Answer:
x=1/2
Step-by-step explanation:
Distribute the 10. it will be 20x-40=100x. Subtract 20x from both sides. it will be 40=80x. Divide by 80 to leave the x by itself. x=40/80...in simplify form....its 1/2
2x + 4 + 124 = 180 (<span>supplementary sum = 180)
2x + 128 = 180
2x = 52
x = 26</span>
Answer:
Hopefully you can read it
Step-by-step explanation:
Replace x in the equation with 3.5 and do the arithmetic.
y = 1.3*3.5 -0.52
y = 4.55 -0.52
y = 4.03
The predicted approximate value of y is 4.03.
