Question

ladessa [460]

Answer:

Step-by-step explanation:

4s + 2j = 68........2j = -4s + 68........j = -2s + 34

3s + 3j = 81

3s + 3(-2s + 34) = 81

3s - 6s + 102 = 81

3s - 6s = 81 - 102

-3s = - 21

s = -21/-3

s = 7 <==== shirts cost 7 bucks

j = -2s + 34

j = -2(7) + 34

j = -14 + 34

j = 20 <===== jeans cost 20 bucks

-1/2x+2=-x+7 i need to know

ludmilkaskok [199]

$= \frac{ - 1}{ \: \: 2} x + 2 = x + 7$

$= \frac{ - 1}{ \: \: \: 2} x + 2 - x = 7$

$= \frac{ - 3}{ \: \: \: 2}x + 2 = 7$

$= \frac{ - 3}{ \: \ \: 2}x = 7 - 2$

$= \frac{ - 3}{ \: \: \: 2} x = 5$

$x = 5 \: \div \frac{ - 3}{ \: \: \: 2}$

$x = 5 \times \frac{ \: \: \: 2}{ - 3}$

$x = \frac{ - 10}{ \: \: \: 3}$

$∴ \frac{ - 1}{ \: \: \: 2} \times \frac{ - 10}{ \: \: \: 3} = \frac{ - 10}{ \: \: \: 3} + 7$

I need help with math the question is

velikii [3]

Answer:

$P=2(S-lw)/h$

Step-by-step explanation:

we have that

The formula for the surface area of the enclosed space is

$S=lw+0.5Ph$

Solve for P

That means ------> isolate the variable P

Subtract lw both sides

$S-lw=lw+0.5Ph-lw$

$S-lw=0.5Ph$

Multiply by 2 both sides

$2(S-lw)=(2)0.5Ph$

$2(S-lw)=Ph$

Divide by h both sides

$2(S-lw)/h=Ph/h$

$2(S-lw)/h=P$

Rewrite

$P=2(S-lw)/h$
