Answer:

c = -2

Step-by-step explanation:

-5c - 10 - 5c - 2 = 8

-10c - 12 = 8

      +12     +12

-10c = 20

/ -10    / -10

c = -2

Answer:

he went 13 units right instead of 12

Step-by-step explanation:

Answer:

A = (-2 , -1)                 A’ = (-5 , -1)

B = (2 , -1)                  B’ = (-1 , -1)

C = (2, 2)                   C’ = (-1 , 2)

Answer:

Step-by-step explanation:

If you know the radius of the circle, double it to get the diameter. The radius is the distance from the center of the circle to its edge. If the radius of the circle is 4 cm, then the diameter of the circle is 4 cm x 2, or 8 cm. If you know the circumference of the circle, divide it by π to get the diameter

there’s 2 basic cases you’ll see to find the diameter (a line that basically cuts the circle in half)

you’ll either be given the radius (the distance between the center of the circle to any point on the circle) or the circumference (the perimeter of the circle)

so you have two equations:

diameter= 2*radius

circumference= diameter * pi

if they gave you the radius, simply multiply by 2 as the first equation states. if they give you the circumference, divide the circumference by pi (which is approx. 3.14)

Mathematics includes the study of such topics as quantity, structure, space, and change. It has no generally accepted definition. Mathematicians seek and use patterns to formulate new conjectures; they resolve the truth or falsity of such by mathematical proof.

Step-by-step explanation:

Mathematics is the study of numbers, shapes and patterns. The word comes from the Greek word "μάθημα" (máthema), meaning "science, knowledge, or learning", and is sometimes shortened to maths (in England, Australia, Ireland, and New Zealand) or math (in the United States and Canada). ... Numbers: how things can be counted.

Therefore, Mathematics is the abstract study of topics such as quantity (numbers), structure, space, and change!

Answer:

x + 14 = 5x - 74

x - 5x = -4x

-74 - 14 = -88

-4x = -88

-4x/4 = -88/-4

x = 22

Answer: -8r+12

Step-by-step explanation:

============================================

Explanation:

The outer term -2 is multiplied by each term inside

Then those results are added to get -8r + 12 as our final answer. We cannot combine these terms because they are not like terms.

I used the distribution property, also known as the distributive property.

That says a*(b-c) = a*b - a*c

In this case, a = -2, b = 4r, and c = 6.

Step-by-step explanation:

The boys have $16 on 11th day.

The graph is simply a structured representation of the data. It aids in our comprehension of the data. The numerical information gathered through observation is referred to as data.

Following the creation of a research question, data is continuously gathered through observation. The information is subsequently arranged, condensed, categorised, and visually portrayed.

In a line graph, the information or data is represented as a series of markers, or dots, and is then connected to one another by a straight line.

Usually, data that varies over time is represented with a line graph.

Given:

Daryll is given $30 and spends $1.25 per day on basketball cards.

Larry is given $2 and saves $1.25 per day.

So, to find the same day for both from the graph.

We have to focus on where the lines for two persons intersects, it will the on same day how much money they have.

Hence, the boys have $16 on 11th day.

Hey did u hear about Gavin Magnus and Piper Rockelle

Answer:

the answer is C because according to the graph, the y-intercept is -6 and the slope is 3.

slope is rise over run, so find a point thats directly on a corner of the grid (i chose the y-intercept) and then count to see how many lines are between that point and the next one that's directly on the lines. (it's (1, -3)) making the slope 3/1 or 3
