From the problem statement, we can come up with the following equations:


Plugging in
for each equation, we can get the answer:







From this, we can see that the value is equal for both stores.
(3/4) /(4/5) = x/1
cross multiply
4/5x = 3/4
x = 3/4 * 5/4
x = 15/16 tons of pebbles are needed to cover the entire garden
Answer:
D
Step-by-step explanation:
You are starting at 4 and going back 6 to -2.
Expand
Simplify 0.9x + 1.26 - 2.3 + 0.1 * x to x - 1.04
add 1.04 to both sides
simplify 1.6 + 1.04 to 2.64
Answer: x = 2.64
