3x + 5x = 320
8x = 320
x = 40
3(40) : 5(40) = 120 : 200
The best answer would be Option C.
Answer:
x = ±9
Step-by-step explanation:
x² - 55 = 26
<u>+55 + 55</u>
x² = 81
x = √81
x = ± 9
Step-by-step explanation:
→ P = 2L + 2W
→ P = 2(L + W)
→ P ÷ 2 = L + W
→<u> (P ÷ 2) - W = L</u>
We can use this formula to to calculate the length.
Answer:
$240.74
Step-by-step explanation:
--Starting with the initial amount: $299.99.
--Discount of 25% is found by multiplying to initial value. 25% is the same as .25, so $299.99 * .25 = $74.9975. Subtract initial from discount: $299.99 - $74.9975 = %224.9925.
--Tax: same thing with multiplying, 7% tax is equal to .07, so $224.9925 * .07 = $15.749475. Add this to the discounted amount: $224.9925 + $15.749475 = $240.741975.
--Round answer to dollar format: $240.74
Hope this helps!
