Simplify (4/5)^-2 . Show your work!
Answer:
[tex]\frac{25}{16}[/tex]
Step-by-step explanation:
Apply exponent rule: [tex]x^{-y}=\frac{1}{x^y}[/tex]
[tex](\frac{4}{5}) ^{-2}=\frac{1}{\left(\frac{4}{5}\right)^2}=\frac{1}{\frac{16}{25}}=\frac{25}{16}[/tex]

14 - ( 9t - 2 ) < - t + 30 Anyone know multistep equations
Answer:
t > -7/4
Step-by-step explanation:
Step 1: Write out inequality
14 - (9t - 2) < -t + 30
Step 2: Distribute
14 - 9t + 2 < -t + 30
Step 3: Combine like terms
-9t + 16 < -t + 30
Step 4: Add 9t to both sides
16 < 8t + 30
Step 5: Subtract 30 on both sides
-14 < 8t
Step 6: Divide both sides by 8
-7/4 < t
Step 7: Rewrite
t > -7/4
Ms. Garcia's seventh grade class is collecting aluminum cans to buy new board games. They receive $0.35 for each pound of cans they collect. What is the minimum number of pounds of aluminum cans they need to collect in order to purchase a board game that costs $27.20? HELP PLEASE

Older kittens need wet cat food which costs $1.50 per can. Part A: Write an algebraic expression to describe how much the humane society will spend preparing for kitten season. Part B: How much money (before tax) will the humane society spend if they buy 30 bottles of kitten formula and 120 cans of wet cat food? Part C: If you add a 7% sales tax to the purchase of bottles of kitten formula and cans of wet cat food, write a new expression accounting for sales tax.
Answer:
A. 3.99b+1.50c
B. 119.70+180= $299.70
C. (3.99b×0.07)+(1.50c×0.07)

0.5x -2 = 1.5x + 0.15
Answer: x=−2.15
Step-by-step explanation : Alright Let's solve your equation step-by-step.
0.5x−2=1.5x+0.15
Step 1: Subtract 1.5x from both sides.
0.5x−2−1.5x=1.5x+0.15−1.5x
−x−2=0.15
Step 2: Add 2 to both sides.
−x−2+2=0.15+2
−x=2.15
Step 3: Divide both sides by -1.
−x
−1
=
2.15

x=−2.15 hope this helped!- Alex

18= 5m + 3 .. what would b m?
Answer:
m=3
Step-by-step explanation:
Move all terms that don't contain m to the right side and solve.
Answer:
m=3
Step-by-step explanation:
Simplifying
18 = 5m + 3
Reorder the terms:
18 = 3 + 5m
Solving
18 = 3 + 5m
Solving for variable 'm'.
Move all terms containing m to the left, all other terms to the right.
Add '-5m' to each side of the equation.
18 + -5m = 3 + 5m + -5m
Combine like terms: 5m + -5m = 0
18 + -5m = 3 + 0
18 + -5m = 3
Add '-18' to each side of the equation.
18 + -18 + -5m = 3 + -18
Combine like terms: 18 + -18 = 0
0 + -5m = 3 + -18
-5m = 3 + -18
Combine like terms: 3 + -18 = -15
-5m = -15
Divide each side by '-5'.
m = 3
Simplifying
m = 3
hope this helps

The mathematical expression is _ NOTE: Make sure that there are NO SPACES between the numbers and the operations. The number is x. Write the mathematical expression for: Five more than the product of the number and six.
Answer:
5x+x=6
Step-by-step explanation:
x: -2(x + 3) = -2(x + 1) - 4. ( 1 point)
Answer:
This is true for all x
Step-by-step explanation:
-2(x + 3) = -2(x + 1) - 4
Distribute
-2x-6 = -2x-2 -4
Combine like terms
-2x-6 = -2x-6
Add 2x to each side
-2x+2x-6 = -2x+2x-6
-6 = -6
This is always true so there are infinite values
This is true for all x

Answer:
Question continuation
"2. A $480,000 note payable requires 9.1% annual interest, or $3,640, to be paid at the 20th day of each month. The interest was last paid on April 20 and the next payment is due on May 20. As of April 30, $1,213 of interest expense has accrued.
3. Total weekly salaries expense for all employees is $9,000. This amount is paid at the end of the day on Friday of each five-day workweek. April 30 falls on a Tuesday, which means that the employees had worked two days since the last payday. The next payday is May 3. The above three separate situations require adjusting journal entries to prepare financial statements as of April 30. For each situation, present both the April 30 adjusting entry and the subsequent entry during May to record the payment of the accrued expenses. (Use 360 days a year. Do not round intermediate calculations.)"
Solution:
No Type Date Account Debit Credit
1 Adjusting Apr 30 Legal Expenses $3,500
Accounts Payable $3,500
(To record legal expenses)
Subsequent May 12 Accounts Payable $3,500
Cash $3,500

Postitive numbers
Step-by-step explanation:
Identify the relationship (complementary, linear pair/supplementary, or vertical) and find the value of x in the image below.
Answer:
Complementary and x = 24°
Step-by-step explanation:
→ Recognise that angles on a straight line add up to 180°
x + 8° + 148° = 180°
→ Simplify equation
x + 156° = 180°
→ Minus 156° from both sides of the equation to isolate x
x = 24°
the scale for a map to actual distance is 2 cm to a 100 miles the actual distance on the map be between Los Angeles and Las Vegas is 5.4 centimeters what is the actual distance in miles between Los Angeles and Las Vegas.Show your work.
Given :
The scale for a map to actual distance is 2 cm to a 100 miles.
To Find :
He actual distance on the map be between Los Angeles and Las Vegas is 5.4 centimetres what is the actual distance in miles between Los Angeles and Las Vegas.
Solution :
2 cm of map shows 100 miles of actual distance.
So, 1 cm of map shows 50 miles of actual distance.
Now, 5.4 cm of map will show :
[tex]D=5.4\times 50\ miles\\\\D=270\ miles[/tex]

The value of y is directly proportional to the value of x. If y = 91 when x = 13, what is the value of y when x =
12?
Answer:
y= 84
Step-by-step explanation:
y = kx
where k is the constant
k = y/x = 91/13 = 7
the value of Y when x= 12
y = kx =7(12)
y =84
what is the sum of a rational numbers?
Answer:
Step-by-step explanation:
So, adding two rationals is the same as adding two such fractions, which will result in another fraction of this same form since integers are closed under addition and multiplication. Thus, adding two rational numbers produces another rational number.
