Answer:
The value of x is 200 in the equation 1/5x - 2/3y = 30, when y = 15
Step-by-step explanation:
<u>Given</u>
equation: x - 2/3y = 30
when y = 15
<em>Plug in y:</em>
1/5x - 2/3(15) = 30
1/5x - 10 = 30
<em>add</em> 10 to both sides,
1/5x - 10 + 10 = 30 + 10
1/5x = 40
<em>multiply</em> both sides by 5
1/5x * 5= 40 * 5
x = 200
Answer:
2/21x7/5 is 14/105
Step-by-step explanation:
Answer:
Step-by-step explanation:
m = 4 ; (1,-2)
y - y₁ = m (x - x₁)
y - [-2] = 4 (x - 1)
y + 2 = 4x - 4
y = 4x - 4 - 2
y = 4x - 6
