A) constant=40, coefficient=7.50, variable=h
B)7.50h+.20s+40
7.50(25)+.20(300)+40
187.5+60+40=287.5$

You find that the product of 67 and 5 is 335. How can you use addition to check if you are correct? How can you use division to

daser333 [38]

Answer: Well, there is two ways for addition and two ways for division. either Add 67 5 times (67 + 67 + 67 + 67+ 67) to get 335 or add 5 67 times (5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 + 5 etc.) to get 335, And for division (my favorite part) Either get 335 and see if 67 can be multiplied to get 3, 33, or 335. and if either 3, 33, or 335 is to big subtract what you get when you multiply (Enter Number) with 67 to get anything remotely close to 3, 33, or 335. (NOT MORE THAN 3, 33, OR 335 ONLY EXACT OR LESS THAN) or do the exact same with 5.

lesantik [10]

Answer: SECOND OPTION.

Step-by-step explanation:

For this exercise it is important to remember "Rigid transformations".

Rigid transformations are those transformation that preserves length. These are the following:

- Reflection.

- Tanslation.

- Rotation.

According to the information given in the exercise, the triangle JKL was translated 12 units vertically and then reflected over the y-axis to create triangle J'K'L'. Therefore, JKL and J'K'L' are congruent.

Knowing the above, you can set up the following equation:

$2x-4=8$

The final step is to solve for "x" in order to find its value. You get that this is:

$2x=8+4\\\\x=\frac{12}{2} \\\\x=6$
