Answer:
-22.4+12.8
Step-by-step explanation:
If the temperature started at 22.4 below zero you would write that as -22.4 because it had risen 12.8 degrees you would add those 12.8 degrees to -22.4
Answer:
34
Step-by-step explanation:
|2 - 4a| - 2(b - 7)
|2 - 4(3)| - 2(-5 - 7)
|2 - 12| + 10 + 14
|-10| + 10 + 14
10 + 10 + 14
20 + 14
34
Best of Luck!
Answer:
Step-by-step explanation:
Factor the polynomials.
x^2-4 = (x+2)(x-2)
x^2+5x+6 = (x+3)(x+2)
(x^2-4)/(x^2+5x+6) = (x+2)(x-2)/[(x+3)(x+2)] = (x-2)/(x+3)
-3(n-3)
Check out the work in the picture.
Answer:
a = 14, x = 55, y = 60
Step-by-step explanation:
a: Find the number that is between 10 and 18, 10 + 18 = 28 divide by 2 = 14, so a = 14
x: Due to corresponding angles theorem, so x = 55 degrees
y: Straight line is 180 degrees, and as we can see at the left side of the image there's a straight line where only 55 degrees was identified so 180 - 55 = 125 and since x = 55 degrees due to corresponding angles, the angle above y is 120 also due to corresponding angles. A quadrilateral is 360 degrees, so:
125 + 55 + 120 + y = 360
180 + 120 + y = 360
300 + y = 360
y = 60
