Answer:
y = 3x + 10
Step-by-step explanation:
y-x=10+2x
Bring x to the other side
y = 10 + 2x + x
y = 3x + 10
Answer: 79
Step-by-step explanation:
Line up the numbers from least to greatest. 39, 42, 44, 51, 55, 62, 66, 72, 77, 81, 94, 86 Then find the Median. Look at the upper part of the data set and from there find the 3rd quartile.
That is an arithmetic sequence of the form:
a(n)=2n-1
Now the sum of an arithmetic sequence is just the average of the first and last terms times the number of terms...
We know the first term is 1, let's find the last term...
a(1000)=2(1000)-1=1999
So the sum of that sequence is:
1000(1999+1)/2
1,000,000
Answer:
21 inches Sq
Step-by-step explanation:
Area of triangle=1/2 * b * h
where Height= 7 in and Base = 3in + 3in= 6in
so 1/2*7*6=0.5*7*6=21
