3p-8=13-4p
+4          +4
so now you got 7p-8=13
                            +8  +8
and now you have 7p=21 and how many times does 7 go in to 21 and you should get p=3 and there you go

The choir is selling candy bars to raise money for a trip they sell each candy bar for $5 there are 7 candy bars in each box and
Reika [66]

Answer:$2800

Step-by-step explanation: Lets first figure out how much money a box of candy bars is worth. We know that each candy bar is worth $5 and that there are 7 candy bars per box. We can multiply 7*5 to figure out that each box is worth $35.

Now lets figure out how many boxes can be sold each day. Each student can sell two boxes a day. 5 students selling 2 boxes each is 5*2= 10 boxes total sold a day.

Now finally we use what we found to figure out the amount of money made per day. We know that there are 10 boxes being sold and that each box makes them $35. We just multiply 10 boxes by $35 to get $350 dollars each day.

Since they sell for 8 days we just multiply 8*$350 to get $2800.

vichka [17]
75d+8w+25
Part A)
75 and 8 are coefficients because coefficients are the numbers before and multiplied to the variable.
d and w are variables because variables aresymbols to represent the unknown numbers.
25 is the constant because constants are not affected by the variable.
Part B)
75d+8w+25
75(5)+8(48)+25 replace the variables
375+384+25      multiply
        784                add
Part C)
No, because his stipend is a constant, and constants are not affected by the variable.

Compute<br><br> 8*4-4 divided by 2 +1
iragen [17]

Solution of 8 x 4 - 4 divided by 2 +1 is 9.33

<h3><u>Solution:</u></h3>

Given that,

8 x 4 - 4 divided by 2 +1

We have to compute the above equation

Let us write the given sentence mathematically:

\rightarrow \frac{8 \times 4-4}{2 + 1}

Let us BODMAS rule to solve the above expression

According to Bodmas rule, if an expression contains brackets ((), {}, []) we have to first solve or simplify the bracket followed by of (powers and roots etc.), then division, multiplication, addition and subtraction from left to right.

So let us first perform multiplication of 8 and 4 in numerator

\rightarrow \frac{32 - 4}{2 + 1}

Now we can perform addition of 2 and 1 in denominator

\rightarrow \frac{32-4}{3}

Now we can perform subtraction of 4 from 32 in numerator

\rightarrow \frac{28}{3}

Now perform division of 28 by 3

\rightarrow \frac{28}{3} = 9.33

Thus solution of 8 x 4 - 4 divided by 2 +1 is 9.33
