3y - 27 = 5y + 9 - y

3y - 5y + y = 27 + 9

-y = 36

y = -36

Answer:

Step-by-step explanation:

Evaluate x3−y2 if x=2 and y=34

substitute x=2 and y=32 into the expression:

= x3 - y2

= (2)3 - (34)2

= 6 - 68

= -62

An expression is defined as a set of numbers, variables, and mathematical operations. The value of the expression x³−y², when x=2, y=34 is −1,148.

In mathematics, an expression is defined as a set of numbers, variables, and mathematical operations formed according to rules dependent on the context.

Given the expression x³−y² and the value of the expression when x=2 and y=34 can be calculated by substituting the values in the expression. Therefore, the expression can be written as,

x³ − y²

Substitute the value of x and y in the expression,

= (2)³ − (34)²

Opening the bracket,

= 8 − 1,156

= −1,148

Hence, the value of the expression x³−y², when x=2, y=34 is −1,148.

Step-by-step explanation:

-2-(-4)-2

We can break down the problem first. The beginning of the problem is...

-2-(-4)

Two negatives make a positive. An equivalent way to say this is

-2+4

-2+4=2

Next, we can solve for the last part. At the end of the equation, you have to subtract 2, so that's what we'll do!

2-2=0

The answer to this is 0!

Answer:

8.5

Step-by-step explanation:

w is 8.5

Answer:

8.5

Step-by-step explanation:

-w=1.5-10                                           the opposite of 10 is negative 10

-w=-8.5                                            

w=8.5                                               you are trying to get just w not negative w              

                                                         so two negatives equal a positive or -1          

                                                         times -8.5 is a positive 8.5

Answer:

y=10x+28

Step-by-step explanation:

y=10x+28

y=(10*-2)+28

y=-20+28

y=8

The linear equation of the line is y + 2 = 10(x - 8)

The slope is given as:

m = 10

The point is given as:

(x1, y1) = (8, -2)

The equation in point slope form is calculated as;

y -  y1 = m(x - x1)

So, we have:

y + 2 = 10(x - 8)

Hence, the linear equation of the line is y + 2 = 10(x - 8)

Answer:

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Step-by-step explanation:

The equation that gives the total amount t in her account is t=120+20w, where w is the number of weeks since she opened the account.

To calculate the amount of money Alexis will have in her savings account after 5 weeks, you replace the number of weeks w since she opened the account by 5:

t=120+20*5

Solving, you get:

t=120+100

t=220

The amount of money Alexis will have in her savings account after 5 weeks is $ 220.

Answer:

3/4 quarts of yellow paint is needed

Step-by-step explanation:

From the question, we are told that:

In order to make purple he must mix red and blue paint together at a ratio of 2 quarts red to 1 quart of blue.

3 quart of Purple paint mix requires 2quarts of red paint and 1 quart of blue paint.

We are also told that:

When George wants to make brown paint he must mix purple and yellow paint together in a 1:1 ratio.

This means 1 Purple paint to 1 Yellow paint

4/4 quarts of Yellow paint = 1 yellow paint

3/4 quarts of Yellow paint = 3/4 quarts of purple paint

Answer:

11 1/5 feet!

Step-by-step explanation:

He needs a total of 27 9/10 feet! 11 1/2 + 5 1/5 is 16 7/10 feet! If we need 27 9/10 feet, we subtract 16 7/10 ft from 27 9/10 ft to get 11 2/10, which we can reduce 2/10 to be 1/5.

So, he needs 11 1/5 feet of wood more to build the doghouse for his new puppy!

The division rest of 74 by 7 equals 4, and the value of the quotient is 10. Proof: 74 = (7×10) + 4.

Step-by-step explanation:

hope this helped and is that iready??

The remainder of 74 divided by 7 is 4.

Division is one of the operation in mathematics where number is divided  into equal parts as that of a definite number.

When a number is divided by another number, the number which is being divided is the dividend. Divisor is the number which divides the dividend.

Quotient is the value after the division process.

Remainder is the remaining value after the division.

If the dividend is completely a factor of divisor, remainder will be zero.

Otherwise there will be a non zero number as the remainder.

74 is not a multiple of 7.

70 is the multiple of 7 which is closest to 74.

Remainder = 74 - 70 = 4

Hence the remainder is 4.

Length of the rectangle = 8cm

Width = 5cm

Note that when the scale was 1:7, syla multiplied the width by a factor of 7 i.e 5*7 = 35m

If syla changes the the scale to 1 cm : 10 m for the rectangle, then the width of the shorter side will be multiplied by a factor of 10 due to the change in scale i.e;

5 * 10 = 50m

Hence the width of the new stage will be 50 m

Step-by-step explanation:

The circumference (C) of a circle is calculated as

C = πd ( d is the diameter )

(4)

Here d = 18, thus

C = 18π in

(5)

Here C = 50π, thus

πd = 50π ( divide both sides by π )

d = 50 in

The radius r is one half of the diameter , thus

r = 50 ÷ 2 = 25 in

Answer:

$109.45

Step-by-step explanation:

On Monday in the morning you worked 4 hours, so plug in the equation.

12.50(4)= $50

On Monday in the afternoon you worked 4 hours and 45 min

12.50(4) = $50

Then do 12.50/60 to get .208 ≈ .21

So 45(.21) = $9.45

50 +50 + 9.45= 109.45

Answer: the perimeter of the square is 44

Answer:

44 ft

Step-by-step explanation:

The area (A) of a square is calculated as

A = s² ( s is the side length )

Here A = 121, thus

s² = 121 ( take the square root of both sides )

s = [tex]\sqrt{121}[/tex] = 11

Perimeter = 4 × 11 = 44 ft
