Question

if x = 1/10 and y = -3/8 ,v
then evaluate x + y,x - y, xxy and x÷y​

Answer 1

Answer:

Step-by-step explanation:

x+y= 1/10+ -3/8

= lcm= 40, so 1/10= 4/40 and -3/8= -15/40

4+-15/40= -11/40

Answer 2

Step-by-step explanation:

X=1/10 ; y = -3/8

=> (x + y)(x - y)( xxy )( x ÷ y)

=> {1/10 + (-3/8)} {1/10 - (-3/8)} { 1/10 × 1/10 × (-3/8) { 1/10 ÷ ( -3/8)}

=> {1/10-3/8} {1/10 + 3/8 } {1/100 × (-3/8)} { 0.1 ÷( -0.375)}

=> {0.1-0.375} {0.1 +0.375} {0.01× -0.375} { -0.26}

=> {0.275} {0.475} {-0.00375} { -0.26}

=> 0.130625×0.000975

=> 0.0001
