Answer: A. 4(8x + 2), and C. 32x + 8
Step-by-step explanation:
Put the equations together and if they have infinitely many solutions they'll both be equal to each other.
CORRECT 4(7x + 2 + x)=4(8x + 2)
7x+2+x=8x+2
8x+2=8x+2 (Infinitely Many Solutions)
CORRECT 4(7x + 2 + x)=32x+8
4(8x+2)=32x+8
32x+8=32x+8
32x+8=32x+8 (Infinitely Many Solutions)
INCORRECT 4(7x + 2 + x)=4(7x + 3)
8x+2=7x+3
8x=7x+1
8x−7x=1
x=1
INCORRECT 4(7x + 2 + x)=28x + 12
4(8x+2)=28x+12
32x+8=28x+12
32x=28x+4
32x−28x=4
4x=4
x=1
Hope this helps, now you know the answer and how to do it. HAVE A BLESSED AND WONDERFUL DAY! As well as a great Valentines Day! :-)

Answer:

Step-by-step explanation:
Given
Initial Level = 340 m
Number of stages = 4
Difference in each stage = 60 m
Required
Determine the depth of the submarine after 4 stages
First, we have to calculate the total distance moved towards the surface of the sea;
This is calculated as



This implies that the submarine moved a total distance of 240 metres;
It;'s new depth is calculated as follows;



<em>Hence, its new depth after 4 stages of rising is 100m</em>
A: 63.75
B: 95.625 dollars
I am pretty sure the correct answer is $146.75. Hope this helps!!!!!!!
