7. We know that they must all add up together to get 90 degrees because of the symbol show the right angle.
We can use this to form and solve an equation:
2x +1x + 30 = 90
3x+30 = 90 (add the x's together)
3x = 60 (subtract both sides by 30 to get the x's alone)
x =20 (divide by 3 to get what 1x is equal to)
(The next question is very similar)
8. To solve this, we need to know what all the x's together are equal to.
Since angles on a straight line add up to 180 degrees -we can make an equation:
4x+x+30 = 180
5x + 30 +180 (add all the x's together)
5x = 150 (subtract both sides by 30 to get what 5x is equal to)
x = 30 (divide by 5 to get what just 1x is)

502&153
Step-by-step explanation:
Answer:

Step-by-step explanation:
According to the given information,
- Pairs of black pants = 2
- Pair of brown pants = 1
- Pairs of blue pants = 2
Then, total pairs of pants = 2 + 1 + 2 = 5
Similarly,
- Pink T-shirts = 2
- Blue T-shirts = 2
Then, total number of T-shirts = 4
This gives us the total nunber of clothing articles with Jenny, i.e.,
Total pairs of pants + Total number of T-shirts
= 5 + 4
= 9
Now, the probability of pulling out a pair of black pants & a blue T-shirt will be:
Total pairs of black pants + Total nunber of blue T-shirts/Total clothing articles
= 2 + 2 / 9
= 4/9

Answer:
Step-by-step explanation:
the circumference of the circle, C=2*3.14*r
C=3.14*d
C=3.14*12=37.68
Im pretty sure its
m=/0 because when m is 0 then f(x) does not depend on the value of x.
Hope this helped!
