1.5 is the answer to your question
Answer:
Step-by-step explanation:
I'm not sure if the right side is or , so I'll provide an answer for both:
Answer:
First angle = 30°
Second angle = 60°
Third angle = 90°
Step-by-step explanation:
x + y + z = 180
y + z = 5x
z = y + 30
then:
y + (y+30) = 5x
2y + 30 = 5x
x = (2y+30)/5
then:
x + y + z = 180
{(2y+30)/5} + y + y+30 = 180
{(2y+30)/5} + 2y + 30 = 180
{(2y+30)/5} = 180 - 30 - 2y
{(2y+30)/5} = 150 - 2y
2y+30 = 5(150-2y)
2y+30 = 5*150 + 5*-2y
2y+30 = 750 - 10y
2y + 10y = 750 - 30
12y = 720
y = 720/12
y = 60°
x = (2y+30)/5
x = (2*60 + 30)/5
x = (120+30)/5
x = 150/5
x = 30°
z = y + 30
z = 60 + 30
z = 90°
Check:
x + y + z = 180°
30° + 60° + 90° = 180°
Answer: There are n = a/7 pretzels into each bag.
Step-by-step explanation:
The options are missing, but ill try to explain it anyways.
Suppose that Sydney has pretzels, where a is an integer number.
If she puts the same number of pretzels into 7 bags. then we must divide an into 7 equal parts, then the amount of pretzels that go into each bag is
n = a/7
The cost of the slice of pizza is $1.00. this is because 3.50 - 2.50 is 1.00.
hope it helps :)
