Write an expression that is equivalent to 5(3x plus 2z)

State if the two triangles are congruent. if they are, state how you know?

Solve the problem. a student earned grades of c, a, b, and a in four different courses. those courses had these corresponding numbers of credit hours: 4, 5, 1, and 5. the grading system assigns quality points to letter grades as follows: a = 4, b = 3, c = 2, d = 1, and f = 0. compute the grade point average (gpa) and round the result to two decimal places. 3.40 3.50 8.75 2.18

3x + 4y = 5 x- 3y = -7 solve by substitution
