Answer:
70°
Step-by-step explanation:
The triangles have the same angles take 180-59-61
Answer:
Step-by-step explanation:
m + j + s = 37
j = 2s......s = j/2 or 1/2j
m = j + 2
(j + 2) + j + (1/2j) = 37
2j + 1/2j = 37 - 2
2j + 1/2j = 35....multiply everything by 2 to get rid of the fraction
4j + j = 70
5j = 70
j = 70/5
j = 14 < ==== Jan is 14
m = j + 2
m = 14 + 2
m = 16 <==== marcia is 16
s = 1/2j
s = 1/2(14)
s = 14/2
s = 7 <==== sydney is 7
Answer:
20%
Step-by-step explanation:
Option B is correct option.
Step-by-step explanation:
We need to solve the inequality: 7 − 9x − (x + 12) less than or equal to 25

Solving:



Add 5 on both sides:


Divide both sides by -10 and reverse the inequality:

The number line is shown in figure attached.
Option A is correct.
Option B is incorrect because x cannot be less than -3
Option C is correct because −3 less than or equal to x is -3 ≤ can be written as: x≥-3
Option D is correct because when x is greater than or equal to the circle is closed and greater values are on right side of the number line.
So, Option B is correct.
