Bryce has $16 more than Corey. Both have a combined total of $50. How much money does Bryce have.
LekaFEV [45]

Answer:

$33

Step-by-step explanation:

Let the amount of money Corey has be $x.

Amount of money Bryce have= $(x +16)

Total amount= $50

$x +$(x +16)= $50

2x +16= 50

2x= 50 -16

2x= 34

Divide both sides by 2:

x= 34 ÷2

x= 17

Amount of money Bryce have

= $(17 +16)

= $33

Identify which lines are parallel.<br> y=2;y=x+2;y=2x-1;y=2x+1
Ne4ueva [31]

Answer:

y=2

Step-by-step explanation:

A parallel line are lines that never intersect.

-They are generally formed when a line when lines are perfectly horizontal to the x axis or the vertical to the y-axis.

=>y=2 is the only parallel line .

=>y=x+2 is not parallel as the (x+2) is not a constant

=>y=2x-1 is not parallel as the (2x-1) is not a constant

=>y=2x+1 is not parallel as the (2x+1) is not a constant

A. 16 is divisible by 2 but not divisible by 3
B. 23 is not divisible neither by 2 nor 3
C. 27 is not divisible by 2, however it's divisible by 3
D. 36 is divisible both by 2 and 3

So the only number we can focus on is 36:

Solve the expression 7^P 2 (P = permutation)
Keith_Richards [23]

Answer:

42

Step-by-step explanation:

_aP_b = \dfrac{a!}{(a - b)!}

_7P_2 = \dfrac{7!}{(7 - 2)!}

_7P_2 = \dfrac{7 \times 6 \times 5!}{5!}

_7P_2 = 7 \times 6

_7P_2 = 42

What is the property and how are the exponents combined?
saul85 [17]

Answer:

x^15

Step-by-step explanation:

x^3 * x^2  (x^3)^2 x^6

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

x^2

First I will use the power of powers  x^a^b = x^(a*b)

x^3 * x^2  x^(3*2) x^6

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

x^2

x^3 * x^2  x^(6) x^6

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

x^2

Next we will use the multiplication rule x^a * x^b = x^(a+b)

x^(3 +2+6+6)

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

x^2

x^(17)

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

x^2

Next we will use quotient rule  x^a / x^b = x^(a-b)

x^(17 -2)

x^15
