47 - 19 = 28
28/4 = 7
At most they can spend 7 hours
The solution is
T = (47-19)/4
T = 28/4
T = 7
I think that solution is what your teacher is asking for, i'm not certain but ik the answer should be 7 hours.
Answer:
<em><u>x = 249</u></em>
Step-by-step explanation:
Step 1. Combine like terms
1/3x + 166 = x
Step 2. Subtract 1/3x from both sides
166 = 2/3x
Step 3. Multiply it all by 3/2 to get rid of the 2/3
249 = X
<span>2x^2 − 2z^4 + y^2 − x^2 + z^4
</span>2(-4)^2 − 2(2)^4 + (3)^2 − (-4)^2 + (2)^4
2(16) - 2(16) + 9 - 16 + 16
32 - 32 + 9 - 16 + 16
answer is 9
The two triangles are similar so you can set up a proportion remember to keep the proportional sides on the same fraction 8 goes with 5 and x with 3
Here is the proportion:
8/5 = x/3
24 = 5x - Cross multiply
24/5 = 4.8 = x - Divide both sides by 5
The option that expresses the age of tree in scientific notation with the lowest level of precision would be A. 3 X 10 to the 3rd power. As it contains the fewest number of significant figures.
