At the city Museum child admission is $6.40 in adult admission is $9.70 on Sunday 149 tickets were sold for a total sales of $11
Law Incorporation [45]

Answer:

Adult=58

Step-by-step explanation:

c=child, a=adult

6.4c+9.7a=1145 equation 1

c+a=149 equation 2

a=149-c modified equation 2 to isolate a

6.4c+9.7(149-c)=1145 substitute value of a from equation 1 into equation 2

6.4c+1445.3-9.7c=1145

-3.3c=-300.3

c=91

solve for a

c+a=149

91+a=149

a=58

Check answer:

6.4c+9.7a=1145

6.4(91)+9.7(58)=1145

582.40+562.60=1145

1145=1145

Divide and simplify 4/7÷(-11/2)​
lys-0071 [83]

Answer: -\frac{8}{77}

Step-by-step explanation:

\frac{\frac{4}{7} }{-\frac{11}{2} }

Multiply by the reciprocal in order to get rid of the fraction in the denominator.

\frac{\frac{4}{7} }{-\frac{11}{2} }*-\frac{2}{11}

\frac{4}{7}*-\frac{2}{11}

-\frac{8}{77}
