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

Answer:
Question 4: (C)
Question 5: (B)
Step-by-step explanation:
$1.50C + $4A= $5050
C + A = 2200
-4(C + A = 2200)
-4C - 4A = -8800
1.50C+4A = 5050
-----------------------
-2.5C =- 3750
-2.5C/-2.5 =- 3750/-2.5
C = 1500
C + A = 2200
1500 + A =2200
1500 - 1500 + A = 2200 - 1500
A = 700
CHECK
$1.50C + $4A= $5050
$1.50(1500) + $4(700)= $5050
$2250 +$2800 =$5050
$5050 = $5050
C + A = 2200
1500 + 700 =2200
2200 = 2200
Answer:
C. rectangle (not a square)
Step-by-step explanation:
So image that the wire just sliced that piece of the cube right off:
It would give you a triangular prism,
HOWEVER, this is asking for the cross section:
The part of this triangular prism that was actually connected to the cube
and in this case, it would show that the bottom of the cut off part is rectangle.
You can also think of this as: What shape would be left over on the cube?
Cutting this piece off would give you a shape left over that is a rectangle.
