7 = -x + 3
7- 3 = -x
4 = -x
x = -4 <===== 10 is not a solution
Answer:
x = -3/8
Step-by-step explanation:
4(3-2x)=15
Distribute
12 -8x = 15
Subtract 12 from each side
12-8x-12 = 15-12
-8x =3
Divide each side by -8
-8x/-8 = 3/-8
x = -3/8
The answer i got was 49-9b^2
Answer: 37.778 degrees
Step-by-step explanation:
The third digit to the right of the decimal is thousandths. If the next digit to the right of that is 5 or more, add one to the thousandths. Otherwise leave it as is. Just drop everything to the right of the place you rounded to.
7 is greater than 5, so add 1 to the 7 in the thousandths place and get
37.778
Answer:
45
Step-by-step explanation:
The sum of interior angles in a triangle is equal to 180
2x - 12 + 2x + 17 + 9x - 7 = 180 add like terms
13x - 2 = 180 add 2 to both sides
13x = 182 divide both side by 13
x = 14
m<X = 2x + 17 replace x with 14
2*14 + 17 = 45
