At a carnival, 700 tickets were sold for a total amount of $5,500. An adult ticket cost $10 and a children’s ticket cost $5. Find the number of adult tickets and the number of children’s tickets sold. (Solve by substitution)

answer are

step-by-step explanation:

2. angles qrt and qst both measures 156 degrees.

step-by-step explanation:  

we have been given a diagram of a circle and we are told that measure of arc qvt is 156 degrees.  

we can see from our given diagram that angle qrt and angle qst subtends to arc qvt.

since we know that angles subtended by the same arc at the circumference are always equal.

by angle subtended by same arc theorem, measure of angle qrt and angle qst will be equal to the measure of arc qvt.

therefore, angles qrt and qst both measures 156 degrees and 2nd statement is the correct choice.

yes the total will be same because in both of them the expression.is rearranged but their sign remains the same hence it hss just been shuffled

step-by-step explanation:

the true statements are:

r = set of real numbers

n = set of natural numbers, 1,2,

w = n u{0} = {0,1,}
