800 + 16x = 720 + 21x. Cancel out the 720 to get 80 + 16x = 21x. Subtract 16x from both sides to get 80 = 5x. Divide by 5 to get 16 = x, or x = 16. 16 hours. The charge is 800 + 16(16), = 720 + 21(16) which = 800 + 256 = 720 + 336 which = 1,056 = 1,056. Hope this helped!
Hello,
Yes since (2*6.4)²+9.6²=256=16²
Angle A=90°
Solving is :
X=2
Y=1
Step by step
(2x-3) + 5 = 3x
2x+2=3x
X=2
Substitute x by 2
Y=1
The answer a are
1 C
2 A
3 whatever letter has the the answer 5x10^10
