Step-by-step explanation:

The angles are alternate so their measure is equal:

2x = x + 35 get the like terms on the same side of the equation

2x - x = 35 subtract

x = 35

Measure

2x = 70 and

x + 35 = 70

Answer:

x = 80

Step-by-step explanation:

We have, 150% · x = 120

or, 150/100 · x = 120

Multiplying both sides by 100 and dividing both sides by 150,

we have x = 120 · 100/150

x = 80

If you are using a calculator, simply enter 120×100÷150, which will give you the answer.

[RevyBreeze]

Answer:80

Step-by-step explanation:

we have,

150x/100 = 120

x = 120 x 150/100

x= 80

Separate the variables:

y' = dy/dx = xy   ⇒   1/y dy = x dx

Integrate both sides:

∫ 1/y dy = ∫ x dx

ln|y| = 1/2 x² + C

Given that y(0) = 1, we have

ln|1| = 1/2 • 0² + C   ⇒   C = 0

so that the particular solution is

ln|y| = 1/2 x²

Solving for y gives

y = exp(1/2 x²)

Answer:

The inequality that describes this problem is , and the minimum number of computers he must sell is 25.

Step-by-step explanation:

Since there is no restriction on the number of computers he must sell, an inequality can help us describe the situation.

Writing the inequality.

Let x be the number of computers he sells the next month, since he receives a bonus of $100 per computer he sells the total amount he will make for x computers is

And since he wants to make $2,500 in bonuses, the inequality that describes that situation is

Solving the inequality.

In order to find the exact number of computers he must sell, we need to solve for the inequality.

Since 100 is multiplying to x, in order to move that 100 to the other side, we need to apply the inverse operation to multiplication, which is division. We can then divide both sides by 100

So then we can simplify to get

Thus the minimum number of computers he must sell is 25.

Answer: M = 32

Step-by-step explanation:

We can add 2 to each side of the equation to get M/4 = 8.

We can then multiply each side of the equation by 4 to get M = 32.
