Hi there!
To solve your answer, since we know a = 7, we can easily solve your equation.
But before we go onto that, I want to show you a tip or two about solving equations with variables next to numbers.
When you have a number, and a variable attached to it, it means to multiply.
Now, to make this equation look a little easier, lets rewrite it.
9 × 7 - 5 × 7 = ___
According to PEMDAS, we won't go straight from left-to-right when solving here. We'll skip around a little.
9 × 7 = 63.
5 × 7 = 35.
Now, since we've multiplied the two numbers, its time to subtract them.
63 - 35 = 28. Sooooo........
9 × 7 - 5 × 7 = 28
Hope this helps!
Message me if you need anything else, I'd be happy to help you out! :D
First, before multiplying to cancel the fraction, let's isolate x by subtracting both sides by 3:
b/9 < 1
To cancel out the fraction, we multiply both sides by 9:
x < 9
Answer and Step-by-step explanation:
It is 3 dollar per pound.
To figure this out, you would have to divide each number by 8. This reduces 8 pounds to 1 pound, and 24 dollars to 3 dollars.

120 square inches because a circle is 360 degrees so there will be 6 60 degree sections in it and each 60 degree section needs 20 square inches to cover it so 6 x 20= 120
F(0) = -1/5
f(4) = 7/17
f(4) - f(0)
average rate of change = --------------
4 - 0
(7/17) - (-1/5)
average rate of change = ---------------------
4
52/85
average rate of change = ---------
4
average rate of change = 52/85 *4
average rate of change = 208/85
