Answer:
0.128
Step-by-step explanation:
X+Y=6
X-Y=10
Step-by-step explanation:
x + y = 6 ...................equation 1
x - y = 10 ..................equation 2
Solving equation 1 and 2
x + y = 6
x -y =10
2x = 16
x = 16 /2
Therefore x = 8
Now
putting x = 8 in equation 1
8 + y = 6
y = 6 -8
y = -2
hope it was helpful :)
Answer:
x=8 and y= -2
Step-by-step explanation:
x+y=6
x-y=10 + ( add them together)
-----------------
2x=16 ( substitute/ plug x back in )
x=8
8+y=6
8-y=10
y=-2
Answer:
3/4
Step-by-step explanation:
Question: Find the value of the sine for <A
C= 80m
B= 60m
A= ?
Well, since there are 3 sides you divide by three, only 2 sides are given so first add them,
80+60= 140
140/3= 46.6 also 46 6/10
Then divide by 62.13 because 140- 77.87 is that
It would lead you with 3/4

Standard form : Ax+By=C
Answer:
-x + 5y = 12
Step-by-step explanation:
Eliminate the fractional coefficient by multiplying both sides by 5:
5y - 15 = x - 3
Combine the constants: 5y = x + 12
Subtract x from both sides: -x + 5y = 12 This is in standard form
