Answer:
5c - 3 (4a)
Step-by-step explanation:
If you're just grouping and adding them together you would get 5c - 3 (4a).
$350= $130+$20x, x= amount of weeks
$350-$130=$220 $20*11=220
Answer: 11 weeks
Answer:
x=34
Step-by-step explanation:
1. formula for Pythagorean Theorem for right trangles is <u>a^2+b^2=c^2</u>
2. a=30 and b=16, so (30)^2+(16)^2=c^2
3. (30)^2=900 and (16)^2=256
4. 900+256=1156
5. 1156=c^2
6. ![\sqrt{1156} =\sqrt{c^2}](https://tex.z-dn.net/?f=%5Csqrt%7B1156%7D%20%3D%5Csqrt%7Bc%5E2%7D)
7. the square root of 1156 is 34, so c=34
8. The missing side of the triangle, labeled as "x<em>"</em> is 34
Answer:
E
Step-by-step explanation:
dy/dt = y² − 1
When -1 < y < 1, dy/dt is negative. So the solution is decreasing between y = -1 and y = 1.
Only one graph is consistently decreasing in that range, and that's the last graph.
Since the angles are complementary, they add to 90°. So we can write the equation:
x represents the first angle, and 4x represents the second
x+4x=90
5x=90
x=18
So the first angle is 18° and the second is 72° (18*4)
Hope this helps
