Bobby's dad is 41 and is 6 more than 5 times Bobby's age. Bobby's little sister Emma is one less than half his age. How old are
34kurt
Bobby is 7 and his sister is 3.

Explanation : his dads age : 41
since his dads age is six more than, you would subtract 6 from 41 to get 35.
and since 35 is 5 times bobby’s age you would divide 35 by 5 to get 7
So bobby is 7.

bobby’s sister :
bobby’s age : 7
bobby’s little sisters age is one less than half of his age you subtract 1 from 7 and you would get 6
Now that it’s one less you have to find half so divide 6 by 2 and you’ll get 3
So bobby’s sister is 3.



bobby’s age : 41 - 6 = 35
35 (divided by) 5 = 7
bobby’s sister : 7 - 1 = 6
6 (divided by) 2 = 3

Step-by-step explanation:

I just answered that. so, here again :

all we need to do is find the surface area, deduct windows and door areas.

that gives us the m² to be covered, which we have to multiply by $12.50 to get the total price.

the house surface area is like for a box, but we don't care about the top and the bottom. only about the walls.

the "box" is 18 m × 14 m × 4 m.

so, the front and the back walls are each

18m × 4 m = 72 m²

both front and back : 2×72 = 144 m²

each side wall is

14m × 4m = 56 m²

both sides : 2×56 = 112 m²

now for the deductions.

each window is

1.5 × 2 = 3 m²

both windows : 2×3 = 6 m²

the door is

1 × 2.5 = 2.5 m²

so, the total area to "side" is

144 + 112 - 6 - 2.5 = 247.5 m²

to side 247.5 m² it costs

247.5 × 12.5 = $3,093.75

Could somebody please help me find the answers for 'x' for these pictures?
lesya692 [45]

Answer:

Pic 1: x=31

Pic 2: x=20

Step-by-step explanation:

<u>Picture 1:</u>

<u />2x+x-3=90\\3x-3=90\\3x=93\\x=31

First, add the 2x and x together for 3x

Then add 3 to both sides of the equation

Finally, divide each side by 3.

<u>Picture 2:</u>

<u />7x+x+20=180\\8x+20=180\\8x=160\\x=20<u />

First, add 7x and x together for 8x

Then, minus 20 from both sides of the equation

Finally, divide each side by 8.
