Answer:
20
Step-by-step explanation:
1.4-28/x = 0
bring 1.4 to the right hand side
-28/x = -1.4
bring the x to the right hand side
-28 = -1.4x
switch the positions of -28 and -1.4x
-1.4x = -28
divide -28 by -1.4
x = -28/-1.4
x = 20
If a = -2, b= -5, and c = -6, then a - b + c =
(Hint: NOT -1 or -13)
Answer:
-3
Step-by-step explanation:
= -2-(-5)+-6
= -2-(-5)-6
= -2--5-6
= -2+5-6
= -3

simplify 5(a+6)−a+7a−18
Answer:
11a + 12
Step-by-step explanation:
For this problem, we will simply use the distributive property both forwards to gather all of the like terms, and then backward to simplify the like terms.
5 ( a + 6 ) - a + 7a - 18
= 5a + 30 - a + 7a - 18
= 5a - a + 7a + 30 - 18
= a ( 5 + -1 + 7 ) + 30 - 18
= a ( 4 + 7 ) + 12
= a ( 11 ) + 12
= 11a + 12
Hence, the simplification for 5(a+6)-a+7a-18 is 11a + 12.
Cheers.
Answer: 11a+12

The siding of a house is 2250 square feet. The siding needs two coats of paint. One quart costs $18 and covers 80 square feet. One gallon costs $29 and covers 320 square feet. What is the minimum cost of the paint needed to complete the job? How much paint is left over?
Answer:
Minimum cost needed = $221
Remaining quart paint = 7/8
Step-by-step explanation:
Let
x = number of 1 gallon paints
y = number of 1 quart paints
1 gallon covers 320 square feet
1 quart covers 80 square feet
Number of gallons paint needed = Total siding of the house / 320 square feet
= 2250 / 320
= 7.0312
Approximately to the nearest whole number
Number of gallons paint needed = 7 gallons
Total siding of the house covered by gallons = 7 gallons × 320 square feet
= 2,240 square feet
Siding of the house remaining = Total siding - Siding covered
= 2,250 - 2,240
= 10 square feet
1 quart covers 80 feet
Therefore, 1 quart will cover the remaining 10 square feet
A. The minimum cost of the paint needed to complete the job
Total cost = (Price of gallons × Quantity of gallons needed) + (price of quart × Quantity of quart needed)
= (29 × 7) + (18 × 1)
= 203 + 18
= $221
Minimum cost needed = $221
B. How much paint is left over
Recall
1 quart covers 80 square feet
And remaining siding to be covered = 10 square feet
That is,
10/80 = 1/8 of a quart paint used
Remaining quart paint = 1 - 1/8
= 7/8 quart paint
Answer:
no
Step-by-step explanation:
no
What is the sum of the following equatiioin? 10x+20y+5x=?
Answer:
15x + 20y
Step-by-step explanation:
First, we need to combine like terms,
10x + 20y + 5x
15x + 20y
Since x and y are different variables, we cannot combine them, meaning that the answer is,
15x + 20y

The depths of two scuba divers exploring a living coral reef are shown. a. Write an integer for the position of each diver relative to sea level. The position of the diver on the left relative to sea level is feet. The position of the diver on the right relative to sea level is feet. b. Which integer in part (a) is greater? is greater. c. Which integer in part (a) has the greater absolute value? has the greater absolute value.
Answer:
a: left = 14 feet
right = 18 feet
b: 18 is significant
c: absolute value is 18
Step-by-step explanation:
a)
The position of the diver on the left relative to the sea level is 14 feet.
The position of a diver on the right to sea level is 18 feet.
b)
integer 18 in part (a) is more significant.
c)
Absolute value is the distance and the zero on the number line.
Absolute value of |18| = 18
Absolute value of |14| = 14
Hence the most excellent absolute value is 18.

Find the inverse of the function f(x) = x3 + 5
Answer:
[tex]{f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]Step-by-step explanation:
[tex]f(x) = {x}^{3} + 5[/tex]
To find the inverse of f (x) , equate f(x) to y
That's
y = f(x)
[tex]y = {x}^{3} + 5[/tex]
Next interchange the terms
That's x becomes y and y becomes x
[tex]x = {y}^{3} + 5[/tex]
Next solve for y
Send 5 to the other side of the equation
[tex] {y}^{3} = x - 5[/tex]
Find the cube root of both sides to make y stand alone
That's
[tex] \sqrt[3]{ {y}^{3} } = \sqrt[3]{x - 5} [/tex]
[tex]y = \sqrt[3]{x - 5} [/tex]
We have the final answer as
[tex] {f}^{ - 1} (x) = \sqrt[3]{x - 5} [/tex]

Answer:
87
Step-by-step explanation:
If the dog ate half of the collection, he would have 92 but the question asks how many he started with so you would subtract 92-5 to get 87. Hope this helped.
There is a math student in distress over Algebra 2. Pi-Guy quickly travels to go tutor the student. Here is Pi-Guy’s movement to travel to the student: he flips downward, flies 7 units to the right, and then down 8 units. Write the equation f(x) to show the movements that Pi-Guy makes from his original location (the parent function from Part 1). You do not need the specific type of function, just write in terms of f(x).
Answer:
See below explanation
Step-by-step explanation:
So you just have to move the heroine around the map. Draw out a map with a village and the hero-guy will go save the college student.
Equational path (you have to make sure f(x) is in the pathological way because that is part of the instructions for this problem) : g(y) = a^8 + 7(f(x)
This shows that the guy went 8 miles and then 7 in the function.
To show the flip that the guy does, just turn the equation around: f(x)*7 +a^8 = g(y)
Answer:
f(x)*7 +a^8 = g(y)

I NEED HELP ASAP!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! I WILL GIVE BRAINLIST WHOEVER COMES FIRST Evaluate the expression if x = 9 and y = 2. 5x + y
Answer:
To evaluate an algebraic expression, you have to substitute a number for each variable and perform the arithmetic operations. In the example above, the variable x is equal to 6 since 6 + 6 = 12. If we know the value of our variables, we can replace the variables with their values and then evaluate the expression.
