Answer:
22
Step-by-step explanation:
since q is given as r + 10 we can add 10 to 12 in the missing place and find the value
2 x 10^7= 20,000,000
4 x 10^6= 4,000,000
20,000,000 - 4,000,000= 16,000,000.
In SI Notation its 16 x 10^6...

Download math-way that’s a good app it will help you with all your math/algebra problems I’m doing a exam so I don’t have time to put all the equations to find the answers sorry :(
If the salesperson earns 3%, then that's 0.03*1400, which equals 42 dollars of commission
<h3><u>The correct answer is: B.</u></h3>
We could use a graphing calculator to solve this easily, but let's just solve it by looking at the equation.
We'll need to turn this standard form equation into a slope-intercept form equation to be able to easily solve it.
Isolate y.
2x - 3y = 7
<em><u>Add 3y to both sides.</u></em>
2x = 3y + 7
<em><u>Subtract 7 from both sides.</u></em>
3y = 2x - 7
<em><u>Divide both sides by 3.</u></em>
y = 2/3x -7/3
Now, we can plug each x value in the answer choices into x to find the corresponding y value.
y = 2/3(7) - 7/3 = 2.34
As this y value does not match, A is not the answer.
y = 2/3(-4) - 7/3 = -5
This y value does match, so B is the correct answer.
y = 2/3(-9) - 7/3 = -8.34
This y value doesn't match either, so C is not the answer.
y = 2/3(9) - 7/3 = 3.67
This y value doesn't match either, so D is not the answer.
