If the measure of DAC is x and the measure of CAB is (2x – 30), what is the value of x? (HINT** remember how we label angles, th

Scorpion4ik [409]

Answer:

Step-by-step explanation:

∠ BAD = 90° and

∠ DAC + ∠ CAB = ∠ BAD, that is

x + 2x - 30 = 90

3x - 30 = 90 ( add 30 to both sides )

3x = 120 ( divide both sides by 3 )

x = 40 → b

Which explanation correctly tells whether these ratios are equivalent and why?

Reptile [31]

<h3><u>Answer:</u></h3>

<u>Option A (Yes because 3 x 2 = 6 and 14 x 2 = 28.) is correct.</u>

<h3><u>Step-by-step explanation:</u></h3>

<u>This is because if we simplify 3/6 and 14/28, both of them will get 1/2. This means that only A and C are possible.</u>

=> Option A is correct because 3 x 2 does equal 6 and 14 x 2 does equal 28.
=> Option C is incorrect because 3 x 5 does not equal 14 and 6 x 5 does not equal 28.

Find The Value Of x ?

slega [8]

<u>Answer</u>:

1) $x = -1$ || 2) $x = 10$

<u>Explanation</u>:

→ $\log _3\left(\frac{1}{3}\right)=x$

→ $\frac{1}{3} = 3^x$

→ $3^{-1} = 3^x$

→ $x = -1$

→ $\log _3\left(x-1\right)=2$

→ $x - 1 = 3^2$

→ $x -1 = 9$

→ $x = 9 +1$

→ $x = 10$

Find the value of "a" if you knew the perimeter was 47 meters long. Here is the experssion 7a-2

Aneli [31]

That isn’t right I don’t think, if a was 47 then it would be wayyyy bigger of a number. You are finding how 7a-2 is 47. First add 2 to both sides making it 7a=49
7 times what is 49?
That is a
