The event coordinator asks you to determine how many students participated in the track-and-field day. The total number of students in seventh and eighth grade combined is 584; 5/8 of them are seventh graders and 3/8 of them are eighth graders. If 4/5 of the seventh graders participated in track-and-field day and 7/8 of the eighth graders participated, about how many total students participated? Describe the process you used to find your answer.
Answer:
584 is the total number of students in the school.
5/8 are in seventh grade and 3/8 are in eighth grade.
4/5 of the seventh graders participated in the track meet, so there were (4/5 · 5/8) · 584 students in the seventh grade participating in the track meet.
7/8 of the eighth graders participated, so there were (7/8 · 3/8) · 584 students in the eighth grade participating in the track meet.
So, all together, there were
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 students from the school in the track meet.
Let's simplify as you asked:
(4/5 · 5/8) · 584 + (7/8 · 3/8) · 584 = [(4/5 · 5/8) + (7/8 · 3/8)] · 584 (distributive property - factoring)
= [20/40 + 21/64] · 584 (multiply fractions)
= (1/2 + 21/64) 584 (reduce the first fraction to lowest terms)
= (32/64 + 21/64) 584 (getting a common denominator)
= (53/64) 584 (combine/add the two fractions)
= 483.625 (multiply together)
All together, there were: 483.625 students in the meet.

Miranda feeds her fish 12 milligrams of food every 3 days. About how many millagrams of food will she need to feed her fish for 32 days?
Answer:
128 miligrams for 32 days
Step-by-step explanation:
To do this question, you first need to find out how much food she feeds per day so to do this, you do 12 mg/3 days and you get 4mg/day.
Then you multiply this number by 32.
4mg/day (32 days) = 128 mg
Procedure :
12 milligrams - 3 days
(3 divided by 12 = 4)
4 - day
4 x 32 = 128
Answer :
To feed her fish for 32 days, she will need 128 milligrams of fish food.
The dinosaur's tail bones are at the solution point to the system of equations below.
–2x – 7y = –250
4x – y = 140
Every time you click a point using the CPS, the equations below will update. Remember, the solution is the point that makes both equations true.
–2( 1 ) – 7( 36 ) = -254 X
4( 1 ) – ( 36 ) = -32 X
Answer:
x = 41
y = 24
Step-by-step explanation:
Systems of equations is,
-2x - 7y = -250 ------(1)
4x - y = 140 ------(2)
Equation (1) multiplied by 2 then added to equation (2)
-4x -14y = -500
(+) 4x - y = 140
-15y = -360
y =
y = 24
by putting y = 24 in equation (2),
4x - 24 = 140
4x = 140 + 24
x =
x = 41
For x = 41 and y = 24 both the equations are true.
Equation (1), -2(41) - 7(24) = -250 [True]
Equation (2), 4(41) - (24) = 140 [True]
