First, divide -5 on both sides:

(x + 7) < -2

Then subtract 7 on both sides:

x < -9

How do I do this I really don't understand anything here
Lera25 [3.4K]

The red arrows show that the lines are parallel, but using the stuff given you can make an equation.
its hard to explain without drawing but starting from the 60 if you can make a Z you will get alternate angles and that mean that the given equation MUST be equal to 60. So,

8x-4=60

8x=60+4

8x=64

x=64/8

x=8 (is your answer)

hope you understand

How to evaluate this f (x) = -x^+1 for x =-3
sukhopar [10]
Just plug in -3 for x. So it will be -(-3)^+ 1
Which is 3^+1.
I'm confused by your ^ sign I'm not sure if this is supposed to be squared or not...? But just solve/simplify the equation.
Hope this helps!

Sharon has a new beaded necklace. 72 out of the 80 beads on the necklace are blue. What
erma4kov [3.2K]

Answer:

Sharon bought a necklace with 90% blue beads.

Step-by-step explanation:

We are given that Sharon's necklace has 80 beads. We are also given that of those 80 beads, 72 of them are blue.

Therefore, we can set up a ratio of blue beads to total beads in order to find out the relationship.

\displaystyle \frac{72}{80}=\frac{36}{40}=\frac{18}{20}=\frac{9}{10}

Then, using the fraction we receive as a result, we can convert this to a decimal.

\displaystyle \frac{9}{10} = 0.9

After we complete this calculation, we can multiply our decimal by 100 in order to obtain the relationship in percentage form.

0.9 \times 100 = 90\%

Of the 80 beads, 90% were blue beads.
