The product of negative 7 and a number squared is negative 28

Answer:

$655.61 is the new price. it was decreased in price by 65%

Step-by-step explanation:

A percentage is a number or ratio that can be expressed as a fraction of 100.

The percent discount on a damaged compact car is 35%.

A percentage is a number or ratio that can be expressed as a fraction of 100.

We have fractions for different percentages.

50% = 1/2

20% = 1/5

25% = 1/4

10% = 1/10

We have,

The selling price of the compact car = $27,500

The discounted price of the damaged compact car = $17,875

The discounted percentage of the car:

= (27,500 - 17,875) / 27,500 x 100

= 9625 / 27500 x 100

= 35%

Thus the percent discount on a damaged compact car is 35%.

Answer:

It is wrong because she should simplify both sides of the equation,distribute, combine like terms,subtract and divide to get the final answer.

4x−2(3x−4)+4=−x+3(x+1)+1

Step 1: Simplify both sides of the equation.

4x−2(3x−4)+4=−x+3(x+1)+1

4x+(−2)(3x)+(−2)(−4)+4=−x+(3)(x)+(3)(1)+1(Distribute)

4x+−6x+8+4=−x+3x+3+1

(4x+−6x)+(8+4)=(−x+3x)+(3+1)(Combine Like Terms)

−2x+12=2x+4

−2x+12=2x+4

Step 2: Subtract 2x from both sides.

−2x+12−2x=2x+4−2x

−4x+12=4

Step 3: Subtract 12 from both sides.

−4x+12−12=4−12

−4x=−8

Step 4: Divide both sides by -4.

−4x−4=−8−4

Given:

Total number of tickets = 80

Ratio of winning tickets to losing tickets is 2 : 8.

To find:

The number of tickets of each kind in the bag.

Solution:

Let the number of winning and losing tickets are 2x and 8x respectively.

Total number of tickets = 80

[tex]2x+8x=80[/tex]

[tex]10x=80[/tex]

Divide both sides by 10.

[tex]x=\dfrac{80}{10}[/tex]

[tex]x=8[/tex]

Now,

Winning tickets : [tex]2(8)=16[/tex]

Losing tickets : [tex]8(8)=64[/tex]

Therefore, the winning and losing tickets are 16 and 64 respectively.

Answer:

C. 2x-8

Step-by-step explanation:

You combine like terms so you will combine 3x and the -x which makes 2x. you then combine the +5 and the -13 which results in -8. The end result is 2x-8

Answer:

C. 2x - 8

Step-by-step explanation:

Step 1: Group like terms

5-8=2

3x - x =2x

Step 2: Add similar elements

2x+5-13

Step 3: Add/Stubtrct the numbers

5 - 13=-8

Answer: 2x-8

Answer:

see explanation

Step-by-step explanation:

The 2 angles are adjacent and supplementary, thus

2x + x + 84 = 180 , that is

3x + 84 = 180 ← required equation

Subtract 84 from both sides

3x = 96 ( divide both sides by 3 )

x = 32

Thus

∠ 1 = 2x = 2(32) = 64°

∠ 2 = x + 84 = 32 + 84 = 116°

Answer:

y = 2 - 2x

Step-by-step explanation:

Answer:

A. y = -2x + 2

Step-by-step explanation:

4x + 2y = 4

Move 4x to the other side of the equation.

2y = 4 - 4x

Divide the whole thing by 2 to get y by itself.

y = 2 - 2x

which can also be written as

y = -2x + 2

Answer:

The hiking club's member count increased by 48%.

Step-by-step explanation:

We are given two data values: 25 members and 37 members. We need to determine how many members the club gained first. We can set up an equation where we solve for an unknown, or x, in this case.

[tex]25 + x = 37\\\\x = 12[/tex]

The club increased by 12 members, so now we can divide this value by the initial amount of members and multiply the decimal we receive by 100 to express it in percentage form.

[tex]\frac{12}{25} =0.48\\\\0.48 \times 100 = 48\%[/tex]

Therefore, the club's member count increased by 48%.

Answer:

25+12=37

There would be 48%.

Answer:  Choice C.  [tex]x \ge -3[/tex]

============================================

Explanation:

The domain is the set of all allowed x inputs.

Here we see that x = -3 is the smallest x value possible as it is from the left-most point. The graph goes on forever to the right, so there is no largest x value. Effectively infinity is the largest x value even though infinity is not a number.

We can say the domain is [tex]-3 \le x < \infty[/tex] which can be simplified to [tex]-3 \le x[/tex] or [tex]x \ge -3[/tex]

In short: x can be -3 or larger.
