Answer:
I figure you could simplify it by multiplying both sides by 6, resulting in -31+23=-30+18-1+5
-8=-8
Step-by-step explanation:
X = 4y
3x - y = 70
substitute the x in the second equation with the other half of the first equation.
3(4y) - y = 70
12y - y = 70
11y = 70
y = 6.36 repeating, or 6 4/11
now use this to solve first equation
x = 4 (6 4/11)
x = 25.45 repeating
done
I) 80% x 5640 = Rs. 4512
ii) 4512 divide by 50 = Rs. 90.24
Answer:
3, 6, 9
Step-by-step explanation:
When changing a fraction to a decimal, you divide the numerator by the denominator. For EX.
1/3= 1 divided by 3
1 divided by 3 is 0.3333333333333
1/6
1 divided by 6 is 1.6666666666666
1/9
1 divided by 9 is 0.1111111111111111111111
