Answer:
17x + 8
Step-by-step explanation:
4(3x + 2) + 5x
12x + 8 + 5x
17x + 8
Step-by-step explanation:
a-³/b-²
b²/a³ = 6²/5³ = 36/125
Answer:
Step-by-step explanation:
(a) You use the fact that the lengths RS and ST total the length RT.
RS +ST = RT
(6y+3) +(3y+5) = 80 . . . . . substitute the given values
9y +8 = 80 . . . . . . . . . . . . .simplify
9y = 72 . . . . . . . . . . . . . . . .subtract 8
72/9 = y = 8 . . . . . . . . . . . .divide by the coefficient of y
___
(b) Now, the value of y can be substituted into the expressions for RS and ST to find their lengths.
RS = 6y +3 = 6·8 +3
RS = 51
ST = 3y +5 = 3·8 +5
ST = 29
___
<em>Check</em>
RS +ST = 51 +29 = 80 = RT . . . . the numbers check OK
