<span>12*(4x−5)/52=10 if this is the equation
the value for x would be
x </span>≈ 12
Answer:
A≈967.61
Step-by-step explanation:
Step-by-step explanation:
step 1. (-0.4)(0.16) = -0.064
step 2. (0.625)(-0.08) = -0.05
step 3. -1.2(-5.1) = -6.12
Let 2x – y = 3 ——— equation 1
Let x + 5y = 14 ——— equation 2
Making x the subject in eqn 1, = x = y + 3 / 2 ——— eqn 3
• Put eqn 3 in eqn 2
(y + 3 / 2) + 5y = 14
6y = 14 – 3/2
6y = 25/2
y = 25/12
• put y = 25/12 in eqn 3
x = (25/12 + 3/2)
x = 43/12
Answer:
-3
Step-by-step explanation:
f(x)=-2x+7
f(5)=-2×5+7
=-10+7
=-3
