The measures of the angles of a triangle are shown in the figure below. Solve for x. ​

Explain step-by-step how to simplify -5(2x – 3y + 6z – 10).

Tomas is making trail mix using granola and walnuts. he can spend a total of $12 on the ingredients. he buys 3 pounds of granola that costs $2.00 per pound. the walnuts cost $6 per pound. he uses the equation to represent the total cost, where x represents the number of pounds of granola and y represents the number of pounds of walnuts. he solves the equation for y, the number of pounds of walnuts he can buy. answer- b tomas added 6 to both sides of the equation instead of subtracting 6. just took the test

Ijust need to see how to do this. so you don’t have to answer all of them just a step by step explanation of one.
