Answer:
A.) -3
Step-by-step explanation:
-3 is less than -2 therefore, it fits the answer.
Easiest method solving 2 unknowns is Substitution.
So there will normally be 2(ormore)equations given.
Say
X+Y= a
bX=cY + d
a b c d are numbers they give
So first we rearrange the first equation
X = a - Y
No we substitute this into the 2nd equation so that we can get Y
since we know X = a-Y,
b(a-Y) = cY + d
we rearrange and we can find Y for this, it is just Y and numbers
hence finding Y, we sub the value for Y into X = a-Y and we get X also .
Answer:
16
Step-by-step explanation:
because it is
.5
Step-by-step explanation:
graph goes up by .5 between hour 2 and 3
The answer is 74.9218%
First set up the the equation 460.05/614.04
That gives you .749218
Move the decimal back twice because of the equation 74.9218
The answer is 74.9218%
Hope this helps!
