Needgiven the system of linear equations. choose all of the options that could be used to solve the system using addition x + y = 7 2x + y = 5 (could be more than one answer) 1.multiply the first equation by -1 and add the equations together. 2.multiply the second equation by -1 and the first equation by -1, then add the equations together. 3.multiply the second equation by -1 and add the equations together. 4.multiply the first equation by -2 and add the equations together. 5.multiply the first equation by 2 and the second equation by -1, then add the equations together.

hey there!

12 is twice as much as 6 because 6 goes into 12 2 times.

since the rabbit is twice as tall, we should multiply the weight of the first rabbit, 0.25, by 2.

0.25 x 2 = 0.5

therefore, the 12 inch chocolate rabbit weighs 0.5 lb, or half a pound.

hope this !

circle area = pi * radius^2

if diameter = 10 then radius = 5

circle area = pi * 5^2

circle area = pi * 25

circle area = 78.5398163397 square units

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
