-- On the width:
3 yards = 9 feet
12 inches = another 1 foot
Total width = 10 feet
-- On the length:
8 yards = 24 feet
Ratio of width to length = (10 feet) / (24 feet)
= 5 / 12 .
Answer:
9)x=11 y=3
11)x=18 y=5
Step-by-step explanation:
9) 9x+25=13x+19 13x-19+17y+5=180
9x+44=13x 129+17y=180
44=4x 17y=51
11=x y=3
11) 49+3x=7x-23 3x=11y-1
Answer:
$42
Step-by-step explanation:
Equation: y = 6x
x = number of ice cream cones
y = 6(7) = 42
Answer:
Step-by-step explanation:
a) Area of shape A= 17 (15z+1)
Area of A = 255z+17
b) Area of shape B
One way to find the solution is to take the area of
bigest rectangle ( z+z+8)*(z+4+6)
and subtract the two small rectangles
(z*(14-10)) and
(6*8)
Area of B= [(2z+8)(z+10)] -4z-48
=2z²+ 20z +8z +80 -4z-48 combine like terms
=2z² +24z +32
c) 225z+17 -2z² -24z -32 =
-2z²+201z -15
