Answer: Each book costs $11

Explanation: If Josh paid for 3, 20 bills he would be paying $60, and if he got $16 in exchange you could subtract that from the amount he gave (60-16 = 44) then you would get how much all the books costs TOGETHER. But what you need to find is how much each book costs, you know they all cost the same and how much books he bought (4) so you just divide 44 by 4 which would get you 11.

(Hope this helps!)

Vlada [557]

Answer:

5x + 10y = 90

Step-by-step explanation:

X is the number of times she takes the 5 mile, so the total distance would be 5x. Y is the number of times she takes the 10 mile, so the total distance would be 10y. And together they equal 90 miles, so 5x + 10y =90. Hope this helps.

Answer:

t = 17.3

Step-by-step explanation:

The following data were obtained from the question:

Angle T = 87°

Opposite T = t =?

Opposite V = v = 14

Opposite U = u = 11

The value of t can be obtained by using cosine rule formula as shown below:

t² = v² + u² – 2vu CosT

t² = 14² + 11² – 2 × 14 × 11 × Cos87°

t² = 196 + 121 – 308 × Cos87°

t² = 317 – 16.119

t² = 300.881

Take the square root of both side

t = √300.881

t = 17.3

Therefore, the value of t is 17.3
