Elan Coil [88]3 years ago

Answer:

1, 3, 4, 5, 6 are all correct

Step-by-step explanation:

1. x - 2 = 0

+2 +2

solution: x = 2

3. 5 - x = 3

-5 -5

-x = -2 (divide both sides by -1 because x equals 1. A negative divided by a negative equals a positive)

solution: x = 2

4. 10 = 5x (you divide 5 on both sides to get x by itself) 10/5 equals 2 so x=2

5. 1/2x = 1 (you divide both sides so you flip the fraction 2/1 is 2 and 2x1 = 2 so the answer is x=2

6. x^3 = 8 (2x2x2) is equal to 8 so x=2

Answer:

1, 3, 4, 5, 6

Step-by-step explanation:

2 - 2 = 0

2 + 2 = 4, not 2

5 - 2 = 3

10 = 5(2)

1/2(2) = 1

2^3 = 8

3x=-5y<br> 6x-7y=17 <br> Solve the equation
love history [14]
3x = -5y -------------- (1)
6x - 7y = 17 --------- (2)

From (1):
3x = -5y
x = -5/3 y ---------- sub into (2)

6 (-5/3 y) - 7y = 17
-10y - 7y = 17
-17y = 17
y = -1 ------------ Sub into (1)
3x = -5 (-1)
3x = 5
x = 5/3

Ans: x = 5/3, y = -1

irina1246 [14]

Answer:

22 pounds

Step-by-step explanation:

c+s=52, c = 52-s

3c+5s=200

3(52-s) +5s = 200

156 - 3s +5s = 200

5s-3s = 200-156

2s = 44

Shrimp = 44/2 = 22 pounds

What is the distance between point R (−1, 7) and point T (−7, 7) ?
zepelin [54]
You can use the distance formula to find the distance between any two points ion the plane. In this case, look carefully at the coordinates:
R(-1, 7) and T(-7, 7), Notice they both have y-coordinate 7. That means they are both on the same horizontal line. To find their distance, just subtract -7 from -1 and take the absolute value.

|-1 - (-7)| = |-1 + 7| = |6| = 6

The distance is 6 units
