1. -4
2. 2
four plus negative four is zero and two minus two is zero
Answer:
alot because the mass sum is 180
Step-by-step explanation:
Answer:
- a. ∠Y, ∠W, ∠X
- d. 75°
- d. 5
Step-by-step explanation:
1. The sides, shortest to longest, are 5, 10, 12. The angles opposite are in the same order (smallest to largest). Those angles are ∠Y, ∠W, ∠X.
__
2. The triangle isosceles, so the base angles are equal. The sum of angles in a triangle is 180°, so you have ...
30° + 2x = 180°
15° + x = 90° . . . . . divide by 2
x = 75° . . . . . . . . . . subtract 15°
__
3. The midline of a triangle is half the length of the base it is parallel to, so ...
ML = 10/2 = 5
It is a <em>midline</em> because it joins the midpoints of two sides of the triangle.
Answer:
The baseball mitt was $37 and the ball was $7
Step-by-step explanation:
Let m represent the cost of the mitt and let b represent the cost of the ball
Set up a system of equations:
m + b = 44
m = 5b + 2
Solve by substitution by plugging in 5b + 2 as m in the first equation:
5b + 2 + b = 44
Solve for b:
6b + 2 = 44
6b = 42
b = 7
Plug in 7 into the first equation and solve for m:
m + b = 44
m + 7 = 44
m = 37
So, the baseball mitt was $37 and the ball was $7
