Answer:

21 * 2 = 42

21 + 2 = 23

Step-by-step explanation:

well I know that 6 * 7 = 42 so I’m assuming that’s correct

Then 11 + 12 = 23 it could be the answer I’m not positive for this one though.

The first one should be correct.

Maybe try

21 * 2 = 42

21 + 2 = 23

6/x = 36/54 (what is x)

rodikova [14]

Well, you just need to cross multiply. You would multiply 6 by 54 and x by 36. (324, 36x) Then you would divide 324 by 36 to find x. This would get you x = 9.

What is the answer to x+2 3x-14

Mila [183]

Answer:

If your asking for x, the answer would be 8

Step-by-step explanation:

3 times 8 would be 24

24 minus 14 would be 10

and 8 plus 2 =10

10 = 10 there for x=8

Whats 2/3x+3/7=1-4/7x

Juliette [100K]

Answer:

$x=6/13$

Step-by-step explanation:

So we have:

$\frac{2}{3}x+\frac{3}{7}=1-\frac{4}{7}x$

Remove all the fractions to make things simpler. To do so, we can multiply by the LCM of the denominators.

The denominators are 3 and 7.

The LCM of 3 and 7 is 21. Thus, multiply everything by 21:

$21(\frac{2}{3}x+\frac{3}{7})=21(1-\frac{4}{7}x)$

Distribute:

$\frac{42}{3}x+\frac{63}{7}=21-\frac{84}{7}x$

Simplify the fractions:

$14x+9=21-12x$

Add 12x to both sides:

$26x+9=21$

Subtract 9 from both sides:

$26x=12$

Divide both sides by 26:

$x=12/26$

Reduce:

$x=6/13$

And that's our answer :)

Given that Ray B A bisects ∠DBC, which statement must be true? m∠ABD = m∠ABC AB ≅ BC B is the midpoint of DC. m∠DBC = 90°

nadya68 [22]

Answer:

A. $m\angle ABD=m\angle ABC$

Step-by-step explanation:

We are given that a ray BA bisects angle DBC.

We have to find true statement .

Angle bisector property:When a ray bisect any angle then the angles made by bisection of angle are equal.

When ray BA bisects angle DBC

Then, $m\angle ABD=m\angle ABC$

By angle bisector property.

Therefore, option A is true.

Answer:A. $m\angle ABD=m\angle ABC$
