The slope is 1/2 and the Y intercept is -3, so the equation will be Y=1/2x-3

Answer:

y = ½x - 3

Step-by-step explanation:

The question is asking for the line to be formatted in the y = mx + b format.

m is the slope of the lineb is the y intercept

For this question, the slope is 1/2, for every 1 unit the line goes up (rise), it goes 2 units forward (run). The y intercept is -3, hence the equation of the line is y = ½x - 3.

Find the length of the hypotenuse in the triangle below

Answers

Answer:

The hypotenuse is 15. Please give Brainilest

Step-by-step explanation:

Since it is a right triangle, it probably follows the Pythagorean theorem

basically saying two legs squared equal hypotenuse squared

[tex]a^2+b^2=c^2[/tex]

In this case, if you know your Pythagorean theorem triples, then the

answer will be 9,12,15

If you don't let me explain

[tex]9^2 = 81\\12^2 = 144\\15^2=225\\\\a^2+b^2=c^2\\9^2+12^2=15^2\\81+144=225\\[/tex]

This is correct

If you don't know how I got this, learn the first five or six Pythagorean theorem triples, and these will be a piece of cake for you. Remember this only works for right triangle though.

Tess and Dan have $24.00 each to spend at a book fair, where all students receive a 15% discount. They both want to purchase a copy of the same book, which normally sells for $24.50 plus 10% sales tax. To check if she has enough to purchase the book, Tess takes 15% of $24.50 and subtracts that amount from the normal price. She takes 10% of the discounted selling price and adds it back to find the purchase amount. Dan takes 85% of the normal purchase price and then computes 110% of the reduced price. Is Tess correct? Is Dan correct? Do they have enough money to purchase the book? Explain your answer using complete sentences, and show your work.

4 3/5 + 5 1/2
Help me please and thank you

Answers

Answer:

Step-by-step explanation:

4 3/5 + 5 1/2= (10 1/10)

Step 1: Find the common multiple between the numbers, and simplify-

4 3/5=4 6/10 5 1/2= 5 5/10

Step 2: Convert to improper fractions-

4 6/10 as an improper fraction is 46/10 and 5 5/10 as an improper fraction is 55/10 (Formula for mixed numbers to improper fractions is denominator multiplied by whole number plus numerator)

Step 3: Add numerator of improper fractions, then add back denominator-

46+55=10 1 numerator:101 denominator:10 101/10

Step 4: Convert into mixed number-

101/10= 10 1/10

ANSWER: 10 1/10

Answer:

10.1

Step-by-step explanation:

Conversion a mixed number 4 3/

to a improper fraction: 4 3/5 = 4 3/

= 4 · 5 + 3/

= 20 + 3/

= 23/

To find a new numerator:

a) Multiply the whole number 4 by the denominator 5. Whole number 4 equally 4 * 5/

= 20/

b) Add the answer from previous step 20 to the numerator 3. New numerator is 20 + 3 = 23

c) Write a previous answer (new numerator 23) over the denominator 5.

Four and three fifths is twenty-three fifths

Conversion a mixed number 5 1/

to a improper fraction: 5 1/2 = 5 1/

= 5 · 2 + 1/

= 10 + 1/

= 11/

To find a new numerator:

a) Multiply the whole number 5 by the denominator 2. Whole number 5 equally 5 * 2/

= 10/

b) Add the answer from previous step 10 to the numerator 1. New numerator is 10 + 1 = 11

c) Write a previous answer (new numerator 11) over the denominator 2.

Five and one half is eleven halfs

Add: 23/

+ 11/

= 23 · 2/

5 · 2

+ 11 · 5/

2 · 5

= 46/

+ 55/

= 46 + 55/

= 10.1

An orchard sells apples in 5.5‐pound bags. The orchard sells 65 bags of apples each day.

How many pounds of apples does the orchard sell in 1 week?

The orchard sells
pounds in 1 week.

Answers

Answer:

2502.5 pounds

Step-by-step explanation:

Answer:

2,503 pounds

Step-by-step explanation:

Multiply the amount of bags sold by the number of days within a week.

65 x 7 = 455

In 1 week 455 bags of apples are sold.

The next step is to multiply the total amount of bags sold in 1 week by the pound of 1 bag of apples.

455 x 5.5 = 2,502.5lbs

2,503lbs (rounding to the nearest whole number) of apples are sold in 1 week.

Someone please help. Explain why it might be easier to solve the multiplication problem by changing it from this: 5×98×2 , to this: 5×2×98 . Use a property of multiplication to justify your reasoning.

Answers

Answer:

Because it is easy to multiply 5 by 2 which is 10......and then 10 × 98 youbjust have to add 0 to 98.....which will be 980

The multiplication problem can be simplified by the equation A = 5 x 2 x 98 and the value of A = 980

What is an Equation?

Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.

It demonstrates the equality of the relationship between the expressions printed on the left and right sides.

Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.

Given data ,

Let the equation be represented as A

Now , the value of A is

Substituting the values in the equation , we get

A = 5 x 98 x 2

On simplifying , we get

From the associative property , we get

A = ( 5 x 2 ) x 98

where the value of 5 x 2 = 10

So , the multiplication expression is

A = 10 x 98

A = 980

Therefore , the value of A is 980

Hence , the equation is A = 980
