Which value of d is a solution to equation 2.2d + 5.4= 12

ryzh [129]

Hello!

Answer:

d=3

*The answer must have a positive sign.*

Step-by-step explanation:

Distributive property: a(b+c)=ab+ac

First, you multiply by 10 from both sides of an equation.

$2.2d*10+5.4*10=12*10$

Then, you had to refine the problem down.

$22d+54=120$

Next, you subtract by 54 from both sides of an equation.

$22d+54-54=120-54$

Simplify.

$22d=66$

You can also divide by 22 from both sides of an equation.

$\frac{22d}{22}=\frac{66}{22}$

And finally, simplify and solve. You can also divide by the numbers.

$66/22=3$

Final answer: → $d=3$

Hope this helps!

Thanks!

If p + q = 36, and p -q = 20, then q = ?

Andrew [12]

Answer:

q = 8

Step-by-step explanation:

Given the 2 equations

p + q = 36 → (1)

p - q = 20 → (2)

Add the 2 equations term by term

2p = 56 ( divide both sides by 2 )

p = 28

Substitute p = 28 into (1)

28 + q = 36 ( subtract 28 from both sides )

q = 8
