Can anyone help me?

I've tried it
but dont get
it

Step-by-step explanation:

1. Convert meters into centimeters:

Nour's structure = 970 cm

Maha's structure = 9.5 meters

1 meter = 100 cm

9.5 · 100 = 950 cm

Result:

Nour's structure: 970 cm

Maha's structure: 950 cm

Nour's structure is 20 cm taller than Maha's structure.

2. Convert meters into centimeters:

Nour's structure: 970 cm + 150 cm = 1120 cm

Maha's structure: 950 cm + 1.05 meters = x

1.05 meters · 100 = 105 cm

Result:

Nour's structure: 970 cm + 150 cm = 1120 cm

Maha's structure: 950 cm + 105 cm = 1055 cm

Nour's structure is 65 cm taller than Maha's structure

Note:

Feel free to comment if you have any questions!

5=812a+9+3

step 1: simplify both sides of the equation.

5=812a+9+3

5=(812a)+(9+3)(combine like terms)

5=812a+12

5=812a+12

step 2: flip the equation.

812a+12=5

step 3: subtract 12 from both sides.

812a+12−12=5−12

812a=−7

step 4: divide both sides by 812.

812a /812 = -7/812

a= -1/116

so the answer is

a=   -1/116

two? xd
