Answer:
A : D
4 : 3
Step-by-step explanation:
We'll use the first letter of their names as the heading for the ratio.
The first line states:
A : B
2 : 1
The second line states:
B : C
1/3 : 1
The third line states:
C : D
2 : 1
We have three different ratios but we know that they are related to one another so we are going to combine them by equating the common ratio of the different ratios.
Let's look at the ratio with a fraction first.
B : C
1/3 : 1
If we ×3 throughout, this can also be written as:
B : C
1 : 3
Now B in the first and second ratio is the same number and we are able to combine them. We can write them all together like this:
A : B : C
2 : 1 : 3
In the third ratio, C is 2, however in the ratio we have now C is 3. We can make them the same number by ×3 throughout the third ratio and ×2 throughout the ratio we have now.
C : D
2 : 1
6 : 3
A : B : C
2 : 1 : 3
4 : 2 : 6
We can see that our ratio for C is the same number and we can now combine the ratios.
A : B : C : D
4 : 2 : 6 : 3
The question asked for A : D so we can take just the values of A and D.
A : D
4 : 3
I hope this helps :)
Hi there! So Elbert made 48% of his shots. To find out how many shots he made, all you have to do is multiply the amount of shots he attempted by the percentage. 25 * 48% is 12. There. Elbert scored 12 baskets.
A place value chart can help us in finding and comparing the place value of the digits in numbers through millions. The place value of a digit increases by ten times as we move left on the place value chart and decreases by ten times as we move right.
Answer:
y=−x−1/3x−8
Step-by-step explanation:
y=8x−1/3x+1
To find the inverse function, swap x and y, and solve the resulting equation for x.
If the initial function is not one-to-one, then there will be more than one inverse.
So, swap the variables: y=8x−1/3x+1 becomes x=8y−1/3y+1.
Now, solve the equation x=8y−1/3y+1 for y.
y=−x−1/3x−8
Sorry I was in a rush and couldn't do the fractions as formulae. Hope it helped anyways.
