<span>Let x = the width
:
It says,"The length of a rectangle is 4 less than 3 times the width." write that as:
L = 3x - 4
:
If the perimeter is 40, find the dimensions of the rectangle.
:
We know: 2L + 2W = 40
:
Substitute (3x-4) for L and x for W
2(3x-4) + 2x = 40
:
6x - 8 + 2x = 40; Multiplied what's inside the brackets
:
6x + 2x = 40 + 8; do some basic algebra to find x; (added 8 to both sides)
:
8x = 48
:
x = 48/8
:
x = 6 which is the width
:
It said that L = 3x - 4, therefore:
L = 3(6) - 4
L = 18 - 4
L = 14; is the length
:
Check our solutions in the perimeter:
2(14) + 2(6) =
28 + 12 = 40</span>
Answer:
1/4
Step-by-step explanation:
1/2 is also equal to 2/4 since 2 is half of 4 so 3/4 minus 2/4 will get you 1/4

Answer:
A rotation and a translation
or
rotation
Step-by-step explanation:
Again, we have to rotate to make the shape fit in, right?
But it wouldn't fit... Or will it? If you can take 2 guesses, you can try the rotation and a translation or the rotation.
Sorry, I'm also getting confused at some point :(!
Answer:neither
Step-by-step explanation:
There is no ratio to multiply by or number to add
Answer:
$30
Step-by-step explanation:
-One week has 7 days, so the total number of eggs laid by both chickens:
-One doze is equivalent to 12 items. There's only one full dozen unit in 21 pieces.
Hence, she makes $30 in week one.
