The ratio of damaged to undamaged toys was 3/17. If there were a total of 200 toys, how manywere undamaged?

Answers

Answer:

What I would do is find how many undamaged toys per 1 toy and then times that by 200.

Step-by-step explanation:

okay, so basically it’s the ratio of damaged to undamaged toys. which means that damaged is ‘3’ and undamaged is ‘17’. what i would do, is that i would:

17+3=20

200/20=10

so, ‘1’ refers to 10 toys. therefore we multiply the amount of undamaged toys by 10 which would get u the answer

10x17=170

which, equals to 170 undamaged toys.

i hope this helped u :)

Solve equation 19 - h - h = -13

Answers

Answer:

h = 16

Step-by-step explanation:

to solve this equation

we are going to take cognizance of the positive and negative sign as any misinterpretation of the sign might influence our answer wrongly. Note this

negative × negative = positive

positive × negative = negative

negative × positive = negative

positive × positive = positive

so, from the question 19 - h - h = -13

19 - h - h = -13

19 -2h = -13

collect the like terms

19 + 13 = 2h

32 = 2h

divide both sides by the coefficient of h which is 2

32/2 = 2h/2

16 = h

therefore h = 16
