Let
x--------------> a number

we know that
<span>three sets of a sum of a number and four----------> 3(x+4)
t</span><span>he sum of 7 times the same number and 13--------> 7x+13

therefore

</span>(Three sets of a sum of a number and four) are added (to the sum of 7 times the same number and 13) ----------> [3(x+4)] + [7x+3]

[3(x+4)] + [7x+3]------> [3x+12] + [7x+3]=10x+15

the answer is 10x+15

Determine which of the four levels of measurement​ (nominal, ordinal,​ interval, ratio) is most appropriate. monthly temperature
Svetach [21]

Answer:

Interval level of measurement

Step-by-step explanation:

There are four level of measurements; nominal, ordinal, interval and ratio.

Nominal level of measurements separates data into exclusive categories. There is no ranking or order required in the data. Temperature is not divided into categories.

Ordinal level of measurements separates data into exclusive categories like nominal but there is ranking and order required for the data. Temperature doe not require categories or ranking.

Interval level of measurement ranks data where there are differences between units of measure but there is no meaningful zero. For temperature, a zero is not required and the interval between values is interpret-able. For example, the distance between 67 to 67 is the same as distance between 67 to 71, 71 to 75 and 75 to 79 degree f.

One number is 9 more than twice another. If their difference is 22, what is the larger number?
mafiozo [28]
Let, the numbers are: x, y
So, Equations will be: x - y = 22
x = 2y + 9

Substitute the value of x in first equation, 
2y + 9 - y = 22
y = 22 - 9
y = 13

x - 13 = 22
x = 22 + 13 = 35

In short, Larger number would be 35

Hope this helps!

Rewrite the equation below so that it does not have fractions.
bearhunter [10]

Answer:

60+10x=6

Step-by-step explanation:

Hi there!

4+\displaystyle \frac{2}{3} x=\frac{2}{5}

To get rid of the fraction \displaystyle \frac{2}{3}, multiply both sides of the equation by 3 (the denominator):

3(4+\displaystyle \frac{2}{3} x)=3(\frac{2}{5})\\\\3*4+\frac{3*2}{3}x =\frac{3*2}{5} \\\\12+2x =\frac{6}{5}

To get rid of the fraction \displaystyle \frac{6}{5}, multiply both sides of the equation by 5 (the denominator):

\displaystyle 5(12+2x) =5(\frac{6}{5})\\\\5*12+5*2x=\frac{5*6}{5} \\\\60+10x=6

I hope this helps!

Solve s=2(lw+lh+wh) for w
Scilla [17]

                                                                   s = 2(lw + lh + wh)

Divide each side by  2 :                            s/2 = lw + lh + wh

Subtract 'lh' from each side:                s/2 - lh = lw + wh

Combine the 'w' terms:                        s/2 - lh = w(l + h)

Divide each side by (l + h):  (s/2 - lh) / (l + h) = w
