Answer:

n=0.4

Step-by-step explanation:

10:4=5:2

to make 5 as 1, we will divide both 5 and 2 by 5

<h3>\frac{5}{5}:\frac{2}{5}=1:n</h3><h3>therefore, n=\frac{2}{5} = 0.4</h3><h3 /><h3>                                           </h3>

Can some one help me. Solve this equation.
Marina86 [1]

\bold{Given : 2^2^x^-^2 - 2^x^-^1 = 2^x - 2}

\bold{\implies (2^2^x) (2^-^2) - (2^x)(2^-^1) = 2^x - 2}

\bold{\implies \frac{(2^2^x)}{(2^2)} - \frac{(2^x)}{(2^1)} = 2^x - 2}

\bold{\implies \frac{(2^2^x)}{4} - \frac{(2^x)}{2} = 2^x - 2}

\bold{\implies \frac{[2^2^x - (2^x)(2)]}{4} = 2^x - 2}

\bold{\implies [2^2^x - (2^x)(2)] = (4)(2^x) - 8}

\bold{\implies 2^2^x - (2^x)(2) - (4)(2^x) + 8 = 0}

\bold{\implies (2^x)^2 - (2^x)(6) + 8 = 0}

\bold{Let\;us\;take : (2^x) = Z}

\bold{\implies Z^2 - 6Z + 8 = 0}

\bold{\implies Z^2 - 4Z - 2Z + 8 = 0}

\bold{\implies Z(Z - 4) - 2(Z - 4) = 0}

\bold{\implies Z = 4\;\;(or)\;\;Z = 2}

\bold{But : Z = 2^x}

\bold{\implies 2^x = 4\;\; (or) \;\; 2^x = 2}

\bold{\implies 2^x = 2^2\;\; (or) \;\; 2^x = 2^1}

\bold{\implies x = 2\;\;(or)\;\; x = 1}

Given that MTW = CAD, which segments are corresponding parts of the congruent triangles?
VikaD [51]

Answer: MW = CD

Explanation: It would be this way because if you wrote the triangles out, MW would be in the same place as CD, making them corresponding.

Please help!<br> "Congruence and Constructions".
marin [14]

Answer:

MNK = TRP

MN is congruent to TR.

X = 6.3

Step-by-step explanation:

MNK is congruent to TRP because the two triangles are congruent, which is a given statement. This also means that all side and angle measures will be congruent. Because of this, it can be inferred that MN is congruent to TR and they have equal side length measures. This means that TR measures 20. This means that 3X - 1 = 20. By solving we can get 6.33.
