Answer: 35/18
Step-by-step explanation:
[tex] \frac{ \{ \frac{3}{4} - \frac{5}{2} \} }{ \{ \frac{3}{5} - \frac{3}{2} \}} = \frac{( - \frac{7}{4} )}{ (- \frac{9}{10} )} \\ \\ = \frac{7}{4} \div \frac{9}{10} [/tex]
use the reciprocal of 9/10 :
[tex] = \frac{7}{4} \times \frac{10}{9} \\ \\ = \frac{35}{18} [/tex]

[tex] \huge \sf\frac { \frac { 3 } { 4 } - \frac { 5 } { 2 } } { \frac { 3 } { 5 } - \frac { 3 } { 2 } } \\ [/tex]
The least common multiple of 4 and 2 is 4. Convert [tex]\sf\frac{3}{4} [/tex]and [tex]\sf\frac{5}{2} [/tex]to fractions with denominator 4.[tex] \huge \sf \frac{\frac{3}{4}-\frac{10}{4}}{\frac{3}{5}-\frac{3}{2}} \\ [/tex]
Because [tex]\sf\frac{3}{4} [/tex]and [tex]\sf \frac{10}{4}[/tex] have the same denominator, subtract them by subtracting their numerators.[tex] \huge \sf\frac{\frac{3-10}{4}}{\frac{3}{5}-\frac{3}{2}} \\ [/tex]
Subtract 10 from 3 to get -7.[tex] \huge \sf\frac{-\frac{7}{4}}{\frac{3}{5}-\frac{3}{2}} \\ [/tex]
The least common multiple of 5 and 2 is 10. Convert [tex]\sf\frac{3}{5}[/tex] and [tex]\sf \frac{3}{2}[/tex] to fractions with denominator 10.[tex] \huge \sf\frac{-\frac{7}{4}}{\frac{6}{10}-\frac{15}{10}} \\ [/tex]
Because [tex]\sf \frac{6}{10}[/tex] and [tex]\sf \frac{15}{10}[/tex] have the same denominator, subtract them by subtracting their numerators.[tex] \huge \sf\frac{-\frac{7}{4}}{\frac{6-15}{10}} \\ [/tex]
Subtract 15 from 6 to get -9.[tex] \huge \sf\frac{-\frac{7}{4}}{-\frac{9}{10}} \\ [/tex]
Divide [tex]\sf-\frac{7}{4}[/tex] by [tex]\sf-\frac{9}{10}[/tex] by multiplying [tex]\sf-\frac{7}{4}[/tex] by the reciprocal of [tex]\sf-\frac{9}{10}[/tex].[tex] \huge \sf-\frac{7}{4}\left(-\frac{10}{9}\right) [/tex]

Answers
Answer:
Exponential notation is a powerful way to express repeated
multiplication of the same number. Specifically, powers of 10
express very large and very small numbers in a manner which is
convenient to read, write and compare.
• For any non-zero integer a, a–m 1
m a
=
• Laws of exponents are
(a) am × an = am+n
(b) am ÷ an = am–n
(c) (am)
n = amn
(d) am × bm = (ab)
m
(e) a° = 1, where a ≠ 0
(f)

• Numbers can be expressed in expanded form by using exponents.
• Very large and very small numbers can be expressed in standard
form.
• Standard form is also called scientific notation form.
Step-by-step explanation:
Example 1 : Multiplicative inverse of 27 is
(a) 2–7 (b) 72 (c) – 27 (d) – 27
Solution : The Correct answer is (a).
Example 2 : The human body has about 100 billion cells. This number
can be written in exponential form as
(a) 10–11 (b) 1011 (c) 109 (d) 10–9

Help me with 19 and 20
19 find x
20 find y
Answers
Answer:
19) x = 48
20) y = 21
Step-by-step explanation:
19)
7x - 248 + x + 44 = 180
(because they're supplementary angles)
8x - 204 = 180
8x = 180 + 204
8x = 384
x = 48
20)
2y + 50 + 5y - 17 = 180
7y + 33 = 180
7y = 180 - 33
7y = 147
y = 21
Sarah has saved $150. She wants to double the amount she saves each month. As an incentive, Sarah’s grandma says if she saves that amount, she will give her an additional $50 each month. What are the recursive formula and first term for Sarah’s saving’s?
Answers
Answer:
A₁ = $150.
Step-by-step explanation:
We know that:
Sarah has saved $150 at the moment.
She wants to double the amount that she saves each month, so the next month she needs to save 2*$150 = $300
And if she saves the $300, then her grandma will give her another $50.
Then, if the previous month Sarah saved A, then the next month she will get the double of A plus $50, which is:
2*A + $50
Then the recursive relation is just:
Where Aₙ is the amount that she saves in the n-th month, and the first term of the sequence is the initial amount that she saved, so we have:
A₁ = $150.

5x + 2 + 5x = 11x - 11 Combine the terms on the left.
10x + 2 = 11x - 11 Add 11 to both sides

10x + 13 = 11x Subtract 10x from both sides.
13 = x

The first number in each ordered pair tells how far across the X line is to move. The second number in each ordered pair tells how far up or down the Y line is to move.

How many repeating digits are in the smallest group of repeating digits in the decimal equivalent of the fraction shown?
745/999
Answers
If x = 745/999, then
999x = 745
1000x - x = 745
This equation tells us that the fractional part of 1000x and x cancel upon subtracting. This means the block of repeating digits must be 3 digits long.
To verify this, suppose we write x = 0.yyy… , where y consists of 3 digits. Then
1000x = y.yyy…
1000x - x = y.yyy… - 0.yyy…
999x = y
x = y/999
which means y = 745.
Answer:

Javonie started a dog walking business over the summer. He walked 8 dogs and earned $160 in July.
He walked 9 dogs and earned $180 in August.
a. How much money did he earn over the summer?
b. How much did he charge per dog in July?
*Determine what you need to find.
*Set up the problem.
*Solve.
*Check.
Answers
Answer:
a) $340
b) $20
Step-by-step explanation:
a) in the summer (July and August) he earned 160 + 180 = $340
b) in July he earned 160 ÷ 8 = $ 20
Javonie earned $340 over the summer and he charged $20 per dog in July.
The amount of money he earned over the summer is the sum of the money he earned in July and the sum of the money he earned in August
Total amount earned in the summer = amount earned in July + amount earned in August
$160 + $180 = $340
The amount he charged per dog in July can be determined by dividing the total amount earned in July by the total number of dogs he walked.
Amount charged per dog = amount earned in July / total dogs worked
$160 / 8 = $20

you have piano lessons every 7 day and tuba lessons every 3 days today you have both lessons.
A. In how many days wil you have both lesson on the same day agian?
B. Not counting today or the day when you have the same lesson again, How many piano lesson will you have in between? Have many tuba lesson will you have in between?
Answers
Answer:
A.21 days
B.2, 6
Step-by-step explanation:
(a) In 21 days we will have both lessons on the same day again.
(b) Between each occurrence of having both lessons on the same day again, you will have 2 piano lessons and 6 tuba lessons.
a.
To find out when we will have both lessons on the same day again, we need to find the least common multiple (LCM) of 7 and 3.
The LCM of 7 and 3 is 21. This means that every 21 days, our piano and tuba lessons will align again.
b. Between each occurrence of having both lessons on the same day, you have 21 days. During these 21 days, you will have:
21 / 7 - 1 = 2 piano lessons.
21 / 3 - 1 = 6 tuba lessons.
So, between each occurrence of having both lessons on the same day again, we will have 2 piano lessons and 6 tuba lessons.

1/6x-1/8=11/12
Answers
Answer:
6 and 1/4
Step-by-step explanation:
1/6 x - 1/8 = 11/12
First, let's find the least common denominator (24) to make these fractions manageable to work with: 4/24 x - 3/24 = 22/24.
Next, add 3/24 to both sides: 4/24 x = 25/24.
We can cancel out the denominators at this point to get: 4x=25.
Divide both side by 4, and x = 25/4 = 6 and 1/4 or 6.25
