Answer:

p = \frac{7}{5}

Step-by-step explanation:

change the mixed number to an improper fraction

- 2 \frac{1}{7} = - \frac{15}{7}, hence

- \frac{15}{7} p = - 3 ( multiply both sides by 7 )

- 15p = - 21 ( divide both sides by - 15 )

p = \frac{-21}{-15} = \frac{7}{5}

After substituting, what is the first operation performed when evaluating 5 + (9 x minus 3) divide 2 for x = 5? addition multipl
ludmilkaskok [199]

Answer:

<h2>Multiplication.</h2>

Step-by-step explanation:

The given expression is

5+(9x-3) \div 2

For x=5, we have

5+(9(5)-3) \div 2

Notice that the first operation we need to do is multiplication, because that's the right order of operations when we solve these kind of expressions.

5+(45-3) \div 2

Then, we subtract

5+42 \div 2

Now, we divide

5+21

Finally, we sum

26

Therefore, the right answer is multiplication.

kelly takes pam shopping for new clothes. shirts cost $12 and pants cost $21. Pam spends a total of $240 on 14 new items. how ma
ArbitrLikvidat [17]
Let’s call the amount of pants x and the amount of shirts y.
12y + 21x = 240
y + x = 14 which could be changed to x= 14-y

now you plug it into the first equation
12y + 21 (14 - y) = 240
12y + 294 - 21y = 240

add the similar terms
12y - 21y = 240 - 294
-9y = -54

cancels the minus signs on both sides
9y = 54
y= 6

now you plug y = 6 into the equation x = 14-y
x = 14 - 6
x = 8


answer: Pam bought 8 pants and 6 shirts
