The first numbers is 7 more than the second. their sum is 29. find the answers

If the first number is x and y is the second number

x = 11

y = 18

Step-by-step explanation:

If x is the first number and y is the second number then:

x + 7 = y

The sum of the two numbers is expressed as:

x + y = 29

In order to find what the two numbers are, use what you know. According to the first equation, y equals the first number(x) plus 7, so you can substitute that for the y in the second equation

x + y = 29

x + (x + 7) = 29

2x + 7 = 29

2x + 7 - 7 = 29 - 7

2x/2 = 22/2

That means x equals 11

Now that x is known, you can find the value for y. The second number(y) is 7 more than than the first number(x) so that means x + 7 = y

11 + 7 = y

y = 18

3,6 and 7.

step-by-step explanation:

a) unit place of 37 is 7

so the unit place of cube of 37 will be

7³= 343=3

the answer is 3.

b) unit place of 56 is 6, so the unit place of cube of 56 will be

6³= 216=6

the answer is 6.

c) unit place of 133 is 3, so the unit place of cube of 133 will be

3³= 27= 7.

the answer is 7.
