Giles is making tacos for dinner and bought some beef and chicken. At the store, he bought twice as much beef as chicken. The chicken costs $1.85 per pound, and the beef costs $3.70 per pound. Before sales tax, Giles spent a total of $12.95 on beef and chicken. The system of equations below represent the pounds of chicken, x, and pounds of beef, y, that Giles purchased. Part A: Use the ray tool to graph the system of equations on the coordinate plane. Part B: Use the point tool to select the approximate pounds of beef Giles purchased.

The answer is below

Step-by-step explanation:

Chicken costs $1.85 per pound, and the beef costs $3.70 per pound. Let x represent the pounds of chicken and y represent the pound of beef. If he spent a total of $12.95, therefore:

1.85x + 3.7y = 12.95           (1)

He bought twice as much beef as chicken, therefore:

y = 2x

y - 2x = 0                             (2)

Solving eqn 1 and eqn 2 simultaneously. Multiply equation (2) by 3.7 and subtract from equation (1)

9.25x = 12.95

x = 1.4 pounds

Also substitute x = 1.4 in equation 2:

y - 2(1.4) = 0

y = 2(1.4)

y = 2.8 pounds

The graph was plotted using geogra, the y coordinate of the point of intersection of the two lines, is the approximate pounds of beef.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq
