BK / QZ = 45/27 ; substitute whit what you see in the picture
(4x+1) / (2x+7) = 45/27 ; cross multiply
27( 4x+1) = 45( 2x+7) ; distribute
108x + 27 = 90 x + 315; subtract 90x and 27 from both sides
108x -90x = 315 -27; combine like terms
18x = 288; divide both sides by 18
x=16
BK = 4* 16 +1 = 65

[tex]\frac{28}{54} = \frac{2x+8}{5x-4}[/tex]
Answers
Step-by-step explanation:
step 1. what is the question? solve for x? okay.
step 2. 28/54 = (2x+ 8)/(5x - 4)
step 3. 28(5x - 4) = 54(2x + 8) (cross multiplication)
step 4. 14(5x - 4) = 27(2x + 8) (divide both sides by 2)
step 5. 70x - 56 = 54x + 216 (distributive property)
step 6. 16x = 272 (group x's and add 56 to both sides)
step 7. x = 17 (divide both sides by 16).

y = __ √_ ????
the first blank is a fraction with two numbers on top
Answers
Answer:
Here we have two triangle rectangles, and we want to know the value of y, the shared cathetus between them.
First, we know that one of them has an angle of 60° and the adjacent cathetus to it is a.
The other has an angle of 30° and the adjacent cathetus is b.
In both cases, the opposite cathetus is y.
Now we can recall the relationship:
Tan(a) = (opposite cathetus)/(adjacent cathetus)
Then we can write:
tan(60°) = y/a
tan(30°) = y/b
And we also know that:
a + b = 15
Then we have 3 equations:
tan(60°) = y/a
tan(30°) = y/b
a + b = 15
To solve this, we first need to isolate one variable in one of the equations, i will isolate a in the third equation:
a = 15 - b
Now we can replace it in the first equation to get:
tan(60°) = y/(15 - b)
i will rewrite this one as:
tan(60°)*(15 - b) = y
then our system is:
tan(60°)*(15 - b) = y
tan(30°) = y/b
now we can isolate b in the second equation to get:
b = y/tan(30°)
and then replace it on the other equation to get:
tan(60°)*(15 - y/tan(30°)) = y
Now we can remember that:
tan(60°) = √3
tan(30°) = (√3)/3
Replacing these in our equation we get:
√3*(15 - y/((√3)/3)) = y
we can rewrite this as:
√3*(15 - y*3/√3) = y
then:
(√3)*15 - y*3 = y
(√3)*15 = y + y*3
(√3)*15 = 4*y
(√3)*15/4 = y
then we get:
[tex]y = \frac{15}{4} *\sqrt{3}[/tex]

Answers
Answer:
D) People who used a particular Web site
Step-by-step explanation:
The experimental unit is usually defined as the physical subject which can be assigned randomly to a treatment. It is also defined as the subject for which a researcher is trying to make a conclusion or inference.
Now, in this case, the subject is the number of people that worked weekly hours using the networking website.
A bicycle manufacturing company makes a particular type of bike. Each child bike requires 4 hours to build and 4 hours to test. Each adult bike requires 6 hours to build and 4 hours to test. With the number of workers, the company is able to have up to 120 hours of building time and 100 hours of testing time for a week. If c represents child bikes and a represents adult bikes, determine which system of inequality best explains whether the company can build 10 child bikes and 12 adult bikes in the week. (2 points) Group of answer choices Yes, because the bike order meets the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 Yes, because the bike order meets the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 6a ≤ 120 and 4c + 4a ≤ 100 No, because the bike order does not meet the restrictions of 4c + 4a ≤ 120 and 6c + 4a ≤ 100

Answers
Answer:
27.
Step-by-step explanation:
9 / 1/3
= 9 * 3/1
= 9 * 3
= 27.
Exact Form: 28 /3
Decimal Form: 9. 333
First keep the denominator how it is.
To get the the numerator multiply the 9 by the denominator which is 3 so you will get 27. Then add the numerator which is 1 to 27 so you will get 28.
So the answer is 28/3 in exact form. To convert it to decimal form you just multiply 28 by 3.
