750 divided by 600 x 100 = 125%
Answer:
30.00
Step-by-step explanation:
24=80%
12=40%
6=20%
80%+20%=100%
24+6=30
Answer:
x = 1 ; y = -5
Step-by-step explanation:
2x + 5y = -23 --------------(i)
5x + 13y = -60 ----------(ii)
(i)*5 10x + 25y = - 115
(ii)*(-2) <u>-10x - 26y = 120 </u> {add the two equations}
-1y = 5 {Now x is eliminated}
y = 5/-1
y = -5
y = -5 in equation (i)
2x + 5*(-5) = -23
2x - 25 = -23
2x = -23 +25
2x = 2
x = 2/2
x = 1
Answer:
10
Step-by-step explanation:
2/6 is 1/3 i third of 30 is 10
Answer:
132°
Step-by-step explanation:
We use the circle theorem which states that :
Opposite angles in a cyclic quadrilateral add up to 180 .
Now we know that angles ADC and ABC add up to 180. So :
We make an equation and solve for x :
x+(3x-12) = 180
4x-12 = 180
4x = 192
x = 48
Now we substitute the value of x into Angle B :
3(48) -12 =
144 - 12 = 132
Angle B = 132 °
Hope this helped and have a good day
