The probability of Alyssa picking a nickel and a quarter would be 11/15 (eleven over fifteen)
6/15 plus 5/15 which is 11/15
You get 15 as the denominator because you add 6+4+5=15
I hope u understand.
Answer:
y = 3x + 1.
Step-by-step explanation:
The slope is y2-y1/x2-x1
= 10/1/ 3-0
= 9/3
= 3.
Using the point-slope form for a straight line:
y-y1 = m(x-x1) (m = slope)
y - 10 = 3(x - 3)
y - 10 = 3x - 9
y = 3x - 9 + 10
y = 3x + 1 is the required equation.
c is the answer of this question because the case given is necessary
Answer:
BAC is 78°
Step-by-step explanation:
BCA = 180° - BCD ( angle in a straight line is 180°)
= 180° - 113°
= 67°
BAC = 180° - BCA - ABC (angle in a triangle is 180°)
= 180° - 67° - 35°
= 78°
Compose an equation
2/5x=3/20
Then solve
8/20x=3/20
8x=3
x=3/8
