Answer:
A. x < 3
B. X > 9
c. x < 1
d. x < -2
Step-by-step explanation:
For A. 2x+1 < 7
First, subtract 1 from both sides
Then, we will get
2x+1 -1 < 7 - 1
2x < 6
Now, divide both sides by 2
2x / 2 < 6/2
x < 3
For B. X-5 >4
Add 5 to both sides,
Then, we will get
X -5 +5 > 4 + 5
X > 9
For c. 2x+3 <5
Subtract 3 from both sides
2x +3 -3 < 5 - 3
2x < 2
Divide both sides by 2
2x / 2 < 2/2
x < 1
For d. 2x-3 x >2
First, evaluate 2x -3x
2x -3x = -x
Then, 2x-3 x >2 becomes
-x > 2
Now, divide both sides by -1
-x/-1 > 2/-1
x < -2

Answer:
27 purple marbles
Step-by-step explanation:
Let p = purple marbles
r= red marbles
p = 5r-8
p+r = 34
Replace p in the second equation with 5r-8 from the first equation
p+r = 34
5r-8 +r = 34
Combine like terms
6r -8 = 34
Add 8 to each side
6r-8+8 = 34+8
6r = 42
Divide each side by 6
6r/6 = 42/6
r= 7
We want to find p
p+r = 34
p+7 = 34
Subtract 7 from each side
p+7-7 = 34-7
p =27
