A’s answer is 7
b’s answer is 5
hope this helps!
The difference between 10, 17 and 24 is 7, so we can write 7n
To get from 7 to 10 you add 3.
This can be written as 7n+3
Substitute 46 into n
7(46)+3
=325
I hope this helps.

Answer:
1764 cm²
Step-by-step explanation:
(45 * 12 * 2) + (45 * 6 * 2) + (12 * 6 * 2) = total surface area
= 1764
Answer:
The ratios are not equal.
Step-by-step explanation:
To justify the answer we will assume the dimes and quarters.
Let number of dimes be denoted by 'x'.
Let number of quarters denoted by 'y'.
In Siri's coin purse
Number of dimes (x) = 6
Number of quarters (y) = 4
Therefore ratio of quarter to dimes we get;
⇒ equation 1.
In Martha Coin purse.
Number of dimes (x) = 5
Number of quarters (y) = 3
Therefore ratio of quarter to dimes we get;
⇒ equation 2.
Now we will check if both have the same ratios.
We will check by making both equation 1 and equation 2 equal.
By cross multiplication we get;
Hence the ratios are not equal.
Answer:
25/√1658
Step-by-step explanation:
To do that division, you just need to do that simple division. However, let me tell you that the way to do that division, is rationalizating the dividend. This is because in a division, they cannot be any kind of square root. So the mechanical procedure to this is the following:
Start dividing:
25 / √1658
Now, rationalize:
25 / √1658 * √1658 / √1658
This step is to eliminate the square root from the dividend. Then:
25 * √1658 / 1658
Now when you do the math, you should get an accurate result.
