Answer:

n = 1.5

Step-by-step explanation:

Given ratio of 1 : n is equivalent to the ratio 4 : 6.

We can rewrite these equivalent ratio as,

\frac{1}{n}=\frac{4}{6}

Now we have to solve this expression for the value of n.

\frac{1}{n}=\frac{2\times 2}{2\times 3}

\frac{1}{n}= \frac{2}{3}

n = \frac{3}{2}

n = 1.5

Therefore, n = 1.5 will be the answer.

15(15b−7)=3b−9 plz help meee
Romashka-Z-Leto [24]

Answer:

B=16over37

Step-by-step explanation:

Step 1: Simplify both sides of the equation.

15(15b−7)=3b−9

(15)(15b)+(15)(−7)=3b+−9(Distribute)

225b+−105=3b+−9

225b−105=3b−9

Step 2: Subtract 3b from both sides.

225b−105−3b=3b−9−3b

222b−105=−9

Step 3: Add 105 to both sides.

222b−105+105=−9+105

222b=96

Step 4: Divide both sides by 222.

222b

222

=

96

222

Then simplify
