Answer:
x= y=5-
Step-by-step explanation:
x+y=5
y=5-x
x-y=a
x-(5-x)=a
2x-5=a
2x=a+5
x=
x+y=5
+y=5
y=5-
Answer:
4.432432 * 10^(13)
Step-by-step explanation:
We need to divide
(1.64 x10^(-24))
---------------------
(3.7 x10^(-38))
We can first divide (1.64/3.7)
0.4432432 * (10^(-24))
---------------------
(10^(-38))
Since the term consists of a division with the same base, we just need to subtract the exponents
0.4432432 * (10^(-24 - (-38)))
= 0.4432432 * 10^(-24 +38)
= 0.4432432 * 10^(14)
= 4.432432 * 10^(13)
Answer:
first option
Step-by-step explanation:
y = 1/4x - 5/4
this line has a slope of 1/4 and a y-intercept of -5/4
Try graphing using the x-intercept and y-intercept.
-15x - 5y = 45
Put in x = 0 to get -5y = 45, making y = -9. Point (0, -9) is on the line.
Put in y = 0 to get -15x = 45, making x = -3. Point (-3, 0) is on the line.
-2x + 6y = 6
Put in x = 0 to get 6y = 6, making y = 1. Point (0, 1) is on the line.
Put in y = 0 to get -2x = 6, making x = -3. Point (-3, 0) is on the line.
(We've actually stumbled on the solution since (-3, 0) is on both lines!)
Graph the two lines using the points found above.
The solution is x = -3, y = 0.
Answer: x = 6
NS = 8.5
Step-by-step explanation:
JK = KL= KP + LP
26 = 13 + 2x + 1
2x = 12
x = 6
NS = PS
PS = 8.5
NS = 8.5
