Question

if x=5 c=4 and double y=10.0 r=3.5, answer the following with explanation​

Answer 1

Answer:

x=5,double y=10,y=10/2=5,c=4,r=3.5

Explanation:

1)xy-5

=5×5-5

=25-5

=20

2)x-3y/x

=5-3×5/5

=5-15/5

=5-3

=2

3)y/c+x-r

=5/4+5-3.5

=1.25+5-3.5

=6.25-3.5

= 2.75

4)y-c*x+r

=5-4×5+3.5

=5-20+3.5

=-14+3.5

=-10.5

(or)

4)y-c*x+r

=5-4×5+3.5

=1×5+3.5

=5+3.5

=8.5

5)2(xy+xr)

=2(5×5+5×3.5)

=2(25+17.5)

=2×32.5

=65
