Answer:
x=3
y=5
Step-by-step explanation:
x+5y=28 (i)
-x-2y=-13. (ii)
add equation 2 from equation 1
x+5y=28
-x-2y=-13
3y=15
y=5
put the value of y in equation 1
x+5y=28
x+5*5=28
x+25=28
x=28-25
x=3
Answer:
86
Step-by-step explanation:
(2+2=4) 4 to the 3rd power is 64. 150 minus 64 is 86
Answer:
angle BOD = angle AOC
( cuz they are vertical opposite angles )
so angle BOD = 65°
add the 2 probabilities together:
0.297 + 0.423 = 0.72
Answer is C
Answer:
1:4
Step-by-step explanation:
Given
3: 12
To express in the form 1:n
Consider how to make 3 equal to 1, we simply divide 3 by 3 to get 1 as such, we would also divide 12 by 3
3:12
= 3/3:12/3
= 1:4
Comparing with 1:n, it is safe to say that n = 4
