So the GCF of both 8 and 20 is 4 because 2 x 4 is 8 and 5 x 4 is 20 4 is the greatest number that can go into them. To do distributive property you put the GCF outside the parentheses like this: 4( for the inside you just put the multiplication you would do 4x2 is 8 and 4x5 is 20 4(2 + 5) = 8 + 20
Answer:
The difference in weights = pounds
Step-by-step explanation:
"DIFFERENCE" means to subtract their weights. We will subtract lesser amount from the greater amount to get our answer.
Also, we need to first make these mixed numbers into improper fractions by using the rule below:
If a number is given in this form:
We can do the operation below to make it improper fraction:
The bigger number is . So we subtract the other from this after changing to improper fraction.
and
Now, we subtract via doing LCM and get our answer:
The difference in weights = pounds
Answer:
45
Step-by-step explanation:
Answer:
y=2x+3
Step-by-step explanation:
Hi there!
We want to write the equation of the line
We are given that the y-intercept of the line is (0,3) and that the line also goes through the point (2,7)
There are many ways to write the equation of the line, but the most common way is slope-intercept form, which is given as y=mx+b, where m is the slope and b is the y intercept
The value of b is actually the value of y in the point making point of the y intercept
In this case, that point would be 3
So the value of b in this case is 3
Substitute 3 as b into the equation:
y=mx+3
Now we need to find m
As the equation passes through the point (2,7), we can use it to help solve for the value of m
Substitute 2 as x and 7 as y into the equation:
7=2m+3
Subtract 3 from both sides
4=2m
Divide both sides by 2
m=2
Substitute 2 as m into the equation:
y=2x+3
Hope this helps!
