Since it’s in percents, put the percent over 100 as a fraction and simplify them. For percents that aren’t given, add the rest and subtract it from 100 and then place it as a fraction over 100
Answer:
Sue = 25.75
Dave = 29.5
Tom = 19.75
Sue = s
Tom = t
Dave = d
Step-by-step explanation:
s+t+d = 75
s-6=t
d +16 = s+t
d+16+d= 75
2d = 59
d = 29.5
t = s-6
t+s = 45.5
s-6+s= 45.5
2s = 51.5
s= 25.75
t= 19.75
You doo 100 plus 10x wich would be 200 witch means x cubed = 200 then you do the cube root of 200 wich is 5.8
GIVEN:
Cost of a taco and a cup of tea = $2.10
Cost of 2 tacos and 3 cup of tea = $5.15
ANSWER:
On solving eq(1), we get
Substitute the value of x in eq(2), we get
- 2(2.10 – y) + 3y = 5.15
- 4.20 – 2y + 3y = 5.15
- y = 5.15 – 4.20
- y = 0.95
So, x = 2.10 – 0.95
Hence, Cost of a taco is $1.15
So, <u>Correct choice</u> - [E] $1.15
