Answer:
28.75 or 28 3/4
Step-by-step explanation:
This equation is made for Long Division:
115/4
4 cannot go into 1 evenly.
4 can go into 11, 2 times.
4x2=8
11-8=3
4 can go into 35, 8 times.
35-32=3
Add a zero at the end, then divide 4 into 30.
4 goes into 30, 7 times.
30-28=2
Add another zero, then divide again.
4 goes into 20, 5 times.
20-20=0
So, after you hit an even number you can stop dividing and put in your answer.
28.75
Solution:
Given, x=-3, y=6, and z=4
Putting these values in the given equation:
-15+(-x)+y
= -15+(-(-3)+6
= -15+3+6
= -15+9
= -6
Answer:
64 in³
Step-by-step explanation:
The volume (V) of a cube is calculated as
V = s³ ( where s is the length of the side )
Given
area = 16, then
s² = 16 ( take the square root of both sides )
s = 
= 4 , thus
V = 4³ = 4 × 4 × 4 = 16 × 4 = 64 in³
Answer:
The bag costs 1500, while the umbrella cost 500
Step-by-step explanation:
Let the cost of the bag be b and the cost of the umbrella be u
Total cost is;
b + u = 2,000 •••••(i)
From the second part of the question;
b = 5u-1000 ••••••(ii)
Substitute ii into i
5u-1000 + u = 2000
6u = 2000 + 1000
6u = 3000
u = 3000/6
u = 500
To get b, substitute the value of u into equation ii
b = 5(500)-1000
b = 2500-1000
b = 1500
