Which phrase can be represented by an equation? twice as much as a number 12 less than a number half of a number is 15 the difference of 20 and a number
Answer:
Half of a number is 15
Step-by-step explanation:
First of all, add commas between each option so it's easier to read I had a hard time figuring out what the options were because of this.
An equation is a statement that the values of two mathematical expressions are equal. An expression is a collection of symbols that jointly express a quantity. This means there has to be an equal sign when the phrases are put into numerical form.
Twice as much as a number: 2X
12 less than a number: X - 12
Half of a number is 15: X/2 = 15
The difference of 20 and a number: 20 - X
As you can see, only one of these phrases is an equation by definition, and that is X/2 = 15, or half of a number is 15. That's because it's the only one that values two expressions as equal.

A user car dealer brought a car for $12,000 and wants to sell it at a 15% profit. How much should he sell the car for?
Answer:
$13,800
Step-by-step explanation:
She sells the car for 115% of the value of the car, because she wants a 15% profit. 115% of 12000 is the same as 12000*1.15, since 115% is eqaul to 1.15. 12000*1.15 = 13800

Which equation models the statement shown? y varies directly with x and =25 y = 25 when =5 x = 5 .
Answer:
The value of y is 125 when x=25.
Step-by-step explanation:
It is given that y varies directly as x. It means y is proportional to x.
Where k is constant of proportionality.
It is given that y=25 when x=5. Put x=5 and y=25 in the above equation to find the value of k.
Divide both sides by 5.
The value of k is 5.
The relation between x and y is defined by the equation
Put x=25 in the above equation.
Therefore the value of y is 125 when x=25.
What is the force that always opposes (or works against) motion called?
please help quickly.
Answer:
x = 2, y = 5
Step-by-step explanation:
Given the 2 equations
y = - 2x + 9 → (1)
y = 4x - 3 → (2)
Substitute y = 4x - 3 into (1)
4x - 3 = - 2x + 9 ( add 2x to both sides )
6x - 3 = 9 ( add 3 to both sides )
6x = 12 ( divide both sides by 6 )x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
y = 4(2) - 3 = 8 - 3 = 5
Then x = 2, y = 5

nick works at a job that pays $6.00 per hour. if he works h hours and makes 192.00 dollars this week, how many hours did nick work this week?
Answer:Ok so he makes about 6.00 bucks an hour so if he works 30 hours how much will he need to make 192.00 bucks.
Step-by-step explanation: Multiply 6.00 by 30 hours= 180 and u need 192$
so 192-180=12 so add 2 more hours to your 30 hours which makes it 32 hours.
If nick works 30 hours plus 2 more hours a week, he will make a total of $192.

Answer:
A = 74295.
Step-by-step explanation:
74*9*
- the last number must be a 0 or a 5.
So we try 74090/45 - not an integer
74095/45 = No
74190/45 No
74195/45 No
74295 / 45 = 1651 So that's it,

Damon buys lumber worth $562. He gets a 20% contractor's discount. The sales tax is 6%. His credit card gives him 2% off. How much does he pay?
Answer: $404.64 and 157.36 dollars to save
Step-by-step explanation:
Answer: $467.05
Step-by-step explanation:
The price is $562
20% off = 562 - 20% of 562 = 562 - 0.2(562) = $449.60
6% tax = 6% = 6/100 = 0.06
449.60 + 0.06*449.60 = $476.58
2% off from credit card = 476.58 - 0.02(476.58) = $467.05
$467.05 is the answer
