-7x - 2y = 19

4x + y = -12

Set y equal to each other (opposite signs are fine and you could also set x equal instead of y)

-7x - 2y = 19

8x + 2y = -76

Add equations together

x = -52

Plug x value into an equation

4(-52) + y = -12

Solve for y

-208 + y = -12

y = 196

Hope this helps! ;)

3x - 2 = x + 1
2x = 3
x = 3/2
x = 1.5

3x - 2 = 3(1.5) - 2 = 2.5
or
x + 1 = 1.5 + 1 = 2.5

P = 4(2.5) = 10

perimeter of square is 10 cm so side of square = 2.5cm

The diagram show a 5cm x 6cm x 7cm cuboid pls help you

kotegsom [21]

Answer:

d ≈ 10.5

Step-by-step explanation:

The formula for the diagonal of a retangular prism (cuboid) is

$d=\sqrt{l^2+w^2+h^2}$

1.) Plug in all the values for l, w, and h

$d=\sqrt{5^2+6^2+7^2}$

2.) simplify by squaring the terms inside the square root

5 * 5 = 25

6 * 6 = 36

7 * 7 = 49

$d=\sqrt{25+36+49}$

3.) Add the terms

$d=\sqrt{110}$

4.) Simplify

$d = 10.488$

5.) Round to one decimal place

d ≈ 10.5
