Answer:

5(4+6)-72
5x10-72
50-72
-22

Step-by-step explanation:

If you use PEMDAS, the P is for parenthesis.
So first, you do the (4+6) and then multiply it by 5, when you get that answer, do the final step. Subtract 72.

Hope this helped!! <3

Ad libitum [116K]

Answer:

$28360

Step-by-step explanation:

Step one:

Given data

P=20000

rate= 6%

time= 6years

Step two:

compound interest

A=P(1+r)^t

substitute

A=20000(1+0.06)^6

A=20000(1.06)^6

A=20000*1.418

A=$28360

You could interpret them as system of equation and answer the question easily

from A

-4x + y + x + w =1

write in same form from A

as this system has five variables and four of them are unknowns it means the unique solution is not possible

So, det (A) = 0

What is the y and x? write an equation.

solong [7]

$\bf \begin{array}{ccccccccc}
&&x_1&&y_1&&x_2&&y_2\\
% (a,b)
&&(~{{ 1993}} &,&{{ 14220}}~) 
% (c,d)
&&(~{{ 1997}} &,&{{ 9780}}~)
\end{array}
\\\\\\
% slope = m
slope \implies 
\cfrac{\stackrel{rise}{{{ y_2}}-{{ y_1}}}}{\stackrel{run}{{{ x_2}}-{{ x_1}}}}\implies \cfrac{9780-14220}{1997-1993}\implies \cfrac{-4440}{4}\implies -1110$

$\bf \stackrel{\textit{point-slope form}}{y-{{ y_1}}={{ m}}(x-{{ x_1}})}\implies y-14220=-1110(x-1993)
\\\\\\
y-14220=-1110x+2212230\implies y=-1110x+2226450$

A middle school is selling tickets to a play. The number of child tickets sold is half the number of adult tickets sold. They so

Sidana [21]

Answer:

child tickets - 47

adult tickets - 94

Explanation:

since the number of adult tickets sold is twice that of the number of child tickets sold, we can divide 141 into three parts to find the number of child tickets sold.

141 ÷ 3 = 47 (number of child tickets sold)

we can now multiply this by two to find the number of adult tickets sold.

47 × 2 = 94

i hope this helps! :D
