Answer: $13
Step-by-step explanation:
To determine the solution arithmetically in two steps, first divide 68.25 by 3 and then subtract 9.75 from the result. To determine the solution algebraically, set up and solve the equation 3(x+9.75)=68.25. Each friend paid $13 for dinner.
We are looking for the approximate solution of

, that is, we are looking for the solution of the equation f(x)=g(x).
The solution of this equation are represented by the intersecting points (x, y) of the graphs of these functions, because the intersecting points (x, y) are such that
y=f(x), but also y=g(x).
From the graph, we can see that there are two solutions, one is at approximately x=2, and the other is approximately -1.4.
Answer: -1.4, 2.
Answer:
8.3 cm
Step-by-step explanation:
<h2>so area of a square= side×side</h2><h2>since all sides are equal in a square</h2><h2>so= s×s=70cm²</h2><h2>√s²=√70</h2><h2>s=8.3 cm</h2>
So first let’s combine like terms and add 4/9x and 1/5x together to get 29/45x =58. Next, multiply 58 by 45/29 to isolate x, so x=90
