what is the answer to x - 8 < -2

Answers

Answer:

X < 6

Step-by-step explanation:

Add 8 to both sides

x < 6

Answer:

X<6

Step-by-step explanation:

x-8<-2

So first off, you want to get X by itself. To do that you have to do the opposite of what the number is. If the number is negative you add it. If the number is positive, you subtract it. What you do on one side, you do on both.

x-8<-2

+8      +8

X<-2+8

both of those equations that are in the system are lines

first line it has a y-intercept at (0, -4) and a slope -1/2 so you can use that to

find another point ( 2 ,-5)

Since the equation has ≥ DRAW a solid line trough points (0, -4) and (2,-5)

Now highligt above the line since (0,0) cheks for the equation

second line goes troughh the points  (0,1) because of y-intercept and point (1,2) because the slope is m=1

draw a solid line trough those points and highlight under the line

the intersection of the 2 highlighted ares is your solution

A random two digit number (10-99) is drawn. Find each probability

1. p(32)
2. p(odd number)
3. p(a multiple of 5)

My teacher gave an assignment on this and didn't even teach how to do it.​

Answers

Given that two digit numbers are used and one digit is drawn randomly.

Sample space = {10,11,...99}

n(S) = 90

32 is only one number favorable

Hence P(32) = 1/90

----------------------------

Odd numbers are exactly 45.

Hence prob (odd number) = 45/90 = 1/2

-------------------------------------

Multiples of 5 are 10,15,.....95

There are exactly 18 numbers.

Hence P(a multiple of 5) = 18/90 =1/5

Victoria uses
3/16
cup of flavored syrup to make an Italian soda. She has 2 cups of flavored syrup left. How many Italian sodas can she make?
A.
9 3/8
B.

10 2/3
C.

11 1/4
D.

12 1/2

Answers

Answer:

B. or 10 2/3

Step-by-step explanation: Because if she had only 2 cups left then 1 cup can make 5 drinks so 10 then the rest would be a fraction.

She can make 32/3 of Italian sodas with 2 cups of flavored syrup.

What is a fraction?

A fraction is written in the form of p/q, where q ≠ 0.

Fractions are of two types they are proper fractions in which the numerator is smaller than the denominator and improper fractions where the numerator is greater than the denominator.

Given, Victoria uses 3/16 cups of flavored syrup to make an Italian soda.

Assume that 3/16th of x is 1.

∴ (3/16)x = 1.

3x/16 = 1.

3x = 16.

x = 16/3,

Now from 2 cups of flavored syrup, we can make 2x of  Italian soda.

Which is (16×2)/3.

= 32/3
