Answer:
5 and 2/5 liters or 5.4 liters
Step-by-step explanation:
9/10 times 6
9 times 6 is 54. 54 divided by 10 is 5.4 which is the same as 5 and 2/5
Interest is 3.20 per 100
3.2 × 275/100
=3.2 × 2.75
answer A $8.80
Answer:
x 2 y -4
Step-by-step explanation:
13x = -54 -20y give it is A
-10x = 60 + 20y give it is B
A + B the sum of the left side of equation is equal to the sum of the right side of equation
13 + (-10x) = -54 -20y + 60 + 20y
3x = 60-54
3x = 6
x=2
so put the x value in A or B equation you can receive y value (B is easier)
y = -4
Answer:
a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
Step-by-step explanation:
Add 16 to both sides.
or 
or 
or 
Therefore, a = -4, b = 3 and c = 6 (OR)
a = -4, b = -3 and c = 6
Answer:
x=28°
Step-by-step explanation:
2x+3x-10+50=180
5x+40=180
5x=180-40
5x=140
x=140/5
x=28°
