Answer:
OR
Step-by-step explanation:
Let's first simplify .
5 and 15 multiply to get 75. 5 and 3 multiply to get 15. Since we have a pair of fives and a three leftover, we can write as:
Now, let's find the answer in decimal form. We know that:
and
With that information, we know that the answer has to be between 8 and 9.
Divide 75 by 8:
Take the average of that answer and 8:
This answer we got is extremely close to the exact answer of , which is . Since we are estimating, the answer above will do just fine.
Answer:
y=1.5x-8
Step-by-step explanation:
this is because you first need to fond the change in the x axis and the y axis which will give you the gradient. Then you will have to substitute any co-ordinate and gives you c.(Y=mx+c) is the equation of a straight line.
Answer:
12 m
Step-by-step explanation:
perimeter is all of the sides together, so 2 7's and 2 x's. You would subtract 14 from 38 to get 24, then divide it by 2 to get the missing side, which is 12
The greatest common factor is 3.
