Answer:
A. 2 Divided by 3 is 2/3
B. 3 Divided by 2 is 3/2, or 1 1/2
C. 3 Divided by 1/3 is 3/(1/3) = 3*(3/1) = 3*3 = 9
D. 2 Divided by 1/3 is 2/(1/3) = 2*(3/1) = 2*3 = 6
Step-by-step explanation:
Answer:
look at the picture i have sent
Subtract 5x from both sides to make: 3x-4=8. Add four to both sides and divide by three, x=4.
Answer:
1. x = 1, y = -3
2. x = 3, y = 4
Step-by-step explanation:
Here, we want to solve the sets of simultaneous equations;
a) -y = 5x-2
-3y = -5x + 14
substitute 1 into ii
3(5x-2) = -5x + 14
15x - 6 = -5x + 14
15x + 5x = 14 + 6
20x = 20
x = 20/20
x = 1
from;
-y = 5x - 2
y = -5x + 2
y = -5(1) + 2
y = -3
b) -2y = -6x + 10
2y = x + 5
Substitute ii into i
-(x + 5) = -6x + 10
-x - 5 = -6x + 10
-x + 6x = 10 + 5
5x = 15
x = 15/5
x = 3
2y = x + 5
2y = 3 + 5
2y = 8
y = 8/2
y = 4
