Answer:
She can make up to 5 groups.
Step-by-step explanation:
We have to find the first divisible number that are divisble for each 20 and 25.
Divisible numbers of 25: 1, 5 Divisible numbers of 20: 1,4, 5, 10
Therefore 5 is the answer. GIMME BRAINLIEST PLS AND THANKS xD
The integers are 12, 14.
Solution:
Let the even consecutive integers be x and x + 2.
Lesser number = x and Greater number = x + 2
Lesser number = Half of greater number + 5


To add the numbers, denominators must be same. So multiply 5 by
.


Multiply by 2 on both sides, we get
⇒ 2x = x + 12
Subtract x from both sides.
⇒ x = 12
Lesser number = 12
Greater number = 12 + 2 = 14
Hence the integers are 12, 14.
Answer: x=-2
Step-by-step explanation:
Perimeter can be found by the formula : Perimeter = 2L + 2 W
Perimeter = 2L + 2 W
Perimeter = 2(2a) + 2(a + 1) . ← Option 4
Perimeter = 4a + 2a + 2
Perimeterr = 6a + 2 ← Option 5
Perimeter can also be found by simply adding up all the 4 sides:
Perimeter = L + W + L + W
Perimeter = L + W + L + W
Perimeter = 2a + a + 1 + 2a + a + 1 ← Option 3
Perimeter = 3a + 1 + 3a + 1 ← Option 1
Answer: Option 1, 3, 4 and 5 are correct.
