Answer:
2.10
Step-by-step explanation:
# of large ice creams: 240/3 = 80
# of small ice creams: 240 - 80 = 160
Total large ice cream cost: 80*3.8 = 304
Total small ice cream cost: 640 - 304 = 336
Cost of one small ice cream: 336/160 = 2.1
Answer:
Opposite sides of parallel are just like diagonal and the other diagonal going the other way.
Step-by-step explanation:
Answer:
(2, 3 )
Step-by-step explanation:
Given the 2 equations
x - 2y = - 4 → (1)
2x + y = 7 → (2)
Multiplying (2) by 2 and adding to (1) will eliminate the y- term
4x + 2y = 14 → (3)
Add (1) and (3) term by term to eliminate y, that is
5x = 10 ( divide both sides by 5 )
x = 2
Substitute x = 2 into either of the 2 equations and evaluate for y
Substituting into (2)
2(2) + y = 7
4 + y = 7 ( subtract 4 from both sides )
y = 3
Solution is (2, 3 )
No it is not a prime number
