To solve the equation x - 15 = 19, you can add 15 to both sides of the equation to isolate x:
x - 15 + 15 = 19 + 15
This simplifies to:
x = 34
So the correct answer is B.34.
For the second question, you are given that Brandon owns nearly two times as many CDs as Ingrid, and Brandon owns 56 CDs. To estimate the number of CDs Ingrid owns, you can set up an equation:
n = 2 * 56
Simplifying this equation:
n = 112
So the correct answer is C.n = 56; about 112 CDs.
To solve the equation x - 15 = 19, you need to isolate the variable x. You can do this by adding 15 to both sides of the equation:
x - 15 + 15 = 19 + 15
x = 34
So, the correct answer is B.34.
To estimate the number of CDs Ingrid owns based on the given information, we can set up an equation based on the fact that Brandon owns nearly two times as many CDs as Ingrid. Let's call the number of CDs Ingrid owns n:
Brandon's CDs = 2n
Since Brandon owns 56 CDs, we can write this as:
2n = 56
To find an estimate of the number of CDs Ingrid owns, we need to solve this equation for n. Divide both sides by 2:
2n/2 = 56/2
n = 28
So, the correct answer is D. 2n = 56; about 28 CDs.
