Step-by-step explanation:
1 yard = 3 feet
so 5 feet would = to 1 2/3 yards = 5/3 yards
12.99*5/3
12 99/100=1299/100
1299/100 x 5/3=433/20
433/20 = 21 13/20
13/20 x 5/5= 65/100=0.65
0.65+21
$21.65
hope this helped!
have a good day!

Answer:
a = -2
b = 7
Step-by-step explanation:
5a+3b=11
-2a+3=b
substitute for b:
5a + 3(-2a + 3) = 11
5a -6a + 9 = 11
-a = 2
a = -2
b = 7

Answer:
y = 14.5
Step-by-step explanation:
given that y varies directly as x
mathematically,
y ∝ x
y = kx .............................................. where k is the constant of proportionality.
k = y /x
given that
y = 79
x = 49
k = 79/49
k = 1.61
to find y when x = 9
from
y = kx
y = 1.61 × 9
y = 14.5
therefore the value of y when x = 9 in ths variation is evaluated to be equals to 14.5
