What is the value of w in the solution to the following system of linear equations ? 5v+4w=1 3v-6w=2 a -7/18 b -1/6 c-1/9 d1/3

1. what is the measure of ∠abc? what is the measure of ∠abd?

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

Which shows the correct substitution of the values a,b and c from the equation 1=-2x+3x^2+1
