Given equation :

${\qquad \sf \dashrightarrow{ 56= 7v + v }}$

We can rewrite the equation as :

${\qquad \sf \dashrightarrow{ 7v + v = 56 }}$

Adding like terms :

${\qquad \sf \dashrightarrow{ 8v = 56 }}$

Dividing both sides by 8 :

${\qquad \sf \dashrightarrow{ \dfrac{8v}{8} = \dfrac{56}{8} }}$

${\qquad \bf \dashrightarrow{ v = 7 }}$

Henceforth,

The value of v is 7.

Mario tried to solve an equation step by step.

Zarrin [17]

Answer:

Step 2

Step-by-step explanation:

Mario made a mistake in Step 2 when substracting $\frac{1}{3}$ from $\frac{4}{3}$ . When substracting his result ended up being $\frac{2}{3}$ but it is actually....

$\frac{4}{3} - \frac{1}{3} = \frac{4-1}{3} = \frac{3}{3} = 1$

so the right answer is $q = 1$

Y=-2x + 2 make a table of values

butalik [34]

Answer:

Step-by-step explanation:

The negative sign in y = -2x + 2 tells us immediately that the y intercept of the graph of this function is (0, 2). If we start at (0, 2) and increase x by multiples of 1, y decreases by 2 in each case (the slope of this line is -2). Thus, we begin a table as follows:

x y = -2x + 2

0 2

1 -2(1) + 2 = 0

2 -2(2) + 2 = -4 + 2 = -2

and so on:

x y = -2x + 2

0 2

1 0

2 -2

Person A leaves his home to visit his cousin, person B who lives 76 miles away. He travels at an average rate of 44 miles per ho

MrRa [10]

Answer:

There are going to meet half a hour after person B leaves.

Step-by-step explanation:

The first step to solve this problem is model the position equation for both person A and person B. It can be done by a first order equation.

I am going to say that the positive direction is from the person A to the person B. So, A starts at the position 0 and B at the position 76.

The first step is to find the equation of the position of person A

The initial position of A is 0 and he travels 44 miles per hour in the direction of B, so to the positive diretion. So, the position S of person A is

$S_{A}(t) = 44t$ ,

where t is the time in hours.

Now we have to find the equation of the position of person B

The initial position of B is 76 and he travels 64 miles per hour in the direction A, so in the negative direction. The position S of person B is

$S_{B}(t) = 76 - 64t$

Now we have to restart the time from the moment the person B leaves her house.

It happens at 0.5h, at this moment the person A is at the position

$S_{A}(0.5) = 44*(0.5) = 22$

So, from this moment, the equation of the position of A is:

$S_{A}(t) = 22 + 44t$

They will meet at the instant t when

$S_{A}(t) = S_{B}(t)$

$22 + 44t = 76 - 64t$

$108t = 54$

t = 0.5h

There are going to meet half a hour after person B leaves.

13) The diameter of a plant cell is 1.26 m and the length of a bacterium is 5.1 m. Compare their diameters. (WILL MARK BRANLIEST

kolezko [41]

Answer:

The diameter of the bacterium is 4.05 times the diameter of the plant cell

Step-by-step explanation:

The given parameters both represent diameters

Plant Cell P = 1.26m

Bacterium B = 5.1m

First write out both expressions:

P = 1.26

B = 5.1

Divide B by P

5.1 / 1.26 = 4.04762 Round to 4.05

Multiply both side by P

P * B/P = 4.05 P

B = 4.05 P

This shows that the diameter of the bacterium is 4.048 times the diameter of the plant cell.
