Answer:
x:y:z = 12:3:2
Step-by-step explanation:
x = 4y
2y = 3z ⇒ 4y = 6z
⇒ x = 4y = 6z
To find x:
Multiply the coefficients of y & z: 4 × 6 = 24
To find y:
Multiply the coefficients of x & z: 1 × 6 = 6
To find z:
Multiply the coefficients of x & y: 1 × 4 = 4
⇒ x:y:z = 24:6:4 = 12:3:2
(x/2) + 1 = -5.......add -1 to both sides
x/2 = -5 - 1
x/2 = -6 .....multiply both sides by 2
x = -6 * 2
x = -12
Step-by-step explanation:
An integer is a number that can be written without a fractional component.
A rational number is a number that can be represented as a fraction with a non-zero denominator, and its decimal expansion is finite or infinite and repeat.
An irrational number is a real number which is not a rational number.

Answer:
222cm3
Step-by-step explanation:
9cm × 3cm × 6cm = 162cm
8cm - 3cm = 5cm
5cm × 2cm × 6cm = 60cm3
162cm3 + 60cm3 = 222cm3
Volume = 222cm3
