The temperature Saturday is -13°, and on Sunday it is -4°. Which equation would be used to show the difference in temperature from Saturday to Sunday?
-4 + 13 =
-4 - (-13) =
-4 - 13
4 + (-13)

Answers

Answer 1
-4 - (-13) = 9 is the answer
Answer 2

to change the temperature from -13 on Saturday to -4 on Sunday, you would need to add 9 degrees ( -13 + 9 = -4 )

 so you need the equation that would also = 9

-4 + 13 = 9

-4 - (-13) = 9

-4 -13 = -17

4 +(-13)= -9


 there are 2 equations that equal the correct change in temperature, but since both temperatures are negative ( -13 & -4)

 the correct equation would also contain 2 negative numbers

 so correct equation should be: -4-(-13) =

What is another way to write the expression ​ r⋅(18−3) ​?



(r⋅18)−(r⋅3)

r⋅18−3

(r⋅18)⋅3

(r⋅18)−3

Answers

i believe the first one would work

The other way to write the expression ​ r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.

What is an expression?

It is defined as the combination of constants and variables with mathematical operators.

It is given that the expression is, r⋅(18−3)

We have to expand the expression in order to write the expression in the other way,

The expanding form can be used to indicate the value of each digit in a number in arithmetic. Numbers that are expressed as the sum of each digit multiplied by its place value are known as expanded numbers.

There are the different identity used in the expanded form as,Use the following identity as

a(b-c) = ab-ac

=r⋅(18−3)

=(r⋅18)−(r⋅3)

Thus, the other way to write the expression ​ r⋅(18−3) will be (r⋅18)−(r⋅3). Option A is correct.

Jack owed $12.00 in library fines.half of this was for 2 overdue videos.the rest was for 6 books that were each 20 days overdue how much did jack owe for each overdue book

Answers

1$ would be the answer. Because if half of the 12 dollar fines would be 6$. And then in order for the 6 books to equal out evenly it would have to be 1$
Jack owes $1.00 for each book. $12.00 ÷ 2 = $6. $6 ÷ 6 = 1. So your answer is $1.00.

What is an expression?

The mathematical expression is the combination of numerical variables and operations denoted by addition, subtraction, multiplication, and division signs.

Mathematical symbols can be used to represent numbers (constants), variables, operations, functions, brackets, punctuation, and grouping. They can also be used to denote the logical syntax's operation order and other properties.

Given that Keith buys a bag of dog food. The bag contains 16¹/₂ cups of food. If his dog eats 1³/₈ cups a day,

The time will be calculated as:-

T = ( 16¹/₂ ÷ 1³/₈ )

T = ( 16.5 ÷ 1.375 )

T = 12 days

Therefore, the number of days required to feed dog food will be 12.

Four friends purchase 18.4 pounds of peaches. The peaches cost $1.75 per pound. The friends share the cost of the peaches equally. How do I do this!!!!?????????

Answers

You take the cost 18.4 multiply by 1.75 to find out the total cost of the peaches then divide by 4 to split the cast and you answer should be roughly 8

Answer:

Cost per friend = 8.05 $

Step-by-step explanation:

Four friends purchase 18.4 pounds of peaches.

The peaches cost $1.75 per pound.

Total cost of peach = Total pounds x Cost of peach per pound

Total cost of peach = 18.4 x 1.75 = 32.2 $

Number of friends dividing the cost equally = 4

[tex]\texttt{Cost per friend = }\frac{\texttt{Total cost of peach}}{\texttt{Number of friends dividing the cost equally}}\\\\\texttt{Cost per friend = }\frac{32.2}{4}=8.05\$[/tex]

Cost per friend = 8.05 $

I suck a writing proofs in geometry.... please someone explain it to me, i cant seem to reconize what's going on. I need major help in properties of congruent proofs.

Answers

Congruence Properties

In earlier mathematics courses, you have learned concepts like the commutative or associative properties. These concepts help you solve many types of mathematics problems. There are a few properties relating to congruence that will help you solve geometry problems as well. These are especially useful in two-column proofs, which you will learn later in this lesson!

The Reflexive Property of Congruence

The reflexive property of congruence states that any shape is congruent to itself. This may seem obvious, but in a geometric proof, you need to identify every possibility to help you solve a problem. If two triangles share a line segment, you can prove congruence by the reflexive property.

line segment
perpendicular lines
parallel lines
ray

Answers

The correct answer is:

parallel lines  

Explanation:

Parallel lines are two lines in a plane that never intersect.  This means the definition uses the undefined terms "line" and "plane."

The undefined terms line and plane are needed to precisely define which mathematical term will be parallel lines so option (C) will be correct.

What are a line and plane?

A line section that can connect two places is referred to as a segment.

In other words, a line segment is just part of a big line that is straight and going unlimited in both directions.

A plane is a surface that is straight in nature a plane has a certain area but in most cases.

We know that parallel line are those lines which not intersect and lies on a plane.

Hence there are two things that are needed first is a line and the second is a plane the plane should be single for both lines not different.
