Answer:

  6.36 m

Step-by-step explanation:

The length of the tree's shadow is 7 m + 1.8 m = 8.8 m. Tanya's height is 1.3/1.8 times the length of her shadow. The tree height is, likewise, 1.3/1.8 times the length of its shadow, so is ...

  tree height = (1.3/1.8)×(8.8 m) ≈ 6.36 m

The tree is about 6.36 m tall.

<u>1 + 4x = -5 + 7x</u>

1st step: you need to move 4x to the right and -5 to the left so that all the x's are in one place. 4x will be negative and -5 will be positive when you move them. So it will be:

1+5=7x-4x

2nd step:

3x=6

3rd step: you need to divide both sides into 3, because it is the common divisor.

x=2

<h2>To sum up:</h2>

<em>1 + 4x = -5+7x</em>

<em>7x - 4x = 1 + 5</em>

<em>3x = 6</em>

<h2><em>x = 2</em></h2>

You can try to memorize the summary. However, it is better to understand the solution as a whole.

8. The total weight of a vase and its packaging is: 4 lb. 7 oz. The vase by itself
scoray [572]

Answer:

E

Step-by-step explanation:

the weight of the packaging materials is 12 oz. There are 16 oz in a pound. If the vase weighs 3 lb 11 oz, it would take 5 more oz to reach the next pound, and there was another 7 oz after that. You would then do 5 + 7, which is 12, so the packaging materials weigh 12 oz.
