Answer:
23/24
Step-by-step explanation:
1/8 + 5/6
The common denominator is 24
1/8 *3/3 = 3/24
5/6*4/4 = 20/24
3/24 + 20/24
23/24
277,200 is the one that it can round up to 277,300 and the least number too
Answer:
47/7, -9/14
Step-by-step explanation:
first you'd solve for x then substitute then find y then substitute the x into the y equation and bam
Answer:
The equation of the line is: y=2x + 3
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
