Mai says that the equation 2x+2=x+1 has no solutions because the left side is double the right side. Do you agree with mai provide evidence for your reasoning.​

Answer: Option A.

Step-by-step explanation:

Simplifying

xy + -9z = 4

Solving

xy + -9z = 4

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '9z' to each side of the equation.

xy + -9z + 9z = 4 + 9z

Combine like terms: -9z + 9z = 0

xy + 0 = 4 + 9z

xy = 4 + 9z

Divide each side by 'y'.

x = 4y-1 + 9y-1z

Simplifying

x = 4y-1 + 9y-1z

Answer:

A) 60

B) 72/300

C) 150

Step-by-step explanation:

A) P(green) = ⅕

⅕ × 300 = 60

B) purple: 72

45+37+52+94+72 = 300

Therefore, 72/300

C) 1000 × (45/300)

150

a, The number of times is 60.

b. The probability for landing should be [tex]72/300[/tex]

c. The number of times is 150.

Since

a. The spinner shown is spun 300 times

and, the probability of green should be like [tex]1/5[/tex]

So here one-fifth of 300 should be 60.

b. The probability is

First the total be like

= 45+37+52+94+72

= 300

Now the probability is

=  [tex]72/300[/tex]

C) The number of times should be

[tex]= 1000 * (45/300)[/tex]

= 150

Answer:

129.4

Step-by-step explanation:

Calculation for what's the total length from the front of the first bus to the end of the last

First step is to multiply the given number of buses by the length of each one

Hence,

12.6 meters x 9 = 113.4 meters

Second step

Since there are 8 spaces in between we would multiply the 8 spaces by 2 meters

8 x 2 meters = 16

Now let calculate total length from the front of the first bus to the end of the last

16 + 113.4 meters =129.4

Therefore total length from the front of the first bus to the end of the last will be 129.4

Answer:

x = -20

Step-by-step explanation:

3/4x - 4 = -19

multiply by 4 to eliminate denominator

3x - 16 = -76

3x = -60

x = -20

Answer:

5 ± 2i√5

from the quadratic equation

Answer:

a=5b-3a-4b

Step-by-step explanation:

We first need to move all terms that do not contain a to the right side of the equation. We cancel terms on the left side by adding -4b to both sides of the equation. a+4b-4b=5b-3a-4b

Answer:

3600 tickets were sold for the musical performance.

Step-by-step explanation:

Given that:

Number of people seated for musical performance = 108

Percent to people to arrive yet = 97%

It means that the people who have already come are 3%.

Let,

x be the number of tickets sold.

3% of x = 108

[tex]\frac{3}{100}x=108\\[/tex]

0.03x = 108

Dividing both sides by 0.03

[tex]\frac{0.03x}{0.03}=\frac{108}{0.03}\\x=3600[/tex]

Hence,

3600 tickets were sold for the musical performance.

Answer:

Value after:

7 years = $9971.42

8 years = $8176.56

9 years = $6704.78

Rate of decay = 18%

Step-by-step explanation:

A $40,000 car depreciates in value about 18% per year for the life of the car.

Determine the value of the car after 7,8, and 9 years. What is the rate of decay?

The formula for Depreciation is

FV = PV( 1 - r)^t

Where

FV = Future value

PV = Present value = $40,000

r = Depreciation rate = 18% = 0.18

t = time in years

a) After 7 years

$40,000 (1 - 0.18)⁷

= $9971.4188227

= $9971.42

b) After 8 years

$40,000 (1 - 0.18)⁸

= $8176.5634346

= $8176.56

c) After 9 years

$40,000 (1 - 0.18)⁹

= $6704.7820164

≈ $6704.78

= $9971.42

The Rate of decay = 18%

Answer:

7/8 of ingredients

Step-by-step explanation:

To calculate the amount of ingredients in Maya's trail mix, we should first come up with a common denominator to convert all the fractions to.

Our LCD here could be 8, because 8 is divisible by 2 and 4, our other denominators.

1/8 stays as 1/8.

1/2 = 4/8

since 1 x 4 = 4 and 2 x 4 = 8

1/4 = 2/8

since 1 x 2 = 2 and 4 x 2 = 8

1/8 + 4/8 + 2/8 gets us 7/8.

(( I assume you are looking for the total amount in fraction form ))

Answer:

298

Step-by-step explanation:

5 equal groups of 745 would have 149 blueberries. You want to find how much is in 2 groups so you add 2 groups together, which is 149 + 149. That equals 298.

Answer:A

Step-by-step explanation:

Answer:

3. (-1 , 3) , 4

4. (0 , -7), 8

Step-by-step explanation:

circle: (x-h)² + (y-k)² = r²

3. x²+2x+y²-6y-6 =0

  (x²+2x+1) + (y²-6y+9) -16 =0

  (x+1)² + (y-3)² = 4²

center(-1 , 3)      radius: 4

4. x²+y²+14y-15=0

   (x+0)² + (y²+14y+7²) - 64 = 0

   (x+0)² + (y+7)² = 8²

center: (0 , -7)     radius: 8

Answer:

3. Center = (-1,3)   Radius = 4

4. Center = (0,-7)   Radius = 8

use completion of squares to find the solution, if you do not understand what this means, there is a great video on utube by the channel Prep Expert that explains finding the center of a circle based on an equation.

Answer:

One way to find the least common multiple of two numbers is to first list the prime factors of each number. Then multiply each factor the greatest number of times it occurs in either number. If the same factor occurs more than once in both numbers, you multiply the factor the greatest number of times it occurs.
