The sum of a number and 5 is tripled then lessened by 15 to get 9

x = "a number"

:

Just write an expression for each phrase:

:

"sum of a number & 5 is tripled",

3(x+5)

:

"the result"

=

:

"1 less than twice the number"  

2x - 1

:

Put is all together to form an equation and solve it:

3(x+5) = 2x - 1

:

3x + 15 = 2x - 1

:

3x - 2x = -1 - 15

:

x = -16

:

:

Now in the original statement see if that is true

"the sum of a number and five is tripled, the result is one less than twice the number"

3(-16+5) = 2(-16) - 1

3(-11) = -32 - 1

-33 = -33; equality confirms our solution of x = -16

< 4, -5>

step-by-step explanation:

starting from g. we move 4 right and then 5 down to get to h. that means the vector is < 4, -5>
