Answer:
x=3
Step-by-step explanation:
Simplify 3(x-2)+5X
= 8x-6=18
Add 6 to both sides
8x=24
Divide by 8
x=3
The vertex is where two lines make a point and the answer would be letter C. A
Answer:
Step-by-step explanation:
1. There is a total of 16 outcomes
2. To get outcomes with a sum GREATER than 5, we have
2+4, 3+3, 3+4, 4+2, 4+3, 4+4 for a total of 6 outcomes.
3. To spin the same number twice, the possible outcomes are
1-1, 2-2, 3-3, 4-4 for a total of 4 outcomes.
Answer:
1. a + b + c = 180
2. b + d = 180
3. d = a + c
Step-by-step explanation:
1. a + b + c = 180:
Angles in a triangle add up to 180
2. b + d = 180:
Angles in a straight line equal 180 because they are supplementary angles
3. d = a + c:
ΔACD is an exterior angle, and ΔACB is interior adjacent, hence ∠a and ∠c add up to ∠d
Step-by-step explanation:
-25 + 14 ÷ (5-3)
= -25 + 14 ÷ (2)
= - 25 + 7
= - 18
