Mary has a container filled with 20 ounces of cereal. Each day she eats 4.5 ounces
of cereal.
• Write an expression to represent the amount of cereal left after x days.

Answer:

what are we supposed to find here ?

Answer:

The two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Step-by-step explanation:

If the starting of both the equation is from "Y=" then it means that whatever equation (having x variable) they are representing will be equal to each other as both the equation on one side are ultimately equal to Y

For example

Y = 3X + 5 ---- Eq (1)

Y = 7X +6  ---- Eq (2)

So both are equal

3X + 5 = 7X + 6

4X + 1 = 0

In this way the two equations (representing value of variable Y) can be equated and converted into one single equation with X variable only

Answer: A+P=11,    0.60A+0.35P=5.60

Answer:

3 pounds 2 oz

Step-by-step explanation:

1 pound = 16 oz

x pounds = 50 oz

Cross Multiply

16x = 50 oz             Divide by 16

x = 50 / 16

x = 3 pounds with 2 oz left over.

Your calculator will give you 3.125

0.125 = 1/ 8

1/8 * 16 = 2

Step-by-step explanation:

Given

f(x) = - x² - 9x - 7

f(3) = -( 3) ² - 9 * 3 - 7

= - 9 - 27 - 7

= -43

Congruent triangles have equal corresponding sides lengths and angles

Another valid congruency statement is Triangle RYQ ≅ Triangle LSJ

The congruency statement is given as:

Triangle QRY ≅ Triangle JLS

The above means that triangles QRY and JLS are congruent,

So we have the following congruent points

Points Q and J

Points R and L

Points Y and S

So, another valid congruency statement is Triangle RYQ ≅ Triangle LSJ

Answer:

Step-by-step explanation:

Your graph equation is going to be y = 100,000 - .06x

The formula for slope is vertical change ÷ horizontal change, which means choose two points, (x1,y1) and (x2,y2), then do (y2-y1) ÷ (x2-x1).

For the graph, just pick two random points that you like. For the table, pick two sets of numbers (for example -10,-47 and 4,9). For the equation, create two sets of coordinates. For example, if you have f(x) = x + 3, then if x = 1, y = 4 and if x = 2, y = 5.

Answer:

x = 4

Step-by-step explanation:

the given figure is of an isoceles triangle.

The two angles opposite are congruent(i.e78 degrees) .

That is the sides opposite to them are also congruent.

I. e 4x + 23 = 10x - 1

I. e 4x - 10x = -1 -23

I. e -6x = -24

I. e -x. = -24/6

Dividing by 6 to 24 we get,

-x = -4

therefore by removing the minus sign from both the sides,

the answer comes x = 4

Answer:

6 companies.

Step-by-step explanation:

[When you read a stem and leaf plot, the lowest number in the stem category, like 3 for example, would be in the tens place. The numbers in the leaf category are the ones places.]

"At least" tells you that anything equal to or higher the number given is relevant to the question. If we count the amount of numbers that are 63 or over, we have:

63, 69, 70, 73, 76, 78.

These are 6 numbers.

Your answer would be 6 companies.

Answer:

362.35N/m²

Step-by-step explanation:

Pressure = Force/Area

Area = πr²

Area = 3.14(0.75)²

Area = 3.14(0.5625)

Area = 1.76625m²

Force = 640N

Pressure = 640/1.76625

Pressure = 362.35N/m²

Step-by-step explanation:

2.8/100 × 3827 = $107.16

monthly = 1/12

[tex]p = \frac{100 \times i}{rt} = \frac{100 \times 107.16}{2.8 \times \frac{1}{12} } = \frac{10716}{0.23} \\ = 46591.3[/tex]

Answer:

x=-1

y=15

Step-by-step explanation:

This works because completing the square is essentially demonstrating what g(x)  - where g(x) in this case = x^2 - would have to be translated by to give the function you have.

So by completing the square you have shown that the function you've been given has been shifted to the left by -1, stretched by a factor of 2 along the y axis and shifted up by 15.

Answer: She has enough.

Step-by-step explanation:

You need to add up the quantities of water needed first. That will then tell if she has enough water.

Convert the fractions to decimals then add them up:

3/8 = 0.375

1/4 = 0.25

= 0.25 + 0.375

= 0.625 cups of water is required.

This is less than the 1 cup she has so she has enough water to make the snack.

Answer:

The answer is 10.

Step-by-step explanation:

2/3 times 15 is the same as 2/3 of 15.

2/3 of 15 is 10.

So, the answer is 10.
