Answer:
£289.20
Step-by-step explanation:
13:2 = x:16 or 13/2 = x/16
cross multiply: 208 = 2x
simplify: x = 104
16 blue tiles x £2.80 each = £44.80
104 white tiles x £2.35 each = £244.40
44.80 + 244.40 = £289.20
Answer:
perimeter of rectangles = 2 ( l + b)
34 = 2 ( x + 2 + 3x - 4 )
34 = 2 ( 4x - 2 )
34 = 8x - 4
38 = 8 x
38/ 8 = x
thus , x = 4.75 inches
Answer: (11, -1, -17)
Step-by-step explanation:
4x+y=3
4(-2)+y=3
-8+y=3
y=3+8
y=11
4x+y=3
4.1+y=3
4+y=3
y=3-4
y=-1
4x+y=3
4.5+y=3
20+y=3
y=3-20
y= -17
Answer:
224
Step-by-step explanation:
64*3.5=224
Answer:
16π/9
Step-by-step explanation:
40°/360° = 1/9
