To find the area of the paper. You must multiply the width and the height, which is 9 and 19.
9 x 19 is 171
And multiply that by 4
171 x 4 = 684
Total area is 684
Answer:
61
Step-by-step explanation:
The sum of the three angles of any triangle is equal to 180 degrees.
180-58=122
122/2=61
We divide by two because we are missing the other two angles but they are both equal.

Answer:
<em>Equation; y = - x + 3</em>
Step-by-step explanation:
To determine the equation, let us first determine the slope of the line, through the equation ( y2 - y1 ) / ( x2 - x1 ), in this case where y2 ⇒ 1, y1 ⇒ 5, x2 ⇒ 2, and x1 ⇒ -2;
( 1 - 5 ) / ( 2 - ( - 2 ) ) ⇒ Simplify,
( - 4 ) / ( 4 ),
<em>Slope; - 1</em>
Now that we have the slope, let us substitute this known value into the point - slope equation in the following form;
y = a * x + b, where a ⇒ slope, and b ⇒ y - intercept,
( So far we have ) y = - x + b,
Let us solve for the value of b in y = - x + b by substituting one of the points, say ( 2 , 1 ) where x ⇒ 2, and y ⇒ 1;
( 1 ) = - ( 2 ) + b,
1 = - 2 + b,
b = 3;
<em>Equation; y = - x + 3</em>
Answer:
He spent 1.89 for 1 spool of thread
Step-by-step explanation:
1) 8.99 x 3 = 26.97 because He buys three yards of fabric at $8.99 per yard
2) 32.64 - 26.97 = 5.67 because we need to figure out what part of the total was spent on the spool of thread.
3) 5.67 / 3 = 1.89 because he bought three spoils of thread and I want to know the price of one.
