Answer:
3
Step-by-step explanation:
All of these numbers are close to each other except 3.
Answer:
To write this down as an algebraic expression you would simply need to multiply the two terms together.
So in this case it would be 8 multiples by x which is 8x
Step-by-step explanation:
1) Find out the variables in the Expression
2) Find the operation that is done to the variables
3) Apply the operation to those variables.
Answer: x = 60°
Step-by-step explanation:
We know a circle is equal to 360°, so we can subtract from 360° to find x using vertical angles and other given details.
Vertical (opposite) angles are equal to each other. This is why, for example, we know AGE and FGC are both 30°.
See attached for a breakdown of the angles.
360° - 30° - 30° - 90° - 90° = 2x
120° = 2x
60° = x
-0.5g-1.5=-6.5
We move all terms to the left:
-0.5g-1.5-(-6.5)=0
We add all the numbers together, and all the variables
-0.5g+5=0
We move all terms containing g to the left, all other terms to the right
-0.5g=-5
g=-5/-0.5
g=+10
Answer:
You need: 420 mL pure water and 35 mL of the 65% solution
Step-by-step explanation:
let 65% alcohol mixture = x mL
y = water
x + y = 455
0.65x / 455 = 0.05
0.65x = 22.75
x = 35
recall, 35 + y = 455
y = 420
You need: 420 mL pure water and 35 mL of the 65% solution
