1 answer:

5 0

To calculate the GCF, you need to list all the prime numbers that will go into each number listed

12: 2, 2, 3
60: 2, 2, 3 5
68: 2,2,17

Now you circle the numbers that are the same in each.

GCF: 2, 2

Multiply these numbers to find the GCF: 4

Cristina bought a bag of coffee for $8.47. The weight of the bag was 7/8 of a pound. What was the price, per pound, of the coffe

SpyIntel [72]

~For this problem, you need to divide.
~The easy way that I think might help you is if you change the fraction into a decimal.

$\frac{7}{8} = 0.875$

Now divide $8.47 by 0.875
$\frac{8.47}{0.875} = 9.68$

The price per pound of the coffee was $9.68

Complete the division problem by determining the number that should be placed in the box.

Assoli18 [71]

The solution 349 is given, and its number 3, 4 and 9 determine how many times 13 can be subtracted:

The first subtraction is 3x13 (x100) = 3900
The second subtraction is 4x13 (x10) = 520
The third subtraction is 6x13 = 78

So the answer is 520, which is also what you get when you subtract 78 from 598 of course.

After substituting, what is the first operation performed when evaluating 5 + (9 x minus 3) divide 2 for x = 5? addition multipl

ludmilkaskok [199]

Answer:

<h2>Multiplication.</h2>

Step-by-step explanation:

The given expression is

$5+(9x-3) \div 2$

For $x=5$ , we have

$5+(9(5)-3) \div 2$

Notice that the first operation we need to do is multiplication, because that's the right order of operations when we solve these kind of expressions.

$5+(45-3) \div 2$

Then, we subtract

$5+42 \div 2$

Now, we divide

$5+21$

Finally, we sum

$26$

Therefore, the right answer is multiplication.
