The given expression is:
4 - 8 (3/4) + 1/4

To start, we will convert all the numbers to be having a denominator of 4 as follows:
4 is equivalent to 16/4
-8 (3/4) is equivalent to -24/4
1/4 already has 4 as a denominator

Now, the new expression became:
16/4 - 24/4 + 1/4

Since they all have a common denominator, the result can be computed by adding numerators as follows:
16/4 - 24/4 + 1/4
= (16-24+1) / 4
= -7/4

The correct choice is: 
A. -7/4

Marina CMI [18]

Answer:

Step-by-step explanation:

A = B+4

D = 2A

B = 2C

D-C =  38

2A - B/2 = 38

a slice of bread has 1.5 g of fat, 19 g carbohydrate and 4 g protein. how many kcal in the slice? please show all of you work in
dlinn [17]

Answer:

The answer is 105.5 kcal/slice of bread.

Step-by-step explanation:

The kcal per gram of:

  • protein = 4kcal/g.
  • carbohydrate = 4kcal/g.
  • fat = 9kcal/g.

Now, you have:

  • 1.5 g of fat + 19g of carbohydrate + 4g of protein = 1 slice of bread.

If we multiply the amount of components by his kcal:

  • 1.5g * 9kcal/g + 19g * 4kcal/g + 4g * 4kcal/g;

Now gram/gram = 1, and we can cancel the grams in the equation:

  • 1.5* 9kcal + 19 * 4kcal + 4 * 4kcal = 105.5kcal;

Finally, the result of the kcal of the slice bread is:

  • 105.5 kcal/slice of bread.

A cylinder with a 2 centimeter diameter is drilled through the triangular prism shown on the left find the volume of the prism
saw5 [17]

Answer:

The volume of a prism on its own = 248.5cm^3

The volume of a cylinder  = 87.92cm^3

Step-by-step explanation:

The volume does not change for the prism as the hole was drilled.

We can show the drilled space with v(l) and (p) for prism V

v(l) 248.5p - 87.92p + 87.92p

= 248.5p
