Answer:
You are 34 years old
Step-by-step explanation:
Because, 34-17=17
17 is half of 34.
2x+20=y
y-17=0.5y
+17 +17
y=0.5y+17
2(0.5y+17)+20=0.5y+17
y+34+20=0.5y+17
y+54=0.5y+17
y=34
Answer: x = -5
Step-by-step explanation:
-8 (x + 5) = -3x - 7 + x - 3
First, we use distributive property
-8x - 40 = -3x - 7 + x - 3
Then, we combine like terms.
-3x + x = -2x
-7 + -3 = -10
-8x - 40 = -2x - 10
Add 10 to each side
-8x - 30 = -2x
Add 8x to each side
-30 = 6x
Divide each side by 6
-5 = x
Answer:
139
Step-by-step explanation:
first you need to find the x:
180= 8x + 51 + 6x - 25
180 - 51 +25 = 8x + 6x
154 = 14x
154/14 = x = 11
then you have to work out AOB:
8x +51
8(11) +51
88+51 = AOB = 139
to check your work, workout angle BOC and add both. angles together to check if you get 180:
BOC= 6x - 25
6(11) - 25
66 - 25 = 41
To check:
BOC + AOB = 180
41 +139 = 180
180 = 180
Hope this helps!
Divide the numerator by the denominator and any remaining values go back above the denominator.
Example:
17 / 4 is an improper fraction. To turn it into a proper fraction we do 17 divided by 4.
17 / 4 is 4 with a remainder of 4. So we put the 4 on the outside and the 1 back above the denominator, which is 4.
It ends up looking like this:
