Answer:
Distribute
Step-by-step explanation:
4 x 5 = 20
4 x -a = -4a
-4a + 20 = 12
-20 From both sides
-4a = -8
Divide both sides by negative 4
a = 2
Answer:
Step-by-step explanation:
4(5-a)=12 divide each side by 4
5-a=3 subtract 5 from each side
-a=-2 divide each side by -1
a=2
or
4(5-a)=12 carry out multiplication indicated on left side
20-4a=12 subtract 20 from each side
-4a=-8 divide each side by -4
a=2

What is 25.48271 increased by 45 thousandths?
Answer: 25.52771
Step-by-step explanation:
i got this answer and it was right :D
The required answer would be 25.48271 if 25.48271 increased by 45 thousandths.
What are Arithmetic operations?Arithmetic operations can also be specified by subtracting, dividing, and multiplying built-in functions. The operator that performs the arithmetic operation is called the arithmetic operator.
+ Addition operation: Adds values on either side of the operator.
For example 12 + 2 = 14
- Subtraction operation: Subtracts the right-hand operand from the left-hand operand.
for example 12 -2 = 10
* Multiplication operation: Multiplies values on either side of the operator
For example 12*2 = 24
We have been given that 25.48271 increased by 45 thousandths.
Therefore, 25.48271 + 45/1000
⇒ 25.48271 + 0.045
⇒ 25.52771
Hence, the required answer would be 25.48271.

The distance between the points(-3, -5) and (2,7) on the coordinate plane is given as 5^2+ t^2. what us the value of t
Answer:
Step-by-step explanation:
so we can use [tex]t^{2}[/tex] + 25 as one expression and the find the distance between the points and set the expression equal to that number. That's our strategy.
dist = the square root of [tex]x^{2}[/tex] + [tex]y^{2}[/tex]
where x and y are the change in x2 to x1 and y2 to y1
P1 = ( -3, -5)
P2 = (2, 7 )
dist = square root of ( [2 -(-3) ]^2 + [7-(-5)]2)
dist = sq rt ( 5^2 + 12^2 )
dist = sq rt ( 25 + 144)
dist = sq rt (169)
dist = 13
now set our eq. equal to that number
[tex]t^{2}[/tex] + 25 = 13
[tex]t^{2}[/tex] = -12

y = 8x + 5, where x represents the number of hours. What
does the slope of the equation represent?
9514 1404 393
Answer:
dollars per hour
Step-by-step explanation:
If m is the slope, the units of m can be found by considering the units of x and y.
y is in dollars
x is in hours
Then from the point of view of units, we have ...
dollars = m × hours
m = dollars/hours
The slope in the equation is the rental charge in dollars per hour.

A movie theatre charges adults $10 to see a movie and charges children $6. If there wereq 120 people who saw a movue and the theatre collected $928, home many attendees were adults
Answer:
The number of adults tickets sold equals 52.
Step-by-step explanation:
First, we need to establish the system of equations:
x= number of adults tickets sold
y= number of kids tickets sold
10x + 6y= 928
x + y=120
Now, we isolate x in one equation and change it in the other to obtain its value:
x= 120 - y
10(120 - y) + 6y = 928
1,200 - 10y + 6y = 928
272 = 4y
68 = y
x= 120 - 68= 52
how many solutions does 9x-18=3(3x-6)have?
Answer:
0
Step-by-step explanation:
9x-18=3(3x-6)
3(3x-6)=9x-18
9x-18=9x-18
9x-9x=0
-18+18=0
Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
9x - 18 = 3 (3x - 6)
The equation 9x - 18 = 3 (3x - 6) has infinitely many solutions.
What is a solution?Solutions are the values of an equation where the values are substituted in the variables of the equation and make the equality in the equation true.
Example:
2x + 3 = 5
2 x 1 + 3 = 5
2 + 3 = 5
5 = 5
Where x = 1 is a solution.
We have,
9x - 18 = 3 (3x - 6)
9x - 18 = 9x - 18
Whatever value we put for x we will always get the same in both sides of the equation which means the equation is satisfied.
We see that the equation is equivalent.
This means the equation will have infinitely many solutions.
Thus,
The equation 9x - 18 = 3 (3x - 6) has infinitely many solutions.
