EXPLANATION
When x=6 and y=13 x+y = 6 + 13 = 19
x + y = 19
Answer:
x = -11, y = 10, z = 4
Step-by-step explanation:
Solve for the first variable in one of the equations, then substitute the result into the other equation.
Answer:
d = (14.75 - (4 × 2.50) ÷ 2
Step-by-step explanation:
the cost of 1 drumstick = d
2.50×4=10.00
14.75-10.00=4.75
4.75÷2=2 3/8
2 3/8 = 2.375
Answer:(3,0)
Explanation:To find the x substitute 0 in for y,7x+3*0=21.Next,multiply 3 and 0,and that gives you 0,7x+0=21 .After you do that you need remove 0 because when you add and subtract zero the quantity doesn’t change,7x=21.Lastly,divid both sides of the equation by 7,and that gives you x=3.
