Answer:

Step-by-step explanation:
Given that,
The dimensions of a rectangular block = 4 cm x 2 cm x 1.5 cm
Mass, m = 93.6 g
We need to find the density of steel. We know that the density of an object is equal to the mass divided by volume. So,

So, the density of the steel is
.
Answer:
Step-by-step explanation:
To simplify that expression you'll join like terms.
8x + 4 - 5
8x - 1
associative property of multiplication (a * b) * c = a * (b * c)
(3*x) *8 =3*(x*8) is the associative property of multiplication
Answer:
507
Step-by-step explanation:
For the Algebraic Expression,
let the two numbers be X and y
lets assume x = 217
From the question,
217 + y = 724
y = 724-217
y = 507
Therefore, the other number is 507
