14 hours = $112
1 hour = 112 ÷ 14 = $8
-----------------------------------------------
Answer: It is $8/hour
-----------------------------------------------
Given that 2 large puzzle costs $16 then
2l=16
or
l=8
That means cost of 1 large puzzle = $8
Given that 3 small puzzle costs $15 then
3s=15
or
s=5
That means cost of 1 small puzzle = $5
Now we will use this information to find the correct choice.
---
First choice is <u>wrong </u>as coefficient 8 is with 8l so that gives cost of 1 large not small puzzle.
---
Second choice is <u>correct </u>as coefficient 8 is with 8l so that gives cost of 1 large puzzle.
---
Third choice is <u>correct </u>as coefficient 5 is with 5s so that gives cost of 1 small puzzle.
---
Fourth choice is <u>Wrong </u>as coefficient 5 is with 5s so that gives cost of 1 small not large puzzle.
---
Fifth choice is <u>wrong </u>as constant 128 gives total cost of not the total number of puzzles.
Answer:
EF=3.6
Step-by-step explanation:
I'm going to use Pythagorean Theorem for side EF.
4.8^2+EF^2=6^2
23.04+EF^2=36
-23.04 -23.04
EF^2=12.96
sqrt sqrt
EF=3.6
- 1.}--diagonals bisect each other
- 2...and...3}.---two pairs of opposite sides are parallel and equal
- 4.}--opposite angles are equal
- 5…}---diagonals bisect each other
- <em><u>none. I has no solutions (in all x, y and z) because in case x+y+z is 3 it can never be 4. So, it's imposible to find any (x,y,z) so that they satisfy both equations.</u></em>
- <em><u>To find the slope, convert the equation 21x - 3y + 18 = 0 to slope-intercept form (y = mx + b, where m is the slope and b is the y-intercept). To do so, first subtract 18 and 21x from both sides to get -3y = -21x - 18. Then divide both sides by -3 to get y = 7x + 6. Therefore the slope is 7.</u></em>
