Bob and Cheryl are taking a road trip that is 188.3 miles. Bob drove 5/7 of the totalDistance. How many miles did Bob drive?

Answers

Answer 1

Answer:

the total distance of the road trip is 188.3 miles

Both Bob and Cheryl took turns and drove

Bob has driven 5/7th of the total distance

distance Bob has driven - $(5)/(7)of188.3miles$

when the 'of' function is used we have to multiply

$(5)/(7)*188.3 = (5*188.3)/(7) = 134.5$

therefore distance Bob drove is 134.5 miles

Answer 2

Answer: $x-\ distance\ drove\ by\ Bob\n\ny-\ distance\ drove\ by\ Cheryl\n\nx=(5)/(7)*188,3\ny=188,3-x=188,3-(5)/(7)*188,3=(2)/(7)*188,3\n\ny=53,8\ miles\n\nx=134,5\ miles\n\nBob\ drove\ 134,5\ miles.$

Answers

$\sf(3)/(5)(3y+15)$

Distribute 3/5:

$\sf(3)/(5)*3\rightarrow(3*3)/(5)\rightarrow(9)/(5)$

$\sf(3)/(5)*15\rightarrow(3*15)/(5)\rightarrow(45)/(5)\rightarrow9$

So we have:

$\boxed{\sf(9)/(5)y+9}$

Explain how to break apart the addends to find the sum 25+16

Answers

(20+5)+(10+6)
you are supposed to use place value to break it down

Final answer:

To find the sum of 25+16 by breaking apart addends, you can break the numbers into tens and ones. Adding the separate tens and ones gives 30 and 11 respectively. Adding these results together, the final sum is 41.

Explanation:

The subject of your question is a fundamental mathematical concept known as addition. Specifically, you have asked to explain how to break apart the addends to find the sum of 25+16.

When we talk about 'breaking apart addends', we're referring to the strategy of making it easier to compute a big addition problem by breaking the numbers into more manageable pieces. You can usually do this by breaking numbers down into tens and ones. This is also known as 'use place value' in numerical operations.

Let's break the operation down: 25 + 16.

First, identify the tens and ones in each addend - 25 is made up of 2 tens (20) and 5 ones, and 16 is made up of 1 ten (10) and 6 ones.
Second, add together the tens, then add together the ones. You get 2 tens (from 25) + 1 ten (from 16) = 30, then add 5 ones (from 25) + 6 ones (from 16) = 11.
Lastly, add these two results together. You get 30 (the sum of tens) + 11 (the sum of ones) = 41. So, the sum of 25 and 16 is 41.

Breaking apart addends helps make mental computation of these large numbers easier.

Solve the quadratic function by completing the square. What are the missing pieces in the steps?–32 = 2(x2 + 10x)
–32 + = 2(x2 + 10x + 25)
18 = 2(x + 5)2
9 = (x + 5)2
± = x + 5
x = –2 or x =

Answers

Answer:

x = - 2 or x = - 8

Step-by-step explanation:

Given

2(x² + 10x) = - 32 ( divide both sides by 2 )

x² + 10x = - 16

To complete the square

add ( half the coefficient of the x- term )² to both sides

x² + 2(5)x + 25 = - 16 + 25

(x + 5)² = 9 ( take the square root of both sides )

x + 5 = ± $√(9)$ = ± 3 ( subtract 5 from both sides )

x = - 5 ± 3, thus

x = - 5 + 3 = - 2 or x = - 5 - 3 = - 8

Which equation supports the given conjecture? The sum of the squares of two consecutive integers is an odd integer.

A.
(2 + 3)2

B.
32 + 52 = 34

C.
4 + 52 = 29

D.
52 + 62 = 61

Answers

the first part says the sum of the squares of two consecutive integers or in other words (x)(x)+(x+1)(x+1) so we can cross out A because 2 and 3 are prime numbers (no factors) we can cross out all the others because the square root of 52 is not an integer so any equation with 52 in it does not satisfy the requirement. so none of them are corect. additionally, some of the equations are obviously false such as 52+62=61

The verified answer is wrong the correct answer is d 5 squared plus 6 squared. Because the question is asking for two consecutive integers and it wants an odd integer therefor d is the correct answer because it has to squared consecutive integers and an odd answer.
