Step-by-step explanation:
Samuel's exit ticket is correct, because he multiplied both sides of the equation by seven, using the Multiplication Property of Equality to justify how he got from the first step to the second step. Selma's exit ticket is correct, because she subtracted three from both sides of the equation, using the Subtraction Property of Equality to justify how she got from the first step to the second step. Samuel's exit ticket is correct, but Selma's is incorrect, because she solved the problem in the wrong order. Selma's exit ticket is correct, but Samuel's is incorrect, because he solved the problem in the wrong order. Both students used the properties correctly to justify their correct solutions to the equation. Neither Samuel's or Selma's exit tickets are correct. Neither student used the properties correctly, even though their solutions are true.

how do you identify a perfect square trinomial? give an example
Answer:
Any time you take a binomial and multiply it to itself, you end up with a perfect square trinomial. For example, take the binomial (x + 2) and multiply it by itself (x + 2). The result is a perfect square trinomial.

The area of a door is 3024 square inches. If the length of the door is 48 inches longer than the width of the door, what is the width of the door?
Answer:
The width of the door is 36 inches
Step-by-step explanation:
The given parameters are;
The given area of the door = 3024 in.²
The length of the door = 48 + The width of the door
Let W represent the width of the door
Therefore, we have;
The length of the door = 48 + W
The area of the door = The length of the door × The width of the door
∴ By substitution, the area of the door = 3024 = W × (48 + W)
3024 = W × (48 + W) = 48·W + W²
48·W + W² = 3024
∴ 48·W + W² - 3024 = 0
Rearranging, we get;
W² + 48·W - 3024 = 0
By trial and error, we have;
(W + 84)×(W - 36) = 0
Therefore, given that the width of the door is a natural number, we have;
The width of the door, W = 36 inches
Find the HCF of 30 and 45.
Answer:
15
Step-by-step explanation:
Since 30 and 45 are relatively small numbers, it's not a big deal to list every single one of their common factors.
Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30
Factors of 45: 1, 3, 5, 9, 15, 45
Now that we have a list, it's easy to see which number is the highest common factor, which is, of course, 15.
Answer:
HCF of 30 and 45 is 15.
Step-by-step explanation:
Factors of 30 : 1, 2, 3, 5, 6, 10, 15, 30.
Factors of 45 : 1, 3, 5, 9, 15, 45.
Common Factors : 1, 3, 5, 15
Highest Common Factor : 15
i need help. i am confused.
Answer:
Step-by-step explanation:
2(4z+3+3z)=174
7z+3=174/2=87
7z=87-3=84
z=84/7=12
WX=3z=3×12=36 units
Answer:
36 units
Step-by-step explanation:
[tex]2(4z + 3 + 3z) = 174 \\ \\ (7z + 3) = \frac{174}{3} \\ \\ 7z + 3 = 87 \\ \\ 7z = 87 - 3 \\ \\ 7z = 84 \\ \\ z = \frac{84}{7} \\ \\ z = 12 \: \\ \\ WX = 3z \\ \\ WX \: 3 \times 12 \\ \\ WX = 36\: units[/tex]

Suppose Destiny and Megan volunteered to bake cupcakes for a bake sale to raise money for
their school. Destiny works 1.2 times as fast as Megan. When they work together, they can
bake 18 cupcakes in 44 minutes. How long would it take Destiny to bake 18 cupcakes if she
were working alone? Choose the closest answer.
Hint
A 1 hour and 50 minutes
B 1 hour and 21 minutes
C 54 minutes
D 1 hour and 34 minutes
Answer:
It’s A 1 hour and 21 minutes
Step-by-step explanation:
A group of tourists is determining the order in which to visit national landmarks in Washington, DC. The group contains 200 people. Of those people, 150 are adults, and 50 are children. A random sample of tourists in the group is chosen. Surveying the random sample produced a representative sample of the population. Which was most likely true of the representative sample?
Answer: the representative sample contained more adults than children
Step-by-step explanation:
The options are:
a. The representative sample contained all 200 tourists.
b. The representative sample contained more adults than children.
c. The representative sample contained more children than adults.
d. The representative sample contained an equal number of adults and children.
Number of adults = 150
Number of children = 50
Total = 150 + 50 = 200
Probability of choosing an adult = 150/200 = 0.75
Probability of choosing a child = 50/200 = 0.25
The above shows that the representative sample contained more adults than children. This can be seen in the explanation above as number of adults is thrice that of children.
