Five years ago:
Peter= P-5
Sam = S-5
Peter was 3 times older than Sam, which means that (P-5) = 3(S-5)
P-5 = 3S-15
So, the equation that would complete the system is C. P - 5 = 3S - 15
P-5 = 3S-15
P-3S = -15+5
P-3S = -10
So, now we use two equations: P-3S = -10 and the original one P+S=30
P-3S=-10
P+S=30 (to simplify the equation, multiply it by -1)
P-3S=-10
-P-S=-30
__________
0P-4S=-40
-4S=-40
4S=40
S=40/4
S=10
P+S=30
P+10=30
P=20
This means that Pete is 20, and Sam is 10. Hope this helps!
Answer:
kindly put the complete question because you just wrote the question without the equation
Answer:
I would prefer 2×2×2×3
Step-by-step explanation:
2×2×2×3
or
24 = 2³ x 3
Answer:

Step-by-step explanation:
Given the equation

comparing the equation with the slope-intercept form
Here,
so the slope of the line is 2/7
As we know that the slope of the perpendicular line is basically the negative reciprocal of the slope of the line, so
the slope of the perpendicular line will be: -7/2
Therefore, the point-slope form of the equation of the perpendicular line that goes through (4,-6) is:





75.40
+19.25=
94.65*-5 3/4%
or
94.65*-5.75%=-5.448125
94.65-5.45= $89.30
