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
6x=5x+22 simplify the answer.
Answer:
x=22
Step-by-step explanation:
6x-5x=22
x=22
Answer:
Step-by-step explanation:
6x -5x =1
so,
1x(or just x) =22
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

Help me solve? Thank you! (Answers included in screenshot
Answer:
C
Step-by-step explanation:
It needs to be an "or" inequality because it is one or the other, not both. The reason C is correct is because the number needs to be between 4 and 6 or 8 and 10, so greater than the former but still less than the latter.
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]

what is the measure of W in the figure
In angle A we have supplementary angles, that is
130 + X = 180
X = 180 - 130
X = 50
From the properties of the angles of a triangle - refer to attached,
W = X + 105
as X = 50 - already calculated above, then
W = 50 + 105
W = 155Write the expression that represents this phrase: 5 less than z
Answer:
5-z
Step-by-step explanation:
5 less then z
Less then: subtraction

Use formulas d=rt. find t for r=48.3 m/h and d = 545.79 m.
(A) 26,362 h
(B) 497.49 h
(C) 0.09 h
(D) 11.3 h
Answer:
11.3
Step-by-step explanation:
Just plug in the known variables.
d = rt
d = 545.79
r = 48.3
545.79 = 48.3t
you need to get T alone
so divide
the end answer is 11.3

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]
Therefore, distance between Los Angeles and Las Vegas is 270 miles.
Hence, this is the required solution.

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
cx=dr, for x, i need help
cx = dr, for x
Divide both sides by c
x = dr / c

The local humane society is restocking on cat food to prepare for kitten season. Very young kittens need kitten formula which costs $3.99 per bottle. 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)
