Answer: 72

Step-by-step explanation:

From the question, we are informed that Mary Beth needs a 90% on her final exam to get an A for the quarter and that the exam has 80 questions.

The number of questions does that Mary need to answer correctly in order for her to get an A would be 90% of 80. This will be:

= 90% × 80

= 90/100 × 80

= 72

She must get 72 to get a A.

Answer:

(x, y) = (7, 5/3)

Step-by-step explanation:

2x - 3y = 9

5x - 3y = 30

(5x-3y) - (2x-3y) = 30 - 9

5x-3y - 2x +3y = 21

3x = 21

x = 7

So, substituting the value of x into the first equation, we get 2*7 - 3y = 9. Simplifing, we get,

14 - 3y = 9

-3y = -5

y = 5/3

Answer:

Step-by-step explanation:

Let's take the unit ratio of weight to length:

[tex] \frac{15 \: pounds}{4 \: feet} = 3.75 \frac{pound}{feet}[/tex]

Now that we have the unit ratio, let's multiply it to the similar pipe which is 7 feet long.

[tex]3.75 \frac{pounds}{feet} \times 7 \: feet = 26.25 \: pounds[/tex]

Answer:

24 scoops of iced tea

Step-by-step explanation:

Well, the way that I am going to solve this question is by calculating how many 1/4 cups she needs to get 1 cup and then multiply that by 6.

1/4 x 4 = 1

So 4 times 6 equals 24.

In conclusion, she needs 24 scoops

1/4 x 24 = 24/4. 24 divided by 4 equals the 6 cups Anna needs

Answer:

All real numbers are solutions (hope that helps)

Step-by-step explanation:

12x+1=3(4x+1)−2

Step 1: Simplify both sides of the equation.

12x+1=3(4x+1)−2

12x+1=(3)(4x)+(3)(1)+−2(Distribute)

12x+1=12x+3+−2

12x+1=(12x)+(3+−2)(Combine Like Terms)

12x+1=12x+1

12x+1=12x+1

Step 2: Subtract 12x from both sides.

12x+1−12x=12x+1−12x

1=1

Step 3: Subtract 1 from both sides.

1−1=1−1

0=0
