Answer:
1.5 miles
Step-by-step explanation:
Step-by-step explanation:
-5x + 4y = 2
+ (9x - 4y = 6)
=> 4x = 8, x = 2.
Therefore -5(2) + 4y = 2, 4y = 12, y = 3.
The solution pair is (2,3).
In the slope intercept formula (y = mx + b)
the m = slope
the b = y intercept
hope this helps :)
you have to rearrange the equation to match the formula
so.....
-y = 6x - 6
m = 6x/-y = -6 (you can just see it as 6/-1 you dont have to count the x and y)
b = -6
Steps:
1. Change 1/11 to 2/22 by multiplying by 2
2. 9/22 + 2/22
3. 11/22
Then, to simplify it you divide by 11
4. Your answer is
1/2
First stack has 8 blocks.
Second stack has 12 blocks.
Third stack has 8 blocks.
Fourth stack has 14 blocks
8+12+8+14=42
There’s a total of 42 wooden blocks used.
