<h2>
Step-by-step explanation:</h2>
<u>Ques 1)</u>
The product of 5 and x.
Product of two numbers means that it is obtained by multiplying them.
Hence, the expression so obtained is: 5x
<u>Ques 2)</u>
22% of a
It means that:
22%×a
Also, we know that:
22% =0.22
This means that:
22% of a=0.22×a
i.e.
22% of a=0.22a
<u>Ques 3)</u>
8 more than the product of 6 and n.
The product of 6 and n is given by: 6n
and 8 more than there product will be given by:
8+6n
<u>Ques 4)</u>
Evaluate: 30 − m/6 for m = 30
i.e. we put m=30 in the expression and get the resulting value.
i.e. we have:
30-m/6=30-(30/6)
i.e.
30-m/6=30-5
i.e.
30-m/6=25
<u>Ques 5)</u>
Evaluate ab + c for a= 2, b = 5, c = 4.
i.e. we will put the value of a,b and c in the given expression and find the value.
i.e.
2×5+4= 10+4
i.e.
ab+c=14
Answer:
Step-by-step explanation:
9x - 1 / 2 + 9/2 x = 0.128886 (43)
2 / 5x - 1b = 4/3 - 1 - 1 = 2x (4)
= x1 + 24 - 3/4 + 8
9/3 - 1 x = /3

Answer: 5 friends
Note: if Mariah pays for her own meal, then it would drop to 4 friends.
===========================================================
Explanation:
Add up the amount she earns:
30.25+25.75+11 = 67
Now add up the amounts that she's either in debt or that she spends money on. Ignore the dinner portion for now.
40+2 = 42
She earns $67 total and has to spend $42, without including the dinner portion just yet. That means Mariah has 67-42 = 25 dollars left over.
-------------------
Let x be the number of $5 meals she can buy
So she can spend a total of 5x dollars here. Set this equal to 25 (the amount left over) and solve for x.
5x = 25
x = 25/5
x = 5
She can buy dinner for 5 friends. Or if Mariah is paying for herself as well, then she can buy dinner for 4 friends. It's not clear which scenario your teacher is after, but I'll assume the first scenario.
