what is the average cost of 7 articles if 3 of them cost 30k each and the rest cost 12.5k each
TOTAL NUMBER OF ARTICLE= 7
ARTICLES FOR 30K = 3
ARTICLES FOR 12.5K = 7-3= 4
Average cost of 7 articles
The width is 8.2
Perimeter = 2W + 2L (there are four sides of a rectangle, two longer sides, two shorter, W and L)
<span>65.6 = 2W + 2L
</span><span>L = 3W so substitute 3W in for L </span>
<span>65.6 = 2W +2 (3W) </span>
<span>65.6 = 8W </span>
<span>W = 8.2 cm </span>
<span>L = 3(8.2) </span>
<span>L = 24.6cm </span>
Answer:
3 teaspoons
Step-by-step explanation:
Since we need 1 teaspoon for 2 cups, I would only assume we would keep adding a teaspoon for every 2 additional cups of chocolate chips.
2 + 2 + 2 = 6
We would need an additional teaspoon of salt for each of the sets of two.
Okay, so let's start with the labeling first:
(-4 = x1, 3 = y1) and (5 = x2, -6 = y2)
So now it's time to use the formula:
x Midpoint = (x1 + x2) / 2
y Midpoint = (y1 + y2) / 2
So then that would be:
x Midpoint = (-4 - 5) = (4 + 5) / 2 = 4.5
y Midpoint = (3 - -6) = (3 + 6) / 2 = 4.5
So therefore our answer for the midpoint would be:
(4.5, 4.5) which is D
Answer:
X = 5
Step-by-step explanation:
28 = 7x + 3 - 2x
28 = 5x + 3
28 - 3 = 5x + 3 - 3
25 = 5x
25/5 = 5x/5
X = 5
