2(x+5)=3x+1
x=?
please solve

Answers

Answer:

x=9

Step-by-step explanation:

expand 2(x+5) : 2x+10

2x+10=3x+1

subtract 10 from both sides

2x+10-10=3x+1-10

simplify

2x=3x-9

subtract 3x from both sides

2x-3x=3x-9-3x

simplify

-x=-9

divide both sides by -1 (-1 is equal to -x or -1x)

-x/-1=-9/-1

simplify

x=9

hope this helps :) have a nice day !!

2(x+5)=3x+1
2x+10=3x+1
2x-3x= 1-10

Melanie can run around the track 9 times in 28 minutes. At this rate, how many laps can she run in 1 hour and 15 minutes?

Answers

Step-by-step explanation:

First step is to identify what the problem is asking for and what is given.

9 laps in 28 minutes

Searching for number of laps in 1 hour and 15 min.

1 hour + 15 min. = 75 minutes convert to minutes

9 laps / 28 minutes = x laps / 75 minutes create an equation

9/28 = x/75

9*75 = 28x cross multiply

675 = 28x

x = 675/28 = 24.12 simplify

Melanie can run 24 complete laps in 1 hour and 15 minutes.

Can someone round this to the nearest tenth
3.14 x 4 x 4 x 7
or
3.14 x 7 x 7 x 4
A- 124.6
B- 87.9
C- 97.5
D- 78.9

Answers

Answer:

I think its A

Step-by-step explanation:

I did the math and thats what i got even rounded up

The value of the expression 3.14 x 4 x 4 x 7 is  351.4 and for expression 3.14 x 7 x 7 x 4  is 615.4.

To round the expression to the nearest tenth, we need to evaluate it first. Let's calculate each expression:

3.14 x 4 x 4 x 7 = 351.36

3.14 x 7 x 7 x 4 = 615.44

Now, let's round each result to the nearest tenth:

Rounding 351.36 to the nearest tenth gives us 351.4

Rounding 615.44 to the nearest tenth gives us 615.4

Based on the given options, neither result matches exactly.

However, option A (124.6) is the closest rounded value to 351.4.

When adding fractions all denominators must be the same. You multiple 2/3 by 4 so it becomes 8/12 and the same with the others. The answer is 19/12

Answer:

Leah's mistake was that she did not change the numerators

the correct value is 19/12

the Step-by-step explanation:

(2/3) + (1/2) + (5/12)

= (2*2/3*2) + (1*3/2*3) + (5/12)

= (4/6) + (3/6) + (5/12)

= (7/6) + (5/12)

= (7*2/6*2) + (5/12)

= (14/12) + (5/12)

= (19/12)
