It takes you 1/4 hours to walk 1/3 of a mile.
How long will it take you to walk 2 1/2? Miles?
PLS HELP ASAP

Answers

Answer:

15/8 Hours

Step-by-step explanation:

To start, I would find see how long it takes to walk a mile.

1/3 · 3 = 1

1/4 · 3 = 3/4

So we now know that walking one mile takes 45 minutes. Next, I multiplied 1 mile by 2.5 and repeated the same process with the time.

3/4 · 5/2 = 15/8

Therefore, it takes 15/8 hours to walk 2.5 miles.

Answer:

[tex]\underline{\boxed{\sf -38}}[/tex]

Step-by-step explanation:

[tex]\sf 35+(-1)+(-64)+(-8)[/tex]

Subtract 1 from 35= 34

[tex]\sf 34-64-8[/tex]

Subtract 64 - 34= -30

[tex]\sf -30-8[/tex]

Subtract 8 - 30 = -38

[tex]\sf -38[/tex] ← Answer

Answer: 90

Steps:

Step 1.
Group the positive and negative terms in 35 + (-1) + (64) + (- 8) together and factor out the minus sign. Also remove the parenthesis.

Step 2.
35 - 1 + 64 - 8
(35 + 64) - (1 + 8)

Step 3.
Evaluate 35 + 64.
35 + 64 = 99

Therefore we have 99 - (1 + 8)

Step 4.
Evaluate 1 + 8.
1 + 8 = 9

Therefore we have 99 - 9.

Step 5.
Subtract 9 from 99.
99 - 9 = 90

what are rational. numbers?

Answers

Rational numbers are numbers that can be expressed as a quotient or fraction, written in p\q form, where q cannot equal 0. Example would be 2/5, 1/3, 9/3.
Answer:

Rational numbers are defined as "a number that can be expressed as the quotient or fraction p/q of two integers, a numerator p and a non-zero denominator q." This quote can be broken down to make it easier to understand. In basic terms, a rational number is a real number that is an integer, fraction, terminating decimal, or repeating decimal.

Integer

An integer is any positive or negative whole number including 0. Examples of integers include 4, -9, and 0.

Fraction

All fractions that do not have a 0 denominator (which makes the number undefined) are rational numbers. Additionally, complex fractions are not always considered rational numbers. Complex fractions are fractions where either the numerator or denominator is a decimal or fraction itself. Examples of rational fractions include [tex]\frac{4}5}[/tex], [tex]\frac{7}{4}[/tex], and [tex]\frac{2}{2}[/tex].

Terminating Decimals

Terminating decimals are decimals that have a finite number of digits. This means that the decimal stops at some point. Examples of terminating decimals include 0.346, 0.47834, and 0.345832454525456

Repeating Decimals

Repeating decimals are any decimal that is not terminating but has some pattern that repeats for infinity. Examples of repeating decimals include [tex]0.\bar 9[/tex], [tex]0.\bar8\bar6[/tex], and [tex]0.\bar 5\bar7\bar8\bar4[/tex]. In this case, the bar notation represents numbers that repeat forever.

The short sides of a rectangle are 2 inches. The long sides of the same rectangle are three less than a certain number of inches.

Suppose that you are given the value of the unknown number. Verbally describe two methods for finding the area of this rectangle. Use complete sentences in your answer.

PLS HELP

Answers

1) You use the formula for finding area of rectangle which is the multiplication of width and height. You multiple 2 and x-3.

2) Another method can be dividing the rectangle into 2 triangles (draw a line from one corner to opposing corner) and finding the areas of each triangle. Area of triangle is 1/2 base* height so 2 triangles makes it base * height which is same formula as previous one.

Answers

Answer:

The cost of pet carrier = $21.89

The cost of 1 bag of cat food = $16.46

The cost of 2 bags of cat food = $16.46 × 2

Use the distributive property and then simplify the expression.

3(x-8)+6(x+4)

Answers

9x-12 is the answer I believe
Hello!

Answer: 9x

Explanation: Distributive property basically multiplies the numbers inside the parentheses by the number outside of them.

So, in this case, to simplify both parts of the equation, you’d have to multiply “x” and “8”by 3, and the other “x” and “4” would be multiplied by 6.

3 times “x” would be 3x, and 3 times “-8” would be -24. So the first part simplified would be: -24+3x.

Now for the second part, 6(x+4). We’d multiply “x” and “4” by 6. This would get us 6x and 24.

Now to simplify. We currently have the expression “(-24+3x)+(6x+24)”.
As -24 and 24 cancel each other out, the only things we would have left to simplify would be 3x+6x.
3x+6x is equal to 9x.

So there’s how you’d get your answer of 9x!

Hopefully this was explained easy enough for you! If not, please comment!

I hope this helps you! :)
