Question 1: The sum of two consecutive even integers is 70. Find the numbers. Question 1 options:

zloy xaker [14]

Question (1):
Assume that the first number is n. Since the two number are consecutive even numbers, this means that the second number is n + 2
We know that the sum of the two numbers is 70. This means that:
n + n + 2 = 70
2n + 2 = 70
2n = 68
n = 68/2
n = 34
This means that the two numbers are: 34 and 34+2 = 36 .......> last option

Question (2):
Assume dog's age is x. We know that cat's age is 5 less than twice dog's age. This means that:
cat's age = 2x - 5
We know that cat's age is 11, therefore:
11 = 2x - 5
11 + 5 = 2x
16 = 2x
x = 16/2 = 8
Dog's age is 8 .......> first option

Question (3):
The three numbers are consecutive. This means that we can assume the numbers to be n, n+1 and n+2. We know that their sum is 46. Therefore:
n + n + 1 + n + 2 = 46
3n + 3 = 46
3n = 43
n = 43/3
The three numbers are 43/3 , 46/3 and 49/3 .......> none of the given options in correct

Question (4):
The three consecutive numbers are all even. This means that we can assume the numbers to be n , n+2 and n+4
We know that their sum is 198. This means that:
n+n+2+n+4 = 198 .........> second option

Question (5):
The four consecutive numbers can be assumed as n, n+1 , n+2 and n+3. We know that their sum is 86. Therefore:
n + n+1 + n+2 + n+3 = 86 .......> third option

Question (6):
Assume the width is w. We know that the length is 15 cm greater than the width. This means that:
length = w + 15
Now, we have:
perimeter = 2(length + width)
150 = 2 (15 + w + w)
75 = 15 + 2w
60 = 2w
w = 60/2
w = 30 cm
This means that:
length = 15 _ 30 = 45 cm
Based on the above, the dimensions of the rectangle are:
length = 45 cm and width = 30 cm .......> first option

Question (7):
Assume original price before taxes is x
Total price = original price + taxes
825 = x + 0.1x = 1.1 x
x = 825/1.1
x = $750 .........> second option

Question (8):
Assume cost of helmet is x and that cost of bicycle is 5x. We know that the total is 240. This means that:
240 = x + 5x = 6x
x = 240/6
x = 40
This means that:
price of helmet = $40
price of bicycle = 5(40) = $200
..........> first option

Hope this helps :)

Write the sum of the numbers as the product of their GCF and another sum. Show your work. Can you guys help me please and explai

Gre4nikov [31]

The distributive property: a(b + c) = ab + ac

-------------------------------------------------------------------

Factors of 56: 1, 2, 4, 7, 8, 14, 28, 56

Factors of 64: 1, 2, 4, 8, 16, 32, 64

GCF(56, 64) = 8

56 = 8 · 7

64 = 8 · 8

56 + 64 = 8 · 7 + 8 · 8 = = 8(7 + 8)

--------------------------------------------------------------------

Factors of 30: 1, 2, 3, 5, 6, 10, 15, 30

Factors of 54: 1, 2, 3, 6, 9, 18, 27, 54

GCF(30, 54) = 6

30 = 6 · 5

54 = 6 · 9

30 + 54 = 6 · 5 + 6 · 9 = 6(5 + 9)

Answer:

You have the right answer selected (139°)

Step-by-step explanation:

Similar means that their angles are the same.

77 + 62 = 139

You have to add 180, but then you have to subtract it.
