51.65 to the nearest whole number
After the whole number 51, the next digit is 6, and since this is more than 5. So we round up the 51 to 52.
51.65 ≈ 52 to the nearest whole number.
9(n+3)=7n-3
1) distribute 9 into (n+3)
9n+27=7n-3
2) subtract 7n on both sides
2n+27=-3
3) subtract 27 on both sides
2n=-30
4) divide by 2
n=-15
Answer:
x = 20
Step-by-step explanation:
so we aren't give the angle across from 70, but we are given the degree on the outside, so if we take that and subtract it from 180 we will get the degree inside the triangle which is 70. (this also appears to be an isosceles triangle so it would be 70 anyway, but we can do this just to make sure.) Then, since all of the angles in the triangle add up to 180, we can subtract 140 (both 70 degrees) from it and we are left with 40. Divide 40 by 2 and you will get 20 which is the measure for angle x! Hope this helps
