Answer:
4
Step-by-step explanation:
Hurley drank between 4 and 5 liters of water for 8 different days and drank between 1 or 2 liters of water on 4 different days. To find the answer we have to use the following equation.
# of days Hurley drank (4-5 L) - # of days Hurley drank (1-2 L) = # of more days
8 - 4 = 4
Answer:perpendicular
Step-by-step explanation:
Answer:
3-8=-5
-5=-5
true
Step-by-step explanation:
Given: Given that a citizen have 97 silver coins.
To find : Here we need to find that how many bronze coins would it take to equal this amount.
Solution: We know, 1 silver coin=10 bronze coin
So, 97 silver coin=10×97 bronze coin
=970 bronze coin
Therefore, 970 bronze coins would it take to equal this amount.
<span>6x – 7y = 16
2x + 7y = 24
This system is easily solvable by the elimination method as the y-terms are opposites of each other. You may add the two equations together and they will cancel out.
</span> 6x – 7y = 16
2x + 7y = 24
+___________
8x – 0 = 40
8x = 40
x = 5
Substitute 5 for x into either of the above equation and solve algebraically for y.
2x + 7y = 24
2(5) + 7y = 24
10 + 7y = 24
7y = 14
y = 2
Check work by plugging both x- and y-values into each original equation.
6x – 7y = 16 => 6(5) – 7(2) = 16 => 30 – 14 = 16
2x + 7y = 24 => 2(5) + 7(2) = 24 => 10 + 14 = 24
Answer:
x = 5; y = 2
(5, 2)
