What does X equal?
2x + 2 = 4x + 4
Answer:
x = -1
Step-by-step explanation:
Given
2x + 2 = 4x + 4 ( subtract 4x from both sides )
- 2x + 2 = 4 ( subtract 2 from both sides )
- 2x = 2 ( divide both sides by - 2 )
x = - 1

Lin runs 12 laps around a track in 6 minutes. How many laps per minute is that? *
Step-by-step explanation:
6 min => Run 12 laps around the track
1 min => 12/6 = 2 laps around the track
Therefore Lin runs 2 laps per minute.
Answer:
2 laps per minute
Step-by-step explanation:
What we know:
Lin runs
12 laps
in 6 minutes
Laps per minute = [tex]\frac{Laps}{Minute} = \frac{12 laps}{6 minutes} = \frac{12}{6} = 2 \frac{laps}{minute}[/tex]

The ratio of money in Brian's wallet to Colin's wallet one day was 7:2.
Brian spent £39 that day.
Brian now had £4 less than Colin.
How much did they initially have altogether?
Answer:
£30
Step-by-step explanation:
Let Brian initially had money in his wallet = £x
and Colin had the money = £y
Since ratio of money in Brian's wallet to Colin's wallet was 5 : 1
Therefore,
⇒ x = 5y -------(1)
Brian spent £27 that day, so money left with him = £(x - 27)
After spending the money Brian had £3 less than Colin.
(x - 27) = (y - 3)
x = y + 27 - 3
x = y + 24 -------(2)
Now we equate the equations (1) and (2) for the value of x,
5y = y + 24
5y - y = 24
4y = 24
y = £6
From equation (2),
x = 6 + 24
x = £30
Therefore, Brian initially had £30.

Answer:
what the person above me said is correct :)
Step-by-step explanation:
Answer:
Both inequalities use the division property to isolate the variable, y. When you divide by a negative number, like –7, you must reverse the direction of the inequality sign. When you divide by a positive number, like 7, the inequality sign stays the same. The solution to the first inequality is y > -23, and the solution to the second inequality is y <>

adam can read 4 pages in 10 minutes. if adam reads at a constant rate, wich equation can be used to model the relationship between the number of pages he can read, p in t minutes?
Answer:
p=2.5t
Step-by-step explanation:
p stands for pages
2.5 is how long it takes him to read 1 page
t is the time
the reason why the t is next to 2.5 is so when you replace t with the actual time, you would multiply it by 2.5 to get how many pages he read in any amount of time

The solution 2x² - x - 1 is equivalent to expression y + yz.
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.
Operators which let do a basic mathematical calculation
+ 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
Given expression as :
⇒ y + yz
y = x + 1/2 and
z = 2x - 3
Substitute the values of y and z in the expression y + yz,
⇒ x + 1/2 + (x + 1/2)(2x - 3)
⇒ x + 1/2 + x(2x - 3) + 1/2(2x - 3)
⇒ x + 1/2 + 2x² - 3x + x - 3/2
Rearrange the like wise term and apply the arithmetic operations,
⇒ 2x² - 3x + x + x + 1/2 - 3/2
⇒ 2x² - x - 1
Hence, the solution 2x² - x - 1 is equivalent to expression y + yz.

1/5w+7=−2 what the number of W
Answer:
w = -45
Step-by-step explanation:
1/5w + 7 = -2
Subtract 7 from both sides.
1/5w = -9
Get w alone. To get w alone, divide 1/5 from both sides. You can also multiply 5 to both sides which is basically the same as dividing by 1/5.
w = -45

In 8 weeks, a hair salon gave 1,536 haircuts. The salon gave the same number of haircuts each week. How many haircuts did the hair salon give each week?
Answer:
192 haircuts
Step-by-step explanation:
Given that,
In 8 weeks, a hair salon gave 1,536 haircuts.
We need to find how many haircuts did the hair salon give each week.
8 weeks = 1,536 haircuts
1 week = (1,536 /8) haircuts
= 192 haircuts
Hence, the hair salon gives 192 haircuts each week.
