PLEASE HELP- Tito solved this equation (Click picture) Which of the following properties did he use? Check all that apply.

olchik [2.2K]

<span>The correct answers are ‘distributive property' and ‘addition property of equality'. The distributive property can be observed between the first and second lines when the brackets are expanded. The addition property can be seen when -2x is added to both sides to change 6x + 10 - 2x = 22 + 2x - 2x into 4x + 10 = 22.</span>

Mrs. Hinely grows roses. There are 6 roses on each of her 10 rose bushes. How many roses in all are on Mrs. Hinely's rose bushes

diamong [38]

In order to find the total number of roses, we can use multiplication. Since there are 6 roses on each bush, we can say that the answer is: 6+6+6+6+6+6+6+6+6+6. Since multiplication is a way to quickly add the same number, we can use 6*10. This becomes 60.

Good luck :D

7/10 ÷ 1/5 <br> pls i need help

blondinia [14]

7/10 ÷ 1/5 = 3 1/2 because if you just find the reciprocal of the second number (in this case 1/5) and then simply multiply the two numbers straight across after you find the reciprocal, you will need to convert and simplify as needed, and then you get your answer.

Solve the equation. | x | -7 =6

guapka [62]

Hi there!

Let's solve this equation step by step!
$|x| - 7 = 6$

First add 7 to both sides.
$|x| = 13$

Next we need to take a look at the meaning of the stripes between our variable. Those stripes mean we are dealing with an absolute value function. The absolute value stripes make everything between the stripes positive; also when we plug in a number. In this particular question we can plug in both -13 and 13 at the position of n, because when -13 is made positive, it fulfils the equation.

Hence,
$x= 13$ or $x = - 13$

~ Hope this helps you!
