Answer:
im pretty sure it would be 15%
Step-by-step explanation:
so A
Angle A is 78 because Ab is equal to the Ac
<h3>Answer:</h3>
[C] 3 + ( - 4).
<h3>Explanation:</h3>
- First the arrow begins at 0 and moves to the right 3 spaces positive, ending at 3.
- Then it moves backwards, which is subtracting left 4 spaces towards -1 past zero.
- When adding a negative to a positive, you convert it to subtraction.
- 3 + -4 is the same as 3 - 4.
<u>Correct choice</u> - [C] 3 + (- 4).
<u>Note</u>: See the picture attached.
Answer:
1. 5x +43
2. -1.5x - 7
3. 6.2 - 2x
Step-by-step explanation:
<u />
<u>Equation 1:</u>
5 (x+8) +3
First, we can distribute the 5 to the (x+8) and get 5x + 40. Distributing is when we multiply the 5 by the first number (x) and then by the second number (8) Because they aren't like terms (don't both have x's) we cannot combine then and must keep them separated by a subtraction sign
Now we have: 5x + 40 + 3
Next, we can combine the like terms. This means that any that have the same variable can be combined. So, the 5x has no other x's so he has to stay how he is. The 40 and the 3, however, can be added together to get 43.
Our finished equation is: 5x + 43
<u />
<u>Equation 2:</u>
3.6x - 7 - 5.1x
First, we can combine like terms as we learned in the last problem. This would be our x's since we have multiple.
We can add 3.6x and -5.1x and get -1.5x
Now we have: -1.5x - 7
<u />
<u>Equation 3:</u>
4 + 8x + 2.2 - 10x
We can start with either the numbers with x's or without but I'll just do the x's. So we have 8x and -10x. Adding these together would get us -2x.
Next, we can combine 4 and 2.2 and get 6.2.
Now, putting these back into our equation would look like this:
6.2 - 2x
I'm not sure how much my explanations helped, but I hope you understand!!
