Answer:
<h3>
x = 4, RM = 7</h3>
Step-by-step explanation:
Given RM = x+3 and MS = 2x-1, if M is on between R and S, then RM = MS
x+3 = 2x-1
collect like terms;
x - 2x = -1-3
-x = -4
Divide both sides by -1
-x/-1 = -4/-1
x = 4
Since RM = x+3, substitute x = 4 into the expression to get the lrngth of Rm.
RM = 4+3
RM = 7
Hence x = 4, RM = 7
Answer:
176 seconds
Step-by-step explanation:
By using regression line calculator,
Equation of the line of best fit will be,
T = -12.55x + 276.52
Here , T = time taken to cover one lap
x = Age
If the age of Marsha's son is 8 years then expected time taken by her son to cover one lap will be,
T = -12.55(8) + 276.52
T = -100.4 + 276.52
T = 176.12 seconds
Therefore, approximate time taken by Marta's son will be 176 seconds.
Answer:
b=-a
Step-by-step explanation:
if the distance from origin 0 of b is the same as the distance of a from b but in opposite directions, this makes b differ from a by polarity but with similar values.
Answer:
w(w-5)
Step-by-step explanation:
Given Width of rectangle = w
Length of rectangle is 5 less than width of rectangle = w - 5
Area of Rectangle = Length x Width = w * w-5 = w(w-5)
Let, the width = w
We know, A = 2(lw + wh +hl )
250 = 2(10w + 5w + 50)
250 = 2(15w + 50)
250 = 30w + 100
30w = 250 - 100
w = 150/30
w = 5
In short, Your Answer would be Option C) 5 cm
Hope this helps!
