The expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.
What is an expression?It is defined as the combination of constants and variables with mathematical operators.
We have an expression:
= 2(14x - 3y + 28x + 12.2 - 5y - 17.5)
= 28x - 6y + 56x + 24.4 - 10y - 35
Adding like terms
= 84x - 16y -10.6
Thus, the expression 2(14x - 3y + 28x + 12.2 - 5y - 17.5) is equivalent to the expression 84x - 16y -10.6 option (A) is correct.

Please help me with this. 3 pieces of gum cost 25 cents. How many pieces of gum can you buy for $1.00?
Answer:
12 pieces
Step-by-step explanation:
There are four 25 cents in a dollar, as a dollar is 100 cents and 100 divided by 25 is four. So as 3 pieces cost 25 cents, multiply 3 by 4 which is 12.
12 pieces of gum would cause $1.00
Answer:
You can get 12 pieces of gum.
Step-by-step explanation:
3 pieces is 25, right? so now to make a dollar you can have four of 25 cents, so multiply, 3x4. You get 12. so you can buy 12 pieces of gum.

11-10x=5-4x
answer choices
A. Subtract 5 from the left side
B. Add 10x to both sides
C. Subtract 11 from the right side
D. Subtract 4x from both sides
Answer:
B.
Step-by-step explanation:
remember, solving this means to get the variable alone on one side (it does not matter which side), and everything else on the other side.
but whatever changes we do (except for just completing local operations that were already there), we always have to do them to both sides to keep the equality alive. if we introduce a change of quantity on one side only, we break the equality, and we will not get a valid result anymore.
A. subtract 5 from the left side : no, it changes only the left side. the equality is broken.
B. add 10x to both sides. yes, it applies the change to both sides and will bring all terms of x to one side. perfect.
C. subtract 11 from the right side. no, it changes only the right side. the equality is broken.
D. subtract 4x from both sides. no. it does change both sides and keeps the equality, true, but it does not help us in solving the equation. it still keeps a mixture of x terms and constant terms on both sides. nothing changes in the structure.

Given the equation y − 4 = three fourths (x + 8) in point-slope form, identify the equation of the same line in standard form.
Answer:
3x-4y=-40
Explanation
y-4=3/4(x+8)
distribute the 3/4
y-4= 3/4x + 6
add 4
y= 3/4x+10
then change to standard form
3x-4y=-40

A family has a hybrid car that gets 40 miles per gallon (mpg) and a pickup truck that gets 17 mpg. They drive at least 500 miles per week using both vehicles but don't want to use more than 20 gallons of gas. Make a recommendation for using each vehicle. Part A Write an expression that represents the total amount of gasoline used. Then write an inequality to show the maximum amount of gasoline that the family wants to use. Define the variables and list any constraints on the variables.
Answer:
[tex]Z=x+y[/tex]
[tex]x+y<20[/tex]
Step-by-step explanation:
Let the gallons of fuel used in the hybrid per week car be [tex]x[/tex] and [tex]y[/tex] be the number of gallons used in the pickup truck per week.
Number of miles driven using both vehicles is at least 500 per week. The inequality that represents the number of miles driven is.
[tex]40x+17y\geq 500[/tex]
The expression of total amount of fuel used would be [tex]Z=x+y[/tex].
Now the sum of the fuels used in both the cars is more than 20 gallons per week. The inequality that represents the total amount of gasoline used is
[tex]x+y<20[/tex]

Answer:
D. m<RST = 2(m<TSU)
Step-by-step explanation:
Given that m<RST = 76°, m<RSU = 48°, and m<TSU = 38°, this implies that:
SU is an angle bisector of angle RST. Thus,
m<RST is twice the measure of <RSU or <TSU.
Therefore, the only option that is correct is:
D. m<RST = 2(m<TSU)

Tell whether the following function is linear. If so; graph the function: 2x + 3y = 5.
Long division was used here to divide the polynomial function p(x) = x3 + 7x2 - 20x -110 by (x - 5) and to divide it by (x + 5).
Using the information given above, p(-5) =
The value of the polynomial function at p(-5) is 40.
A polynomial is an expression that solely uses the operations of addition, subtraction, multiplication, and positive-integer powers of variables and is made up of indeterminates (also known as coefficients) and these operations.
In an equation such as the cubic equation, quadratic equation, etc., a polynomial function is a function that only uses positive integer powers or only positive integer exponents of a variable.A polynomial expression is one that can be created from variables and other constants and symbols by adding, multiplying, and raising it to a non-negative integer power. The constants, which represent mathematical objects that can be added to and multiplied, are often numbers, but they can also be any expression that does not contain the indeterminates.The given polynomial function is:
p(x) = x³ + 7x² - 20x -110
or, p(-5) = (-5)³ + 7(-5)² - 20(-5) -110
or, p(-5) = -125 + 175 + 100 - 110
or, p(-5) = 40
So the value of the polynomial function is 40.

Step-by-step explanation:
Step 1: Set up equation
m∠LMN and m∠NMP must add up to m∠LMP
(2x - 1)° + (5x + 3)° = 107°

The level of the tide in a harbor changes from 9 1/4 to 4 1/2 above sea level over a period of 3 1/4 h. Whatbis the rate of change in the tide level over this period of time?
Answer:
The answer should be -19/13 per hour. I think, I'm not completely sure.
Step-by-step explanation:
Find the difference of 9 1/4 and 4 1/2
divide by 3 1/4
simplify
4 1/2 - 9 1/4 = -19/4
-19/4 divided by 13/4 = -76/52
-76/52 = -38/26 = -19/13
So the answer should be -19/13 per hour.
The requried rate of change in the tide level over this period of time is 19/13h.
What is the rate of change?Rate of change is defined as the change in value with rest to the time is called rate of change.
To find the rate of change, we need to divide the change in the tide level by the time elapsed:
Change in tide level = 37/4 - 9/2 = 37 - 18/4 = 19/4
Time elapsed = 13/4 h
Rate of change = Change in tide level ÷ Time elapsed
= 19/4 ÷ 13/4
= 19/13 h
So, the rate of change in the tide level over this period of time is 19/13h.
