Solve 6 + 1/4a = 3 for a.

Answer:

Answer is A.44

Step-by-step explanation:

So we multiplying 18*2 to find a measure 18*2=36

so we know that 18*2 is equal to 36 but we now that we have 13 so. we take 36+12=44

Answer:

5 weeks

Step-by-step explanation:

Let's find how much money she saves a week by multiplying the decimal form of 60% and $70.

To get the decimal form of a percent you have to move the decimal to the left twice, like this: 60 ---> .60

Now that we have the decimal form of the percent we can multiply it by the 70 to find how much she saves a week:

(70)(.6) = 42

Therefore, Kendra saves $42 each week.

To find how many weeks it will take Kendra to buy the game system you divide $210 by the $42. Like this:

(210)/(42) = 5

All in all, it will take Kendra 5 weeks to save enough money to buy a game system that costs $210.

I hope this helps!!

Answer:

20

Step-by-step explanation:

Let :

Length of Anne's stride = x

Length of Phillips stride = x + 4

Number of steps taken to walk same distance :

Anne = 6 steps ; Philips = 5 steps

Distance moved = Length of stride * number of strides

Hence,

For same distance :

Anne's distance = Phillip's distance

x * 6 = (x + 4) * 5

6x = 5x + 20

6x - 5x = 20

x = 20

Length of Anne's stride = 20

  pieces of candy = 16 × boxes of candy

Step-by-step explanation:

Each "pieces" number is 16 times the corresponding "boxes" number, so we can write ...

  pieces of candy = 16 × boxes of candy

__

If you like, you can assign variables. Let x = boxes of candy, and y = pieces of candy. Then you have ...

  y = 16x

Answer: 4.5 hours

Step-by-step explanation:

First you put 60000 and change 2.5 hours into minutes then divide by that, inwhich you get 400. After getting 400 divide 108000 by 400 which equals 270, divide by 60 for hours.

It would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.

In mathematics, an expression is a combination of numbers, variables, and mathematical operations such as addition, subtraction, multiplication, and division. An expression can also include mathematical functions, parentheses, and other symbols.

Let x be the amount of time (in hours) it takes the pump to empty a tank containing 108,000 gallons of water.

Using the direct variation formula, we can write:

time = k x capacity

Where k is the constant of variation.

We can use the given information to find k:

2.5 = k x 60000

k = 2.5 / 60000

k = 0.00004167

Now we can use this value of k to find x:

x = k x 108000

x = 4.5

Therefore, it would take the same pump 4.5 hours to empty a tank containing 108,000 gallons of water.

Answer: A

Step-by-step explanation:

The values that satisfy the inequality are -45 , -50 , -56.23 etc..

Algebraic expressions are contrasted in a mathematical statement known as an inequality using the greater-than (>), less-than (<), and other inequality symbols. A pair of inequalities connected by and or or form a compound inequality. In this lesson, linear and compound inequalities in one variable will be resolved using the properties of inequalities. The study of absolute-value equations and inequalities continues.

Solving inequalities is very like solving equations, we do most of the same things , but we must also pay attention to the direction of the inequality.

The given inequality is of the form n < -15 . Since no other information is given about n we will consider n to be a Real number.

Hence any real number that is less that -15 will satisfy the inequality.

Therefore the values that satisfy the inequality are -45 , -50 , -56.23 etc..

Answer:

[tex]7.25*10^{9}[/tex]

Step-by-step explanation:

To write a number in scientific notation, you need to reduce the number to one which is between 0 and 10.

In this case, 725 and 72.5 aren't possible as they are more than 10.

7.25 is the number we want. So simply count the number of decimal places you need to move in order to turn 7,250,000,000 into 7.25.

7,250,000,000.0

725000000.00

7250000.000

725000.0000

72500.00000

7250.000000

725.0000000

72.50000000

7.250000000

In this case, it is 9.

Answer:

Angles measuring 90°, 45°, and 45°: Can make triangle

Angles measuring 27°, 35°, and 108°: Can not make triangle

Angles measuring 82°, 41°, and 57°: Can make triangle

Sides measuring 8 cm, 12 cm, and 5 cm: Can make triangle

Sides measuring 7 in., 4 in., and 13 in: Can not make triangle

Sides measuring 43 cm, 41 cm, and 58 cm: Can make triangle

Step-by-step explanation:

For the angles to form a triangle, there sum must be equal to 180°

Angles measuring 90°, 45°, and 45°

Sum of Angles = 90° + 45° +45° = 180°

Hence, this combination can make triangle.

Angles measuring 27°, 35°, and 108°

Sum of Angles = 27° + 35° + 108° = 170° ≠ 180°

Hence, this combination can not make triangle.

Angles measuring 82°, 41°, and 57°

Sum of Angles = 82° + 41° +57° = 180°

Hence, this combination can make triangle.

For three sides to form a triangle the sum of the two sides must be greater than the length of third side.

Sides measuring 8 cm, 12 cm, and 5 cm

(8 cm + 12 cm) > 5 cm (True)

(8 cm + 5 cm) > 12 cm (True)

(12 cm + 5 cm) > 8 cm (True)

Hence, this combination can make triangle.

Sides measuring 7 in., 4 in., and 13 in

(7 in + 4 in) > 13 in (False)

Hence, this combination can not make triangle.

Sides measuring 43 cm, 41 cm, and 58 cm

(43 cm + 41 cm) > 58 cm (True)

(43 cm + 58 cm) > 41 cm (True)

(41 cm + 58 cm) > 43 cm (True)

Hence, this combination can make triangle.

Answer:

A- Angles measuring 90°, 45°, and 45°.

C- Angles measuring 82°, 41°, and 57°.

D- Sides measuring 8 cm, 12 cm, and 5 cm

F- Sides measuring 43 cm, 41 cm, and 58 cm.
