Answer:

29 feet above sea level

Step-by-step explanation:

One floor is 9 feet high, so the top of the first floor will be 9 feet above the ground.

The ground is also 20 feet above sea level, so add 9 to this to find how many feet above sea level the top of the first floor is:

20 + 9

= 29 feet above sea level

Answer:

14<36

Step-by-step explanation:

5(y=2)^2-2x < (x=3)^2

5(2)^2 < (3)^2

5*2 = 10

10^2 = 20

-----------------------------------------

2(x=3)

2(3)=6

______________________

Put the first part together

20-6 = 14

Other side

3*2 = 6

Put all of it together

14<6+1 or any number lower than 7

Help please..! I need the answer to this thank you.
torisob [31]

1. The additive identity is 0. This is because adding 0 to anything leads to the same value. Example: 0+3 = 3.

2. An equation is where you have two expressions separated by an equal sign. In your case it would be "a mathematical sentence whose verb is 'equal' (=)"

3. The multiplicative identity is 1. Multiply 1 with any number and the result is that same number. Example: 1*7 = 7.

4. An open sentence is an equation that contains one or more variables. An example would be x+2 = 4. The reason why we call it open is because the true or false nature of the sentence is up in the air until we know what x is. If we knew that x = 3 for instance, then x+2 = 4 would be false since 3+2 = 4 is false. If we nailed down what x was then it would go from open to closed.

5. The symmetric property is that if a = b then b = a. Think of a mirror how the image reverses.

It's a little blurry sorry please help
Ghella [55]

<u>Answer:</u>

It's X=2

<u>Working out:</u>

<u>(left one):</u>

2(x+3)=10

2x+6=10

2x=10-6

2x=4

x=2

Working out:

(right one):

2(x+3) must be all divided by 2 so it will be x+3 and same for 10, it will be 5 so...

x+3=5

x=5-3

x=2

Hope it helps ^---^
