Answer:
<span>y=−24</span>
Explanation:
<span><span>18</span><span>(5y+64)</span>=<span>14</span><span>(2y+20)</span></span>
multiply both sides by 8:
<span>5y+64=2<span>(2y+20)</span></span>
multiply out brackets:
<span>5y+64=4y+40</span>
subtract 4y from both sides:
<span>y+64=40</span>
subtract 64:
<span>y=40−64=−24</span>
<span>y=−<span>24
</span></span>
Answer:
(2) and (3)
Step-by-step explanation:
(2) shows the total cost of the flowers, minus 10% of the total cost, and 100% - 10% = 90%
(3) shows them taking 90% of the total cost, just like (2)
Answer:169.7
Step-by-step explanation:
To find the volume of a cylinder you can use the math formula πr^2H where r is the radius and H is the height. If you plug in the values you get π3^2(6) simplify 3^2 to get (9π)(6), you can multiply 9 by 6 to get 54 then multiply that by 3.1415 to get 169.65 which rounds to 169.7
Your answer is no solution (because a negative square root doesn't exist)
first, you divide all sides by five and then take b, half it then square it
