4*6=24-6*3=6+8=14
if you multiply 4 and 6 it equals 24 subtract the sum of 6 times 3{ which is 18] it gives you 6 and then you add 8

Hello there!

Now, just multiply 9 with 10 = 9 x 10 = 90
Your pay for 10 hours was $90
I hope I helped!

The Area of Shaded region is equal to the difference in Area of rectangle and Area of triangle .

let's solve for area of rectangle :

$➢ \: \: length \times width$

$\longrightarrow8 \times 3x$

$\longrightarrow24x$

Now, Area of Triangle :

$➢ \: \dfrac{1}{2} \times base \times height$

$\longrightarrow \dfrac{1}{2} \times 4 \times x$

$\longrightarrow2x$

So, the area of the shaded region in terms of x :

$\longrightarrow24x - 2x$

$\longrightarrow22x$

And since, Area of Shaded region = 44 cm²

By equating the area, we get

$\large \boxed{ \boxed{22x = 44}}$

Value of x = 2

How do I solve this .... question in the image. <br><br>thank you

Answer:

Below

Step-by-step explanation:

● x-20 = y+20 (1)

● 2(y-22) = x+22 (2)

This is a system of simulataneous equations

Let's simplify the expressions first

● x -20 = y + 20 (1)

Add 20 to both sides

● x -20 + 20 = y+20 +20

● x = y + 40 (1)

● 2(y-22) = x+22 (2)

● 2y - 44 = x +22

Substrat 22 from both sides

● 2y-44-22 = x+22-22

● 2y -66 = x (2)

This is the new system:

● x = y+40 (1)

● x = 2y-66 (2)

Substract (2) from (1)

● x-x = y+40-(2y-66)

● y+40-2y+66 = 0

● -y +106 = 0

● y = 106

Replace y with 106 in (1)

● x = y +40

● x = 106+40

● x = 146

So the solutions are (146,106)
