In 5 years kate will be twice as old as joey. right now kate is 11 years older then joey. right now how old is joey?

natima [27]

K = Kate's age nowJ = Joey's age nowK+5 = Kate's age in 5 yearsJ+5 = Joey's age in 5 years From the first sentenceK+5 = 2(J+5) From the second sentenceK=J+11 So our system of equations isK+5 = 2(J+5)K=J+11 The first equation is equivalent toK+5 = 2J+10or by rearranging termsK-2J=5 The second equation is equivalent toK-J=11 This gives us K-2J=5K-J=11 Using the elimination method, we need to multiply one of the equations by a factor such that we can eliminate one of the variables. This means we want one of the variables to have coefficients which are the same magnitude but opposite signs. We can do this by multiplying the 1st equation by -1. This give us -K+2J=-5 K - J = 11 Now add these two equations together, term by term. This gives usJ=6 So Joey is 6 years old now.

A library ordered 956 new books. They ordered 12 times as many mystery books as romance. They ordered 52 more science fiction bo

Nataly_w [17]

Answer:

Romance books ordered = 65

Mystery books ordered = 775

Science Fiction book Ordered ≈ 116

Step-by-step explanation:

Total number of books ordered in the library = 956

Let us assume the number of romance books ordered = m

⇒Number of mystery books ordered = 12 x (Number of romance books)

= 12 x(m) = 12 m

Also,number of science books ordered = 52 +(Number of romance books)

= 52 + m

Now, according to the question:

Number of { romance books + mystery books + science books} = 956

or, m + ( 12 m ) + (52 + m) = 956

or, 14 m = 956 - 52

or, 14 m = 904

⇒ m = 904/ 14 = 64.6

So, the number of romance books ordered = 64.6 ≈ 65

Number of mystery books ordered = 12 m = 12 x 64.5 = 775

Number of science fiction book ordered = = 52 + m = 116.6 ≈ 116
