A matinee ticket costs $6 per adult and $1 per child. On a certain day, the total
number of adults (a) and children (c) who saw a movie was 35, and the total money
collected was $70. Which of the following options represents the number of children
and the number of adults who saw a movie that day, and the pair of equations that
can be solved to find the numbers? (4 points)
PM
28 children and 7 adults
Equation 1: a + c-35
Equation 2: 6a + c = 70
PM
0 28 children and 7 adults
Equation 1: a + C-35
Equation 2: 6a-c-70
PM
O 7 children and 28 adults
Equation 1: a + c = 35
Equation 2: 6a - C = 70
3 PM
O 7 children and 28 adults
Equation 1: a + C-35
Equation 2: 6a + C-70

d. millimeters per hour.

step-by-step explanation:

we are given that,

carlo used a rain gauge to measure the amount of water his lawn is receiving from the sprinklers.

since, according to the options, we see that,

water cannot be measured by 'miles per hour', 'meters per second' and 'grams per seconds'.

we get that, the water can be measured by 'millimeters per hour'.

hence, the appropriate rate for describing the amount of water is 'millimeters per hour'.

a)(x-2)^2+(y-1)^2=9

step-by-step explanation:

answer: bea's uncle is 25 years old.

step-by-step explanation:

given the equation , we can say that the variable "x" represents the age of bea's uncle. then to find his age, we need to solve for "x":

we must add 15 to both sides of the equation:

now we need to divide both sides of the equation by 3:

therefore, we can conclude that bea's uncle is 25 years old.
