If you can't figure out how to do it, you can always use your answer choices, so for example, use choice a (21 degrees). Plug in 21 for x for both equations. So for the first equation that would be 7(21)-1= 146 and second equation 3(2)-9= 54. Then you would add the results, 146+54=200. In that case, choice 21 is wrong because both of these angles should equal to 180 since it is a supplementary angle. I hope that helped.
Answer:
P = 4w + 8
Step-by-step explanation:
<em>Jose is creating a map in the shape of a rectangle whose length is 4 inches longer than its width. Let w stand for the width of the map in inches. Write an equation gives the perimeter of the map in terms of w?</em>
Perimeter of the rectangle = 2(L +w)
L is the length of the rectangle
w is the width
If the length is 4 inches longer than its width, then;
l = w + 4
Substitute into the expression;
P = 2 (L+w)
P = 2(w+4+w)
P = 2 (2w+4)
P = 4w + 8
Hence the perimeter of the map in terms of w is P = 4w + 8
Answer:
57.75 yards yard will she makes 14 panels.
Step-by-step explanation:
Proportion states that the two ratios or fractions are equal.
As per the statement: Katrina uses 4.125 yards of fabric for each curtain panel she makes.
To find the how many yard will she makes 14 panels.
By proportion definition,
By cross multiply we have;
Simplify:
x = 57.75 yards.
therefore, 57.75 yards yard will she makes 14 panels.
2 times 3w= 6w
2 times 5y= 10y
so the answer is 6w-5y
