Answer:
15x-2=8x+1
13x=9x
i think that's correct im not sure but i hope to help u :)
Answer:
Angle A: 40°
Angle B: 50°
Angle C: 90°
Side A: 14
Side B: 12
Side C: 11.2 or 11 if you round to the nearest whole number.
Step-by-step explanation:
Angle A;
Since we know angles B and C we can use those to help us find angle since all three angles should add up to 180°.
90-50=40
Angle A= 40°
Side C;
Since we know all the angles now and the other two side lengths, we will use those to help us find Side C.
cos 40°= C/14
C/14= cos 40°
C/14= .8
C= .8 x 14
C= 11.2
Hope this helps! Have a great day! :)
Answer:
V = 672cm^3
Step-by-step explanation:
V of irregular figure = lwh + lwh
V = 7(3)(2) + 10(7)(9)
V = 42 + 630
V = 672cm^3
Answer: r = 4
Step-by-step explanation:
V = pi * r^2 * h
144 * pi = pi * r^2 * 9
Divide by pi
144 = r^2 * 9
Divide by 9
16 = r^2
Take square root of both sides
rad(16) = rad(r^2)
4 = r
r = 4
The answer is m = 7.
1. (<span>13−m=2(m−4) </span>Regroup terms
2. Expand (<span>13−m=2m−<span>8)
3. </span></span>Add <span><span>m</span></span> to both sides (<span>13=2m−8+<span>m)
4. </span></span>Simplify (<span>2m−8+m</span> to <span><span><span>3m−8)
5. add 8 to both sides (13 + 8 = 3m)
6. </span></span></span>Simplify <span>13+8 to 21
7. </span>Divide both sides by <span><span>33</span></span> (21/3 = m)
8. simplify 21/3 to 7 (7 = m)
9. switch sides ( finally m = 7)
