Answer:

see explanation

Step-by-step explanation:

(1)

She had $11 left from $59,

she therefore spent $59 - $11 = $48

divide $48 by 6 to find cost of one book, that is

cost of book = $48 ÷ 6 = $8

(2)

consecutive numbers have 1 between them

let n, n + 1 and n + 2 be the three numbers. then

n + n + 1 + n + 2 = 102 ( sum of 3 numbers )

3n + 3 = 102 ( subtract 3 from both sides )

3n = 99 ( divide both sides by 3 )

n = 33

The 3 numbers are 33, 34 and 35

33 is the smallest of the three

Find the surface area of this triangular prism. Be sure to include the correct unit in your answer.
Vladimir [108]

Answer:

270 yds squared    

Step-by-step explanation:

You need to area of each of the shapes that make up the triangular prism. So, the side triangles, the back rectangle, the bottom rectangle and the top rectangle.

Side triangle (1x): base*height/2

12*5/2

60/2

30 yds, 60 yds for both sides.

Back rectangle: length*width

5*7

35 yds

Bottom Rectangle: length*width

7*12

84 yds

Top rectangle: length*width

7*13

91 yds.

To get the final answer, you add the surface areas together to get the final amount of yards: 30+30+35+84+91= 270 yds squared. Hope this helps.

a man is 18 years older than his son. 3 years ago he was 4 times as old as his son how old is the man now​
Andru [333]

Answer:

The man is 27 years old.

Step-by-step explanation:

You can create a system of equations.
Let x = the age of the man
Let y = the age of his son
You can create the following equations based on what was given in the problem:
1. x = y + 18
2. (x - 3) = 4(y - 3)
You can simplify the second equation:
x - 3 = 4y - 12
x = 4y - 9
Then, solve the system of equations:
x = y + 18
-
x = 4y - 9
____________
0 = -3x + 27
The son's age is 9, therefore the father is 27 years old.
