Answer:
B
Step-by-step explanation:
tan(30)=n/(5*sqrt(3))
=> n=5
X + y = 13......x = 13 - y
2x - 3y = 1
2(13 - y) - 3y = 1
26 - 2y - 3y = 1
-2y - 3y = 1 - 26
-5y = -25
y = -25/-5
y = 5
x + y = 13
x + 5 = 13
x = 13 - 5
x = 8
so, x = 8 and y = 5
Answer:
u ≤ 2
Step-by-step explanation:
Given
- 10 ≤ - 5u
Divide both sides by - 5 , reversing the symbol as a result of dividing by a negative quantity.
2 ≥ u , then
u ≤ 2
Answer:
The answer to your question is: 2 pieces of paper.
Step-by-step explanation:
Data
6 ft²
1 present = 3 1/8 ft²
Process
Get the result of adding the area needed to wrap to presents.
3 1/8 + 3 1/8 = 6 2/8 = 6 1/4 Remember to add the
whole numbers and the
fractions independently.
Each paper measures 6 ft² and we need to wrap two presents 6 1/4 ft², so we need to pieces of paper to wrap the presents.
