Step-by-step explanation:

3) y=4x-2

since x is already 3, simply substitute

y= 4(3)-2

y=12-2

y=10

second pair for number 3 is 10

4) y=16+7x

since y is already 37, simply substitute

37=16+7x

37-16=7x

21=7x

x=21/7

x=3

second pair for number 4 is 3

If 3/p = 6 and 3/q = 15 then p - q =?

Sphinxa [80]

Answer:

0.3 or 3/10

Step-by-step explanation:

If $\frac{3}{p}$ = 6, then p must be 0.5 (since 3/[1/2] is also 3x2).

If $\frac{3}{q}$ = 15, then q must be 0.2 (since 3/[1/5] is also 3x5).

p - q would be 0.5 - 0.2, which means the final answer is 0.3 (3/10).

What is the solution to the equation 2n/3 = n+14/5

Firdavs [7]

Answer: $n=-\frac{42}{5}$

Step-by-step explanation:

1. You have the following equation given in the problem above:

$\frac{2n}{3}=n+\frac{14}{5}$

2. You must solve for n, as following:

$\frac{2n}{3}=n+\frac{14}{5}\\\frac{2n}{3}-n=\frac{14}{5}\\\frac{2n-3n}{3}=\frac{14}{5}\\\frac{-n}{3}=\frac{14}{5}\\-n=\frac{3*14}{5}\\-n=\frac{42}{5}\\n=-\frac{42}{5}$

3. Then, the result of the equation is:

$n=-\frac{42}{5}$
