Answer:
Irrational
Step-by-step explanation:
Answer:
x = 4 , y = 1
Step-by-step explanation:
3x + 2y = 14 → (1)
x + y = 5 → (2)
Multiplying (2) by - 2 and adding to (1) will eliminate the y- term
- 2x - 2y = - 10 → (3)
Add (1) and (3) term by term to eliminate y
x = 4
Substitute x = 4 into (2) and evaluate for y
4 + y = 5 ( subtract 4 from both sides )
y = 1
Answer:
40 square yards
Step-by-step explanation:
The backyard is rectangular and it's dimensions are 7 yards long and 8 yards wide.
The area of a rectangle is given as:
A = L * W
where L = length
W = width
Therefore, the area of the backyard is:
A = 7 * 8 = 56 square yards
Elliana wants to plant sunflowers on 16 square yards of the backyard and the rest of the backyard will be used for a pool.
The area left for the pool will therefore be:
56 - 16 = 40 square yards
40 square yards will be left for the pool.
