3b because b^2-4= 1/b. So 2/1/b= 2b b+2b = 3b
Answer:
96 , 144
Step-by-step explanation:
Ratio = 2 : 3
2x + 3x = 240
5x = 240
x = 240/5
x = 48
2x = 2*48 = 96
3x = 3*48 = 144
Step-by-step explanation:
the answer is y=-6 when x=-3
The first step to solve this problem is to compute for the
total money of Veronica. You can do this by:
$35 (given to bill) / 20% (percentage of her money given to
Bill) = $175
Since you already know the total money of Veronica, you can
now compute how much she spent to buy books which are 50% of her remaining
money after giving Bill $35.
($175 - $35) x 50% = $70
Therefore, she spent $70 for her books.
$175 – $35 – $70 = $70
Therefore, she has $70 left.
Answer:
height: 7 in
base: 14 in
Step-by-step explanation:
Let the height of the triangle equal x. This means that the base can be represented by the expression 2x. Now we plug these values into the area formula for a triangle:
A = bh / 2
49 = x * 2x / 2
And simplify
49 = x^2
We can find the square root of both sides to get x = 7, so the height is 7 inches. Since the base is twice the height, it is 14 inches.
