Answer:

4

Step-by-step explanation:

3r= 10 +5s

r=10 -->  3r= 30

30r=10 =5s

Subtract 10 from both sides

20r=5s

Divide by 5

S=4

A. 4

if r = 10 then that will be 30 because it’s 3 r meaning 3 times whatever r is (10 in this case)
and if 10 plus 5s is equivalent to 3 r which is 30, s will have to be 4 because 5 times 4 is 20 and 20 plus 10 is 30.

Table C is the correct values of the relationship.

Solution:

To find which table of values shows the relationship between the number of cakes the baker makes and the number of bags of flour uses:

Table A: Ratio of cakes baked to bags of flour used

\frac{9}{4} , \frac{18}{6}=\frac{3}{1} and \frac{27}{9}=\frac{3}{1}

Here the ratios are not same.

So, this table is not true.

Table B: Ratio of cakes baked to bags of flour used

\frac{6}{2}=\frac{3}{1} , \frac{12}{4}=\frac{3}{1} and \frac{18}{6}=\frac{3}{1}

Here the ratios are same.

So, this table is true.

Table C: Ratio of cakes baked to bags of flour used

\frac{4}{9} , \frac{6}{18}=\frac{1}{3} and \frac{9}{17}

Here the ratios are not same.

So, this table is not true.

Table D: In this table cakes baked is 6 and the bags of flour is 18.

But a baker made 18 cakes using 6 bags of flour.

So, this table is not true.

Hence table C is the correct values of relationship.
