Answer:
0.56
Step-by-step explanation:
Since 1/10 is 0.1 as a decimal you will then change it to 5.6 x 0.1 which would equal 0.56
Hope this helps :)
I would use the process of elimination. Divide 13 from both sides
2x+7y=-57 y=-7 then plug in y to an equation
-6x-8y=80 2x+7(-7)=-57 multiple
multiple the first equation by 3 2x-49=-57 add 49 to both sides
6x+21y=-171 2x=-8 divide two from both sides
-6x-8y=80 x=-4
combine like terms So your things would be x=-4 and y=-7
13y=-91 And itd make the solution (-4,-7).
Answer:
2x+2y=6
Step-by-step explanation:
-4x + -2y = -18
2x + 3y = 24
2x + 2y = 6
Answer:
168.24784 m²
Step-by-step explanation:
Area of the square:
28 x 28=784 sq. m.
Area of the circle:
π(r²)=π(14)²=196π
=615.75216
Area not covered by the sprinkler:
784-615.75216=168.24784 m²
