Now, we will put t=3.11 to find 5t.

The value of 5t will be 15.55

the value is 15.55

Hi there! Let's start off with PEMDAS. It would appear that there are no parentheses or exponents, so let's get to that | Absolute Value |. -4 + 0 is -4, but because it's an absolute value, it'll become 4. The problem should read as 6/2*4. Let's move on to Multiplication/Division. 6/2 is 3, and multiplying 3 by 4 is 12.

Then find the total cost of the item.

Serena spent $8.20 buying cupcake ingredients. At the school bake sale she charged $0.75 per cupcake. If she made a profit of $14.30, how many cupcakes did she sell?


What is the equation?
14.30 - 8.20 = 0.75c
8.20 + 0.75c = 14.30
0.75c - 8.20 = 14.30
14.30 - 0.75c = 8.20

Answers

Answer:

27. C

28. D

Step-by-step explanation:

The average of all grades in his fencing class, including the upcoming one, (all grades summed up divided by the amount of grades) must be equal to 86 (percent), hence C is the right answer for 27.

Solving this equation gives:

[tex]\frac{75+88+62+100+x}{5} = 86\\325 + x = 86 \cdot 5\\x = 430 - 325 = 105[/tex]

So D is the right answer for 28.

27 is c And 28 is d.
