If Eli ate one third of a pie on friday ,one fourth proportion of the pie on saturday and 50 ounces of the pie on sunday then it is found that she ate 30 ounces of pie.
Given that Eli ate one third of a pie on friday, one fourth of the pie on saturday, and final 50 ounces of the pie on sunday which is left out.
We have to find the amount of pie that she ate one saturday.
We are given fraction and we know that sum of all fractions of something is equal to 1.
Let the proportion that she ate on sunday be x.
1/3+1/4+x=1
Taking LCM.
(4+3+12x)/12=1
7+12x=12
12x=12-7
12x=5
x=5/12
So the left out out portion that she ate on sunday is 5/12 of the pie.
We are given that she ate 50 ounces on sunday so the total pie will be 12/5*50=120 ounces.
Portion eaten by Eli on saturday =1/4
Pie that she ate on saturday=1/4*120
=30 ounces.
Hence Eli ate 30 ounces of pie on saturday.

Which expression is equivalent to 1/2b -15?
A. -1/2 (b + 30)
B. -1/2 (b - 30)
C. 1/2 (b - 30)
D. 1/2 (b + 30)
The expression 1/2b -15 is equivalent to, 1/2(b-30), So option C is correct
What are expressions?An expression is a sentence with at least two numbers or variables having mathematical operation. Math operations can be addition, subtraction, multiplication, division.
For example, 2x+3
Given that,
An expression, 1/2b -15
The expressions are equivalent = ?
So now, we can take 1/2 common from the expressions
⇒ 1/2b -15(2/2)
⇒ 1/2(b -15×2)
⇒ 1/2(b - 30)
Hence, the equivalent expression is, 1/2(b - 30)

4. What is the axis of symmetry for h(x) = 19(x – 5)^2 + 6
Answer:
x = 5
Step-by-step explanation:
The equation of a parabola in vertex form is
y = a(x - h)² + k
(h, k ) are the coordinates of the vertex and a is a multiplier
h(x) = 19(x - 5)² + 6 ← is in vertex form
with vertex (h, k ) = (5, 6 )
The axis of symmetry is a vertical line passing through the vertex
with equation x = 5

solve this system of equations by using the elimination method.
2x-3y=25
5x+3y=10
Elimination method is my favorite way to solve 2 equations like this written in standard form! First I'm going to rewrite the equations and mark numbers to make this explanation more clear.
2x-3y=251️⃣
5x+3y=102️⃣
Looking at these 2 equations we can see that there is a +3 and a -3. This could be eliminated by adding the 2 equations together! *Remember what is on the left side adds with the left side, and what's on the right side adds with the right side. Therefore we can do:
1️⃣+2️⃣
2x-3y+5x+3y=25+10
7x=35
x=5
Then we can substitute the value of x back into either of the 2 equations.
2*5-3y=25
10-3y=25
3y=-15
y=-5
Then write the 2 answers together.
{x=5
{
{y=-5
Now we can check our answers.
2*5-3*-5=10- -15= 10+15=25 Correct
5*5+3*-5= 25+ -15= 10 Correct
From this we can see that x=5 y= - 5 are the correct answers!

Diane looked out the window in the store parking lot and said, “There are 13 motorcycles and cars in the lot.” Steve looked out the window and said, “I see 42 wheels.”
Question: How many motorcycles and how many cars are in the parking lot?
Answer:
There are 5 motorcycles and 8 cars in the parking lot.
Step-by-step explanation:
Set variables X to represent the number of cars and Y to represent the number of motorcycles. You will get the following equations:
X + Y = 13 (Total number of motorcycles and cars)
4X + 2Y = 42 (Total number of wheels)
Combine the two equations together and solve for Y and X
4(13 - Y) + 2Y = 42 note: X = 13 - Y
52 - 4Y + 2Y = 42
-2Y = -10
Y = 5
X + 5 = 13
X = 8

Part A: If PM =PN and MPQ=UNPQ which triangle congruency postulate can we
use to determine APMQ = APNQ given the information on the figure?
OSAS
O SSS
O AAS
O ASA
Part b:How did you determine your answer in part A/Question 2?
Answer:the answer for part A is SAS.
Step-by-step explanation:
We already know that side PQ is the same length for both the triangles. We were then given the information that sides PM and PN were equal. So now we already have two sides that are the same. Then we were given the information that angle MPQ and angle NPQ were also equal. So now we have two sides and an angle that are equal. This is how we got SAS (side angle side). I tried my best to explain. I added a photo so you could see what I was trying to explain. Hopefully this helped!
