7 shirts because you simply divide 290 by 40=7.25 but of course you can’t have “7.25” shirts so the answer should be 7

Answer:

7 shirts

Step-by-step explanation:

290/40 = 7.25

But since you can't have 7.25 shirts, it's just 7.

Help on this math question please explain how you got the answer
Julli [10]

Answer:

Store C has the lowest price of $7.00

Step-by-step explanation:

Store A's sale gets you 15% off the shoes. 15% of 35 is $25.50

Store B's sale gets you $5.00 off the shoes. $35.00 - $5.00 = $30.00

Store C's sale gets you 1/5 off the shoes. 1/5 of $35.00 is $7.00

That means that the only true statement is the Store C's shoes are $7.00

Hope this helps you for next time you get a problem like this.

3xy'+y=12x find general solution
Eduardwww [97]
The equation is linear, as you can write

3xy'+y=12x\implies y'+\dfrac1{3x}y=4

An integrating factor would be

\mu(x)=\exp\left(\displaystyle\int\frac{\mathrm dx}{3x}\right)=x^{1/3}

Multiplying both sides of the ODE by this yields

x^{1/3}y'+\dfrac1{3x^{2/3}}y=4x^{1/3}

where the LHS is a derivative:

\dfrac{\mathrm d}{\mathrm dx}\left[x^{1/3}y\right]=4x^{1/3}

Integrating both sides, we get

x^{1/3}y=4\displaystyle\int x^{1/3}\,\mathrm dx
x^{1/3}y=3x^{4/3}+C
y=3x^{3/3}+Cx^{-1/3}=3x+\dfrac C{x^{1/3}}
