2(x/8 + 3) = 7 + 1/4x what is x

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:

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

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]

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

Answer:

-3/4

Step-by-step explanation:

to get the slope use u need two points and substitute them into

slope (m) = [tex]\frac{y2-y1}{x2-x1}[/tex]

the two clearest points here are the y-intercept:(0,6) and x-intercept:(8,0)

m= [tex]\frac{6-0}{0-8}[/tex] = -3/4

Cant realy give step by step- i just know

The solution 2x² - x - 1 is equivalent to expression y + yz.

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.

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

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.

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 <>
