Answer:
w = -8
Step-by-step explanation:
step 1:(20 - 9w) - 4 • (15 - w) = 0
step 2: -5w - 40 = -5 • (w + 8)
step 3: -5 • (w + 8) = 0
step 4: Subtract 8 from both sides of the equation :
w = -8
Answer:
A. The students tend to have fewer siblings than the teachers.
Step-by-step explanation:
First we need to draw the dot plots correctly. If you count both sides they have 20 each.
Now, clearly none have fewer nobody here yet has more or less but going on to the next step.
Multiply exactly the number of siblings times how many people chose that many siblings. Ex: 2 (siblings) times 7 (people who has 2 siblings) = 14. And so on.
On the Student A, we get a total of 41 people having sibling, if you count the 0's then there were a total of 43 people. But now on the Teacher's A Dot Plot, we have a total of 68 people, if you include the 0 then we have a total of 69.
So the answer is A. The students tend to have fewer siblings than the teachers.
Let vanessa's height = v.
twice of vanessa's height = 2v
64 decreased by... = 64 -
64 - 2v is your algebraic expression
hope this helps
8g+10=35+3g You need to find what number g is, just plug in random numbers till both sides are equal
Answer:
Step-by-step explanation:
Let's FOIL this out and get it into standard quadratic format:
. The lack of a linear term in the middle means therewas no upwards velocity, consistent with the object being dropped straight down as opposed to thrown up in the air tand then falling in a parabolic path. The -4.9t² represents the acceleration due to gravity, and the 490 represents the height from which the object was dropped. The constant in a quadratic that is modeling parabolic motion always represents the height from which the object was dropped (or launched). That's how you know.
