Answer:
they both has 7 slides and the presentation had a duration of 28 seconds
Step-by-step explanation:
we have to setup equation that makes them equal to each other if you know what i mean. 2x+16=3x+10
then we just solve for x
2x+16=3x+10
subtract 10 from each side
2x+6=3x
step 2 subtract 2x from each side
x=6
so both of their presentations are 7 slides long
then to find the length of their presentations we just plug in 6 to one of the equations
2(6)+16
2x6=12 12+16=28 so both of their presentations were 28 seconds

Answer:
125
Step-by-step explanation:
A is an inscribed angle. The central angle is 90, so angle A is 45.
110/2 = 55
180 - 45 - 55 = 80
Angle B is 80.
80 + 45 = 125
Answer:
1. x = 17
Step-by-step explanation:
4x - 9 + 5x + 2 + 2x = 180
11x - 7 =180
11x = 180 + 7
x = 187 / 11
x = 17
