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:
3
Step-by-step explanation:
Well the square root of 12 is 3.464 and 12 squared is 144, and an intiger is a whole number no decimal or fraction. So round 3.464 to the nearest whole is 3. Hope this helps(:

Answer: blue= 93.625
Step-by-step explanation:
Let the red ball be y
Four times of red is 4y
And blue is seven times of red which means 7(4y)
4y+7(4y)=107
Open the bracket
4y+28y=107
32y=107
y=107/32
Make y the subject of formula
y=3.34
Therefore,blue is
7(4(3.34))
Blue= 93.625
