Answer:
answer is -3
Step-by-step explanation:
we know -,+ is -. so minus, plus is minus(here minus and plus are the signs given. opposite signs give minus wheras same signs give plus)
so, first we should subtract 7 minus 4 is 3,.
then we should insert the minus because the greater number has the minus sign. ( you should always insert a sign of a greater number after substituting)
Answer: 4 x − 7 = 2 4x-7=2 4x−7=2. Add 7 to both sides. Simplify 2 + 7 2+7 2+7 to 9. Divide both sides by 4.

None. She ate the pound she bought.
9/20 miles a minute or .45 miles a minute
Let the length be l, width w and height h, then
Volume = length x width x height
l = 10cm, w + h = 18cm
V(h) = 10(18 - h)h = 180h - h^2
V(h) = 180h - h^2
