This problem can simply be expressed in an equation. Let's say that x is the amount of sales that is being looked for here. So our equation will be 0.03x = 180. So to put it simply, the amount of sales (x) has to be multiplied by 0.03 in order to get 180. So to solve for x, all we have to do now is divide 180 by 0.03. If we do that, we will be able to get a final answer of 6,000. So we can conclude that the total amount of sales received by the salesperson is 6,000.
Answer:
(3,-2)
Step-by-step explanation:
Part A:
1) <em>Isolate x in x - y = 5</em>
x = y + 5
2) <em>Substitute that x into 4x+y=10</em>
4(y + 5) + y = 10
4y + 20 + y = 10
5y = 10-20
5y = -10
y = -2
3) Use y to solve for x:
x = -2 + 5
x = 3
Part B:
<em>Verify using results from Part A</em>
3 - (-2) = 5
4(3) + (-2) = 12 - 2 = 10
Part C:
<em>Just graph the equations and see where they intersect, which is exactly (3,-2). We got that in Part A and B</em>
x + 2y = 9
x + 3y = 13
____________________________________________________________
Solve for x in the first equation. Subtract 2y from both sides.
x = 9 - 2y
____________________________________________________________
Plug x into the second equation.
(9 - 2y) + 3y = 13
Combine like terms.
9 + y = 13
Subtract 9 from both sides.
y = 4
____________________________________________________________
Plug y back into the first equation.
x + 2(4) = 9
x + 8 = 9
Subtract 8 from both sides.
x = 1
____________________________________________________________
x = 1
y = 4
7. the unit rate is 30 divide 60 by 2 and 90 by 3 to show u r work
8.the unit rate is 1.89 divide 18.90 by 10 and so on
I think it’s an regular because it looks like an rectangle
