Answer:
70 / 3
Step-by-step explanation:
x / 7 = 10 / 3
x = ( 10 / 3 ) x 7
= ( 10 x 7 ) / 3
x = 70 / 3
You would distribute -4(3 - 5x) into looking like:
-12 +20x
This gives you
-12 + 20x ≥ -6x + 9
x + 2y = 9
x + 3y = 13
____________________________________________________________
Solve for x in the first equation. Subtract 2y from both sides.
x = 9 - 2y
____________________________________________________________
Plug x into the second equation.
(9 - 2y) + 3y = 13
Combine like terms.
9 + y = 13
Subtract 9 from both sides.
y = 4
____________________________________________________________
Plug y back into the first equation.
x + 2(4) = 9
x + 8 = 9
Subtract 8 from both sides.
x = 1
____________________________________________________________
x = 1
y = 4
Answer:
20 × 10 = 200
Step-by-step explanation:
Multiply 2 × 1 = 2 and then add the two zeros onto the end to get 200.
