Answer:
The value of x is 24
Step-by-step explanation:
To find this, create a proportion using each triangle. Use the base as the top and the side as the bottom.
56/35 = 44.8/(x + 4)
56(x + 4) = 44.8*35
56x + 224 = 1568
56x = 1344
x = 24
Answer:
7:2
Step-by-step explanation:
Answer:
x = 2
Step-by-step explanation:
<em><u>1. Combine multiplied terms into a single fraction</u></em>
<em><u>19.2 − 15 = 7.5 + 8.4</u></em>
<em><u>96/5 − 15 = 7.5x + 8.4</u></em>
<u><em></em></u>
<u><em>2. Combine multiplied terms into a single fraction again</em></u>
<em><u>96/5 − 15 = 7.5x + 8.4</u></em>
<em><u>96/5 − 15 = 15x/2 + 8.4 </u></em>
<em><u /></em>
<em><u>3. Add 15 to both sides of the equation</u></em>
<u><em>96/5 − 15 = 15x/2 + 8.4 </em></u>
<u><em>96/5 − 15 + 15 = 15x/2 + 8.4 + 15</em></u>
<u><em /></u>
<u><em>4. Simplify</em></u>
- <u><em>Add the numbers</em></u>
<em> </em><u><em>96/5 = 15x/2 + 8.4 +1.5</em></u>
- <u><em>Add the numbers again</em></u>
<em> </em><u><em>96/5 = 15x/2 + 23.4</em></u>
<u><em /></u>
<u><em>5. Multiply all terms by the same value to eliminate fraction denominators</em></u>
<u><em>96/5 = 15x/2 + 23.4</em></u>
<u><em>2 x 5 x 96/5 = 2 x 5(15x/2 + 23.4)</em></u>
<u><em>7. solution</em></u>
<u><em>x=2</em></u>

Answer:
40 ft
Step-by-step explanation:
The post is 8/12 = 2/3 as tall as the shadow is long. We expect the same relationship holds for the tree.
tree height = (2/3)(shadow length) = (2/3)(60 ft) = 40 ft
The tree is 40 feet tall.
The answer for this is False
