Answer:
z = 21 ; y= 16
Step-by-step explanation:
first of all we have to isolate a variable.
In second expression we can obtain:
3y = 2z+6
y = 2/3 z + 2
now we have to substitute this value in the first equation and solve it
8(2/3z+2)-5z = 23
16/3z + 16 -5z = 23
16z +48 - 15z = 69
z = 21
now we have to substitute z in the second equation:
y = 2/3 (21) +2
y = 14+ 2 = 16
y = 16
Answer:
Polygons are named according to the number of sides and angles they have. The most familiar polygons are the triangle, the rectangle, and the square. A regular polygon is one that has equal sides. Polygons also have diagonals, which are segments that join two vertices and are not sides.
1/2 x s, where s equals 3/10 means,
(1/2) x (3/10) which will give (3/20)
You simply multiply the numerators to get 3 and the denominators to get 20.
The blue ray and the tv combined is 490 so just divide by 2 there’s your answer bud
Answer:
Step-by-step explanation:
B = 3V/h
Multiply by h on both sides
Bh = 3V
V = Bh/3
