Answer:
7 / 10 14 / 20 21 / 30
Step-by-step explanation:
7 out of 10 is its simplest form the equivalent ratio of 7 * 210 * 2 equals 14 / 27 / 10 * 3 * 3 equals 21/30 letter answer
45 = 3×3×5
54 = 2×3×3×3
Two number : 3,3
So, the GCD of 45,54 is 3×3= 9
about 9 right handed gloves were sold, and about 3 left-handed gloves were sold.
In the form of algebra substitution is the method used in simultaneous equations.
E.g y=2x+5 and y=5x-1
Solve for x and y
Since we know two examples of what y is, we can substitute one y in replacement of the other to get.
2x+5=5x-1 then we solve for x to get:
x = 2 sub this back in to get y = 2(2) +5
y = 9
