Answer:
4 kg
Step-by-step explanation:
so 1.6 * 4 is 6.4 so you just double check if you want
4 + 1.6 which is 1/4 of 6.4 will be 5.6 (matches with the question)
4 + (1.6*4) (indicates it's full) = 10.4( also Matches with the question)
there is another way by setting up an equation. let me know in comments if you want to see it that way
The height of Ernies shadow is 4 feet when his height is 6 feet.
<h3>
equation</h3>
An equation is an expression used to show the relationship between two or more variables and numbers.
Let x represent the length of his shadow. Given that the ratio of ernie's height to his shadow's height is 1.5 to 1. Hence:
- (1.5/2.5) * y = 6
- y = 10 feet
(1/2.5) * 10 = x
x = 4 feet
The height of Ernies shadow is 4 feet when his height is 6 feet.

Opposite sides in a parallelogram are equal
So,
XY=WZ
3a-4=a+2
2a=6
a=3
XW=YZ
b+1=2b
b=1
Answer:
Step-by-step explanation:
C11 = (1×1) + (-1×3) = 1-3 = -2
C12 = (1×2) + (-1×4) = 2-4 = -2
C21 = (2×1) + (1×3) = 2+3 = 5
C22 = (2×2) + (1×4) = 4+4 = 8
I think the simplify expression is 2^2 x 7 = 28. Sorry if it is wrong
