Answer:

Step-by-step explanation:

You really just need a calculator for this but to solve by hand just simply separate all the variables and coefficients and then multiply them together at the end.

[tex]-9x^5y^2[/tex]

Since x = -1

[tex]-1^5[/tex] = [tex]-1*-1*-1*-1*-1[/tex] = -1

[tex]\frac{1}{3}^2= \frac{1}{3}*\frac{1}{3}=\frac{1}{9\\}[/tex]

[tex]-9*-1*\frac{1}{9}=1[/tex]

The required numbers are 18,46 and 23.

This problem requires the idea of linear equation of 1 variable.

To clear up the linear equation we also need to recognize the BODMAS policies and the way to solve algebraic equations.

in this query the sum of the 3 numbers is 87.

let us count on that the third variable be x.

the second one variable is 2x.

The first variable is (x-5).

Now according to the question,

   [tex](x-5)+2x+x=87[/tex]

⇒ [tex]4x-5=87[/tex]

⇒ [tex]4x=87+5[/tex]

⇒[tex]4x=92[/tex]

⇒ [tex]x=\frac{92}{4}[/tex]

∴ x=23

So, the third number is 23.

The second number is 2x i.e., 46.

The first number is (x-5) i.e., 18.

Step-by-step explanation:

Equivalent expressions are expressions with equal values

The equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6

The expression is given as:

2(14x-3y+28x+12.2-5y-17.5)

Collect like terms

2(14x-3y+28x+12.2-5y-17.5) = 2(14x+28x-3y-5y+12.2-17.5)

Evaluate the like terms

2(14x-3y+28x+12.2-5y-17.5) = 2(42x-8y-5.3)

Open the bracket

2(14x-3y+28x+12.2-5y-17.5) = 84x-16y-10.6

Hence, the equivalent expression of 2(14x-3y+28x+12.2-5y-17.5) is 84x-16y-10.6

Step-by-step explanation:

To solve the equation |11x + 10| = 22, we need to consider two cases: one where the expression inside the absolute value is positive and one where it is negative.

Case 1: (11x + 10) is positive:

In this case, the equation becomes 11x + 10 = 22. Solving for x, we subtract 10 from both sides, resulting in 11x = 12. Dividing by 11 gives x = 12/11.

Case 2: (11x + 10) is negative:

Here, the equation becomes -(11x + 10) = 22. Simplifying, we have -11x - 10 = 22. Adding 10 to both sides gives -11x = 32. Dividing by -11 yields x = -32/11.

Thus, the solution set for the given equation is x = 12/11 and x = -32/11, representing the two possible values of x that satisfy the equation |11x + 10| = 22.

Step-by-step explanation:

The 390 ml of pure water will you need to add to obtain the desired solution.

It is required to find how much pure water will you need to add to obtain the desired solution.

A part of a whole expressed in hundredths a high percentage of students attended. Also the result obtained by multiplying a number by a percent the percentage equals the rate times the base.

Given:

You know that the current solution is 70% alcohol, so the amount of alcohol present is 70% of 520 = 364

Let x be the amount of water to add.  Then the new total amount would be 520 + x.  To arrive at a solution that is 40% alcohol, you would want the amount of alcohol to be 40% of the new total.

So...

364 = .40 * (520 + x)

By simplify we get,

364=208+0.40x

364-208=0.40x

156=0.40x

x=390 ml

we must add 390 ml of water to get the 40% solution.

Therefore, the 390 ml of pure water will you need to add to obtain the desired solution.

Answer:

Angles 1 and the angle provided  (88°) are supplementary meaning their angles with total 180°. Therefore m<1 +88=180

m<1=92

We can see that by the arrow on the 2 lines that they are parralel and paralel lines form congruent angles. Therefore, the m<64 will equal that of 3

m<3=64

Now,  that we have the m<1 and the m<3 we know that the m<2 is 24

This is because the measure of the interior angles of any triangle add up to 180.

92+64+m<2=180

156+m<2=180

m<2=24

Now, we see that the m<3+m<4+81 will total 180°. the m<3 is 64 so:

64+81+m<4=180

145+m<4=180

m<4=35

Now, by using the rule that the measure of the interior angles of any triangle add up to 180 we see that the m<4+m<5+64=180

m<4=35

35+64+m<5=180

99+m<5=180

m<5=81

Step-by-step explanation:

First start by choosing a number. for example: 20. Then Sum The number 3 times 20 + 20 + 20 = 60. You need to get to 144 so I pass 20 and go to 30. 30 + 30 + 30 = 90. Lets pass and go to 40. 40 + 40 + 40 = 120. Its close. when Im close I Start summing 41, 42 and so on. 48 + 48 + 48 = 144. I reach to 144. So that means 48 is the answer.

Answer:

Cost of child movie = x = $8

Cost of adult movie = y = $10.25

Step-by-step explanation:

Let cost of child movie = x

Cost of adult movie = y

Now converting statements into mathematical expressions:

Hansen family bought 2 child and 2 adult movie tickets and paid $36.50.

[tex]2x+2y=36.50[/tex]

Owens family bought 5 child and 2 adult tickets and paid $60.50. [tex]5x+2y=60.50[/tex]

Let:

[tex]2x+2y=36.50--eq(1)\\5x+2y=60.50--eq(2)[/tex]

Subtract both equations:

[tex]2x+2y=36.50\\5x+2y=60.50\\- \:\:\: - \:\:\:\:\:\:\:\: -\\--------\\-3x=-24\\x=\frac{-24}{-3}\\x=8[/tex]

So, we get Value of x =8

Now, putting value of x in eq(1) to find value of y

[tex]2x+2y=36.50\\Put \: x=8\\2(8)+2y=36.50\\2y=36.50-16\\2y=20.5\\y=\frac{20.5}{2}\\y=10.25[/tex]

So, we get Value of y = 10.25

So,

Cost of child movie = x = $8

Cost of adult movie = y = $10.25
