X/32 = 80/100
^to solve use cross products
32 x 80 = 2560
2560 ÷ 100 = 25.6
$32 + $25.60 = $57.60
Answer:
(1, 3 )
Step-by-step explanation:
To find a solution choose a value for x, substitute into the equation and solve for y.
let x = 1 , then
- 7(1) + 3y = 2 , that is
- 7 + 3y = 2 ( add 7 to both sides )
3y = 9 ( divide both sides by 3 )
y = 3
One possible solution is therefore (1, 3 )
Answer:
Probability is 2/5 or 40%.
Step-by-step explanation:
4/(4+2) = 4/6 = 2/3 first black pen is chosen.
3/5 - second pen is chosen without replacement.
2/3 *3/5= 2/5 - the probability a black pen was chosen, and then another black pen without replacement.
2/5*100 % = 40 %
Answer:
28.5
Step-by-step explanation:
Take the total # of pages to be READ, 128.5, divide by the # of days, 4.5, your answer is pages to read per day. 128.5/4.5 =28.55. Check your answer by multiplying 28.55x4.5 = 128.5
Hope this helps.

Answer:
radius =
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
(x - 1)² + (y + 3)² = 73 ← is in standard form
with r² = 73 ( take the square root of both sides )
r =
