Apply the distributive property to create an equivalent expression.
Bumek [7]

Given:

The expression is

(1-2g+4h)\cdot 5

To find:

The equivalent expression.

Solution:

Distributive property of multiplication over addition is

a(b+c)=ab+ac

Where, a, b and c are real numbers.

We have,

(1-2g+4h)\cdot 5

Using distributive property, we get

=(1)\cdot 5+(-2g)\cdot 5+(4h)\cdot 5

=5-10g+20h

Therefore, the expression 5-10g+20h is equivalent to the given expression.

27x + 24y= 4.5<br><br> 1.5x + y =0.225
Goryan [66]

Answer:

x = 0.1, y = 0.075

Step-by-step explanation:

Given the 2 equations

27x + 24y = 4.5 → (1)

1.5x + y = 0.225 → (2)

Multiplying (2) by - 24 and adding to (1) will eliminate the y- term

- 36x - 24y = - 5.4 → (3)

Add (1) and (3) term by term to eliminate y

- 9x = - 0.9 ( divide both sides by - 9 )

x = 0.1

Substitute x = 0.1 into either of the 2 equations and solve for y

Substituting into (2)

1.5(0.1) + y = 0.225

0.15 + y = 0.225 ( subtract 0.15 from both sides )

y = 0.075
