Given the values that we have here for the large sizes and the family size of cereal the one that has the lowest price per ounce is that of the Large size at $0.21 per ounce
How to solve for the sizes of the cerealsFor the family size
We would first have to divide 5.34 by 24
= 5.34 / 24
= 0.22 per dollar
For the large size we have
15 ounces for $3.14
= 3.14 / 15
= 0.21 dollars
Hence we can see that the size of the cereal that is the lowest price per ounce is given as Large size at $0.21 per ounce

Step-by-step explanation:
2 things to remember :
the sum of all angles in a triangle is ashtrays 180°.
the sum of all angles around a point on one side of a line is also always 180° (because that represents a half-circle).
let's call the 3rd angle in the triangle "innerQ".
so,
180 = (4x + 13) + 19 + innerQ
180 = (7x + 2) + innerQ
as innerQ is also the supplementary angle of 7x + 2.
because of that, we can now say
(4x + 13) + 19 + innerQ = (7x + 2) + innerQ
4x + 13 + 19 = 7x + 2
4x + 32 = 7x + 2
30 = 3x
x = 10
so, the angle S = 4×10 + 13 = 40 + 13 = 53°

In an inverse variation,y = 4when x = 2.Write an inverse variatione quation thats hows there relationship between x and y . Write the equation using a decimal or an integer.
When y = 4 and x = 2, the inverse variation equation is y = 8/x
What is inverse variation?Inverse variation is variation in which the relationship between two variables is an inverse one. That is, while one variable increases, the other decreases.
How to write an inverse variation equation that shows there relationship between x and y.Given that in an inverse variation, y = 4 when x = 2. Since y and x have an inverse relationship, we have that
y ∝ 1/x, this implies that
⇒ y = k/x where k = constant of proportionality
Now, given that in an inverse variation, y = 4 when x = 2. Substituting the values of y and x into the equation, we have that
y = k/x
4 = k/2
k = 4 × 2
k = 8
So, susbstituting k = 8 into the equation for y, we have
y = k/x
y = 8/x
So, the inverse variation equation is y = 8/x

Write an equation to represent this relationship.
The relation between these two variables can be represented by the linear equation:
y = 4ft + 2.5ft*x
How to write an equation that represents this relationship?We know that the original height of the tree was 4 ft, and it grows 2.5 feet each year.

According to the statement
We have to find that the value of the linear equation.
So, For this purpose, we know that the
The definition of a linear equation is an algebraic equation in which each term has an exponent of one and the graphing of the equation results in a straight line.
From the given information:
It is given that:
The equation shown includes a missing value.
-2(2x - ?) + 1 = 17 - 4x
Applying the distributive property:
-4x + ? + 1 = 17 - 4x
? + 1 = 17
There aren't any values that the equation has only 1 solution or unique solutions.
For no solution the missing value are often anything except 16
? + 1 = 17
? = 17 - 1

change in weight of Callie's cat?
The total change in the weight of Callie's cat will be - 1 5/8 pounds.
Callie's cat lost weight = 4 1/2 pounds
Lost = 9 / 2 pounds
Cat gained the weight = 2 7/8 pounds
Gained = 23 / 8 pounds
Net change = - 9 / 2 pounds + 23 / 8 pounds
= - 36 / 8 pounds + 23 / 8 pounds
= - 13 / 8 pounds

prove that triangles abc and def are congruent
Answer:
Below.
Step-by-step explanation:
In Δ ABC m < B = 180 - (50+70) = 60 degrees.
in Δ DEF m < D = 180- ( 60 + 70) = 50 degrees.
BC = DE ( both are 10 cm).
m < A = m < F ( both 70 and directly opposite BC and DE)
m < C = m < D (corresponding angles and both = 50 degree)
Therefore, Δ's ABC and DEF are congruent by AAS.
