+ 10x + 13 = 4

Answers

Answer 1

Answer:

[tex]x = -1[/tex]

Step-by-step explanation:

Equation: [tex]1+10x+13=4[/tex]

Step 1: Balance both parts of the equation.

[tex]1+10x+13=4[/tex]

[tex](10x)+(1+13)=4[/tex]

[tex]10x+14=4[/tex]

[tex]10x+14=4[/tex]

Step 2: Reduce 14 from both parts of the equation.

[tex]10x+14-14=4-14[/tex]

[tex]10x= -10[/tex]

Step 3: Split both sides by 10, because [tex]\mathrn {10x = -10}[/tex].

[tex]\frac{10x}{10} = \frac{-10}{10}[/tex]

[tex]10 / -10 = -1[/tex]

Therefore, x = -1.

Answer:

[tex]\huge\boxed{2329 \ \text{pounds}}[/tex]

Step-by-step explanation:

In order to solve this equation, let's see what we already know.

We know two points on the graph which we can use to find the slope

That's about it.

However, this can come useful to find the slope between the two points, which is the slope for the entire graph (since this is linear). The slope between two points is usually defined as [tex]\frac{\Delta y}{\Delta x}[/tex] (change in y / change in x). Our two points are (18, 2017) and (48, 2212).

The change in y between our two points is [tex]2212-2017 = 195[/tex], and the change in x is [tex]48 - 18 = 30[/tex]. Our slope will then be [tex]\frac{195}{30}[/tex], which comes out to be approximately 6.5. Therefore, our slope is 6.5.

Now that we know the slope, we can substitute inside our equation in slope intercept form.

[tex]y = 6.5x+b[/tex]

We have yet to find b, the y-intercept (how much the plane itself weighs). To find b, we can substitute a point on the graph into the equation and solve for b. We know that the point (18, 2017) is on the graph so let's use that.

[tex]2017 = 6.5 \cdot18 + b[/tex] [tex]2017 = 117 + b[/tex] [tex]1900= b[/tex]

Now that we know our y-intercept is 1900, we can create our equation by using the slope and the y-intercept.

[tex]y=6.5x+1900[/tex]

Finally, to find the weight of the plane with 66 pounds of fuel, we can substitute 66 inside this equation as x.

[tex]y = 6.5 \cdot66+ 1900[/tex] [tex]y = 429+1900[/tex] [tex]y=2329[/tex]

So the plane weighed 2329 pounds with 66 gallons of fuel.

The lines (m-2)x+y=2 and mx+2y=k intersect at (2,8). Find the values of m and k

Answers

Answer:

m = - 1, k = 14

Step-by-step explanation:

The coordinates of the point of intersection (2, 8 ) satisfy both equations.

Substitute x = 2, y = 8 into the equations and solve for m and k

(m - 2)x + y = 2

2(m - 2) + 8 = 2

2m - 4 + 8 = 2

2m + 4 = 2 ( subtract 4 from both sides )

2m = - 2 ( divide both sides by 2 )

m = - 1

and

mx + 2y = k

- 1(2) + 2(8) = k

- 2 + 16 = k

14 = k

Then m = - 1 and k = 14

Increase £101 by 16%
Give your answer rounded to 2 DP.

Answers

the answer is £84.84 i think

If we increase £101 by 16% then it would be £117.16

What is percent?

"It is the number that can be expressed as a fraction of 100."

For given example,

we need to increase £101 by 16%

First we find the 16 percent of £101

16% of £101 = 101 × (16/100)

16% of £101 = 101 × 0.16

16% of £101 = £16.16

So,  if we increase £101 by 16% then it would be,

£101 + £16.16 = £117.16

Therefore, if we increase £101 by 16% then it would be £117.16

what's the value of x?​

if your teacher says

Answer:

x = 75

Step-by-step explanation:

The angle vertically opposite 50° is also 50° ( congruent )

The sum of the 3 angles in a triangle = 180°

Subtract the sum of the 2 angles from 180° for x

x = 180° - (50 + 55)° = 180° - 105° = 75°

if the median of data Carranged

48, 48, 50 is 40 then find value of
X​

Answers

Answer:

35

Step-by-step explanation:

If the median of data (arranged in ascending order) 31,33,35,x,x+10,48,48,50 is 40,then find value of x.

Solution:

The median of a data is the middle number after the numbers from the data have been arranged either from least to greatest or from greatest to least. For an even number of data, the median is the average of the middle two numbers.

The data arranged in ascending order is:

31,33,35,x,x+10,48,48,50

SInce the data has an even number (8), the median is the average of the middle two numbers.

Median = average of x and x + 10

[x + (x + 10)] / 2 = median

[x + (x + 10)] / 2 = 40

x + x + 10 = 80

2x + 10 = 80

2x = 70

x = 70/2

x = 35

How to illustrate the graph?

A diagram or pictorial representation that organizes the representation of data or values is known as a graph. The relationships between two or more things are frequently represented by the points on a graph.

Mike's grade point average for the second quarter appears to be three times higher than for the first. The vertical scale's intervals should be adjusted to make them uniform. In this case, the correct option is A.
