G=6
you want to move the variable to the left side and change its sign so the equation should now be 3.4g-1.4g+7=19, then you want to collect the like terms which now you should be left with 2g=19-7, which then turns into 2g=12, finally you want to divide both sides of the equation by 2, so then you are left with g=6.
for the second question x= 0
you want to cancel equal terms,then collect the like terms -3x=5x-10x, then move variable to the left 3x=-5x, collect like terms again -3x+5x=0, divided both sides by 2 so 2x=0, and then you’re left with 0=x

Answer:

for #1 its the 1st and 4th box

for # 2 it's 13.5 and 20.25

Step-by-step explanation:

1st box - 10 ÷ 5 = 2 and 25 ÷ 5 = 5

4th box - 10 x 2 = 20 and 25 x 2 = 50

you have to make sure that you do the same thing for both sides of the equation

6 x 2.25 = 13.5

9 x 2.25 = 20.25

Dilation is an enlarging or shrinking of a math figure using a specific scale factor

multiply your numbers by that given scale factor to give you your answer of option 2

hope this is right I'm not completely positive about the send one.

Hello!

I've attached the diagram.

For this problem, since you have a right triangle, you can use the Pythagorean Theorem to fine the length of the ladder (the hypotenuse of the triangle).

Pythagorean Theorem (where c is the hypotenuse):
a² + b² = c²

The triangle's leg lengths are 8 and 6; substitute into the theorem:
8² + 6² = c²

Simplify:
64 + 36 = c²
100 = c²
10 = c

Answer:
The length of the ladder is 10 m.
