Answer:

17x + 4

Step-by-step explanation:

The -(- would be turned into a positive due to the rule of two negatives makes a positive. You wouldn't add the 4 into either of the numbers with a variable, you would only add the 10x and 7x.

Answer:

3x+4

Step-by-step explanation:

Apply the distributive property to get 10x - -4-(7x). Now we can turn the two negatives into a positive to get 10x+4-7x. Now, subtract 7x from 10x to get 3x. This will leave you with 3x+4.

Answer:

The answer is Tim, because each point is fraction 3 over 8 unit away from 0.

Step-by-step explanation:

The absolute value is how far away a number is from 0 on a number line so since -3/8 is still 3/8 away from 0 the absolute value would be 3/8.

The graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

None of the given options is correct

The given equation is:

y  =  x  -  2

Find the x-intercept by making y = 0 and finding the corresponding x-value

y  =  x  -  2

0   =  x  -  2

x  =  2

The line y = x - 2 passes through the point (2, 0)

Also, find the y-intercept by making x = 0 and finding the corresponding y-value

y  =  x  -  2

y  =  0  -  2

y  =  -2

The line passes through the point (0, -2)

Therefore, the graph that represents y = x - 2 is a coordinate plane with a line passing through (0, -2) and (2, 0).

Answer:

59 hamburger patties

Step-by-step explanation:

14 3/4 divided by 1/4 is 59

Answer:

Option #1 (59 hamburger patties)

Step-by-step explanation:

First, add 6 1/4 and 8 1/2 to get the total amount of pounds you have.

You find a common denominator to add. In this case, the common denominator would be 4.

8 1/2 will become 8 2/4

6 1/4 + 8 2/4 = 14 3/4

Now we divide this number by 1/4

(14 3/4)/(1/4) =

59/4 * 4/1 =

236/4 = 59

Answer:

60896.7

Step-by-step explanation:

The volume of the hemisphere will be 60,865.86 cubic centimeters.

Volume is a proportion of consumed three-layered space. It is frequently evaluated mathematically utilizing SI inferred units or by different supreme or US standard units. Let r be the radius of the sphere.

Then the volume of the sphere will be

V = 4/3 πr³ cubic units

The diameter is 61.5 cm. Then the radius is calculated as,

r = d / 2

r = 61.5 / 2

r = 30.75 cm

The volume of the hemisphere is half of the volume of the sphere, then the volume is calculated as,

V = (1/2) x (4/3) x π r³

V = (1/2) x (4/3) x 3.14 x (30.75)³

V = 2.0933 x 29076.04688

V = 60,865.86

The volume of the hemisphere will be 60,865.86 cubic centimeters.
