Answer:
Choice B & C
Step-by-step explanation:
563 - 192 = 371
The subtraction equals to 371.
100 + 90 + 210 = 400
The answer does not equal to 371 in choice A.
563 - 200 + 8 = 371
The answer equals to 371 in choice B.
571 - 200 = 371.
The answer equals to 371 in choice C.
Answer:
43
Step-by-step explanation:
Let
The unit digit = x
The tens digit = y
The number = 10x + y
The tens digit of a two-digit number is five more than the units digit.
y = x + 5
Seven times the sum of the digits of this number is 3 less than the number itself.
7(x + y) = 10x + y - 3
7x + 7y = 10x + y - 3
Find the number.
We substitute x + 5 for y
7x + 7(x + 5) = 10x + (x + 5) - 3
7x + 7x + 35 = 10x + x + 5x - 3
14x + 35 = 11x + 5x - 3
Collect like terms
35 + 3 = 11x + 5x -14x
38 = 16x - 14x
38 = 2x
x = 38/2
x = 19
Solving for y
y = x + 5
y = 19 + 5
y = 24
The number = 19 + 24
= 43
Answer:
Incorrect/No
Step-by-step explanation:
7x2=14

<u>Follow the below guidelines:</u>
- A positive number times a positive number is a positive number
- A negative number times a positive number is a negative number
- A positive number times a negative number is a negative number
- A negative number times a negative number is a positive number
Looking at the last one, we see that -2x-7=14, a positive number
