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:
5 times the sun of 2x and 3y equals the difference of y to the second power and 2x cubed
36 minutes.
(1/20)x+(1/30)x=1solve for x (x=0.8333333333......)
Considering they take the same times for all 3 pounds,
That would mean that since 1 pound takes 12 minutes, then 3 pounds take 36 minutes
Answer:
x = 40
Step-by-step explanation:
The three angles in a triangle add to 180 degrees
x + 30 + (3x-10) = 180
Combine like terms
4x +20 = 180
Subtract 20 from each side
4x+20-20 = 180-20
4x= 160
Divide each side by 4
4x/4 =160/4
x = 40
