How many solutions does 4x + 2(x – 3) = 4x + 2x – 11 have?
Answer:
4x + 2(x – 3) = 4x + 2x – 11
4x + 2x - 6 = 4x + 2x - 11
6x - 6 = 6x - 11
-6 = -11
There is no solution because -6 does NOT equal -11
Answer:
0 solution
Step-by-step explanation:
4x + 2(x – 3) = 4x + 2x – 11
Solve the parentheses:
4x + 2x - 5 = 4x + 2x - 11
Subtract 2x from both sides:
4x - 5 = 4x - 11
From what you can already see that those two expressions does not equal to each other. Let’s continue solving to confirm:
(Subtract 4x on both sides)
-5 = -11
There are 0 solutions

-5 + 5 (x-7) = -40 + 5x
Answer:
0=0
This means it is true for all x
Step-by-step explanation:
-5 + 5 (x-7) = -40 + 5x
Step 1: 5x-40=-40+5x
Step 2: Add 40 to both sides
5x-40+40=-40+5x+40
Step 3: Simplify
5x=5x
Step 4: Subtract 5x from both sides
5x-5x=5x-5x
Step 5: Simplify
0=0
Both sides are equal
True
Or
True for all x
Answer : 0=0

Mai’s family is traveling in a car at a constant speed of 65 miles per hour.
At that speed, how long will it take them to travel 200 miles?
Answer:
3 hours and 5 minutes
Step-by-step explanation:
d/st
s=65. d=200
200/65=3°4°36.92
MAKE SURE TO USE DEGREE BUTTON ON CALCULATOR
therefore, 3 hours and 5 minutes
It take 3hours to travel 200miles at the speed of 65 miles per hour.
What is speed?Speed is the time rate at which an object is moving along a path.
Formula for finding speed[tex]speed = \frac{distance}{time}[/tex]
According to the question
We have
speed = 65 miles per hour
distance = 200miles
Therefore,
The time taken by them to travel 200 miles at speed 65 miles per hour is calculated as:
[tex]time=\frac{200}{65}[/tex]

how can you use a mental math and the inverse property of addition to find the sum [5.5 + (-2.3)] + (-5.5 + 2.3)?
Answer: it is 0
Step-by-step explanation:
[5.5+(-2.3)] + (-5.5+2.3)
We can multiple (-5.5+2.3) by -1 so that it equals the first expression
[5.5+(-2.3)] + (-1)[5.5+(-2.3)]
Then, we change the + to -
[5.5+(-2.3)] - [5.5+(-2.3)]
since we are subtracting the same value, the answer is 0.

(8 x 22) x 2 = 352
96 + 264 + 352 = 742
Answer:
712 cm^2
Step-by-step explanation:
Surface area
Base and Top .......... 2 (8*6) = 96 (cm*2)
2 sides .......... 2 (22*6) = 264 (cm^2)
Front and Back ......... 2 (8*22) = 352 (cm^2
Total 96+264+352 = 712 cm^2
