Answer:
Step-by-step explanation:
Part A:
C = 10t + s
Part B:
10(3) + 8
30 + 8 = $38
(28 : 100) *6 = 1.68 (tax)
28 + 1.68 = 29.68 (total cost)
1) 3/5=9/x (cross multiply<span>)
3x=5(9)
3x=45
x=15
2) </span>2/4=x/12 (cross multiply<span>)
</span> 2(12)=4x
24=4x
<span> 6=x
</span>3) 10/x=5/9 (cross multiply<span>)
10(9)=5x
90=5x
18=x

4) 5/6=x/18
5(18)=6x
90=6x
x=15
Answer:
1 1/4
Step-by-step explanation:
You are multiplying a fraction by a mixed number so you have to turn the mixed number into an improper fraction.
2 1/2 -- to do this you have to multiply the denominator by the whole number, then add the numerator.
2*2= 4 4+1=5
2 1/2 = 5/2
Then, you multiply normally
1/2 x 5/2 = 5/4
5/4= 1 1/4
So, you answer would be 1 1/4
