Answer:

e = 9

Step-by-step explanation:

4e - 10 = 2e + 8

=> 4e + (-2e) - 10 = 2e + (-2e) + 8

=> 2e -10 = 8

=> 2e -10 + (+10) = 8 (+10)

=> 2e = 18

=> 2e/2 = 18/2

=> e = 9

Hope this helps!

Answer:

e = 9

Step-by-step explanation:

ok e is just x, so we have to get it alone

4e - 10 = 2e + 8

We move the 2 since its smaller than the 4, and we move it two the other side. 4-2=2 so the new e is 2, now that 8 is alone (since we moved the 2), we cant be having the e with the -10... like this..

2e - 10 = 8, so we now add 10 so it can go with the 8, the new equation is this..

2e = 18

18/2 = 9

simple explanation

4e - 10 = 2e + 8

2e = 18

e = 9

(does that make sense)

Alisa says it is easier to compare the numbers in set a (45,000, 1,025,680) instead of set b (492,111, 409,867). 1.What is one w

DerKrebs [107]

Answer:

1. Set a has two numbers with different number of digits and set b has two number with same number of digits

2. Alissa conjecture is true

3. Her strategy is the number which has the greatest ten thousand place is the greatest number because hundred thousand place has same digit in both numbers

Step-by-step explanation:

* Lets explain how we can solve the problem

- Alisa says it is easier to compare the numbers in set

a (45,000, 1,025,680) instead of set b (492,111, 409,867)

∵ Set a has two numbers one of them 5-digit and the other is 7-digit

∵ Set b has two numbers both of them 6-digit

∴ We can decide whether Alissa conjecture is true or not

1. Set a has two numbers with different number of digits and set b

has two number with same number of digits

- Lets look to set a there are two numbers

45,000 and 1,025,680

∵ The first number formed fro 5 digits and the greatest place value

is ten thousands

∵ The second number formed from 7 digits and the greatest place

value is million

∴ The second number is greatest then the first number

- She did that without looking to the digits and compare them

- Lets look to set b there are two numbers

492,111 and 409,867

∵ The first number formed from six digits and the greatest place

value is hundred thousands

∵ The second number formed from six digits and the greatest place

value is hundred thousands

∴ The two numbers have same number of digits

∴ We must start to compare the digits from greatest place value

- She must compare the corresponding digits to find the greatest one

2. Alissa conjecture is true because she can compare the number in

set a by counting the number of digits but in set b she must

compare the corresponding digits

∵ The greatest place value is hundred thousands and the two

numbers have the same digit 4 in this place, so she must look

to the ten thousand place

∵ The ten thousands digit in the first number is 9

∵ The ten thousands digit in the second number is 0

∵ 9 > 0

∴ The first number is greater than the second number

3. Her strategy is the number which has the greatest ten thousand

place is the greatest number because hundred thousand place

has same digit in both numbers

The record time for running the Boston Marathon is 2.12 hours at an average speed of 12.5 miles per hour. What distance does the

Elena-2011 [213]

Answer:

26.5 $\ miles$

Step-by-step explanation:

Given: Times for running Boston Marathon= $2.12\ h$

Speed= $12.5 \ mph$

Now, finding the distance covered in Boston Marathon.

Distance covered= $Speed \times times$

Distance covered = $12.5 \times 2.12 = 26.5 \ miles$

∴ Distance covered in the Boston Marathon is 26.5 $\ miles$

here a subtraction problem that has been solved incorrectly what is the right answer for 74-25=59 but do it in the addition sent

madam [21]

Answer:

the equation is wrong

Step-by-step explanation:

=> 74-25=59

since 74 - 25 equals to 59 in order to find the addition sentence that will check the subtraction problem is true and 59 and 3/5 or you can add add 59 and 25 to check if the problem was solved correctly

=> 59+25

add 59 to 25

=> 84

this means the question is wrong
