Answer:
10 years
Step-by-step explanation:
30 + 10 = 40
10 + 10 = 20
20 is half of 40
So the first step to solving this problem is to distribute the {1}{4}
to what's inside the parenthesis. This means multiply {1}{4} by 4x and 15.
After that, this is what you should have.
{4x}{4} + {15}{4} = 24
This should be simplified
1x = 24 - {15}{4}
{15}{4} is equal to 3.75
x = 20.25
20.25 is equal to {81}{4}
I think this is how it done

Answer:
3/4
Step-by-step explanation:
If slope is 1/4, you have to assume it is multiplied by x. x in the second coordinate is 3. So you place in
1/4(x)=y
1/4(3)=y
3/4=y
And the other one is incorrect
1/4(x)=y
1/4(7)=y
1 3/4 =y

Answer:

Step-by-step explanation:
thats kinda sus but 8-1
I would guess and check. For example, let's say there are 15 yellow marbles. Multiply by 5 and add 3 to get 78, which means it's too much. Then I guessed 8. 8 times 5 plus 3 is 43. Then I added 8 to 43 to see how many total, which would make 51. Now it's to less. Then I guessed 10. Having 10 yellow means 53 white, which is 63 total. Too many again. Then I guessed 9. 9 yellow is 48 white, which makes a total of 57. So therefore, the answer is 48 white marbles.
