Hope I helped

Answer:

21/16=x

Step-by-step explanation:

[tex]8x+\frac{5}{2} =13\\2(8x+\frac{5}{2} =13)\\16x+5=26\\16x=21\\x=\frac{21}{16}[/tex]

Answer:

p=4h

Step-by-step explanation:

Knowing that Korey plants 12 trees every 3 hours we then can figure out how many trees he plants in 1 hour, by dividing the ratio (12) to the rate (3) by doing that we get 4, which is the amount of trees that he would plant in 1 hour. Then the number of tree's that he plants (p) would equal 4 times how many hours he spends planting them.

Answer:

x ≥ -3/4

Step-by-step explanation:

3(2x + 5) ≥ 2(x + 6)

Distribute

6x+15 ≥ 2x + 12

Subtract 2x from each side

6x-2x+15 ≥ 2x-2x + 12

4x+15 ≥ 12

Subtract 15 from each side

4x+15-15 ≥ 12-15

4x ≥ -3

Divide each side by 4

4x/4 ≥ -3/4

x ≥ -3/4

Answer:

A

Step-by-step explanation:

2/3x + 4 = 2/3 (x + 4/(2/3)) = 2/3 (x + 6)

Answer:

x < 5

Step-by-step explanation:

You can solve an inequality much like you would solve a normal equation.

There are 2x on the left side of the inequality, so divide both sides by two to find what x equals:

2x < 10

(2x)/2 < (10)/2

1x < 5

x < 5

Answer:

[tex] {b}^{4} + 1[/tex]

Your teacher messed up the question so just put the top right answer and ask your teacher if they did accidently miss-type.

Step-by-step explanation:

The first thing to do in this equation is look at the exponents. When multiplying a variable (or any number equal to itself with the same exponent) you only have to add the exponent. So for a, you would add the exponents to get 0, so a to the power of 0 is 1, because any number to the power of 0 is 1. For b, we would add the 3 and 1. (When no exponenet is present in a number then it is 1, so for this I added 3 and 1). So it would be 4. The correct answer is

[tex] {b}^{4} + 1[/tex]

Step-by-step explanation:

Answer:

17/25

Step-by-step explanation:

First put it into fraction form: 68/100

Simplify in no particular order just make sure that what you do to the top, you do to the bottom: 68÷2=34 100÷2=50

Simplify as many times needed: 34/50 34÷2=17 50÷2=25

You have your answer! 17/25

The fraction in the simplest form of the decimal 0.68 is 17 /25.

The decimal form is 0.68. We are told to convert to the fraction form in it simplest form. Therefore,

0.68 = 68 / 100 = 17 / 25

The logic behind it is moving the decimal 2 points forward . This beget 2 zero's in the denominator. Moving the decimal 2 points forward makes 0.68 to become 68 and the denominator takes 2 zero's which makes it the same as 68 / 100. When we reduce it we get 17 /25.

Answer:

x = tan⁻¹(⅘)

Step-by-step explanation:

We can solve for x by using trigonometric ratios (sin, cos, and tan)

We need to apply the appropriate ratio that uses the two sides 8 and 10 from the perspective of x. See attached image for information about ratios. (Source: Math is Fun)

The tangent ratio is opposite divided by adjacent. It will relate x to the two sides. So we would write

tan(x) = ⁸⁄₁₀

Then we simplify and move the tan to the other side by multiplying both sides by the inverse of tan (since you cannot divide by tan)

tan(x) = ⅘

x = tan⁻¹(⅘)

Then we can use a calculator to evaluate x

If you want to find y, now that you have two angles of the triangle, you can find the sum of 90 + x and subtract that from 180 (since all angles of a triangle add up to 180) to find y.

Answer:

f(3) = - 60

Step-by-step explanation:

To evaluate f(3) substitute x = 3 into f(x), that is

f(3) = 5(3)² - 7(4(3) + 3)

     = 5(9) - 7(12 + 3)

     = 45 - 7(15)

     = 45 - 105

     = - 60

Answer:

There are 12 boys in Ms. Stell's World History Class.

Step-by-step explanation:

The ratio we are given is 5:4.

*5 is the simplified version of 15

*4 is the simplified version of x (total number of boys)

The first thing we need to do is find the number that gives us the total number of girls (15)

5*3 = 15.

Now we do that for the 4.

[tex]\frac{5*3}{4*3}[/tex] = [tex]\frac{15}{12}[/tex]

The answer should be 15:12
