Hi there
Let's order the transactions
on May 1. 150
less On May 20 100 books were sold
Less June 3, 31 books were purchased by the students
Add on June 15 25 books arrived
Add On June 17, a shipment of 150 books arrived
So
the number on hand on June 17
150−100−31+25+150
=194....answer
Hope it helps
|-3|=3 right?
Then it is
3*-6=-18
It’s c because if you look at it shows that it could do straight line
Answer:
−438°, -78°, 642°
Step-by-step explanation:
Given angle:
282°
To find the co-terminal angles of the given angle.
Solution:
Co-terminal angles are all those angles having same initial sides as well as terminal sides.
To find the positive co-terminal of an angle between 360°-720° we will add the angle to 360°
So, we have: 
To find the negative co-terminal of an angle between 0° to -360° we add it to -360°
So, we have: 
To find the negative co-terminal of an angle between -360° to -720° we add it to -720°
So, we have: 
Thus, the co-terminal angles for 282° are:
−438°, -78°, 642°
Answer:
Adults $ 17
Students: $8
Step-by-step explanation:
Adults: x
Students: y
a) 25x + 31y = 673
b) 27x +31y = 707
Elimination:
a) -1(25x + 31y = 673) = -25 -31y = -673
a + b
= (-25 -31y = -673) + (27x + 31y = 707)
= 2x = 34
x = 34/2
x = 17
Substitution a or b:
a) 25(17) + 31y = 673
425 + 31y = 673
31y = 673 - 425
31y = 248
y = 248/31
y = 8
