Please answer ASAP!

Answer:

13

Step-by-step explanation:

what number is 26% of 50 is the question

you can set up a proportion:   is  =   percent

                                                  of           100

what number 'is' = you are looking for this, so assign a variable

'of = 50

26% =  26  

            100

n  = 26      You can cross-multiply to find 'n'

50     100

100n = 1300

n = 13

Answer:

The correct answer is x = -92/9 or x = -10.2

Step-by-step explanation:

(The error is that the student didn't multiply 8 inside the parenthesis )

Steps to show work:

3/4x + 8 = 1/3

9x + 96 = 4 ➙ 9x = 4 - 96

9x = -92

x = -10.2 or -92/9

Answer to 32:

You need to find a common denominator and then multiply both sides of the equation by that number. You can do practically anything you want one side of the equation, as long as you do it to the other side as well.

Answer:

c, d and e

Step-by-step explanation:

A linear expression is an expression in which sum of exponents of variables is at most 1 in each of its terms.

Option a: [tex]3x - 2[/tex]

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option b: [tex]-9y[/tex]

Here, the exponent of the variable is 1.

So, it is a linear expression.

Option c: [tex]-7x^2 + 4x[/tex]

Here, the highest exponent of the variable is 2.

So, it is NOT a linear expression.

Option d: [tex]-\frac{1}{2} x^2[/tex]

Here, the exponent of the variable is 2.

So, it is NOT a linear expression.

Option e: [tex]8xy[/tex]

Here, sum of exponents of variables is 2.

So, it is NOT a linear expression.

Hence, c, d and e are NOT algebraic expressions.

Answer:

Getting through ratio method

100-20=80 percent have to pay

18:80

x:100

cross multiply

80 x x=18 x 100

80x=1800

x=1800/80

x=22.5

So the original price was $22.50

9.60x15percent gives you $1.44- 9.60= 8.16

Answer:

1.82

Step-by-step explanation:

Add the prices to get the subtotal:

Sweet Tea:

2.49 * 2 = 4.98

4.98 + 15.99 + 4.99 = $25.96

The subtotal is $25.96

The sale's tax in Miami is 7% (the base 6% for FL, and the extra 1% for Miami).

$25.96 * 0.07 = 1.817 ≈ 1.82

The tax should be 1.82.

Hope this helps.

Step-by-step explanation:

First simplify it.  Combine like terms.

0.2 - 2m = 2.1m + 2.5 - 1.8m

0.2 - 2m = 0.3m + 2.5

Then isolate m.  Add 2m on both sides, then subtract 2.5 from both sides.

0.2 - 2m = 0.3m + 2.5

        0.2 = 2.3m + 2.5

       -2.3 = 2.3m

Now divide by 2.3 to find m.

       -2.3 = 2.3m

           -1 = m

And so m = -1.

Step-by-step explanation: use a calculator

The answer is A. Both equations add up to 88.

The question is incomplete. Here is the complete question.

A family needs to build a fence around their rectangular home and square pool, depicted below. A rectangle labeled home has its right side (2 + 5x) yards and its bottom side labeled (3 + 10x)yards. The square, labeled pool, is smaller than the rectangle. One of its side is labeled (2x)yards. The total amount of fencing they need can be written as x + 10. If x = 5:

The family needs _____ yards of fencing for their home.

The family needs _____ yards of fencing for their pool.

Answer: 160 yards

               40 yards

Step-by-step explanation: Perimeter is the sum of every side of a polygon.

Rectangle and Square are quadrilateral, i.e., have 4 sides each, but in a rectangle, the 2 parallel sides are equal, while in a square, 4 sides are equal.

To determine the amount of yards to fence a rectangle home:

P = 2l + 2w

where

l is length (in this case, bottom side)

w is width (right side)

P is perimeter

P = 2(2 + 5x) + 2(3 + 10x)

P = 4 + 10x + 6 + 20x

P = 10 + 30x

As x = 5:

P = 10 + 30(5)

P = 160

The family will need 160 yards of fencing for their home.

For the square pool:

P = 4s

with s representing a side of the square

P = 4(2x)

P = 8x

As x = 5:

P = 8(5)

P = 40

The family needs 40 yards of fencing for their pool.

Answer:

38, 160, 40

Step-by-step explanation:

Answer:

-80 ; 2 ; - 15 ; - 15

Step-by-step explanation:

Given that:

1.)

A withdrawal of $80, will cause reduction in the initial value, hence, negative

= - 80

2.)

A 2 - inch rise in water level, indicates increase from initial level, hence, positive

= + 2

3.)

A lose of 15 pounds indicates reduction in weight, hence, negative

= - 15

4.)

Draining 15 gallons of water from a fish tank indicates reduction Hence, negative

= - 15

Answer:

division property of equality

Step-by-step explanation:

Consider the equation and its solution.

In the first step, 8 is distributed inside the parenthesis. So distributive property is used.

In the second step, 16 is added on both sides. So addition property is used.

In the last step , 8 is divided on both sides. So, division property of equality is used.

Step-by-step explanation:

Answer:

division property of equality

Step-by-step explanation:

because you divide 8 and 80 to have the x alone leaving you with x=10

Answer:

25000

0.15

−1957.523

Step-by-step explanation:

Given the function :

Vn=250000.85n

Value of car due to Depreciation,

V(n) value of car after n years.

Initial value of car ; value of car at year 0

V(0) = Vn=25000(0.85)^(0)

V(0) = 25000(0.85)^0

V(0) = 25000(1)

V(0) = 25000

The Decay rate = annual Depreciation

According the exponential function.

mb^n

m = initial value

b = 1 - Decay rate

Relating to the equation given :

b = 0.85

0.85 = 1 - Decay rate

Decay rate = 1 - 0.85

Decay rate = 0.15

Value lost in fifth year : V(5) - V(4)

n = 5

V(5) = 25000(0.85)^5

V(5) = 25000 * 0.4437053125

V(5) = 11092.6328125

V(4) = 25000(0.85)^4 = 13050.15625

11092.6328125 - 13050.15625

= −1957.523

I believe it is y=7.45x

Step-by-step explanation:

Right so: each lunch box costs $7.45 as you bought 10 which costs $74.50

So if Y is the total cost and X is the number of boxes

it should be

y=7.45

as each box is $7.45 and you want how much all the boxes cost

Answer:

$4.20

Step-by-step explanation:

The Writing Emporium sells pencils and pens individually.

Step 1

We have to first find the price of a pencil and a pen

Let:

The price of a pencil = x

The price of a pen = y

Alana buys a pencil and two pens for $1.10.

x + 2y = 1.1 ......Equation 1

x = 1.1 - 2y

Jeffrey buys two pencils and a pen for $1.00.

2x + y = 1 ........ Equation 2

We substitute 1.1 - 2y for x in Equation 2

2(1.1 - 2y) + y = 1

2.2 - 4y + y = 1

-4y + y = 1 - 2.2

-3y = -1.2

y = -1.2/-3

y = $0.4

Solving for x

x = 1.1 - 2y

x = 1.1 - 2(0.4)

x = 1.1 - 0.8

x = $0.3

Hence:

The price of a pencil = x = $0.3

The price of a pen = y = $0.4

Step 2

How much does Edward spend to buy six pencils and six pens from the Writing Emporium?

6x + 6y

6($0.3) + 6($0.4)

$1.8 + $2.4

= $4.20

Therefore, Edward spent $4.20 to buy six pencils and six pens from the Writing Emporium.
