Suppose y varies directly as x and y = 24 when x = 3 Find x when y = 88
To solve this problem, we can use the direct variation equation:
y = kx
where k is the constant of variation. We can find the value of k by plugging in the given values into the equation:
24 = k * 3
Dividing both sides by 3 gives us:
k = 24/3 = 8
Now that we have the value of k, we can find x when y = 88 by rearranging the equation:
88 = 8x
Dividing both sides by 8 gives us:
x = 88/8 = 11
Therefore, when y = 88, x = 11.

Given the sum 70=25+45, rewrite 25+45 using their GCF and multiplication.(1 point)
$$
To rewrite 25+45 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 25 and 45, which is 5.
Now we can write it as:
25 + 45 = (5 * 5) + (5 * 9)
Factoring out the GCF, we get:
25 + 45 = 5 * (5 + 9)
Therefore, 25+45 can be rewritten as 5 * (5 + 9).
Given the sum 99=33+66, rewrite 33+66 using their GCF and multiplication.(1 point)
$$
To rewrite 33+66 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 33 and 66, which is 33.
Now we can write it as:
33 + 66 = (33 * 1) + (33 * 2)
Factoring out the GCF, we get:
33 + 66 = 33 * (1 + 2)
Therefore, 33+66 can be rewritten as 33 * (1 + 2).
Given the sum 30=12+18, rewrite 12+18 using their GCF and multiplication.(1 point)
$$
To rewrite 12+18 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 12 and 18, which is 6.
Now we can write it as:
12 + 18 = (6 * 2) + (6 * 3)
Factoring out the GCF, we get:
12 + 18 = 6 * (2 + 3)
Therefore, 12+18 can be rewritten as 6 * (2 + 3).
Given the sum 85, rewrite 35+50 using their GCF and multiplication.(1 point)
$$
To rewrite 35+50 using their greatest common factor (GCF) and multiplication, we first need to find the GCF of 35 and 50, which is 5.
Now we can rewrite it as:
35 + 50 = (5 * 7) + (5 * 10)
Factoring out the GCF, we get:
35 + 50 = 5 * (7 + 10)
Therefore, 35+50 can be rewritten as 5 * (7 + 10).
Given the sum 100=25+75, rewrite 25+75 using their GCF and multiplication.(1 point)

To rewrite 25+75 using their greatest common factor (GCF) and multiplication, we need to find the GCF of 25 and 75, which is 25.
Now we can write it as:
25 + 75 = (25 * 1) + (25 * 3)
Factoring out the GCF, we get:
25 + 75 = 25 * (1 + 3)
Therefore, 25+75 can be rewritten as 25 * (1 + 3).
Philip is sorting acorns he collected. He has 92 acorns: 66 still have their tops, 26 do not.
