Hello Kiddo. 

This question is a bit confusing to me, but I think I grasped the concept. 
1. x best represents Sarah's mom's age. 
2. x - 24 best represents Sarah's mom's age minus how much younger Sarah is than her mom. 
3. The expression would look a little like this:
2x-24 = 68
    + 24  +24
2x = 92 
/2     /2
x = 46.

Which means, Sarah is 22 and her mom is 46 years of age. 
If you need more clarification, I'd be more than happy to elaborate further.

Alenkinab [10]

Answer:

E\ n\ F = \{1, 5, 6,7\}

F\ n\ G =\{9\}

F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}

P(F\ U\ G) = \frac{3}{4}

Step-by-step explanation:

Given

S = \{1,2,3,4, 5,6,7,8, 9, 10, 11, 12\}

E = \{1,2, 3, 4, 5, 6,7\}

F =\{1,5,6, 7, 8,9\}

G = \{9,10, 11, 12\}

H = \{2, 3, 4\}

Solving (5): E and F

Sets of E and F = E n F

E\ n\ F = \{1,2, 3, 4, 5, 6,7\}\ n\ \{1,5,6, 7, 8,9\}

List out common elements

E\ n\ F = \{1, 5, 6,7\}

<em>They are not mutually exclusive because </em>n(E\ n\ F) \neq 0<em />

Solving (6): F and G

Sets of F and G = F n G

F\ n\ G =\{1,5,6, 7, 8,9\}\ n\ \{9,10, 11, 12\}

List out common elements

F\ n\ G =\{9\}

<em>They are not mutually exclusive because </em>n(F\ n\ G) \neq 0<em />

Solving (7): F or G and P(F or G)

Sets of F or G = F U G

F\ U\ G =\{1,5,6, 7, 8,9\}\ U\ \{9,10, 11, 12\}

List all elements without repetition

F\ U\ G =\{1,5,6, 7, 8,9,10, 11, 12\}

Solving P(F U G)

P(F\ U\ G) = \frac{n(F\ U\ G)}{n(S)}

n(F\ U\ G) = 9

n(S) = 12

Hence;

P(F\ U\ G) = \frac{9}{12}

Divide by 3

P(F\ U\ G) = \frac{3}{4}

Solve for the value of s
lina2011 [118]

The two angles are vertical angles, which mean they are the same.

6s-2 = 94

Add 2 to both sides:

6s = 96

Divide both sides by 6:

S = 96/6

S = 16

3. A vehicle uses 15 gallons of gasoline to travel 13 miles. At this rate, how many miles can the
Tems11 [23]
1. Start by identifying what the question wants so we are looking for miles per 1 gallon.
2. Set up a statement. When the word “per” is being used it relates to a fraction or a ratio. In this question we need to find how many miles a single gallon will give us. So set it up as miles/gallons
3. Plug in your numbers. Now our statement is 13 miles/15 gallons
4. Calculate. So do 13/15 which equals 0.86 miles per 1 gallon.
Tip: always add in words into your calculations. Mainly the units you are using so you can quickly look and know what the units will be. This will help you in upper placement math as well
