Answer:
x = -5
Step-by-step explanation:
-2x+2(5x+18)=-4
The first thing you would have to do is distribute the positive 2 with 5x and 18 so that means you would multiply those two number inside the parenthesis.
-2x+ 10x+ 36=-4 2(5x)=10x 2(18)=36
Now you combined like terms on the other side of the -4. So since -2x and 10x are like terms because of the variables you would do -2x+10x=8x. So now your equation is 8x+36=-4. So now you want you x by itself so you would subtract 36 on both sides so positive 36 subtracted by 36 is 0 now you subtract 36 to -4 so that equals -40 because you did -4-36=-40. So now you have 8x=-40 so now you divide both sides by 8x so -40/8=-5
x=-5
tan F = opposite/base = 4/3
so answer is option a
4d + 6 = 42
4d = 42 - 6
4d = 36
d = <u>36</u>
4
d = 9
Answer:
160 quarters
Step-by-step explanation:
multiply 40 by 100, because there are 100 cents in a dollar, and divided 4,000 by 25, because there are 25 cents in a quarter
