Is 7 a solution of 5x - 3 = 12?
V125BC [204]

Answer:

no

Step-by-step explanation:

The scale on a drawing of a swimming pool is 1cm=4m. What is the actual length of the pool if it's 10cm long on the drawing
Usimov [2.4K]

1 cm was multiplied by ten, so wee need to do that on the other side too.

1 times 10 = 10 cm, so 4 times 10 = 40 meters,
So your answer is 40 meters. Hope it helps!

I need help answering this question..​
Irina-Kira [14]

Answer:

x=3

Step-by-step explanation:

Given: 15=7x-6

To solve this equation, we need to isolate x on one side of the equation algebraically. I see that we have like terms, but they are on opposite sides of the equal sign. Let's add 6 to both sides.

21=7x

To isolate x, divide both sides by 7.

x=3
