The principal wants to buy 8 pencils for every student at her school. If there are 859 students, how
many pencils does the principal need to buy?

Step-by-step explanation:

x + 8x + 90 = 180

9x = 90

x = 10

Answer:

x < - 8

Step-by-step explanation:

Given

3(x + 1) + 11 < - 2(x + 13) ← distribute parenthesis on both sides

3x + 3 + 11 < - 2x - 26

3x + 14 < - 2x - 26 ( add 2x to both sides )

5x + 14 < - 26 ( subtract 14 from both sides )

5x < - 40 ( divide both sides by 5 )

x < - 8

Answer:

x<-8

Step-by-step explanation:

3x+14<-2x-26(combine and distribute)

3x+14-14<-2x-26-14(subtract 14 from both sides)

3x<-2x-40(add 2x to both sides)

5x<-40(divide both sides by 5

x<-8(this is your final answer)

Answer:

Step-by-step explanation:

you know the sum of the angles in a parallelogram is 360 degrees

you have an angle that is 44, the Y angle is also 44 (opposite angles are equal)

360-(44+44)=360-88=272 is the sum of the angle x and its opposite

272/2=136

x=136

Answer:

28.57%

Step-by-step explanation:

In order to find the probability of selecting a yellow marble we first need to calculate the total number of marbles in the bag. We do this by adding the number of individual colored marbles together.

5 + 2 + 3 + 4 = 14 total marbles

Now that we have the total number of marbles in the bag we need to divide the number of yellow marbles by this total to get the probability in decimal form.

4 (yellow) / 14 (total) =  0.2857

Now we need to multiply this decimal by 100 to get the percentage probability.

0.2857 * 100 = 28.57%

Finally, we can see that the probability of selecting a yellow marble is 28.57%

Answer:

2.5 counters

Step-by-step explanation:

On the right, there are 8 spheres. Since the scale is balanced, we can assume there is an equivalent of 8 spheres on the left side. We can clearly see three spheres (in red), so we'll subtract that from the 8. The canisters (blue) are the same weight, and make up 5 spheres togther. So, divide by 2, and your answer is the blue canister is equal to 2.5 spheres/counters.

The percentage decrease of the apples will be 17%.

A percentage is a value or ratio that may be stated as a fraction of 100. If we need to calculate a percentage of a number, we should divide it's entirety and then multiply it by 100.

The percentage therefore refers to a component per hundred. Per 100 is what the word percent means. It is represented by %.

From 90 apples to 75 apples, the percentage decrease will be:

= (90 - 75) / 90 × 100

= 15 / 90 × 100

= 1/6 × 100

= 17%

Answer:

As well as we could multiply powers we can divide powers. This is an example of the quotient of powers property and tells us that when you divide powers with the same base you just have to subtract the exponents. When you raise a quotient to a power you raise both the numerator and the denominator to the power.
