Let the unknown number be x. Then (1/10)x = 0.002. To solve for x, multiply both sides by 1000 to remove the decimal fraction 0.002.
Then 1000(1/10)x = 1000(0.002), or 100x = 2. Dividing both sides by x returns
x=100/2, or x= 50 (answer)
Answer:
d
Step-by-step explanation:
A segment joining the midpoints of a triangle is
• Parallel to the third side
• Half the length of the third side
The segment DF joins the midpoints of 2 sides of Δ ABC , then
BC = 2 × DF = 2 × 4 = 8
Answer:
f(x)= -2(x^2-x-6)
Step-by-step
The original formula is f(x)=a(x-h)+k
1) Plug the negative 2 in for a
2) multiply (x-3)(x+2)
3) plug your answer in for 2 in for the parentheses
Answer:
x = 20
Step-by-step explanation:
x^2 - 4x - 8 = 8
x^2 - 4x - 8 + 8 = 8 + 8
x^2 - 4x = 16
x (x - 4) = 16
x - 4 = 16
x - 4 + 4 = 16 + 4
x = 20
20+x = 12+2x is the answer and x=8
