17.5 x 3 = 52.5
4 x 4 = 16
16 + 52.5 = 68.5
So the answer is 68.5cm
Mass of one half dollars = 11.34g
therefore mass of six half dollars = 6*11.34g
=68.04g
Ans : mass of 6 half dollars = 68.04g
It is simple
Step 1) substitute x = 5 into the equation
3x +4
3(5) + 4 gives you 3 times 5 + 4
The answer is 15 + 4 which is 19
Now substitute a and b into the equation 3(a) + 4(b) when the a = 6 and b = 5
Hereby 3(6) + 4(5)
3 * 6 = 18 and 4* 5 = 20
18 + 20 = 38
The answer is 38
Now finally
Substitute a and b Into the equation
3(3) + 4(6)
9+ 24 = 33
1 pound of rice costs $3.45
1.2 pounds of rice costs x
Set up the proportion
1 / 1.2 = 3.45 / x Cross Multiply
x = 1.2 * 3.45 Combine
x = $4.14 Answer
