Step-by-step explanation:
Let the number of singing act be x
Let the number of comedy act be y
If the total act is 14, then;
x+y = 14..... 1
If singing acts are 4.5 minutes long and comedy acts are 3.5 minutes long and the acts lasts 59 minutes, then:
4.5x + 3.5y = 59 .......... 2
Solve both equation simultaneously for x and y
x+y = 14
45x+35y = 590
.................................
x+y = 14......... *9
9x+7y = 118....... 1
...............................
9x+9y = 126
9x+7y = 118
Subtract both equations
9y-7y = 126-118
2y = 8
y = 8/2
y = 4
Substitute y = 4 into equation 1;
From 1: x+y = 14
x+4 = 14
x = 14-4
x =10
Hence there are 10 singing acts and 4 comedy acts in the show
Let's turn this sentence into an equation:
8n = -n + 36
Then solve:
9n = 36 => n=4
X/3-10=12
x/3=-2
x=-6
p/5+10=14
p/5=4
p=20
Answer:
I used Desmos. Heres a picture of what its supposed to look like.
Step-by-step explanation:
now, he had 3200, he took 1500 for deposit, so, 3200 - 1500, he had left in his pocket 1700.
so after 5 years, he'll have 1700 + 1800.
