Hello from MrBillDoesMath!
Answer:
x = 19
Discussion:
Both sides are logarithms to the same base, namely 20
, which implies the expressions in x (what we are taking logarithms of) must be equal. So we need to solve
4x - 10 = 3x + 9 => subtract 3x from both sides
4x-3x - 10 = 9 => add 10 to both sides
x = 9 + 10 = 19
Thank you,
MrB
Answer:i THINK 79, i dont know fully, but i think 79
Let
x--------> the number of gray bricks
y--------> the number of red bricks
we know that
------> inequality 1
<em>-----> </em>inequality 2
therefore
<u>the answer is</u>
x > 0
0.45x+0.58y≤200
Plug in the points and see if y and x are equal to each other.
(2,3)
y= x-1
3= 2-1
3= 1 (not the solution)
y=3x
3=3*3
3=9 (not the solution)
y=x+1
3=2+1
3=3 (solution) We can check to make sure.
y=-3x
3=-3*3
3=-9 (not the solution)
y=x+1 <em>is the answer.
</em>
I hope this helps!

Answer: x = 5.625
Step-by-step explanation: The triangles are similar; the side lengths of the large triangle are proportional to the lengths of the small triangle. The corresponding parts are proportional.
Use proportion. The total length of side FV is 16.
6:16 = x:15 . or 6/16=x/15
cross multiply 15 × 6 = 90, then divide 90/16
90/16 = x
5.625 = x
