3d+16=-2(5-3d) solve equation

strojnjashka [21]

Answer:

The value of d of the given equation is 8.67

Step-by-step explanation:

Given equation as :

3 d + 16 = - 2 × ( 5 - 3 d )

Or, 3 d + 16 = - 10 + 6 d

Or, 16 + 10 = 6 d - 3 d

So , 26 = 3 d

∴ d = $\frac{26}{3}$ = 8.67

Hence The value of d of the given equation is 8.67 Answer

Solve the inequality -5(d-2)>35

chubhunter [2.5K]

Answer:

d < -5

Step-by-step explanation:

Okay, so the equation is -5(d-2)>35

First we have to use distributive property to get rid of the parenthesis.

we do -5(d) --> -5d

then, -5(-2) --> 10

So now we just redo the equation---

-5d + 10 > 35

now you have to isolate d, the variable

First, to isolate you have to get rid of 10. Subtract 10 on both sides.

-5d + 10 > 35

- 10 -10

----------------------

-5d > 25

Then you have -5d > 25. You have to do the opposite operation again to make the d by itself, so you divide -5 on each side.

-5d > 25

----- -----

-5 -5

-5d/-5 is d because the -5's cancel out. 25/-5 is -5. Now, you have to flip the equation because when working with inequalities, you have to flip the symbol.

SO,,, the answer is

d < -5

Hope this helps!!

Clifton ran 6 miles in 39 minutes. At this rate, how much time Clifton takes to run one mile?

slavikrds [6]

Option C: Clifton takes 6 minutes and 30 seconds to run one mile.

Explanation:

Given that Clifton ran 6 miles in 39 minutes.

We need to determine the time it takes for Clifton to run one mile.

To determine the time that it takes for Clifton to run one mile, we shall divide 39 minutes by 6 miles.

Thus, we have,

$\frac{39 \ minutes}{6 \ miles}=6.5 \ minutes$

$=(6+0.5) \ minutes$ -------(1)

To convert 0.5 minutes to seconds, let us multiply the value by 60.

Thus, we have,

$0.5 \times 60= 30 \ seconds$

Thus, substituting in equation (1), we have,

$(6+0.5) \ minutes= 6 \ minutes \ and \ 30 \ seconds$

Therefore, it takes 6 minutes and 30 seconds for Clifton to run one mile.

Hence, Option C is the correct answer.
