1 = 7x=42 (divide both sides by 7)
7x/7 =42/7
x=6
2.=9y=81 (divide both sides by 9)
9y/9y= 81/9
y=9
3.= –40=8a (divide both sides by 8)
–40/8= 8a/8
a=5
4.=y divided 11=12
y=11 multiplied by 12
y= 132
5.= –15y=135( divide both sides by –15)
–15y/–15=135/–15
y= –9
6.= 17p=51(divide both sides by 17)
17p/17=51/17
p=3
7.= –65= –13w (divide both sides by 13)
–65/–13=–13w/–13
w=5
8.=y/–2=4
(cross multiply)
y/–2=4/1
4 multiplied by –2= –8
therefore:y= –8

Answer:
x = 7
Step-by-step explanation:
[tex]\frac{10}{8} = \frac{3x-6}{12}[/tex] --> Triangle Similarity Theorem
120 = 8(3x - 6) --> Cross Multiplying
120 = 24x - 48 --> Distributing the 8
24x - 48 + 48 = 120 + 48 --> Adding 48 on both sides
24x = 168 --> Simplifying
24x/24 = 168/24 --> Divide 24 on both sides
x = 7 --> Simplifying

Find the number of outcomes in the complement of the given event. Out of 246 shoes in a department store, 198 are women's shoes.
Answers
Answer:
I suppose that the event here is selecting randomly a shoe.
We know that there are 246 shoes in the store, and 198 of them are women's shoes.
Then there are 246 - 198 = 48 shoes that are not women's shoes.
This means that if the event is something like "finding randomly a women's shoe"
The complement would be "selecting randomly a shoe which is not a women's shoe"
And there will be 48 outcomes that meet this condition.

Fiona, Peter and Angad share some sweets in the ratio 5:1:2. Fiona gets 33 more sweets than Angad. How many sweets are there altogether?
Answers
1 portion=11
5x11=55
11x1=11
2x11=22
55+11+22=88
For every 5 sweets Fiona has, Peter has 1 sweet and Angad has 2 sweets.
If Fiona has 33 more, that means each of the 8 portions contains 11 sweets.
5-2 = 3
33/3 = 11
Fiona has 55 sweets.
Peter has 11 sweets.
Fiona has 22 sweets.
5x11 = 55
1x11 = 11
2x11 = 22
55+11+22 = 88 sweets in total

10. The Johnson family purchased a new television that had a 62 inch diagonal. The height of the television was 30 inches. Approximately how wide is the new television? show work
Answers
Answer:
Width = 54.3 inches
Step-by-step explanation:
We solve this question using the Pythagoras Theorem
Width² + Height² = Diagonal²
From the above question
Width= ??
Height = 30 inches
Diagonal = 62 inches
Width² + 30² = 62²
Width² = 62² - 30²
Width = √62² - 30²
Width =✓2944
Width = 54.258639865 inches
Approximately
Width = 54.3 inches
Hence, the new television was 54.3 inches wide.

Answers
Answer:
360
Step-by-step explanation:
We need to find the LCM of 18,90 and 24.
The prime factorization of 18 = 2 × 3 × 3
The prime factorization of 90 = 2 × 5×3×3
The prime factorization of 24 = 2 × 3×2×2
LCM is least common multiple.
LCM = 2 x 2 x 2 x 3 x 3 x 5
= 360
Hence, the LCM of 18,90 and 24 is 360.

Scalene triangles are

Olivia and Cody both have spinners with the color purple. Olivia determines that the probability of spinning purple on her spinner is 4 out of 12. Cody determines that the probability of spinning purple on his spinner is 3 out of 10. Which of the following statements is true?
Answers
So the answer would be B
The true statements:
A) Olivia's spinner has the highest probability of spinning purple.
What is the probability?The Probability in mathematics is the possibility of an event in time. In simple words, how many times that incident is happening in any given time interval.
Given:
Olivia and Cody both have spinners with the color purple.
Olivia determines that the probability of spinning purple on her spinner is 4 out of 12.
That means, 4/12 = 0.33
Cody determines that the probability of spinning purple on his spinner is 3 out of 10.
That means, 4/10 = 0.3
0.33 > 0.3
Therefore, Olivia's spinner has the highest probability of spinning purple.
