What is the first mistake that was made? - 10x + 14 - 2x = 2( -3x - 2)
-10x + 14 - 2x = -6x - 4
-10x - 2x + 14 = -6x - 4
-12x + 14 = -6x - 4
+6x. +6x
6x + 14 = - 4

what is the solution to the equasion 1/2x + 3= 2/3x + 1
Answer:
12
Step-by-step explanation:
1/2x+2=2/3x
2= 2/3x-1/2x
2=4/6x-3/6x
2=1/6x
multiply both sides by 6
x=12
Answer: x = 12
Step-by-step explanation:
1/2x + 3= 2/3x + 1
= 1/2x + 3 - 3 = 2/3x +1 -3
Simplify
= 1/2x = 2/3x -2
= -1/6x = -2
multiply both sides by -6
(-1/6x)(-6) = (-2)(-6)
x = 12

A map of Colorado says that the scale is 1 inch to 20 miles or 1 to 1,267,200. Are these two ways of reporting the scale the same? Explain your reasoning.
Answer:
1,267,200
Step-by-step explanation:
Given that the map reported that the scale is 1 inch to 20 miles.
Recall that there are 63,360 inches in 1 mile, thus, in 20 miles, we have 20 x 63,360 = 1,267,200
Therefore, the scale of 1 inch to 20 miles can also be represented as 1 to 1,267,200

9) Carla's credit card statement showed that she owed $350. She
Thade a payment of $200, then she charged $23 for gasoline She
returned a sweater she had charged earlier for a refund of $35
Then she charged $15 at the bookstore. What is her new balance?
35
Answer:
the answer is -153
Step-by-step explanation:
350-200(she paid off 200$)=150
150+23(she charged her account 23$)=173
173-35(she paid off 35$)=138
138+15(she charged her account 15$)=135
her new balance is -153$ because that is how much she has left to pay off before she reaches 0 then she can gain credit.
Prove that if -5(x + 4) = 70, the x = -18. Write a justification for each step.
Step-by-step explanation:
Let's solve your equation step-by-step.
−5(x+4)=70
Step 1: Simplify both sides of the equation.
−5(x+4)=70
(−5)(x)+(−5)(4)=70(Distribute)
−5x+−20=70
−5x−20=70
Step 2: Add 20 to both sides.
−5x−20+20=70+20
−5x=90
Step 3: Divide both sides by -5.
−5x

9514 1404 393
Answer:
(-9, -3)
Step-by-step explanation:
For x=-9, we have f(x) = 6.
For x=-9, -1/2f(x) = -1/2(6) = -3. The corresponding point is (-9, -3).
A square has an area of 9yd^2. What is the length of each side?
Answer: The side length is 3 yards.
Step-by-step explanation:
To find the area of a square, you have to square one of it's side lengths since they all share the same length. Since we know the area, and we need to find the side length so we just need to find the square root of the area.
[tex]\sqrt{9}[/tex] = 3
The side length is 3 yards.
The length of each side of a square is, 3 yards.
What is mean by Rectangle?A rectangle is a two dimension figure with 4 sides, 4 corners and 4 right angles. The opposite sides of the rectangle are equal and parallel to each other.
We have to given that;
⇒ An area of square = 9 yards²
Now, We know that;
⇒ Area of square = Side²
Let the side of square = a
So, We get;
⇒ a² = 9
⇒ a = √ 9
⇒ a = 3 yards

In training for a swim meet, Logan swam 750 meters in 1.3 of a hour. His swimming partner , Mila swam 2.3 of Logan's distance in 1.4 of a hour. What is Logan's average swimming speed? What is Mila's average swimming speed? Compare Mila's and Logan's swimming speed.
Answer:
Step-by-step explanation:
For Logan:
Logan swam 750m
Logan distance = 750m
Time taken = 1.3×3600
Time taken = 4680
Logan average speed = distance/time
average speed = 750/4680
Logan Average speed = 0.160m/s
Mila swam 2.3 of Logan's distance
Milan distance = 1725m
Time taken = 1.4×3600
Time taken = 5040s
Milan average speed = distance/time
Milan average speed = 1725/5040
Milan average speed = 0.342m/s
Comparing Milan speed with Logan speed:
Difference in speed = 0.342-0.160
Difference in speed = 0.182m/s
This means that Milan speed is 0.182 greater than Logan speed.
