Answer:
25
Step-by-step explanation:
Since AC is similar to CE, we can say that they have equal lengths. We are given CE, DE, and BC. To solve this, we can solve for the length of CE (equal to AC) and then subtract that from BC.
To solve for CE, we are given DE and CE. We know that DE is 1/2 of CE because D is the midpoint of CE. Therefore,
7x-1 = 1/2(10x+18)
expand
7x-1 = 5x + 9
add 1 to both sides to separate the 7x
7x = 5x + 10
subtract 5x from both sides to separate the x
2x = 10
divide both sides by 2 to separate the x
x=5
Therefore, DE = 7(5)-1 = 34 and CE = 10(5) + 18 = 68 = AC.
Using x=5, we know that BC = 9(5) -2 = 43
Therefore, AB = AC-BC = 68-43 = 25
Answer: Option B.
Step-by-step explanation:
We know that her living room has the shape of a rectangle and its dimensions on the floor plan are:
by
We can convert from mixed numbers to decimal numbers:
We know the scale drawing of the floor plan of Trinity's house is , then, we need to multiply the dimensions of her living room on the floor plan by in order to get the dimensions of her actual living room:
Therefore, the dimensions of her actual living room are:
by
B) 231
To get the answer, you first need to figure out how many men are in the book club:
- Multiply the total number of members (315) by the fraction of members that are men (4/15)
- (4/15) * 315
- Multiply 4 by 315, and then divide by 15.
- This will give you the number of men (84)
Then you need to figure out how many women there are:
- Subtract the number of men (84) from the total number of members (315)
- 315 total members - 84 male members = 231 female members
(x^3)-10

Answer:
- Tadeo: 12 hours
- Dylan: 2 hours
Step-by-step explanation:
We can let d represent the number of hours that Dylan volunteered. Then Tadeo volunteered for 6d hours, and their total hours were ...
d +6d = 14
7d = 14 . . . . . . collect terms
d = 2 . . . . . . . divide by the coefficient of d
6d = 6(2) = 12
Tadeo volunteered 12 hours; Dylan volunteered 2 hours.
