if y=3 then 14y equals
Answer:
42
Step-by-step explanation:
14(3)
Answer:
42
Step-by-step explanation:
first, substitute 3 for y in 14y. 14y means you are multiplying 14 and y, so when you plug in 3 for y, you're multiplying 14 and 3! :)
14y ⇒ 14(3)simplify by multiplying 14 · 3.
14(3) = 42so, when y = 3, 14y = 42.
you can check the answer by solving for y in 14y = 42.
divide both sides of the equation by 14.
14y/14 = 1y or y42/14 = 3after dividing, you're left with y = 3. that means 14y does indeed equal 42 when y = 3! :)

Use the Distributive Property to rewrite the expression without parentheses. -6 (4x + 3)
Answer:
−24x−18
Step-by-step explanation:
−6(4x+3)
=(−6)(4x+3)
=(−6)(4x)+(−6)(3)
=−24x−18
Answer:
-24x + -18
Step-by-step explanation:
-6 x 4 = -24
-6 x 3 = -18
making the expression -6(4x + 3) into

Find the value of y if the line through the points (-3, y) and (4, 6) has a slope of -2.
Answer:
-20
Step-by-step explanation:
(y - 6) / (-3-4) = -2
(y-6)/7=-2
y-6=-2*7
y=-14-6 =-20

A car wash detailed 273 cars in 7 hours. At what rate did the car wash detail cars in cars per hour?
Answer:
39 cars/hour
Step-by-step explanation:
We are trying to find the rate of cars/hour. So we need to divide the amount of cars by the amount of hours.
273/7 = 39
The wash detailed cars at a rate of 39 cars per hour.

Principal = $2,400
Rate = 4%
Time = 30 months
Answer:
$240
Step-by-step explanation:
I = prt
I = (2,400) (0.04) (2.5)
note: I changed 4% to a decimal and 30 months to 2.5 years
I = 96 (2.5)
I = 240 <-- The interest
------------------------------------------------------------------------------------------------------------
The simple interest accumulated on a principal of $ 2,400.00 at a rate of 4% per year for 2.5 years (30 months) is $240.00.

When building a house, the number of days required to build is inversely proportional to with the number of workers. One house was built in 147 days by 4 workers. How many days would it take to build a similar house with 42 workers?
Answer:
14
Step-by-step explanation:
[tex]147 \times 4 \div 42 = 14[/tex]
It would take 14 days to build a similar house with 42 workers
What is the fundamental principle of multiplication?Multiplication is the mathematical operation that is used to determine the product of two or more numbers. If an event can occur in m different ways and if following it, a second event can occur in n different ways, then the two events in succession can occur in m × n different ways.
We are given that the number of days required to build is inversely proportional to with the number of workers.
One house was built in 147 days by 4 workers.
So,
147 x 4 = 588
Now the days to build a similar house with 42 workers
588/ 42 = 14

Suppose both factors in a multiplication problem are multiples of 10. Why might the number of zeroes in the product be different than the total number of zeroes in the factors?
Answer:
Multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
Step-by-step explanation:
Let the first five multiples of ten be
10*1= 10
10*2= 20
10*3=30
10*4=40
10*5= 50
Suppose we chose 20 and 50.
Now multiplying 20 with 50 we get
20*50= 1000
IF we count the total number of zeros in the factors ( 20 and 50) they are 2.
But the number of zeros in the product (1000) are 3.
This is because when we multiply 2 with 5 we get 10 which adds to the existing number of zeros ( i.e 2) and we get a total of 3 zeros.
And multiplying 10 with 50 we get
10*50= 500
IF we count the total number of zeros in the factors ( 10 and 50) they are 2.
But the number of zeros in the product (500) are also 2.
This is because when we multiply 1 with 5 we get 5 which does not add to the existing number of zeros ( i.e 2) and the total number of zeros remain the same.
Similarly multiplying 20 with 30 we get
20*30= 600
IF we count the total number of zeros in the factors ( 20 and 30) they are 2.
But the number of zeros in the product (600) are also 2.
This is because when we multiply 2 with 3 we get 6 which does not have a zero and the total number of zeros remain the same as in the factors.
So we see that multiplying factors whose products are multiples of 10 add to the number of zeros when factors are multiplied as multiples of 10s.
The sum of three consecutive numbers is
42. Find the largest number in the set
Answer:
20
Step-by-step explanation:
Well consecutive numbers mean that the 3 numbers will follow each other in smallest to largest.
Example : 6, 7, 8 or 6,34,87
Non-Example : 7, 9, 6
As long as the number is greater than the one before it they are consecutive.
Following this rule I have come up with the numbers :
10, 12, 20
These three numbers are consecutive and equal to 42.
Now to find the largest number in this set just look at the greatest value which would be 20.
I don't have an entire explanation for this as I just did it in my head but I do hope it is correct.
I hope this helps! :)
