Answer:

x = 6, y =3

Step-by-step explanation:

4x-7y=3

x-7y=-15

Multiply the first equation by -1

-4x+7y=-3

Then add this to the second equation to eliminate y

-4x+7y=-3

x-7y=-15

------------------

-3x +0y = -18

-3x = -18

Divide by -3

-3x/-3 = -18/-3

x = 6

Now find y

x -7y = -15

6 -7y = -15

Subtract 6 from each side

6-7y-6 = -15-6

-7y = -21

Divide by -7

-7y/-7 = -21/-7

y =3

Answer:

Lola has $12

Step-by-step explanation:

To find how much money Lola has, we need to divide $28 by 2 1/3:

28 ÷ 2[tex]\frac{1}{3}[/tex] = [tex]\frac{28}{1}[/tex] × [tex]\frac{3}{7}[/tex] = [tex]\frac{12}{1}[/tex] = 12

Hope this helps! :)

Answer:

$12

Step-by-step explanation:

Lola has x.

Mary-Ann has 2 1/3 times what Lola has. Mary-Ann has $28

2 1/3 * x = 28

Change 2 1/3 into a fraction.

(7/3)x = 28

Multiply both sides by the reciprocal of 7/3 which is 3/7.

(3/7) * (7/3)x = (3/7) * 28

x = 12

Answer: Lola has $12.

Answer:

The answer is x = 25.

Answer:

Tiffany pays a total price of $9.81 for the basket of watermelons

Step-by-step explanation:

Percentages

To increase a certain amount by a given percentage, we can first calculate the increasing amount and then add it to the original amount.

If the price of the basket of watermelons was $9 before tax, and the sales tax is 9%, we first calculate the tax amount to pay:

$9 * 9 / 100 = $0.81

Now we add it to $9 to get the total price paid by Tiffany:

Total price = $9 + $0.81 = $9.81

Tiffany pays a total price of $9.81 for the basket of watermelons

Answer:

x = 100

Step-by-step explanation:

Original equation:

8x + 5x = 1300

Combine like factors

13x = 1300

Divide both sides by 13

x = 100

Hope this helps :)

Answer:

The correct option is;

Reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down

Step-by-step explanation:

The given function is f(x) = -0.1·cos(x) - 4

The parent cosine function is cos(x)

Therefore, f(x) = -0.1·cos(x) - 4 can be obtained from the parent cosine function as follows;

The negative sign in the function gives a reflection across the x-axis

The 0.1 factor of the cosine function gives a compression of 0.1

The constant -4, gives a vertical translation 4 units down

Therefore, the correct option is a reflection across the x-axis, vertical compression by a factor of 0.1, vertical translation 4 units down.

Answer:

✔ vertical compression by a factor of 0.5

reflection across the y-axis

✔ vertical translation 3 units down

vertical stretch by a factor of 0.5

✔ reflection across the x-axis

vertical translation 3 units up

vertical translation 0.5 units down

Answer:

572.88

Step-by-step explanation:

Use a calculator it makes it easier  

The solution of expression 68.2 × 8.4 after multiplying is,

⇒ 572.88

Given that,

A mathmatical expression to solve,

⇒ 68.2 × 8.4

Now, simplify the number and then multiply as,

⇒ [tex]68.2 \times 8.4[/tex]

⇒ [tex](68.2 \times \dfrac{10}{10} )\times ( 8.4 \times \dfrac{10}{10} )[/tex]

After multiplication the numbers we get;

⇒ [tex]\dfrac{682}{10} \times \dfrac{84}{10}[/tex]

⇒ [tex]\dfrac{57,288}{100}[/tex]

⇒ [tex]572.88[/tex]

Therefore, the solution of expression 68.2 × 8.4 is,

⇒ 572.88

Answer:

He spent 52.5 minutes reading.

Step-by-step explanation:

The equation from the word problem is 2(x+5)+25=140. Distribute 2 to the parentheses and get 2x+10+25=140. Combine like terms to get 2x+35=140. Subtract 35 from both sides and get 2x=105. Divide both sides by 2 and your final answer is x=52.5

Answer:

The difference between the high and low temperatures is 29°F

Step-by-step explanation:

Subtraction

The high temperature in Denver, Colorado was 25°F on Monday.

The low temperature was -4°F in the same place.

We are required to find the difference between the high and low temperatures.

We need to subtract 25 and -4:

Difference = 25°F - (-4°F)

Note we change the sign of the subtraction multiplying (-1) by (-1);

Difference = 25°F + 4°F

Difference = 29°F

The difference between the high and low temperatures is 29°F

150 to 170 successful free throws

Step-by-step explanation:

Total % of free throws made = 80%±5%

If attempted number of free throws = 200

Range of successful free throws to expect :

(80% - 5%) of 200 TO (80% + 5%) of 200

75% of 200 TO 85% of 200

(0.75 * 200) TO (0.85 * 200)

150 TO 170

150 - 170 successful free throws

Answer:

$2368.75

Step-by-step explanation:

Kedar earns a monthly salary of $2200 and a commission of 3.75%

He sold $4500 this month

The first step is to calculate his commission for this month

His commission can be calculated as follows

= 4500 × 3.75/100

= 4500 × 0.0375

= 168.75

Therefore yr amount earned this month can be calculated as follows

= 2200 + 168.75

= $2368.75

Answer:

Step-by-step explanation:

what is average speed:

"The average speed of an object is defined as the distance traveled divided by the time elapsed. Velocity is a vector quantity, and average velocity can be defined as the displacement divided by the time."

step one:

given data

Distances   Time

4km             32min

2km              22min

 1km              16min

the total distance covered is

4+2+1= 7km

the total time taken = 32+22+16=70min

the average speed= distance/time

average speed= 7/70= 0.1km per min

Answer:

No

Step-by-step explanation:

Lisa: 5 red beads to 3 yellow beads

Tim: 9 red beads to 6 yellow beads

5/3 & 9/6

5/3(2/2) = 10/6

10/6 & 9/6

10/6 > 9/6

10/6 is in fact greater than 9/6. So the answer is no.
