Answer:
y = 2x + 2
Step-by-step explanation:
6x -3y = -6 (get y on one side of the equals sign by substracting 6x from both sides)
-3y = -6x - 6 (divide each side by -3 to get final value of y)
y = 2x + 2
Answer:
6.8
Step-by-step explanation:
Answer:
x = 17
Step-by-step explanation:
First, let's turn this into an equation:
twenty more ( +20 ) than four times a number ( 4x ) is equal ( = ) to the difference ( - ) between 139 and 3 times the number ( 3x ).
4x + 20 = 139 - 3x
Now let's solve:
Subtract 20 from each side:
4x = 119 - 3x
Add 3x to each side:
7x = 119
Divide each side by 7:
x = 17
Joe walked 4/9 of a mile in 4/5 of an hour.
4/9 mile= 715.264 metres
4/5 hour= 48 minutes
715.264/48= 14.902 metres/ minute
14.902 x 60= 894.12 metres/hour.
= 0.556 miles/ hour.
Writing an equation would be most helpful, but depending on the situation drawing a diagram or reading a table could work better.
