Roman was studying the life of fish, frogs, and turtles in
Doyle Park. In two hours, he counted 4 more frogs than
turtles. The number of fish he counted was twice the
number of turtles. In total, he counted 68 animals. How
many fish were there?
how many frogs were there? how many turtles were there?
Answer:
16 turtles
20 frogs
32 fish
Step-by-step explanation:
let 't' = # turtles
let '4 + t' = # frogs
let '2t' = # fish
t + 4 + t + 2t = 68
4t + 4 = 68
4t = 64
t = 16 turtles
4 + 16 = 20 frogs
2(16) = 32 fish

Clive draws △MNR, with MN = 2 cm, NR = 4 cm, and RM = 3 cm. Which triangle represents Clive's triangle?
Answer:
Scalene Triangle
Step-by-step explanation:
We are told that he drew a triangle MNR. Now, the sides are given as;
MN = 2 cm
NR = 4 cm
RM = 3 cm
This means that the 3 sides are not equal. And a triangle with it's 3 sides being unequal is called a scale me triangle.

4y+6 for y-12
Evaluate the expression.
Answer:
54
Step-by-step explanation:
I think what you mean is y = 12, so I'll just go off that. So we substitute 12 for y and we get 4*12 + 6. Then we multiply. 48 + 6 and we get 54! I hope this helped and please mark brainliest!

identify the relationship between angles f, b, and a in the above diagram. PLEASE HELP WILL GIVE BRAINLIEST 7TH GRADE MATH
Answer:
Just remember that straight lines are always 180° (a + b = f)
Step-by-step explanation:
Assuming the triangle is equiangular and equilateral, a b and c are the same, so they are interchangeable.
f + c = 180 becuase it is a straight line. you can switch out c with a because they are the same. So:
f+a=180
(switch out with b)
f+b=180
GUESSING this is equiangular, a and b must add up to 120 because they are are both 60.
If a line is 180 degrees and c is 60 (same as a and b) then f will be 180-60 which is 120. 120 is the same as the sum of a and b, so you could write:
a + b = f
The relationship between angles f, b, and a could be as a + b = f.
What is linear pair?Linear pair of angles are produced when two lines intersect each other at a point. The sum of angles of the linear pair is always 180 degrees.
WE can see that the triangle is equiangular and equilateral, Also angles a b and c are the same, so they are interchangeable.
WE know that the base makes the straight line
f + c = 180
So: f + a = 180
Similarly
f + b = 180
Assuming this is equiangular, a and b must be add to 120, they are both 60 degrees
If we consider the line is 180 degrees and c is 60 then f will be 180-60 which is 120.
120 degree is the same as the sum of a and b, so we could write:
a + b = f
Hence, the relationship between angles f, b, and a could be as a + b = f.

Student Council held a bake sale to raise money for the local food pantry. They sold a total of 40 items which included pies and cakes. Pies were $10 each and cakes were $8 each. They raised $356. How many pies and how many cakes did they sell?
Answer: 18 pies, 22 cakes
Step-by-step explanation:
Let the number of pies sold be represented by p.
Let the number of cakes be represented by c.
The information in the question can then be represented in an equation as:
p + c = 40 ........ i
10p + 8c = 356 ....... ii
Multiply equation i by 10
Multiply equation ii by 1
10p + 10c = 400 ....... iii
10p + 8c = 356 ....... iv
Subtract iv from iii
2c = 44
c = 44/2
c = 22
22 cakes were sold
Since 40 items were sold, the number of pies sold will be:
= 40 - 22
= 18 pies

1. A green light blinks every 4 seconds and a yellow light blinks every 5 seconds. When will both lights blink at the same time?
:
2. A red light blinks every 12 seconds and a blue light blinks every 9 seconds. When will both lights blink at the same time?
:
3. Explain how to determine when 2 lights blink together.
:
Answer:
1) both lights will blink at the same time every 20 seconds
2)Both lights will blink at the same time every 36 seconds
3) How to determine when 2 lights will blink together is that you must find the least common factor (LCM) of both numbers and when both hit the same number then that is when both lights blink at the same time.
Step-by-step explanation:
For example for number 1 we have 4 and 5 seconds when the lights blink
4: 4, 8, 12, 16, 20...
5: 5, 10, 15, 20...
we see that the LCM factor is 20 and that is when both lights will hit at the same time.
