Answer:
- Variable x in first equation
Step-by-step explanation:
<u>Given system</u>
Variables in this system are x and y.
Isolating a variable means rearranging the equation so that a variable of our interest is on its own in one side of the equal sign.
We see <u>variable x is isolated </u>in the first equation.
In the second equation both of the variables are on the same side so they are not isolated.
Answer:
et the sales done by Mr. Gonzalex each month is
x
.
Then the annual sales are
12
x
.
Thus, since the annual sales are
12
x
, the commission earned is

×
12
x
.
Thus, since Mr Gonzalez want to make $60,000 this year, we get the equation -

Thus, the monthly sales that Mr Gonzalel needs to do are $87,500.
Step-by-step explanation:
18 is 60+35=95 180-95= 85 so ?=85°
Answer:
The length is 9in and the width is 3in
The perimeter is 24in and the area is 27in²
Step-by-step explanation:
To start we have to make 2 equations with the information that gave us the problem
l = length
w = width
w = l - 6in
l = 3w
we replace l in the first equation with (3w)
w = (3w) - 6in
w - 3w = -6in
-2w = -6in
w = -6in / (-2)
w = 3in
now we replace the value of w in the second equation
l = 3w
l = 3 (3in)
l = 9in
Now that we have the length and width we can calculate the perimeter and the area with the following formulas
p = perimeter
a = area
p = 2w + 2h
p = 2(3in) + 2(9in)
p = 6in + 18in
p = 24in
a = w * l
a = 3in * 9in
a = 27in²
Answer:
454.14
Step-by-step explanation:
261 x 174 = 45414
45124/100 = 454.14
