3/35 = 0.0857 = 8.57% <== percent of the tip
35 + 3 = 38 <== total cost
The slope is 3/5. You can get this answer by subtracting x1 from x2, y1 from y2 and dividing the new x by the new y.
Answer:
a^2+4a-5
Step-by-step explanation:
This is the expanded form
Oranges=r
apples=a
12<em>r</em>+7<em>a</em>=5.36
-12<em>r </em> -12<em>r</em>
What you do on one side you do on both sides
12 on the left cancels out
7<em>a</em>=5.36-12<em>r</em>
/7 /7 /7
Divide 7
7 on the left cancels out
5.36/7=0.76....
left with
<em>a</em>=0.76-12<em>r</em>/7
so the apples cost $0.76 each
to get the cost of the oranges (<em>r</em>) you do the same as you did to get the cost of the apples.
Also on the other equation for 8 oranges and 5 apples you might get different answers but you will see that they are close/similar to the same answers as you will get for the last equations.
Answer:
c = 27
Step-by-step explanation:
given 
= 
( cross- multiply )
4c = 3 × 36 = 108 ( divide both sides by 4 )
c = 27
