# Which pair of numbers has the same gcf as that of 48 and 78A)4 and 34B)8 and 18C)9 and 15D)12 and 30

Answer: greatest common factor is found by finding the factors of each
factors48=2 times 2 times 2 times 2 times 3
78=2 times 3 times 13
find common group
comon group=2 times 2=6
gcf=6
find others
narrow it down by crossing out any choices with numbers not divisible by 6
(crosses out A,B,C since A has 4 and B has 8 and C has 9)

therefor the answer is D, 12 and 18
check
12=2 times 2 times 3
18=2 times 3 times 3
common group=2 times 3=6
correct

answer is D, 12 and 18

What is 7/9 divided by 2 13/18

7/9 divided by 2 13/18 is 2/7
hoped this helps

To divide 7/9 by 2 13/18, convert the mixed number to an improper fraction, then multiply the fractions and simplify. The result is 42/141.

### Explanation:

To divide 7/9 by 2 13/18, we need to convert the mixed number 2 13/18 into an improper fraction. To do this, we multiply the whole number (2) by the denominator of the fraction (18) and add the numerator (13). This gives us 47. So, 2 13/18 can be written as the improper fraction 47/18.

Now, we can divide 7/9 by 47/18. We multiply the first fraction by the reciprocal of the second fraction (flip the numerator and denominator). So, (7/9) ÷ (47/18) becomes (7/9) × (18/47).

To multiply fractions, we multiply the numerators together and the denominators together. This gives us (7/9) × (18/47) = (7 × 18) / (9 × 47) = 126/423.

Lastly, we can simplify the fraction by dividing the numerator and denominator by their greatest common divisor. The GCD of 126 and 423 is 3. Dividing both numerator and denominator by 3 gives us the simplified answer: 42/141.

Two-ninths of the total number of batteries in Richard's desk drawer is madeup of 16 batteries. How many batteries are there in the drawer?

You are told 2/9 = 16

Let total number of batteries = x

So you now have 2/9x = 16

To find x divide both sides by 2/9

X = 72 total batteries

Awnser

72

i dunno how to explain i did it in my head

Solve with steps for this questions

see explanation

Step-by-step explanation:

given

g(x) = 3x² - 5 then g(t) = 3t² - 5

Also g(t) = - t, hence

3t² - 5 = - t

multiply both sides by 2 to eliminate the fraction

6t² - 10 = - 7t ( add 7t to both sides )

6t² + 7t - 10 = 0 ← in standard form

(t + 2)(6t - 5) = 0 ← in factored form

Equate each factor to zero and solve for t

t + 2 = 0 ⇒ t = - 2

6t - 5 = 0 ⇒ t =

7/2t. That’s my answer but sorry I didn’t work it out
