Since you didn't give the options, we'll answer In steps and you can pick which step you have as an answer choice...
16 = -9 + z
Add 9 to each side for
16 + 9 = z (that's one option)
Add like terms for
25 = z (there's another)
You could also go a whole different route and take the original equation
16 = -9 + z
subtract z from each side for
16 - z = -9
Any of those would be another way to express the equation.
Answer:
x=8
Step-by-step explanation:
5(x/2+3)=35
x/2+3=35/5
x/2+3=7
x/2=7-3
x/2=4
x=4*2
x=8
3x + 2y = 12
5x - 2y = 4
When adding the 2 equations, the y's will cancel.
8x = 16 divide both sides by 8.
X= 2
Answer/Step-by-step explanation:
Given:
Seven more than the quotient of a number b and 45 is greater than 5
So:
Seven more than the quotient of a number b and 45 is greater than 5
=
7 + b/45 > 5

<u><em>~Lenvy~</em></u>
Answer:
The scale factor is k = 1/30
a)
<u>The length of the wing on the model:</u>
- 9 m * 1/30 = 900 cm * 1/30 = 30 cm
b)
<u>The area of the tail section of the plane:</u>
- 80 cm² : (1/30)² =
- 80 cm² * 900 =
- 72000 cm² =
- 72000 * (1/100)² m² =
- 7.2 m²
