a.
step-by-step explanation:
step 1 distribute 2 to every term in the parentheses
step 2 add 10 on both sides of the equal sign
answer:
it will cost 480 dollars to refurbish the larger wood floor
step-by-step explanation:
as it's a ratio of 4 that costs 384 dollars, divide the price by the ratio
384 / 4 = 96 dollars
96 dollars per unit of the ratio
now to get the price to refurbish the larger wood floor, times the price by the units
96 * 5 = 480
One rose bush = $3
One bunch of ornamental grass = $4
Step-by-step explanation:
We can set up a system of equations to solve for this. Let cost of 1 rose bush be r and cost of 1 ornamental grass be g. Thus we can form 2 equations:
We can multiply the first equation by -2 so that we can eliminate g. Thus, we have:
Thus, 1 rose bush is $3. Now plugging in r = 3 into the first original equation, we can solve for g:
Thus, 1 bunch of ornamental grass is $4.
