Answer:

Step-by-step explanation:

1. x + 5.3 = 10.1

combine the like terms

x = 10.1 - 5.3

x = 4.8

2. x - 4.2 = 12.9

combine the like terms

x = 12.9 + 4.2

x = 17.1

3. 1.5x = 60

divide both sides by 1.5

x = 60/1.5

x = 40

4. x/1.3 = 1.8

cross multiply

1.3 goes to 1.8 and x stands alone

x = 2.34

Hope this helps

Explain in words how to find -4 times -1.5 on a number line in words

borishaifa [10]

Since both numbers are negative we know that the product will be positive and when something is time 1.5 that is the same as a 50% increase so that is adding half of the original number (4) so the final answer is 6 (4+(half of 4))=6

A kite is stuck in a 36-ft tree. If the angle of elevation from the kite and the ground is 12, find the length of the kite.

yanalaym [24]

Answer:

173.15 ft.

Step-by-step explanation:

Please find the attachment.

Let L be the length of kite.

We have been given that a kite is stuck in 36-ft tree. The angle of elevation from the kite and the ground is 12.

We can see from our attachment that kite and tree form a right triangle. height of tree is opposite of angle of elevation and length of kite is hypotenuse.

Since we know that Sine relates the opposite and hypotenuse of a right triangle, so we will use sine to find the length of kite.

$sin(12)=\frac{36}{L}$
