Answer:
In total you can buy 3 snacks and ride 4 rides.
Step-by-step explanation:
$2 per ride
$5 for snacks
The equation here is $2r + $5s = $23
First I found out how many times I could multiply 5. First I though 4 but 2 doesnt go into the remaining 3, so I lowered it down to 15 which is 3.
So s = 3
Now our equation is 2r + 15 = 23
Subtract 23 - 15 = 8
Now divide
r = 8 / 2
r = 4
Answer:
a) x = -1.5
b) x = 1
Step-by-step explanation:
For problem a, you can start by subtracting 3x from both sides to gather all the like terms together:
7x + 5 = 3x - 1
-3x -3x
4x + 5 = -1
Next, to get the coefficients on one side, you subtract 5 from both sides:
4x + 5 = -1
-5 -5
4x = -6
Now, you divide by 4 on both sides to isolate x:
x = -6/4 = -1.5 --- > x = -1.5
For problem b, you start by subtracting 3x from both sides(kinda like problem a):
5x + 12 = 3x + 14
-3x -3x
2x + 12 = 14
Next, you can subtract 12 from both sides, isolating the "x term".
2x + 12 = 14
-12 -12
2x = 2
Lastly, you can divide by 2 to get x:
x = 1
They are equal.
2/6 = 1/3
1 * 2 = 2
-------
3 * 2 = 6
do you see it?
