Answer
7. 30
8. 54
Step-by-step explanation:
For 7 do 2x+3x=90 because it is a right angle
then solve for x and get 15
to get the angle you are looking for multiply 2 by 15
and get the answer 30
For 8 to find the value of x you would need to...
add (4x+6) + (11x-6)= 180 because 180 is a straight angle.
Then simply solve for x and get 15x=180 which equals 12
The to get the angle you plug it in to (4x+6) and get the answer 54
Answer:
-2/4 = w
Step-by-step explanation:
4w + 2 when you isolate the variable, you subtract the 2, then you have to divide by 4 so that would give you -2/4 = w.
There are 12 white ribbons, 15 red ribbons, and 11 blue ribbons.
38=(w-1)+(w+3)+w
combine like terms
38=2+3w
subtract 2 from both sides
36=3w
divide 3 on both sides
12=w
w-1=b
12-1=b
11=b
w+3=r
12+3=r
15=r
Check Your Work
w+r+b=38
15+11+12=38
38=38
