Answer:

no solutions

Step-by-step explanation:

3x+ 7(x+1) = 2(6x+5) -2x

Distribute

3x+7x+7 = 12x+10-2x

Combine like terms

10x+7 = 10x+10

Subtract 10 from each side

10x+7-10x = 10x+10-10x

7 = 10

This is not a true statement so there are no solutions

A 240hp automobile engine delivers 195hp to the drive wheels, what is the effciency of the transmission and drive mechanism?

sweet-ann [11.9K]

Answer:

81.25%

Step-by-step explanation:

Given that :

Engine power = 240 hp

Power delivered to drive wheel = 195 hp

Efficiency = (power delivered to drive wheel / Engine power) * 100%

Efficiency = (195 / 240) * 100%

Efficiency = 0.8125 * 100%

Efficiency = 81.25%

The efficiency of transmission and drive mechanism is 81.25%

Solve for t: if a≠−b t + <img src="https://tex.z-dn.net/?f=%5Cfrac%7Bat%7D%7Bb%7D" id="TexFormula1" title="\frac{at}{b}" alt

prohojiy [21]

Answer:

$t=\frac{b}{b+a}$

Step-by-step explanation:

we have

$t+\frac{at}{b}=1$

Solve for t

That means ----> Isolate the variable t

Multiply by b both sides to remove the fraction

$bt+at=b$

Factor the variable t in the left side

$t[b+a]=b$

Divide by (b+a) both sides

$t=\frac{b}{b+a}$
