Answer:
18b + 6
Step-by-step explanation:
Perform the indicated multiplication first:
(2+b)•5+4(3b-1) => 10 + 5b + 12b - 4 => 18b + 6
To calculate the distance between these two points, we use the Pythagorean theorem since the two points can form a right triangle when plotted where the hypotenuse would be the distance between these two. We do as follows:
d = √[(x2-x1)^2 + (y2-y1)^2]
d = √[(3-1)^2 + (9-4)^2]
d = √29 = 5.39 units
The correct answer is A.
Answer:
i would have to say the square root of 26 since its 5.099
Step-by-step explanation:
12w - 27 = -34 + 14
w = 7/12
A -2w+21=-8w+36
w=17/8
B -5/6 w + 2 = -34+14w
w=216/89
C -47-10w=-9w-40-3w
w= 7/2
D 8/7w=13/14w+2
w=28/5
<h2>
2 green beans</h2>
Step-by-step explanation:
Let the number of beans Tom ate on thursday be 
.
Let 
be the difference between the number of beans he eats on a day and its previous day.
It is given that he eats 7 more beans every day than the previous day.
So,
So the number of beans he eats is 
This is a arithmetic progression because the difference between any two terms in the series is constant.
There are seven days between thursday and following wednesday both inclusive.
Let 
be the number of terms in arithmetic progression.
Sum of first n terms in arithmetic progression is 
Since it is given that he ate 161 in total.
substituting 
and ,
So,he ate 2 beans on thursday.
