Bobby claims that Peter started with 21 cards. Which statements are true about verifying Bobby’s claim? Check all that apply.
1. Substitute 21 for x in the original equation.
2. Substitute any number for x in the original equation.
3. Bobby’s claim that x = 21 is correct.
4. The result of verifying Bobby’s work is 9 = 9.
5. The result of verifying Bobby’s work is 21 = 21.
Hi There!
Answer:
1. Substitute 21 for x in the original equation.
3. Bobby’s claim that x = 21 is correct.
4. The result of verifying Bobby’s work is 9 = 9.
Step-by-step explanation:
Linear Equation: 1/2 (x - 3) = 9
Bobby wants to substitute x for 21.
1/2 (21 - 3) = 9
1/2 (18) = 9
9 = 9
Bobby's claim is correct.
Hope This Helps :)

Answer:
5 hours
Step-by-step explanation:
19+6=25 1
25+6=31 2
31+6=37 3
37+6=43 4
43+6=49 5
Answer:
5 hours
Step-by-step explanation:
49(total)-19(base charge) = 30(rented money needed). 6 times 5 = 30. So, Katie paid 5 hours. Kind of confusing but trust me. Hope this helps
The total pages in the book are 46.
An equation is a formula that expresses the equality of two expressions, by connecting them with the equals sign =.
Given that, Rosa read 10 pages of a book on Monday. She read 1/3 of the remainder on Tuesday, and she still had 24 pages to read,
Let the total number of pages be x,
Establishing the equation, we get,
10+(x-10) / 3+24 = x
30 + x - 10 + 72 = 3x
92 = 2x
x = 46
Hence, The total pages in the book are 46.

Answer:
There are 46 pages in the book.
Step-by-step explanation:
if she already read 10 pages of the book and the remainder is split into 3rds and she already read 1/3 of the book then the 24 pages get divided by the 2/3 left which equals 12 so each third is 12 pages so 12 x 3 = 36 + 10= 46
There are 46 pages in the book.
What is the correct sequence of steps to solve Mrs. Blake’s equation?
A. Subtract 6h from both sides. Subtract 5 from both sides. Divide each side by –2.
B. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 2.
C. Subtract 4h from both sides. Add 5 to both sides. Divide each side by 2.
D. Subtract 4h from both sides. Subtract 5 from both sides. Divide each side by 6.
Answer:
Option B: Subtract 4h from both sides. Subtract 5 from both sides.Divide each side by 2.
Step-by-step explanation:
So why option B?
When solving equations one of the best method is to bring like terms together to a side (LHS or RHS) of the equation.
What are liked terms? This are numbers or integers with similar structure. From the question the liked terms are 5 and 10, and 6h and 4h.
Going by the workflow described in option B we will see that the end game here was to bring liked terms together.
So lets carry out the workflow step by step:
So for the Babysitters to charge the same amount they have to have worked for 2.5 hours (that is 2 hours 30 minutes)
