You would cross multiply for this. So 8.4/6 = x/14 to get 6x=117.6 Now you divide 117.6 by 6 to get your final answer 19.6
So x equals 19.6
The relationship between y and x is y = 5x + 15.
<h3>
Linear equation</h3>
A linear equation is in the form:
y = mx + b
where y, x are the variables, m is the rate of change (slope) and b is the initial value of y (y intercept).
From the table, using point (5, 40) and (25, 140):
The relationship between y and x is y = 5x + 15.

<span>A quarter is equivalent to 25 cents or $0.25 and a nickel is equal to 5 cents or $0.05. In the given in this item, if there are x nickels then, there are x + 7 quarters. With these and the total amount known, we can now compute for the value of x.
(x)(0.05) + (x + 7)(0.25) = 2.65
Simplifying,
0.05x + 0.25x + 1.75 = 2.65
Simplifying further,
0.3x = 0.9
The value of x from the equation is 3. Hence, there are 10 quarters.</span>
Answer:
7
Step-by-step explanation:
BW is 1/3 of the way of JB
like the other question we set up an equation
2x+1=10x+1 but because BW is only one third of the way we have to multiply its side by 3 and the new equation is
9x+3=10x+1
step 1: subtract each side by 9x
3=x+1
step 2; subtract each side by 1
2=x
Next we plug in 2 to x in 3x+1 and get a final answer of
BW = 7
