I believe that D might be 6, and O might be 7 but I really don't know what G is. Can someone help me answer this please.
marysya [2.9K]

Answer:

  DOG = 270

Step-by-step explanation:

270 × 3 = 810

_____

The only numbers that end in the same digit when multiplied by 3 are 0 and 5.

  0×3 = 0

  5×3 = 15

If G is 5, then you are looking for digits DO than give a product of 80 when multiplied by 3. 80 is not divisible by 3, so that doesn't work.

G must be 0.

Then the product of DO and 3 is 81, so DO = 81/3 = 27.

The solution is ...

  D = 2

  O = 7

  G = 0

frez [133]

Answer:

The slope is 5/3 and the y-int is -2

Step-by-step explanation:

<u>Step 1:  Identify the slope </u>

The slope is the number attached to the x.  Therefore, the slope is 5/3.

<u>Step 2:  Identify the y-int </u>

The y-int is the number that is after the x

y = mx + b

Therefore, the y-int is -2
