What is the missing side, x?

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:

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

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:

9.81 it was confirmed :)

Answer:

2.a. The price of 2.75 kg of pears is $4.62

2.b. The price of 0.19 kg of Pears is $ 0.3192

Step-by-step explanation:

The given parameters are;

The price of each kilogram of Pears = $1.68

Therefore, we have;

The price of a given mass of Pears = The mass in Kg of the Pears × The price per kg of Pears

2.a. The price of 2.75 kg of pears = The mass × The price per Kg = $1.68/kg × 2.75 kg = $4.62

The price of 2.75 kg of pears = $4.62

2.b. The price of 0.19 kg of Pears = The mass × The price per Kg = $1.68/kg × 0.19 kg = $ 0.3192

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:

x = 100

Step-by-step explanation:

Original equation:

8x + 5x = 1300

Combine like factors

13x = 1300

Divide both sides by 13

x = 100

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:

The answer is x = 25.

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

(4p-m)/4

m=-4 and p=2

Since you know what m and p represent, it shouldn't be hard to solve.

(4 [2] - [-4] )/4   The 4 would be positive since there are two negatives.

(8 + 4)/4 Do the work inside the parenthesis first...

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.

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:

Ren was 27.5 meters away from her family.

Step-by-step explanation:

Ren Qian was at a height of 10 meters to the ground. Let the distance from her vertical point on the ground to her family (i.e the ground distance) be represented by x.

But the angle of depression is measured with respect to the horizontal plane, so;

the vertical angle = [tex]90^{o}[/tex] - 20°

                             = [tex]70^{o}[/tex]

Applying the appropriate trigonometric function, we have;

Tan θ = [tex]\frac{opposite}{adjacent}[/tex]

Tan [tex]70^{o}[/tex] = [tex]\frac{x}{10}[/tex]

⇒ x = 10 x Tan [tex]70^{o}[/tex]

      = 10 x 2.7475

      = 27.475

x = 27.5 meters

Ren was 27.5 meters away from her family.

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
