Replace the informations you don't know with letters.

x = number of bags
y = number of sandwiches

7x + 3y = 22
3x + y = 8

Then solve the equations.
First, isolate the y in the second one like this :
y = 8 - 3x

then replace the y in the first equation with its worth from the second equation :

7x + 3(8 - 3x) = 22

solve for x, then replace the value in the equations to get the value of y

Which of the following statements is true?
Ivahew [28]

The correct answer is C. A scalene triangle can be a right triangle.


This is because a scalene triangle is a triangle where all of the sides and angles are different from one another. This automatically tells us that options A and D are incorrect, because equiangular triangles have all 3 angles equivalent and if two sides were of equal length in the triangle, then it would not be scalene.


This leaves us with options B and C. An obtuse triangle simply has one angle with a measure greater than 90 degrees, and a right triangle is a triangle with a right angle (an angle that measures exactly 90 degrees). Scalene triangles can be both obtuse and right, as long as the side lengths and angles are not equal to one another. This makes option B incorrect, and option C the only correct option out of the four.


Your answer is option C.


Hope this helps!

Solve they system by addition 7x-2y=3 4x+5y=3.25
noname [10]

Answer: x = 2/7y + 3/7 and

x= -5/4y + 0.8125

Step-by-step explanation: Let's solve for x.

7x−2y=3

Step 1: Add 2y to both sides.

7x − 2y + 2y= 3 + 2y

7x = 2y + 3

Step 2: Divide both sides by 7.

7x/7 = 2y+3/7    this is for the second answer                                                  Step 1: Add -5y to both sides.

4x+5y+−5y=3.25+−5y

4x=−5y+3.25

Step 2: Divide both sides by

4/4 x 4 = −5y + 3.25/4
