Answer:

y = 2

Step-by-step explanation:

Given

7y - (9 + 4y) = - 3 ← distribute parenthesis by - 1

7y - 9 - 4y = - 3 , that is

3y - 9 = - 3 ( add 9 to both sides )

3y = 6 ( divide both sides by 3 )

y = 2

A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part. How long is e
Pachacha [2.7K]

Answer:

The longer part is <u>45 cm</u> long and the shorter part is <u>25 cm</u> long.

Step-by-step explanation:

Given:

A 70 cm long stick is cut into two parts in such a way that the longer part is 20 cm longer than the shorter part.

Now, to find the length of each part of the stick.

Let the shorter part be x.

So, the longer part is x+20.

Total length of the stick = 70 cm.

Now, to get the length of each part we solve an equation:

(x)+(x+20)=70\\\\x+x+20=70\\\\2x+20=70\\\\Subtracting\ both\ sides\ by\ 20\ we\ get:\\\\2x=50\\\\Dividing\ both\ sides\ by\ 2\ we\ get:\\\\x=25.

<em>The length of the shorter part is 25 cm.</em>

Now, substituting the value of x:

x+20\\\\=25+20\\\\=45\ cm.

<em>The length of longer part is 45 cm.</em>

Therefore, the longer part is 45 cm long and the shorter part is 25 cm long.

The Martinez family is traveling to a play in Richmond. A round trip train ticket costs $8.00. Children under the age of 7 trave
tatuchka [14]

Answer: The Martinex family spent $ 82 for train ride and play tickets.

Step-by-step explanation:

Round trip train cost = $ 8.00

For children it cost $ 4.00.

For adult, ticket for play costs= $ 14.00

For children , ticket for play costs= $ 6.00

Mr. And Mrs. Martinez will go with their children, Ricky, Ramona, and Thomas.

2 adults and 3 children ( only one of them is under 7.)

For train we consider only 1 as child rest as adult.

Train cost =  4 x($ 8.00)+ 1 x ($ 4.00)

= $ 32+4 = $36

For play , total cost = 2 x ( $ 14.00) + 3 x ($6)

= $(28+18)

= $ 46

Total spending ( combined) =  $36+$ 46

= $82

So, the Martinex family spent $ 82 for train ride and play tickets.
