Answer:

8

Step-by-step explanation:

[tex]-8n - 8 = -72\\-8n = -72 + 8\\-8n = -64\\n = 8[/tex]

Answer: 8

Step-by-step explanation:

Multiplying both sides by -1, we get:

8n + 8 = 72

8n = 72-8

8n = 64

n = 64/8 = 8.

Joshua deposited

(a). $12.85 in coins

(b). $77.14 in checks

The linear equation in one variable is an equation which is expressed in the form of ax + b = 0, where a and b are two integers, and x is a variable and has only one solution.

According to the given question

Joshua deposited checks worth six times the value of the coins he deposited.

Let Joshua deposit the value of coins be x. Then the value of x will be 6x

There is total deposit of $90.

⇒ x + 6x = 90

⇒ 7x = 90

⇒ [tex]x = \frac{90}{7}[/tex] =$12.85

Therefore,

[tex]6x = \frac{90(6)}{7} =\frac{540}{7}[/tex] = $77.14

Hence, he deposit total $12.85 in coins and $77.14 in checks.

The equation for the situation is [tex]5x+6(0.95)=11.95[/tex]

The solution to the equation is [tex]x=1.25[/tex]

First, you must set up the equation.

[tex]5x+6(0.95)=11.95[/tex]

Then, you must simplify the terms.

[tex]5x+5.7=11.95[/tex]

Next, subtract 5.7 on both sides.

[tex]5x=6.25[/tex]

Finally, divide 5 on both sides

[tex]x=1.25[/tex]

The cost of each doughnut is $1.2 and the equation is 5(0.95) + 6x = 11.95 if the total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.

It is defined as the relation between two variables, if we plot the graph of the linear equation we will get a straight line.

If in the linear equation, one variable is present, then the equation is known as the linear equation in one variable.

It is given that:

The total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.The cost of each cookie is $0.95.

The cost of 1 doughnut is x.

Total cost = $11.95

Total cost = 5(0.95) + 6x

11.95 = 5(0.95) + 6x

Or

5(0.95) + 6x = 11.95

After solving

x = $1.2

Thus, the cost of each doughnut is $1.2 and the equation is 5(0.95) + 6x = 11.95 if the total cost of 5 doughnuts and 6 cookies at a bakery is $11.95.

The options are:

6(0.95) + 5x = 11.95

5(0.95) - 6x = 11.95

5(0.95) + 6x = 11.95

5(0.95) + 6(11.95) = x

Step-by-step explanation:

The number of rate eaten by dog after 200 minutes: 2 pounds

A ratio is a divisional comparison of two quantities. It uses a fraction or quotient to represent the relationship between two numbers or quantities. For instance, we can describe the ratio 3:5 or the fraction 3/5 if we declare that there are 3 guys for every 5 ladies in a classroom.

Contrarily, the proportion equation declares that two ratios are equivalent. We can utilise proportion to solve problems with unknown amounts if we have two ratios that are equivalent.

We can use proportion to solve this problem:

If a dog eats 0.5 pound of food every 50 minutes, then in 1 minute, the dog will eat 0.5/50 = 0.01 pound of food.

Therefore, in 200 minutes, the dog will eat 0.01 x 200 = 2 pounds of food.

So the dog will have eaten 2 pounds of food after 200 minutes.

Answer:

Step-by-step explanation:

Since, ΔBCM ≅ ΔZYR,

∠B ≅ ∠Z

∠C ≅ ∠Y

∠M ≅ ∠R

And BC ≅ ZY

CM ≅ YR

BM ≅ ZR

a). CM = YR = 11 m

b). BM = RZ = 15 m

c). YZ = BC = 8 m

d). m∠B = m∠Z = 45°

e). m∠M = 180° - [m(∠B) + m(∠C)]

             = 180° - (45 + 103)°

             = 180° - 148°

             = 32°

f). m∠Y = m∠C = 103°

The side lengths are as follows: YZ is 8, BM is 15, and CM is 11. and angle B has a measure of 45 degrees. The angle C is 103 and the angle m is 32.

Congruent triangles are two triangles that are the same size and shape. They remain congruent if we flip, turn, or rotate one of two congruent triangles. If the sides of two triangles are the same, they must have the same angles and thus be congruent.

Congruent triangles have equal corresponding sides and angles

The measure of the side lengths are: YZ = 8,BM = 15 and CM = 11

The measure of the angles is angle B = 45. angle C = 103 and  angle m  =32

The given parameter is:

Tri angle BCM = Triangle ZYR

This means that triangles BCM and ZYR are congruent.

So, we have the following congruent sides

YZ = CB

BM = ZR

CM = YR

so, the measure of the side lengths are:

YZ = 8

BM = 15

CM = 11

Also, we have the following congruent angles

angle B = angle Z

angle C =  angle Y

angle M =  angle R

the measure of the angles are

angle B = 45

angle Y = 103

The measure of angle M is calculated using:

∠M + ∠C + ∠B = 180

∠M = 32

Therefore, The measure of the side lengths is: YZ is 8, BM is 15 and CM is 11. and The measure of the angles is angle B is 45. angle C is 103 and angle m  is 32.

Answer:

  5.5 hours

Step-by-step explanation:

The presumption in these cases is that the rate of doing work is proportional to the number of machines. So, 4 times as many machines can do the work 4 times as fast. That is, the same job can be completed in 1/4 the time:

  (22 h)(1/4) = 22/4 h = 5.5 h

It would take 5.5 hours to fill the order.

Answer:

5.5

Step-by-step explanation:

it is 5.5 because

22 divided by 4 is 5.5

0.75

Step-by-step explanation:

Constant of proportionality between p and n, is the ratio of both proportional quantities.

Thus, given the equation, [tex] p = 0.75n [/tex], of which Lopez uses, this equation represents the relation between both quantities.

The ratio of p and n = the constant of proportionality.

Thus:

[tex] p = 0.75n [/tex]

[tex] \frac{p}{n} = \frac{0.75n}{n} [/tex]

[tex] \frac{p}{n} = 0.75 [/tex]

Step-by-step explanation:

The degree of the polynomial is 7 as the highest power in its terms is 7.

So, the correct option is A.

The degree of a polynomial is the highest power that its terms pertain (for multi-variables, the power of term is the addition of the power of variables in that term).

Thus, in
