Answer:
x = 5 and y = 1 or (5, 1)
Step-by-step explanation:
2x -3y=7
3x-2y=13
Multiply (1st) equation by 3 and (2nd) equation by 2
6x -9y=21
6x-4y=26
----------------subtract
-5y = - 5
y = 1
Substitute y = 1 into 2x -3y=7
2x -3(1)=7
2x - 3 = 7
2x = 10
x = 5
Answer
x = 5 and y = 1 or (5, 1)
So first we find the change
45 to 15=45-15=30
change is 30
rate of change=(change)/(original)
original=45
change=30
30/45=10/15=2/3=0.66666666=66%
rate of change is 66.66%
Answer:
the unknown number of fish is 26
Step-by-step explanation:
I figured this out by subtracting 68 - 47 = x.
x = 26
Answer:
BC = 19.78
Step-by-step explanation:
using sin(x) rule
sin(54)= 16/BC
sin(54)=0.80
∴0.80=16/BC (divied both side by 0.80)
BC=16/0.80 =19.78
