Answer:

X=24

Step-by-step explanation:

3(2x-a)=2(3x+12)

6x-3a=6x+24

-6x both sides.

-3a=x+24

Get rid of the -3a.

x+24

divide by x both sides.

x=24

Answer: a = -8

3(2x - a) = 2(3x + 12)

⇔ 6x - 3a = 6x + 24

⇔ - 3a = 24

⇔ a = -8

Sam practices his guitar for 9 hours each week he practices each song for 3 1/2 hours. What is the greatest number of song he ca

liberstina [14]

Answer:

<em>The greatest number of song he can practice in a week is 2.</em>

Step-by-step explanation:

Suppose, the greatest number of song he can practice in a week is $x$

He practices each song for $3\frac{1}{2}$ hours. So, the total time required for practicing $x$ number of songs $= (3\frac{1}{2}*x)$ hours.

Given that, he practices his guitar for 9 hours each week.

So, the equation will be......

$3\frac{1}{2}*x= 9\\ \\ x= 9\div 3\frac{1}{2}\\ \\ x=9\div \frac{7}{2}=9 \times \frac{2}{7}=\frac{18}{7}= 2.571.... \approx 2$

<em>(Rounded as the greatest whole number)</em>

Thus, the greatest number of song he can practice in a week is 2.

Need help on this, need help now D:

baherus [9]

Answer:

$\sqrt{34}$

Step-by-step explanation:

Calculate the distance using the distance formula

d = √ (x₂ - x₁ )² + (y₂ - y₁ )²

with (x₁, y₁ ) = A(- 2, 5) and (x₂, y₂ ) = B(3, 8)

d = $\sqrt{(3+2)^2+(8-5)^2}$

= $\sqrt{5^2+3^2}$

= $\sqrt{25+9}$

= $\sqrt{34}$

Elena L [17]

Answer:

The first one is 75 and the second one is 81

Step-by-step explanation:

put 187.5 into calculator then divide it by the bottom number/denominator in this case 2.5 and then you get 75

put 303.75 into calculator then divide it by the denominator or 3.75 and you get an answer of 81

so 81 miles per hour

PLEASE ANSWER!! i-READY!!! The system of equations 2y = 14 - 2x and y = -x + 7 is graphed is graphed. What is the solution to th

Vladimir [108]

$y = - x + 7 \\ 2y = 14 - 2x \\ \\ 2( - x + 7) = 14 - 2x \\ - 2x + 14 = 14 - 2x \\ 14 = 14$
Since 14 does equal 14, the answer will be D.
