Answer:
y = −4
Step-by-step explanation:
On the bottom line, the 106 and number 1 make a straight line and needs to equal 180 degrees.
This means number 1 = 180-106 = 74 degrees.
Because x and y are parallel, the top outside angle is the same as number 1.
6x +8 = 74
Subtract 8 from both sides:
6x = 66
divide both sides by 6:
x = 66 / 6
x = 11
Now you have x, replace x in the equation for 7x-2 to find that angle:
7(11) -2 = 77-2 = 75 degrees.
The three inside angles need to equal 180 degrees.
Angle 2 = 180 - 74 - 75 = 31 degrees.
Answer:
He can make 12 batches of pancake
Step-by-step explanation:
Total amount of milk = 9 cups
One batch of pancake uses 3/4 cup of milk.
y batch of pancake uses 9 cup of milk.
Therefore ( y ) x (3/4) = 9
Step-by-step explanation:
x = 7
3 + 4x = 5x - 4
3 + 4(7) = 5(7) - 4
3 + 28 = 35 - 4
31 = 31
