A large box of crackers weighs 20 oz. If James needs 3 pounds of crackers for a party, how many boxes of crackers should he buy?

andre [41]

If James needs 3 pounds of crackers, and
each box is 200z, that means each box is a little over 1 pound. (1.25 pounds to be exact). So, we know that he needs to buy 3 boxes of crackers. This is because 20×3=60 ounces which is 3.75 pounds. Meaning, 3 boxes is the correct answer since we can't cut a box in half.

Plot a point C that divides the segment into the ratio AC:AB= 3/4

aalyn [17]

Given :

A graph .

To Find :

A point C that divides the segment into the ratio AC:AB= 3/4 .

Solution :

From the graph we can see that point A and B are ( 1 , -2 ) and ( 5 , 6 ) respectively .

Now , we know point which divide a line segment with end point $(x_1,y_1)$ and $(x_2,y_2)$ in m : n is :

$x=\dfrac{mx_2+nx_1}{m+n}\ ,\ y=\dfrac{my_2+ny_1}{m+n}$

Putting all given values we get :

$x=\dfrac{3(5)+4(1)}{3+4}\ ,\ y=\dfrac{3(6)+4(-2)}{3+4}\\\\x=\dfrac{19}{7}\ ,\ y =\dfrac{10}{7}$

Therefore , point C is $(\dfrac{19}{7},\dfrac{10}{7})$ .

Hence , this is the required solution .

How to do this? Solve for x

goldfiish [28.3K]

X=3

okay so Angles YXZ and YZX are congruent.
180 = 136 + 2(10x-8).
180-136 = 2(10x-8).
44 = 2(10x-8).
44/2 = 10x-8.
22=10x-8.
22+8 = 10x.
30 = 10x.
3 = x.
