Answer:
your wrong lol im sry btw this is a alt XDDD
Step-by-step explanation:
Value of x: 2.5
Value of y: -0.5
-------------------------
To find x:
x + 1 = 3x - 4
-x -x
1 = 2x - 4
+4 +4
5 = 2x
-- ---
2 2
2.5 = x
Check:
2.5 + 1 = 3(2.5) - 4
3.5 = 7.5 - 4
3.5 = 3.5
To find y:
3y = 5y + 1
-5y -5y
-2y = 1
--- ----
-2 -2
y = -0.5
Check:
3(-0.5) = 5(-0.5) + 1
-1.5 = -2.5 + 1
-1.5 = -1.5
Answer:
for a its 9, 3, -6, x<-6
Step-by-step explanation:
If you would like to know how long would it take John to mow the lawn alone, you can calculate this using the following steps:
hours (Jessica) ... a
hours (John) ... b = ?
a + b = 11
b = 4 * a
___________
a + b = 11
a + 4 * a = 11
5 * a = 11 /5
a = 11/5 = 2 1/5 = 2.2 hours
b = 4 * a = 4 * 2.2 = 8.8 hours
The correct result would be 8.8 hours.
I think it’s 4x^2 - 33x + 5/ x if I looked at your question correctly
