Answer:
70
Step-by-step explanation:
180 -(60+65) = 180 - 125 = 55
180 - (50 + 55) = 180 - 105 = 75
180 - (35 + 75) = 180 - 110 = 70
Answer:
(x,y)=(-1,-4)
Step-by-step explanation:
-4x + y = 0
+4x +4x
y=4x
-5x - 2y = 13
+5x +5x
-2y = 5x+13
-2(4x) = 5x+13
-8x=5x+13
-5x -5x
-13x/-13=13/-13
x=-1
Thus:
y=4x
y=4(-1)
y=-4

Answer:
do you want probability in fraction, percent, or decimal form?
Step-by-step explanation:
their is one 3 on a regular dice which has 6 numbers
this gives you the fraction 1/6
but since you are rolling the dice twice you would have 1/6 × 1/6 giving you 1/36
if in percent form this would be 2.77777778% or rounded to 3%
and decimal form as 0.0277777778 or rounded to 0.03%
