Answer:
150 red bars
Step-by-step explanation:
To solve this, you can use proportions. First, set up your two ratios (4:3 is equal to 200:___). Each ration represents the number of green bars to red bars. To get from 4 to 200, you can multiply 4 by 50. You could do the same to 3. 3 times 50 is 150, so there are 150 red bars.
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4
The probe dropped 11 feet per minute, therefore, it dropped 11 feet in the first minute
Answer:
x=3
y=-1
Step-by-step explanation:
add
x+y+x-y=2+4
2x=6
x=6/2=3
3+y=2
y=2-3=-1
