Define a variable, set up an equation, then solve.
The sum of two numbers is 91. The smaller number is thirteen less than the larger number. Find both numbers.
x - large number
y - small number

Answers

Answer 1

Answer:

x=52 and y=39

Step-by-step explanation:

52 + 39 = 91

52 - 13 = 39

Answer 2

What you would do is make the equation:

91=X+(X-13)

Then, you would solve for X and once you find X, you would subtract 13 from it.

The answers should be 52 and 39.

Define a variable, set up an equation, then solve.
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
as 14 —-
24

Find
y
'
and then find the slope of the tangent line at
(
2
,
225
)
. Round the slope and y-intercept to 3 decimal place.

Answers

Since we are given the point, all we need to find is the slope to discover the tangent line.
To find the slope, you plug in 2 for y’ as it is the x-value of the point.

y’ = 2((2)^2+2(2)+7)(2(2)+2) = 180

Plug in the point and the slope in the point-slope formula

y - y1 = m(x - x1)

y - 225 = 180(x - 2)

Solve for y

y = 180x - 360 + 225

y = 180x - 135

Please be sure to describe on which tick marks each point is plotted and how many tick marks are between each integer. It may help for you to draw this number line by hand on a sheet of paper first. brainleist for right answere if u dont answer propoly i will report!

Answers

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

5.  Divide number line between  0 & -1  in 2 Equal parts and go 1 part left of 0

Solve for x.
4 (x + 1 1/3) = 9 2/3
Enter your answer as a mixed number in simplest form.

Answers

Answer:

x = 13/12

x = 1 1/12

Step-by-step:

4 (x + 1 1/3) = 9 2/3

4x + 5 1/3 = 9 2/3

subtract 5 1/3 from each side

4x = 4 1/3

divided by 4 on each side

x = 13/12

x = 1 1/2

X = 1 1/4

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 )

At the end of the season, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount. What is the sale price of the bat?

Answers

Discount=35%

35% of 347.250.35(347.25)121.54

Sale price

347.25-121.54$225.7

The sale price of the bat will be;

⇒ $225.71

What is mean by Percentage?

A number or ratio that can be expressed as a fraction of 100 or a relative value indicating hundredth part of any quantity is called percentage.

Given that;

Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% disount.

Now,

Since, Karl buys a discounted baseball bat that normally costs $347.25 using a coupon for a 35% discount.

Hence, The discount price = 35% of $347.25

                                          = 35/100 × $347.25

                                          = $121.54

Thus, The sale price = $347.25 - $121.54

                                = $225.71
