Answer:   x = 10, y = -1

<u>Step-by-step explanation:</u>

ΔABC ≅ ΔPQR  →  ∠B ≅ ∠Q    and     AB ≅ PQ

      ∠B ≅ ∠Q

12x + 2 = 142 - 2x

<u>+2x       </u>    <u>      + 2x </u>

14x + 2 = 142

<u>        - 2</u>    <u> -2   </u>

14x       = 140

<u>÷14       </u>   <u>÷14  </u>

    x       =  10

   AB ≅ PQ

3y - 1 = 5y + 1

<u>-3y     </u>  <u>-3y      </u>

      -1 = 2y + 1

    <u>  -1 </u>   <u>       -1 </u>

     -2 = 2y

   <u>  ÷2</u>   <u>÷2 </u>

      -1 = y

What is the value of n in this equation: 2↑2 * 2↑n = (2↑4)↑3
Cloud [144]

Answer:

The value of n in the given equation is; n = 10

Step-by-step explanation:

Exponent for a natural power b is defined as iterated multiplication, which Knuth denoted by a single up-arrow:

a↑b = a^b          ......[1]

Given the expression: 2↑2 * 2↑n = (2↑4)↑3

Using [1] in the given expression is;

(2^2) \cdot 2^n = (2^4)^3

Using a^n \cdot a^m = a^{n+m}  and (a^n)^m = a^{nm}

we have;

2^{2+n} = 2^{12}

2 + n = 12                     [ Using a^m = a^n ⇒ m =n ]

Subtract 2 to both sides of an equation:

2 + n - 2 = 12 -2

Simplify:

n = 10

Therefore, the value of n is, 10

It’s the 3rd one because the perpendicular slope of -1/2 would be 2/1 or just 2.

Huxian's father gives her $120 as her monthly allowance. a) If she spends an average of 5 dollars a day, find the amount on mone
abruzzese [7]

Answer:

3 days=  $105, 6 days= $90, 10 days= $70

Step-by-step explanation:

You can rewrite this equation as y=120-5x

x is the amount of days passed

plug in 3 for x and you get 15. 120-15=105

plug in 6 for x and you get 30. 120-30=90

plug in 10 for x you get 50. 120-50=70

Hope this helps!

:)
