Answer:
4(3 + 20)
Step-by-step explanation:
The largest GCF of 12 and 80 is 4. Factor out 4 to get your answer in distributive form.
210 because 209 is closer to 210 than to 200
Answer:
16y-18 = 2(8y-9)
24y+30 = 6(4y+5)
20y+8 = 4(5y+2)
97-15 = 3(3y-5)
Step-by-step explanation:
the bold numbers are the GCF
Answer:
k = 2
x = 2y
Step-by-step explanation:
If variables x and y vary directly, this is expressed as;
x ∝ y
x = ky
k is the proportionality constant
Let's assume the value of x and y since we are not given;
x = 20
y = 10
Substitute
20 = k(10)
10k = 20
k = 20/10
k = 2
Hence the constant of proportionality is 2
Substitute i=k = 2 into the equation x = ky
x = 2y
Hence an equation that relates x and y is x = 2y
<em>Note that the values here are assumed value, you can use the same method for any values of x and y</em>
