Answer:

Step-by-step explanation:

To do this we simply add the coefficients of x to give us our answer:

3 + 5 = 8

So our answer is 8x

One way to put this into perspective is to imagine x is the number of apples:

If you add 3 apples and 5 apples you get 8 apples.

Always do this trick when collecting like terms in algebra.

Answer: d, eight and fifty-three thousandths

Step-by-step explanation:

The number before the decimal place in the units column is a whole number (8).

The numbers after (.053) are thousandths because the whole number (8.053) consists of 4 numbers the same way a 1000 does.

Sorry I found the last bit harder to put into words, but I hope it helps :)

a high school track teams long jump record is 21 feet and 2 1/4 inches. this year Tims best long jump is 20 feet and 9 1/2 inche

Alex787 [66]

Answer:

4.75 inches.

Step-by-step explanation:

We must introduce the symbols for inches and feet.

Here we will use, x' = x feet and x" = x inches

A high school track teams long jump record is 21 feet and $2\dfrac{1}{4}$ inches i.e. 21'2.25" this year.

Now, Tim's best long jump is 20 feet and $9\dfrac{1}{2}$ inches i.e. 20'9.5".

So, the difference between the record jump and Tim's best jump is

(21'2.25" - 20'9.5")

= (21'2.25" - 21') + (21' - 20'9.5")

= 2.25" + 2.5" {Since, 1' = 12" i.e. 21' = 20' 12"}

= 4.75"

Therefore, Tim has to jump 4.75 inches farther to break the record. (Answer)

I believe your answer is:

Option C

Here’s why:

⸻⸻⸻⸻

$\text{\underline{The Slope Formula Is:}}\\\\m=\frac{y_2-y_1}{x_2-x_1}\\\\(x_1,y_1)\text{ and } (x_2,y_2)\text{ are two points given.}\\\\\text{We are given the points: } (3,5) \text{ and } (9,2).\\\\\text{\underline{The formula for the points should be:}}\\\\m=\frac{5-2}{3-9}, \text{where } (9,2) \text{ is }(x_1,y_1)\text{ and } (3,5) \text{ is } (x_2,y_2).$
