PLEASE ANSWER FAST! Find BDC. BDC=​ - 1

Answers

Answer 1
Answer:

Step-by-step explanation:

<NDC=<NCD (Given)

<NCD=35°.

<CAN=<DBN (Given)

<DBN=50°.

therefore, <CND = 180-35-35=110.

and <CND and <DNB are linear pair.

<CND+<DNB=180°

<DNB=180-110

<DNB=70.

therefore, <BDN = 180-50-70 = 60.

therefore, <BDC= 35°+60°=95°.

hope this helps you.

Four children have small toys. The first child has 1/10 of the toys, the second child has 12 more toys than the first, the third child has one more toy of what the first child has and the fourth child has double the third child. How many toys are there?

Answers

Call x the amount of toys the first child has.We write the equation x+(x+12)+(x+1)+2(x+1)=10x.This is equal to 5x+15=10x. Subtracting 5x, we see that 5x=15, so x=3. There are 10x toys, so we have 3*10=30 total toys.

C/d+2=f/g solve for c

Answers

So if you want to solve for c, the best thing to do is isolate the variable. So I personally don't enjoy dealing with fractions that much until the very end, so I am going to multiple the entire equation by d*g to eliminate the fraction. So now the equation is cg+2dg=fd. In order to isolate the c variable, subtract both sides by 2dg, which makes it cg=fd-2dg. Now divide both sides by g, c=(fd-2dg)/(g). So that's what c equals in terms of f, d and g.

Two equivalent rational numbers of -13/9

Answers

Hello!

Answer:

\Large \boxed{\sf -(26)/(18)~~ and~ -(52)/(36) }

Step-by-step explanation:

→ We want two equivalent rational numbers of -13/9.

→ Let's convert the fraction -13/9:

\sf -(13)/(9) = -(13* 2 )/(9* 2) = \boxed{\sf -(26)/(18) } = -(26* 2)/(18* 2) = \boxed{\sf -(52)/(36) }

Conclusion:

-13/9 is equal to -26/18 which is equal to -52/36.

Answer:

-26/18 and -39/27

Step-by-step explanation:

-13/9 x 2/2 = -26/18

-13/9 x 3/3 = -39/27
