12/15 = 8/x
Cross multiply:
12*x = 8*15
⇒ 12*x= 120
⇒ (12/12)*x = 120/12
⇒ x= 10.
Final answer: x=10.
Hope this helps~

Hello!
To the value of b, or the y-intercept, we need to substitute an ordered pair/point into the given equation.
Since we are given two points, we can use those two points to find two different equations.
Remember that ordered pairs are written as (x, y).
A(-2, 4)
y = -3x + b
4 = -3(-2) + b
4 = 6 + b (subtract 6 from both sides)
-2 = b
A) Therefore, the equation of the first ordered pair is y = -3x - 2.
B(5, 2)
2 = -3(5) + b
2 = -15 + b (add 15 to both sides)
17 = b
B) The equation of the second ordered pair is y= -3x + 17.
<u>Final answers</u>:
- A) y = -3x - 2
- B) y = -3x + 17
A quarter is either:
A. 1/4
B. 25 cents
if it is 1/4 then
9 quartrers is 9 times 1/4=9/4=2 and 1/4
if it is 25 cents then
0.25 dollars times 9=$2.25
Answer:
x=-2 y=3
Step-by-step explanation:
you should multiple second equation by -5 and collect all terms then put -2 from x
