15/60 simplified is 1/4
1/4 is not equal to 3/4
X² = 1/4 ⇒√⇒ x₁ = 1/2, x₂ = -1/2
Answer:

Step-by-step explanation:
1st equation:
3 cups = 3x
3x = 75
x = 25, cup = 25
2d equation
25 + lemon* lemons= 25 + y²
25 + y² = 89
y²= 89 - 25
y²= 64
y = 8, lemon = 8
3d equation
3 circles = 3c
3c = 44
c = 44/3 = 14 2/3
4th equation
25 + 32 + 14 2/3 = 71 2/3
Answer:
X= 7 I hope this helped!
<u>Steps for equation/answer :</u>
1.Divide both sides by 3.
4x+9= 111/3
2.Simplify 111/3 to 37.
4x+9=37
3.Subtract 9 from both sides.
4x=37−9
4. Simplify 37-9 to 28.
4x=28
5. Divide both sides by 4.
x = 28/4
6. Simplify 28/4 to 7
x=7
