6(t-3)=2(9-2t)=
We move all terms to the left:
6(t-3)-(2(9-2t))=0
We add all the numbers together, and all the variables
6(t-3)-(2(-2t+9))=0
We multiply parentheses
6t-(2(-2t+9))-18=0
We calculate terms in parentheses: -(2(-2t+9)), so:
2(-2t+9)
We multiply parentheses
-4t+18
Back to the equation:
-(-4t+18)
We get rid of parentheses
6t+4t-18-18=0
We add all the numbers together, and all the variables
10t-36=0
We move all terms containing t to the left, all other terms to the right
10t=36
t=36/10
<h2>
t=3+3/5</h2>
Answer:
Step-by-step explanation:
The ratio= 1:4
X amount over 41.67 is 60/100
x = 60
---- ------
41.67 100
100x = 2500.20
------ --------
100 100
x=25
plug in to check
25/41.67 = 60/100
0.6 = 0.6
remember that you have to do the same to both sides
minus 16 both sides
mulitply both sides by 4
P represents the original per pound price3p represents the cost of three pounds 3p + 3(0.75) = 5.88 multiply3p + 2.25 = 5.88 subtract 2.55 from both sides3p = 3.63 divide both sidesby 3p = 1.21 The original price was $1.21 per pound. 1.21 = 0.751.963(1.96)5.88
