Answer: \frac{1}{2} I+7

Step-by-step explanation:

marta # books = ?

lucy # books = I

Marta has 7 more books than lucy. This means whatever lucy has, marta has 7 more of:

I + 7

then, marta also has half as many books as lucy meaning the final expression is:

\frac{1}{2} I+7

Answer:

M= 1/2(x)+7

Step-by-step explanation:

Let M = Martha.

Let X = Number of Lucy's blocks.

Martha has half the amount as Lucy  - 1/2(x)

Then 7 more than that - 1/2 (x) + 7

Answer:

A) answer c ; B) X+3.7=15.3 ; C) 15.3 - 3.7 = 11.6 ---> 11.6+3.7=15.3

Step-by-step explanation:

Solution for A: First you have to look for the line underneath the bar says 15.3 as this will represent the total amount of liters in the bucket altogether. This would be bar c since we also know that we have 3.7 liters added but are missing the amount that was previously inside the bucket.

Solution for B: Let X resemble the unknown amount of water. To solve B, we need to write an equation. We know that there was already an amount of water in the bucket prior to us pouring more in so X is our first addend. We then added 3.7 liters of water to the unknown amount so that is our next addend giving you X+3.7=15.3

Solution for C: Now that we know our equation, we do the inverse operation (subtraction) in order to figure out the missing amount of water. This means we do

15.3 - 3.7 = 11.6

Find the value of x. Write your answer as a simplified radical if necessary.
Andreas93 [3]

Answer:

x=5

Step-by-step explanation:

The right angle opposite is the hypotenuse

The 30° is the opposite

SohCahToa

Soh = Sin because you got Opposite and Hypotenuse (because you're trying to find the side, you'd do the opposite of dividing, which is times)

10×sin(30)=5
