Answer:
x + y = 20
1.5x + 5y = 54.50
Solve the equations and get: x = 13 ∧ y = 7
Marcy bought 13 books and 7 CDs.
91 worms. 7 boxes multiplied by 13 worms per box equals 91 worms left in the shop
<u>To find the cost of Senior T-shirts needed, </u><em>Multiply (the number of students) by (how much each T-shirt costs).
</em>
350 × 7.2 = $2520
<u>To find the cost of the yearbooks needed,
</u><em>Multiply (the number of students) by (how much each yearbook costs).
</em>
350 × 24.75 = $8662.5
<u>Now, find the TOTAL money the Student government has to pay.
</u><em>Add up the two sums.
</em>
2520 + 8662.5 = $11182.5
<em><u /></em>
<em>SO, the answer is
</em>
<u>$11182.5</u>

Step-by-step explanation:
Answer:
(x - 3)² + (y + 4)² = 49
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + *y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
Here (h, k) = (3, - 4) and r = 7 , then
(x - 3)² + (y - (- 4) )² = 7² , that is
(x - 3)² + (y + 4)² = 49 ← equation of circle
