I’m not sure how to solve the first one but the second one (c) is 24. You have to see the pattern between 15 and 45 and then do that to the denominators. The pattern is multiplying by 3 (15x3 =45) so multiply 8 by 3 and you get 24. Hope this helps and if not, please message me for further help.

For the first one, cross multiply 15 and c which is 15c and cross multiply 8 and 45 which is 360, so u get 15c = 360 and divide 15 c by 15 and 360 by 15 also then the answer would be c = 24

For the second one it’s basically the same thing, cross multiply x and 12 which is 12x and 8 and 3 which is 24, then you get 12x = 24. Divide both sides by 12 and the answer would be x = 2

If there are 420 students surveyed, which equation can be used to find the number of students s who prefer rap? Pop: 5/8 Jazz: 1

Aleksandr [31]

Answer:

B. $s=\dfrac{1}{4}\times420$

Step-by-step explanation:

Total number of students surveyed = 420

Of which only $\dfrac{1}{4}$ prefer rap.

So, the number of people who like rap is the product of the fraction of people who prefer rap and the total number of students.

$\text{Number of students who prefer rap}=s=\dfrac{1}{4}\times420\\\Rightarrow s=105$

The number of students that prefer rap is 105

So the equation is $s=\dfrac{1}{4}\times420$ .

Distance traveled varies jointly as rate and time. If Fred travels 135 miles in 3 hours at a rate of 45 mi/hr, find the rate at

Rudiy27

From the relation, d is joint proportionaly with r and t.
Thus,d = krt.

Using the first set of given, we could calculate for k.135 = k(45)(3)k = 1

Using the computed value of k.d = krtr = d/ktr = (189)/(1)(3.5) = 54 mph.
