There is no table to look at.
Anyways, to solve for the amount they will spend you will have to do some conversions to switch yards and feet to inches. Additonally, there is also a rate missing which is the cost per inch.
So here is what you’ll have to do…
1. Solve for the slope of the equation
2. See if this linear equation has a y-intercept. It can be done by looking at the table to see where x=0 or by solving using y=mx+b where you substitite the slope for “m” and any coordinate that lies on the graph for “y” and “x” to then solve for “b” which is the y-int.
3. Then write out your equation.
4. Make the conversions
5. Solve for the cost by subtituting the units of measurement into the “x”.
Answer:
Perimeter = 9700 cm
Step-by-step explanation:
Dimensions of sides are;
12, 2x, 12, 5, 5, circumference of semi circle
Now, the semi circle has a radius of 7. Thus, the diameter = 7 × 2 = 14
We see that x is the diameter. Thus, x = 14
Thus; base of trapezium that is 2x = 2 × 14 = 28
Also, circumference of semi circle = 2πr = 2π × 7 = 44
Thus;
Perimeter of shape = 12 + 2(14) + 12 + 5 + 5 + 44
Perimeter = 97 m
Converting to cm, we multiply by 100 to get;
Perimeter = 97 × 100 cm
Perimeter = 9700 cm
-7(5x-8)
=-35x + 56
which is basically 56-35x if u swap it around
