Answer:
THAT IS
3X+11
Find the numbers
HENCE 2X+8=3X+11
3X-2X=8-11=-3
X=-3
SO THE 2 NUMBERS ARE -3 AND -3+4=1..THAT IS -3 AND 1
Step-by-step explanation:

Answer:
missing side length is 12
Step-by-step explanation:
similar means that all correlating pairs of sides have the same ratio (old side length) / (new side length).
so, when we know the ratio of one pair, we can apply it to any other side to calculate the correlating side.
we see, when we go from small to large, that we have the ratio 32/40 = 4/5.
so, multiplying the larger side by this, we get the shorter side.
15 × 4/5 = 3 × 4 = 12
the proportion part in your picture is a bit confusing :
yes,
x/15 = 32/40 = 32/40
I don't know, why this last expression was repeated.
x/15 = 32/40
x = 15×32/40 = 15×4/5 = 3×4 = 12
as you see we get of course the same result doing it that way.
Answer:
The volume of the marble is 47 ml
The volume of the water is 100 ml
Step-by-step explanation:
we know that
The volume of the marble is equal to the change in water level
so
To find out the volume of the marble subtract 100 ml from 147 ml
The volume of the water no change
The volume of the water is 100 ml
-12x-20-40plus 16x
-4x plus -60
