-40-10x (I think, sry if it’s wrong)
You can convert between the various different sizes by merely moving the decimal point the correct number of places. The basic metric units are meters (for length), grams (for mass or weight), and liters (for volume).
Answer:
(-1,0)
Step-by-step explanation:
Here, our interest lies in finding the coordinates that splits the points (-5,-8) and (2,6) in the ratio 4:3. Let the point that does the splitting be called point P
The section formula is used here and the point we are having would be;
P = (mx2 + nx1)/(m+n) , (my2 + ny1)/(m + n)
From the question;
m = 4 and n = 3
x1 = -5, y1 = -8
x2 = 2 , y2 = 6
Plugging these values in the equation above, we have;
P = [4(2) + 3(-15)](3+4), [4(6) + 3(-8)]/(3+4)
P = (8-15)/7, (24-24)/7
= -7/7, 0/7
= (-1, 0)
The coordinates of point P is (-1,0)

1 gallon of water requires 3/4 teaspoon of plant food, so multiply 3/4 by 5
3/4 × 5
Make 5 into a fraction
3/4 × 5/1
Multiply the denominator by the denominator and the numerator by the numerator
3 × 5 15

15/4 is an improper fraction, so make it a mixed fraction
15/4 = 3 and 3/4
Answer:
Pedro should mix 15/4 teaspoons or 3 and 3/4 teaspoons of plant food into 5 gallons of water.</span>
Answer:
The inequality is not true
Step-by-step explanation:
we have
![-2(2x+9)> -4x+9](https://tex.z-dn.net/?f=-2%282x%2B9%29%3E%20-4x%2B9)
Distributed left side
![-4x-18 > -4x+9](https://tex.z-dn.net/?f=-4x-18%20%3E%20-4x%2B9)
Adds 4x both sides
----> is not true
