Answer:
x=1/8y+9/8
y=<u>y=−8x+9</u>
Step-by-step explanation:
<u>Let's solve for y.</u>
<u>8x+y=9</u>
<u>Step 1: Add -8x to both sides.</u>
<u>8x+y+−8x=9+−8x</u>
<u>y=−8x+9</u>
<u />
<u>Let's solve for x.</u>
<u>8x+y=9</u>
<u>Step 1: Add -y to both sides.</u>
<u>8x+y+−y=9+−y</u>
<u>8x=−y+9</u>
<u>Step 2: Divide both sides by 8.</u>
<u>8x/8=−y+9/8</u>
<u>x=−1/8y+9/8</u>

Answer:
As by the picture, qp is the correct answer.
Step-by-step explanation:
Both are multiplication and in multiplication you can swap the factors and get the same answer every time.
Answer:
25,600
Step-by-step explanation:
You can use the rule of three considering that the number of dolls sold varies directly with the advertising budget:
$54,000 → 9,600
$144,000 → x

x=25,600
According to this, the number of dolls sold if the amount of advertising budget is increased to $144,000 is 25,600.
Answer:
82
Step-by-step explanation:
180+148+xy=360
xy=32
arc=32=double the angle=16 degrees
Since both are radii they are equal. It is an isoceles triangle so angle x equals angle y.
180=16=164/2=82
359 because you start with 100, then you multiply 50 x 359 which equals 17950. But then you are the hundred you had to start with to get 18050
