Answer:
-5 coach tickets
-8 first class tickets
Step-by-step explanation:
let x be the number of coach tickets and y the number of first class tickets:
Given that coach tickets costs $260 each, and first class tickets $1080 and that the total fare budget was $9940:
#From equation i, make x the subject of the formula:
#Substitute x in ii;
Hence, Sarah bought 5 coach tickets and 8 first class tickets.
A is the correct answer!
81 is a negative, so the 9’s have to be a positive and a negative
hope this helps!
If you continue the top ray down to the lower our the two lines you create an angle that it's an exterior angle of a triangle and it's also a corresponding angle to the 110° angle. since corresponding angles are congruent this angles is also 110°. this angle makes a linear pair with the angle to it left, the lower right angle on the triangle. linear pairs add to 180° so the angle has to be 70°. the lower left angle of this triangle is given as 37°. since the 3 angles of a triangle must add to 180° , the top angle has to be 180-(70+37)=73. since the top angle of the triangle makes a linear pair with the angle in question, our angle has to be 180-73=107°
Answer:
C is a constant ( a value that doesn't change)
Step-by-step explanation:
for example (X^2), here x is a variable with an exponent. (8x), here 8 is a coefficient. making c a constant.
