The value of x is option B) 6.

<u>Step-by-step explanation:</u>

The given equation is -162=-3+4(6 - 7x).

You can see the bracket on the right of the equation. To remove the bracket, we must use the distributive property.

The distributive property is to multiply the number outside the bracket with each term present inside the bracket.

Here, the number outside the bracket is 4 ans we have to multiply it with 6 and -7x which are inside the bracket.

The simplified form is,

⇒ -162 = -3 + 24 - 28x

Keep x term alone on one side and bring all the constant terms to the other side of the equation.

⇒ -162 = 21 -28x

⇒ 28x = 21+162

⇒ 28x = 183

Divide by 28,

⇒ x = 183/28

⇒ x = 6.5

x can be approximated to 6 which is option B)

Therefore, the value of x is 6.

Mercury:3.3022 x 10^23 Venus:4.8685 x 10^24 Earth: 5.9722 x 10^23 Mars: 6.4185 x 10^23
lora16 [44]

Answer:

1.08421 x 10^25 Kg

Step-by-step explanation:

The combined weight of these two bodies would be the addition of the masses of the two bodies.

Given that Earth weight is 5.9736 x 10^24 Kg and Venus is 4.8685 x 10^24 Kg,

The combined weight of Earth and Venus

= 5.9736 x 10^24 Kg + 4.8685 x 10^24 Kg

=10^24(5.9736 + 4.8685)

= 10.8421  × 10^24 Kg

In standard form,

= 1.08421  × 10^25 Kg

What percent of 1.60 is 6
JulsSmile [24]
N% x 1.60 = 6   (I turned it from English to math)
Can't move n% back two places to make it a decimal so I will move the number I am multiplying by n% back two places instead.
Here is a sample to show you why it works.    .34 x 57 = 34 x .57

So
.016n = 6   (.016 is 1.60 decimal moved back two places)

Now divide both sides by .016
<u>.016</u>n   = <u>6
</u><u />.016     .016      n = 375%     

Why is the percent over 100% you might ask?

What % of 1.60 is 1.60  (Answer - all of it or 100%)
So What % of 1.60 is 6  - the number 6 being much bigger than 1.60, it is not surprising that the percent is more than 100.

What % of 1.60 is 1.60  - 100%
What %  of 1.60 is 3.20 - 200%   (notice that 3.20 is twice 1.60)
What % of 1.6 is 4.80   - 300%   (notice that 4.80 is three times 1.60)
What % of 1.6 is  6.40   - 400%  (notice that  6.40 is four times 1.60)
6 (the number in the problem) is just a bit less than 6.40  so 375% makes a lot a sense.
Hope you found this helpful.

The length of a rectangular wire frame with dimensions of 12 cm × 8 cm increases at the rate of 0.5 cm per second, while its wid
arsen [322]

Answer:

2/3

Step-by-step explanation:

Since the length increases by 0.5 cm every second, after 8 seconds the length will increase by 4 cm. 12 + 8 + 12 + 8 = 40, and 40 - (16 + 16) = 8. 8/2 = 4, so the width is now 4. 16 * 4 = 64, and 12 * 8 = 96. 64/96 = 2/3.
