Answer:
56
Step-by-step explanation:
she ate 25% so she is left with 75%
you want to find that 25% so you do 75÷25=3
42÷3=14
25×4=100
14×4=56
she had 56 pretzels

Answer:
degrees
Step-by-step explanation:
Sum of 3 angles in a triangle is 180..
The angles given are:
60
7x + 12
1
So we sum to 180 and write:

Also, straight angle is 180 degrees, thus Angle 1 and (14x + 9) angle is sum to 180, thus we can write:

Or we can write this as:

We substitute this expression for Angle 1 into 1st equation we got and solve for x first,

Since x = 9, the angle "14x + 9" would be:
14(9) + 9 = 135
Hence Angle 1 would be:

Based on the graph, f(3) = 5 when x = 3
