Answer:
4=x
Step-by-step explanation:
y=-x+4
y=2x-8
-x+4=2x-8
+x +x
4=3x-8
+8 +8
12=3x
/3 /3
4=x
Answer:
Step-by-step explanation:
Plug in the numbers & solve for 5x, eventually eliminating the 5 to solve for x, which the variable should be on the left side, always.
Answer:
$60
Step-by-step explanation:
To find how much Zoe paid before the sales tax and tip, we first need to consider the amount she paid in sales tax and tips.
Sales tax + Tips = $18.60
Let x = original price
Sales tax = 11% * original price
Sales tax = 0.11 * x
x= 0.11x
Tips = 20% * original price
Tips = 0.20 * x
x = 0.2x
Now that we have a value for both the sales tax and tips, we can then proceed to find the original price by:
0.11x + 0.2x = 18.60
0.31x = 18.60
Now we need to divide both sides by 0.31 to find x.
x = 60
Zoe's dinner before the sales tax and tips was $60.
Total number of oz of honey = 12 oz.
Cost of 12 oz of honey = $5.40.
Cost per oz of honey = 5.40 divided 12 = $0.45 per oz.
Therefore,
a) Cost per ounce of honey = $0.45.
b) Number of ounces we can buy for one dollar = 12 divided by 5.40 = 2.22 oz approximatly.
c)
h = 2.22c, wherr h is the number of ounces of honey for c dollars.
c=0.45h, where c is the total cost of h number of ounces of honey.
d) Let us take c=0.45h equation for graph the situation.
x-axis would be for h number of ounces of honey and y-axis is the total cost c of h ounces of honey.
Let us find some values of h and c for the graph.
For equation: c=0.45h for h=1,we get c=$0.45.
If we plug h=2, we get c= 0.45*2 = $0.90.
If we plug h=3, we get c= 0.45*3 = $1.35.
Therefore, we would plot (1,0.45), (2,0.90) and (3,1.35) on the graph and draw a straight line.
