Solve the simultaneous equations3x-5y=5 and x+10y=4

1 answer:

7 0

3x - 5y = 5 ——> 6x - 10y = 10

6x - 10y = 10
x + 10y = 4
——————-
5x = 6
x = 1.2

1.2 + 10y = 4
10y = 2.8
y = 0.28

so, x = 1.2 and y = 0.28

hope this helps :)

Answer: 178.3

Step-by-step explanation:

Use cos to find the value of x: cos(27)=350/x

You will find x = 392.81

Using this value, find sin(27): Sin(27)=y/392.81

You will find y=178.33

Rounding to the nearest tenth, you get 178.3

Answer: D) 602.88

Step-by-step explanation:

A cylinder is basically a circle prism. Any prism volume can be found by taking the area of the base * the height. The circle area is 4^2*3.14 = 50.24. Then multiply that by the height(12) 50.24*12 = 602.88

Also, so far all of your questions that I've answered have been D...
