If you would like to solve the equation a = 2 + 3a + 10, you can do this using the following steps:

<span>a = 2 + 3a + 10
</span>-2 - 10 = 3a - a
-12 = 2a    /2
a = -6

The correct result would be -6.

Answer:

Option 3rd is correct

a = -6

Step-by-step explanation:

Given the equation:

a = 2+3a+10

Like terms are those terms which have same variable to the same power.

Combine like terms we have;

a = 12+3a

Subtract 3a from both sides we have;

a-3a = 12+3a-3a

Simplify:

-2a = 12

Divide both sides by 2 we have;

a = -6

therefore, the value of a is, -6

A school conducts 27 tests in 36 weeks. Assume the school conducts tests at a constant rate. What is the slope of the line that
NeTakaya

Answer:

The slope of the line that represents the number of tests on the y-axis and the time in weeks on the x-axis is \frac{3}{4}.

Step-by-step explanation:

<h3>Definition of slope of a line:</h3>

The slope of a line describes its steepness. In mathematical terms, for a line passing through two points with known coordinates, the slope is defined as the ratio of the change in the y-coordinates to the change in the x-coordinates.

<h3>Formula for the slope of a line:</h3>

Let 'm' represent the slope of a line passing through two points with coordinates (x_{1},y_{1}) and (x_{2},y_{2}). So, according to the definition, the slope of the line can be written as follows,

m=\left|\frac{y_{2}-y_{1}  }{x_{2}-x_{1}}\right|

<h3>Calculation of slope:</h3>

According to the information given in the question, the school conducts 27 tests in 36 weeks.

Now, any point on the x- axis is given by the general form (x,0), where  x  represents any numerical value on the axis. Similarly, any point on the y- axis is given by the general form (0,y), where y represents any numerical value on the axis.

It is given that the time in weeks is represented on the x- axis, so 36 weeks can be represented as coordinates as (36,0). Likewise, the number of tests conducted, i.e., 27 can be represented as coordinates as (0,27).

Now, slope of the line passing through the above mentioned points, using the formula is as follows,

m=\left| \frac{27-0}{0-36} \right|\\m=\left| \frac{27}{-36} \right|\\\\m=\left| \frac{3}{-4} \right|\\\\

Simplifying the mod operator, the slope of the line is found to be \frac{3}{4}.

Hence, the correct option is option A.  \frac{3}{4}.

Find the smallest positive integer that has a remainder of 2 when divided by 4 and remainder of 3 when divided
mestny [16]

Answer:

18

Step-by-step explanation:

Hello

The number is more by three than a multiple of of 5 (i.e 5x +3) and more than 2 than a multiple of 4 (ie 4y+2(

Now 5x+3=4y+2

ie 5x +1 =4y

we need to give the lowest pair of values to x and y such that the last equality is satisfied.

By trial, x = 3 and y = 4

thus the number is 5x+3 =5(3)+3 =18=4y+2 =4(4)+2=18

I hope it has helped you.
