48-2x=96--------- -2x=48--------- x=-24. You multiply everything by 6 then solve.
Let
x---------> amount of money saved by Mark
x---------> amount of money saved by Neil
we know that
x=y+258-------> equation 1
x/y=(7/4)-------> equation 2
substitute equation 1 in equation 2
(y+258) /y=7/4--------> 4*(y+258)=7*y------> 4y+1032=7y
7y-4y=1032--------> 3y=1032------> y=$344
x=344+258------>x=$602
the answer is
$602
Answer:
6
Step-by-step explanation:
first you do -3+6 which is 3.
then, u do -3+5 which is 2

Answer:
22
Step-by-step explanation:
10*1=10
then as we know first we should do multiplier and division so,
2*60=120, 120/10=12
10+12=22
Answer:
4.038
Step-by-step explanation:
The simple regression model is:
, then 
.
The statistic calculated for the hypothesis test of statistical significance, for the slope, in a simple regression model is given by:
with 
the slope estimator, 
the value of slope in the null hypothesis and 
the standard error of the slope. Thus,
