Answer:

Step-by-step explanation:

Question 1 is  2.

Question 2. 3 3/5 + 3 3/5 = 6 6/5 which equals 7 1/5 if you add another one.

so the answer for question 2 is " 1.521.

Answer:

x = 2, y = 5

Step-by-step explanation:

Given the 2 equations

y = - 2x + 9 → (1)

y = 4x - 3 → (2)

Substitute y = 4x - 3 into (1)

4x - 3 = - 2x + 9 ( add 2x to both sides )

6x - 3 = 9 ( add 3 to both sides )

6x = 12 ( divide both sides by 6 )x = 2

Substitute x = 2 into either of the 2 equations and evaluate for y

Substituting into (2)

y = 4(2) - 3 = 8 - 3 = 5

Then x = 2, y = 5

Answer:

Hello! Answer: 116.64

Step-by-step explanation:

What I did was multiplied 5.4 by 7.2 by 6 and we get a total of 233.28 then we just divide by 2 so...

233.28 ÷ 2 = 116.64 HOPE THAT HELPS!

Answer:

Step-by-step explanation:

To find the volume of a three dimensional shape, you can multiply all three dimensions(length, width, and height).

Volume = 5.4 * 7.2 * 6

Volume = 233.28

If you round to the nearest tenth place, your answer is 233.28 inches cubed . However, if you think about a triangle, the area is base times height divided by two. Similarly, you have to divide the volume by two to get your final answer. Thus, your final answer is (C) 116.64

Answer:

A: D

B: 20

Step-by-step explanation:

D is the correct answer because it can correctly determine what B will be.

We can calculate the problem and we get 20.

Answer:

0.4m = 8

20 minutes

Solve for m

Divide both sides by 0.4

m = 20 minutes

Answer:Ok so he makes about 6.00 bucks an hour so if he works 30 hours how much will he need to make 192.00 bucks.

Step-by-step explanation: Multiply 6.00 by 30 hours= 180 and u need 192$

so 192-180=12 so add 2 more hours to your 30 hours which makes it 32 hours.

If nick works 30 hours plus 2 more hours a week, he will make a total of $192.

Answer:

A) 9 cm

Step-by-step explanation:

By the Triangle Inequality, any two sides of a triangle must be greater than the remaining side.

In order to minimize the perimeter, we will assume that 4 cm is the longest side.

Thus, the two remaining sides must be greater than 4.

Since we are given that the sum of the two remaining sides is a whole number, the smallest whole number value greater than 4 is 5.

Hence, the smallest perimeter possible 9 cm.

Our answer is A.

Answer:

Hello! answer: 17

Step-by-step explanation:

Assuming this is the Pythagorean theorem our formula would be

a^2 + b^2 = c^2

meaning both of those sides multiplied by themselves added together will equal a number which is the result of c multiplied byitself sorry it sounds confused but...

15 × 15 = 225 8 × 8 = 64 225 + 64 = 289

the square root or the (number multiplied byitself that equals 289) is 17 because

17 × 17 = 289 so × = 17 I hope that helps!

Answer:

x = 17 cm

Step-by-step explanation:

Since it is a right triangle and you are trying to find x, you can use the pythagorean theorem.  (a² + b² = c²)

First, plug the values into the equation:  (a and b represent the legs and c represents the hypothenuse; otherwise known as the longest side.)  

8² + 15² = c²

Square 8 and 15( or multiply them by themselves):

64 + 225 = c²

Add:  

289 = c²

Take the square root of both sides:  

√289 = √c²

Simplify:

17 = c

Therefore, x = 17 cm.  

Hope this was helpful!  Have a nice day!  :)

Answer:

= 2.75823202 quarts

Step-by-step explanation:

1.40513707 imperial quart = 64 US ounces

1.66534763 imperial quart = 8 cups

0.83267382 imperial quart = 2 US pints

1.40513707+1.66534763+ 0.83267382 = 3.90315852

conversion to gallons = 1.171875

2 - 1.171875 =0.828125

0.828125 gallons conversion x 3.33  = 2.75823202 quarts

2.75823202/0.828125  shows s the conversion rate from gallons to quarts

= 3.33

The answer is = 2.75823202 quarts

Answer:

b  =  −1

b  =  −4

Step-by-step explanation:

Common Factor

Divide both sides of the equation by the same term

Use the quadratic formula

Answer:

-1 or -4

Step-by-step explanation:

first all you have to do is to multiply 12 by 3b² to give you 36b² and then find a number(x) multiplied by another number(y) to give you 36b² and those two numbers must sum up to give you 15b

doing this, we would have our two numbers to be

12b and 3b

replace these two numbers with 15b in the equation

3b² + 12b + 3b + 12=0

(3b²+12b) + (3b+12)=0

3b(b+4)+3(b+4)=0

note: the numbers in the brackets must be the same

(3b+3)(b+4)=0

therefore, 3b + 3= 0 or b + 4= 0

3b+3= 0

3b=-3

b=-3/3

b=-1

or

b+4=0

b=-4

Answer: X=8

Step-by-step explanation:

60                            96

5                                 x

5*96/60=8

Answer:

8

Step-by-step explanation:

Write a proportion :)

Choose 96 and x and 60 and 5, for example.

[tex]\frac{60}{5} = \frac{96}{x}[/tex]

your equation will be 60(x)=96x5

60x=480

divide and you get 8!
