Answer:
70 and 110
Step-by-step explanation:
The two angles add to 180 degrees since they form a straight line
2x+10 +3x+20 =180
5x+30 = 180
Subtract 30 from each side
5x+30-30 =180-30
5x = 150
Divide by 5
5x/5 =180/5
x = 30
The left angle is 2x+10 = 2*30+10 = 60+10 =70
The right angle is 3x+20 = 3*30 +20 = 90+20 = 110
Answer:
Step-by-step explanation:
Work to isolate x on one side of the inequality:
Therefore the answer is all x values larger than or equal to -30
Answer:
We can rewrite this problem as:What is 38% of 288?
"Percent" or "%" means "out of 100" or "per 100", Therefore 38% can be written as
38
/100
When dealing with percents the word "of" means "times" or "to multiply".
Finally, lets call the number of pictures we are looking for "p".
Putting this altogether we can write this equation and solve for p while keeping the equation balanced:
p
=
38
/100
×
288
p
=
10944
/100
p
=
109

Answer:
x = 15
Step-by-step explanation:
3x - y = 30
Let y = 15
3x - 15 = 30
Add 15 to each side
3x-15+15 = 30+15
3x= 45
Divide each side by 3
3x/3=45/3
x = 15
is there a picture? if there is I cant see it
