What is an expression?

The mathematical expression combines 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 denote the logical syntax's operation order and other properties.

Given that 0.9 is the result of finding the product of 2 and 3/4 minus a number.

The unknown number will be calculated as,

( 2 x 3) / 4 - N = 0.9

N = (3 / 2) - ( 9/10)

N = ( 15 - 9 ) / 10

N = 6 / 10

N = 3 / 5

Therefore, the unknown number will be equal to 3 / 5. The correct option is C.

What additional information is required to prove the triangles are congruent using ASA?
Since vertical angles are congruent assume:

Answers

Answer:

C

Step-by-step explanation:

We already have one angle form the question that leaves us with one other angle and one side that we need to find, since we are required to use ASA or angle-side-angle.

the diagram gives us 2 congruent sides UB and AB since they have a similar slash on both of them, finally we need one more angle, so we look at the choices we have:

a) it gives us congruent sides not angles, so we move to the next

b) same thing as A

c) gives us 2 congruent angles, and since these are 2 new angles not given in the question, they can work

d) these 2 angels are the same 2 given in the question, so we can't use them.

Lynn put 3 7/8 gallons of gas in her gas tank. If there are now 18 1/6 gallons in the tank, how many gallons did she start with?
x - gallons she started with

Answers

Answer:

14.3 gallons      = 4 + 7.25/25  or 14.29 gallons.

Explanation:

18 1/6 gallons - 3 7/8 = 14.29

18 - 3 = 15

1/6 - 7/8 = 15 - 0.70833333333 = 14.2916666667

You need to be careful here if you use basic subtraction, simply as two minus would change to addition.

First change the mixed number of gallons into improper fractions.

3 7/8 ——> 31/8
18 1/6 ——> 109/6

Then find the LCM ( Lowest Common Multiple) in this case of the denominators it would be 24.

Convert both fractions as a factor of 24;

31/8 ——> 93/24
109/6 ——> 436/24

Then you want to take away the amount she was left with from how many she had added;

436 93 343
——— minus ——— = ———
24 24 24


As a mixed number this could be written

7

What is the y-intercept of a line that has a slope of -3 and passes through point (-5, 4)? a) -17 b) -11 c) 7 d) 19​

Answers

Answer:

(- 11)

Answer b is correct

Step-by-step explanation:

To find this you can use

y = mx + c

Here,

m = slope

c = y - intercept

( -5, 4) = ( x ,y)

Let us solve now .

[tex]y = mx + c[/tex]

[tex]4 = - 3 \times - 5 + c \\ 4 = 15 + c \\ 4 - 15 = c \\ - 11 = c[/tex]

Therefore,

c = (-11)

That means y - intercept is ( -11 )

Answer:

Given : points 4  , 1 ,25  , opposite of 3 ,  -1/2

To Find : draw on Number Line

Solution :

Numbers with a negative sign are less than zero

Right of zero represented by ‘+’ sign and to the left of zero represented by ‘–’ sign.

+ sign numbers can be denoted as simply numbers  

On a number line the number increases as we move to the right and decreases as we move to the left.  

1 : Draw a line and mark some points at equal distance on it as shown in the figure below  Mark a point as zero on it. Points to the right of zero are positive integers and are marked simply 1, 2, 3  and so on , while points to the left of zero are negative integers and are marked – 1, – 2, – 3 and so on

2.  Go 4 unit on right sides from Zero   to show  4

3.  Go 3 units on Left from zero to show opposite of 3

4.  Divide number line between 1 & 2 in 4 Equal parts and go 1 part right of 1
