<h2>Answer:</h2>
The equation that is used to model the length of ladder in terms of x is:
We can model this problem with the help of a right angled triangle whose hypotenuse is 13 meters and the other two legs are x meters and (x-7) meters.
where x is the distance between the top of the ladder and the ground.
and (x-7) is the distance between the foot of the ladder and the wall.
Hence, using Pythagorean Theorem we have:
Hence, the answer is:
Answer:
3 yards of fabric
Step-by-step explanation:
In order to solve this problem, we should first make all of the fractions have common denominators. To do so we can turn the 1/2s into 2/4 which both equal 0.5 or 50%. Now we simply need to add together the pieces of quilt that she has and subtract that value from the total that she needs in order to calculate the amount of quilt that she is missing.
10 - (2
+ 4
) = x
10 - 6
= x
3 = x
Finally, we can see that Rebecca needs a total of 3 yards of fabric to finish her quilt.
