Angeline bought s yards of satin fabric priced at $8.09 per yard, and c yards of cotton fabric priced at $3.79 per yard. What expression could you use to determine the total cost of the fabric? If she bought 5 yards of satin fabric and 8 yards of cotton fabric, how much did Angeline spend in all?

$70.77

Step-by-step explanation:

Cost of 's' yards of satin fabric= 8.09*s = 8.09s

Cost of 'c' yard of cotton fabric = 3.79 * c = 3.79c

Total cost of fabric = 8.09s + 3.79c

s = 5 yards ;  c = 8 yards

Plugin the value of s and c in expression,

8.09*5 + 3.79*8 = 40.45 + 30.32

                          = $ 70.77

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
