sdas [7]

Answer:

Mia's test score is 44 if she got 3 questions wrong.

Mia's test score is (50-2x) if she got x questions wrong.

Step-by-step explanation:

It is given that, Mia is taking a multiple choice test with a total of 50 points available. Each question is worth exactly 2 points.

If she got 3 questions wrong, then

Deducted marks $=2\times 3=6$

Marks obtained by Mia = Total marks - Deducted marks

$=50-6$

$=44$

So, Mia's test score is 44 if she got 3 questions wrong.

If she got x questions wrong, then

Deducted marks $=2\times x=2x$

Marks obtained by Mia = Total marks - Deducted marks

$=50-2x$

So, Mia's test score is (50-2x) if she got x questions wrong.

muminat

Answer:

The number of quarters in total = 16 quarters

The number dimes = 32 dimes

Step-by-step explanation:

The given information are;

The total amount of money in held = $7.20

The denomination of the money held = Dimes and quarters

The number dimes = 2 × The number of quarters

Given that a dime = 10 cents = $0.1

A dollar = 25 cents = $0.25

Let the number of quarters in the sum of money = X

Therefore, we have;

X × $0.25 + 2 × X × $0.1 = $7.20

X × $0.25 + X × $0.2 = $7.20

X × $0.45 = $7.20

X = $7.20/$0.45 = 16

Therefore, the number of quarters = 16

The number of quarters in total = 16 quarters

The number dimes = 2 × The number of quarters = 2 × 16 = 32 dimes

The number dimes = 32 dimes.
