20+x over 8+12/2=1 what does x equal

Mathematics
1 answer:
stepladder [879]3 years ago
8 0

Answer:

x = -6

Explanation:

Simplify

1/14x + 10/7 = 1

Subtract 10/7 from both sides

1/14x + 10/7 - 10/7 = 1 - 10/7

1/14x = -3/7

Multiply both sides by 14

1/14x*14 = -3/7*14

x = -6

Given g(x) = f(x) + k. Identify a value of k that transforms finto g. Round your answer to the nearest integer. g 2 X - 14 -2 O
Keith_Richards [23]

Answer:

  • k = -5

Step-by-step explanation:

We can see the lines are parallel

The function f(x) has y-intercept of 2 at point (2, 0) and the function g(x) has y-intercept of -3 at point of (-3, 0)

If f(x) = mx + 2, then g(x) = mx - 3

<u>The value of k is the difference of y-intercepts as slopes are same due to lines being parallel:</u>

  • g(x) = f(x) + k
  • k = g(x) - f(x)
  • k = (mx - 3) - (mx + 2)
  • k = -3 - 2
  • k =  -5

So the answer is k = -5

Tommy is thinking of a number between 800 and 900 He divides it by 4 and there is a remainder of 1 He divides it by 5 and there
Finger [1]

Answer:

841

Step-by-step explanation:

If the number is divided by 4 and the remainder is 1, the last digit must be 1, 3, 5, 7 or 9.

If the number is divided by 5 and the remainder is 1, the last digit must be 6 or 1.

So we already know the last digit must be 1.

The numbers between 800 and 900, with last digit 1, that divided by 6 have a remainder of 1 are:

811, 841, 871

The numbers between 800 and 900, with last digit 1, that divided by 7 have a remainder of 1 is just 841

So Tommy's number is 841.

An empty cup in the shape of a cylinder is being filled with water . The cup is filled at constant rate . The table below shows
KatRina [158]
<h2>Explanation:</h2><h2></h2>

Hello! Remember you have to write complete questions in order to get good and exact answers. I'll help you to understand this problem, but I have to assume some things.

We know that the empty cup in the shape of a cylinder is being filled with water. Suppose the volume of this cylinder is:

V=450cm^3

Suppose that the cup is filled at a constant rate of s=50cm^3/s, so in 7 seconds the cup is filled the following amount:

V'=50\times 7=350cm^3

So this represents the following percentage:

\frac{V'}{V}\times100=\frac{350}{450}\times 100=77.78\%

Finally, after 7 seconds the cup is 77.78% filled
