Just rearrange the inequalities to make x the subject.

2 + y <= 3
Subtract 2 from both sides.
y <= 1

7x > 56
Divide both sides by 7.
x > 8

5x + 6(x - 2) - 8 (x - 3)

Alex Ar [27]

Answer:

The value of $x=-4$ . The figure is also attached below.

Step-by-step explanation:

Considering the expression

$5x + 6(x - 2) - 8 (x - 3)$

If we have to find the vale of $x$ , then

$5x + 6(x - 2) - 8 (x - 3)=0$

$5x+6x-12-8\left(x-3\right)=0$

$5x+6x-12-8x+24=0$

$3x+12=0$

$\mathrm{Subtract\:}12\mathrm{\:from\:both\:sides}$

$3x+12-12=0-12$

$3x=-12$

$\mathrm{Divide\:both\:sides\:by\:}3$

$\frac{3x}{3}=\frac{-12}{3}$

$x=-4$

Therefore, the value of $x=-4$ . The figure is also attached below.

Solve A=1/2bh for h.

GREYUIT [131]

Answer:

h = 2A/b

Step-by-step explanation:

Step 1: Write out triangle formula

A = 1/2bh

Step 2: Multiply 2 on both sides to get rid of fraction

2A = bh

Step 3: Divide both sides by <em>b</em> to isolate <em>h</em>

2A/b = h

Step 4: Rearrange

h = 2A/b
