Im not sure about the second one, but for the first one, Alex’s height is 167.64 cm. :)
Notice the 7) 1st sequence, and the 8) second one
Answer:
B
Step-by-step explanation:
Plug in all the values for x & y into the equation y=2x+3 (B). 2*2=4. 4+3=7. All the other values for x & y match up perfectly as well. The answer is B
Answer:
En este caso 70 ° y 20 ° son complementarios porque 70° + 20° = 90°.
Más ejemplos podrían ser 47° y 43°, ya que 47° + 43° = 90°, 30° y 60°, 45° y 45° , etc.
Dos ángulos son suplementarios si su suma forma un ángulo llano, es decir, 180°.
Answer:
<h2>
X = 4.5</h2>
Step-by-step explanation:
So we have two equations.
y=35x+40
y=40x+17.5
We want to find the coordinates in which they intersect.
BUT They never intersect, They are parallel to each other leaving us with a
NO SOLUTION
When you are trying to solve for x you want to get rid of the y's and simply put on your paper: 35x+40 = 40x+17.5
Then you distribute, in which I am not going to show because that too many steps lol. But you'll get:
x=4.5
