Step-by-step explanation:
solve the ineq first then plot on the number line so,
-2(4x + 5) ≤ 30
-8x - 10 ≤ 30
-8x ≤ 40
x ≥ -5
therefore, option A is correct.

Answer:
3.6399 = 3.640
Step-by-step explanation:
Rounding to nearest thousandth means rounding to 3 decimal place
(0 to 4) =round down
(5 to 9)= round up
w/7 + 2 = 1
<em><u>Subtract 2 from both sides.</u></em>
w/7 = -1
<em><u>Multiply both sides by 7.</u></em>
w = -7
The value of w is equal to -7
Answer:
262 books sold
Step-by-step explanation:
This is a very vague word problem, but if it truly is just asking the amount of books sold (regardless of music or science), here's how to get the answer:
1. 287+134=421 - first you want to add together the two types of books to get the total amount of books in the store
2. 421-x=159 - create an equation and solve.
3. -x=-262 - follow order of operations and subtract 421 on both sides in order to isolate the variable
4. x=262 - divide each side by -1 to make the variable positive.
If you'd like an easier way, you can just:
1. 421-159=262 - it's easier, but my math teacher would count us wrong if we didn't do equations a specific way. Good luck!
The measure of angle 4 would be the same as its opposite exterior angle which is given. It will have a measurement of 38 degrees. These angles are called alternate exterior angles. Hope this answers the question. Have a nice day. Feel free to ask more questions.
