Answer:

x = 2

Step-by-step explanation:

180= 90 + 57 + Z

Z = 180 - 90 - 57

Z = 33

33 = 7X + 19

7X = 33 - 19

7X = 14

X = 2

2x + y = 3 x = 2y - 1

Ad libitum [116K]

2x+ y = 3
x = 2y - 1
Make sure there are NO SPACES in your answer. Include a comma in your answer.
It looks like I could substitute the x=2y-1. Into 2x+y=3
2(2y-1)+y=3
4y-2+y=3
5y=5
y=1
x=2(1)-1
x=1

(1,1)
CHECK
2x+y=3
2(1)+(1)=3
2+1=3
3=3
Left hand side=Right hand side
Check other equation
x=2y-1
1=2(1)-1
1=1
Therefore the solution is (1,1). Since the left hand side= right hand side in each equation

Please help asap!!!!!!!! Number 2 and 3

romanna [79]

Answer:

Step-by-step explanation:

2) r = 16/2 = 8 cm

Area of top and bottom = 2*πr²

= 2 * 3.14 * 8 * 8

= 401.92 cm²

Midlle part = h * πd

= 6 * 3.14 * 16

= 301.44 cm²

Total = 401.92 + 301.44

= 703.36 cm²

3) Area of front and back = $2* \frac{1}{2}*b * h\\$

$= 2*\frac{1}{2} * 3 * 4\\\\= 12 cm^{2}$

Area of bottom = length * breadth

= 12* 3

= 36 cm²

Area of left = 12 * 4

= 48 cm²

Area of right = 12 * 5 = 60 cm²

Total = 12 + 36 + 48 + 60 = 156cm²
