Answer:
<2 = 129°
Step-by-step explanation:
if I || m then 5x+12 =m<2 and m<2 + 2x + 14 = 180°
2x + 14 + 5x + 12 = 7x + 26 =180°
7x = 154 ➡x = 21°
m <2 = 5×21 + 14
A) 1/5 + 5/9
find common denominator:
9*5 = 45
pillow case: 1/5 = 9/45
table cloth: 5/9 = 25/45
9/45 + 25/45 = 34/45 was used
B. using 45 as the denominator the full piece of cloth would be 45/45
fraction left over = 45/45 - 34/45 = 11/45 left
C. from A the pillow case uses 9/45, they have 11/45 left, because 9 is less than 11, they have enough to make a pillow case
I suppose we have to find the lengh of the sides.
Area = lenght × width
288 = (3x) × (2x+10)
288 = 3x (2x+10)
288 = 6x + 30x
288 = 36x
288/36 = x
8 = x
therefore the sides are
3x = 3×8 = 24 inches
2x+10 = 2×8 + 10 = 16 +10 = 26 inches
We have the following:
The formula to calculate the cost is as follows:
In this case, p is equal a 1700, replacing:
Therefore, the cost of 1700 magnets is $1200
