Solve for c.<br> 6c + 14 = -50+ 4+9c
lora16 [44]

Answer:

c=+20

Step-by-step explanation:

6c+14=-50+4+9c

move all terms to the left

6c+14-(-50+4+9c)=0

add all the numbers and variables together

6c-(9c-46)+14=0

We get rid of parentheses

6c-9c+46+14=0

add all the numbers and variables together

-3c+60=0

move all terms containing c to the left, all other terms to the right

-3c=-60

c=-60/-3

c=+20

Hope this helps!!!

The sum of 38 and twice a number x is 124. The value of "x" is 43

- 2x - 5 is equal to – 91.

<u>Solution:</u>

Given that , The sum of 38 and twice a number x is 124.  

We have to find what is - 2x - 5?

Now, according to given information, 38 + 2 × x = 124  

2x + 38 = 124  

2x = 124 – 38  

2x = 86  

x = 43

So, the value of x is 43

<em><u>Now, Evaluating - 2x – 5  </u></em>

Substitute "x" = 43 to evaluate

- 2(43) – 5  

- 86 – 5  = - 91

Hence, the required answer is – 91.

a wheel has a diameter of 15cm. The wheel travels 50 metres. How many revolutions does the wheel complete?
TEA [102]

Answer:

106

Step-by-step explanation:

The diameter of the wheel is 15 cm or 0.15 m.

The circumference of the wheel is 0.15π m ≈ 0.47 m.

So the wheel moves 0.47 m with each revolution.

The wheel travels 50 m, so the number of revolutions is:

(50 m) / (0.47 m/rev) ≈ 106 revolutions.
