Use x for your variable. Do not simplify

Step-by-step explanation:

Answer: Soooo-----    x+(3x-13)

Step-by-step explanation:

So in this case i used x as number. Since we're not solving for anything this is just an expression. so the difference between triple the number so 3x and thirteen so (3x-13) and (a number) added so x+(3x-13) or number added to the difference between triple the number and thirteen

Answer:

The girl had 24 candies in her bag.

Step-by-step explanation:

Since, regarding the girl's candies, 4 of them were blue, 1/6 of them were grape, 1/4 of them were watermelon, 1/3 of them were cherry and 1/12 of them were sour apple, to determine how many candies were in her bag, the following mathematical calculation should be performed:

1/6 + 1/4 + 1/3 + 1/12 = X

2/12 + 3/12 + 4/12 + 1/12 = X

10/12 = X

12/12 - 10/12 = 2/12

2/12 = 4

1/12 = 2

2 x 12 = 24

Thus, the girl had 24 candies in her bag.

Answer:

Step-by-step explanation:

b and s are the pounds of blueberries and strawberries, respectively.

b+s ≥ 3

4b + 3s ≤ 21

The system of inequalities can be represented as x+y≥3 and 3x+4y≤21.

Inequality shows relation between two expression which are not equal to each others.

Given that,

Cost of blueberries = $4 per pound

and cost of strawberries = $3 per pound

Let strawberries are x pound and blueberries are y pound, according to condition there should at least 3 pounds of muffins,

Therefore, x+y≥3

And maximum amount is $21

Therefore, 3x+4y≤21

The inequalities are x+y≥3 and 3x+4y≤21.

Answer: Monitor C is the different one.

Step-by-step explanation:

The aspect ratio is the relationship between width and height.

So we only need to see the quotients between width and height for each monitor and see which quotient is different.

Monitor A:  

Quotient = 1152/864 = 1.333....

Monitor B:

Quotient = 800/600 = 1.333...

Monitor C:

Quotient = 1920/1080 = 1.777...

Monitor D:

Quotient = 1600/1200 = 1.333...

We can see that the one with a different aspect ratio is monitor C.

Answer:

The diameter is 30 inches.

Answer:

Please check the explanation.

Step-by-step explanation:

Part a)

Given that the two parallel lines are crossed by a transversal line.

Given that

m∠2 = 2x + 54 and m∠6 = 6x - 11

Angle ∠2 and ∠6 are corresponding angles.

Corresponding angles are congruent.

Thus,

m∠2 = m∠6

2x + 54 = 6x - 11

flipe the equation

6x - 11 = 2x + 54

subtract 2x from both sides

6x - 2x - 11 = 2x - 2x + 54

4x - 11 = 54

adding 11 to both sides

4x - 11 + 11 = 54 + 11

4x = 65

dvide both sides by 4

4x/4 = 65/4

x = 16.2500    (round to 4 decimal places)

Part b)

We have already determined

x = 16.2500

Given

m∠2 = 2x + 54

substitute x = 16.2500 in the euation

        = 2(16.2500) + 54

        = 86.5°

As angle ∠2 and angle ∠1 lie on a straight line. Hence, the sum of their angles must be 180°.

i.e.

m∠1 + m∠2 = 180°

substituting m∠2 =  86.5° in the equation

m∠1 + 86.5°  = 180°

subtracting 86.5° from both sides

m∠1 + 86.5° - 86.5° = 180° - 86.5°

m∠1 = 93.5°

Therefore, the measure of angle m∠1 is:

Answer:

x = 55

Step-by-step explanation:

Since 2 sides of the triangle are congruent, both 5, then the triangle is isosceles and the 2 base angles are congruent, both x , then

x + x + 70 = 180 ← sum of 3 angles = 180°

2x + 70 = 180 ( subtract 70 from both sides )

2x = 110 ( divide both sides by 2 )

x = 55

Answer:

55.52

Step-by-step explanation:

By sine rule:

[tex] \frac{ \sin x \degree}{5} = \frac{ \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ \sin x \degree = \frac{ 5 \: \sin 70 \degree}{5.7} \\ \\ x \degree = {sin}^{ - 1} ( \frac{ 5 \: \sin 70 \degree}{5.7}) \\ \\ x \degree = 55.516753493 \degree\\ \\ x = 55.52[/tex]

Answer:

x = 20

Step-by-step explanation:

Using Pythagoras' identity in the right triangle.

The square on the hypotenuse is equal to the sum of the squares on the other 2 sides, that is

x² = 12² + 16² = 144 + 256 = 400 ( take the square root of both sides )

x = [tex]\sqrt{400}[/tex] = 20

Total amount of water before it was drained will be 510 gallons.

"It is a ratio in which the two terms being compared have different units."

For given question,

We have been given  a table for  the number of gallons of water left in the tank after being drained for two amounts of time.

First we find the rate at which the water was drained from the tank.

[tex]r=\frac{450-330}{30-10}\\\\ r=\frac{120}{20}\\\\ r=6~gallons~per~minutes[/tex]

Let the amount of water in the tank before it was drained = 'x' gallons

And the initial time = 0

Using the rate formula,

[tex]r=\frac{x-450}{10-0}\\\\ 6=\frac{x-450}{10}\\\\ 60=x-450\\\\x=450+60\\\\x=510~gallons[/tex]

Therefore, total amount of water before it was drained will be 510 gallons.
