Answer:
28
Step-by-step explanation:
2x+3y=17 --- 1
3x+6y=30 --- 2
x+2y=10
x=10-2y --- 3
Sub 3 into 1,
2(10-2y)+3y=17
20-4y+3y-17=0
3-y=0
y=3 --- 4
Sub 4 into 3,
x=10-2(3)
x=4
Therefore, Answer is (4,3).
Answer:
TS = 22
x = 49
Step-by-step explanation:
(5x-2)/39 = (3x+1)/26
Multiply both sides by 78:
10x-4 = 9x+3
x=7
3x+1 = 22
:::::
(x+5)/36 = 30/20
x+5 = 54
x = 49
Answer:
Hey!
Your answer is...-1.22803363764 !
Step-by-step explanation:
BUT TO MAKE IT MORE PRECISE, YOUR ANSWER SHOULD BE ROUNDED TO 2 Decimal Places WHICH MAKES IT... -1.23!
HOPE THIS HELPS!
You use the rule , y2-y1/x2-x1 , to find the slope so the answer will be = 0-2/4-1 = -2/3
