The answer would be 5227. If you subtract what is in parenthesis first and then multiply it that should be your answer.

Answer: $5,227$

Step-by-step explanation:

Given the expression $63*83-(6-4)$ you can simplify it by applying these steps:

First, make the subtraction of the numbers that are inside of the parentheses:

$=63*83-(2)$

Apply multiplication of signs to eliminate the parentheses. Remember that:

$(-)(-)=+\\(+)(+)=+\\(-)(+)=-$

Then:

$=63*83-2$

Now, make the multplication indicated:

$=5,229-2$

Finally, subtract both numbers:

$=5,227$

Use the trigonometric ratio sin A = 0.38 to determine which angle of the triangle is < A

-Dominant- [34]

<span>According to trigonometric the formula for sin is sin = opposite/hypotenuse.Sin is defined as the ratio of sides of a right angled triangle.Hypotenuse is the is the longest side of a right-angled triangle,which is the side opposite of the right angle.So the the hypotenuse is clearly 1.3, so you divide 0.5/1.3 Hence the answer is around 0.38 The result is Angle2..</span>

Please help with number 3?

inn [45]

I would say they are equal at x = 1.47

You can tell because when x = 1.4, f(x) = 3 and g(x) = 2.7. This means that a little bit more on the x and they will touch.

However, when x = 1.5, f(x) = 3.3 and g(x) = 3.4, which means that g(x) has passed f(x) at that point, and will most likely not touch again.

This means they touch when x is between 1.4 and 1.5, but must be closer to 1.5 because they do not yet touch at 1.4.

You can say it's 1.47 or 1.48.

Can you please solve and show your work 7x + 30 = 2 + 6(x + 5)

Ksju [112]

Answer:

x=2

Step-by-step explanation:

First use the distributive property on the right side... You should get then have 7x+30 = 2 + 6x + 30

Simplify further by combining like terms to get 7x + 30 = 32 + 6x

Now subtract 6x on both sides (6x - 6x cancels out) to get 1x + 30 = 32

Next subtract 30 from both sides(30-30 cancels out) to get 1x = 2

2 divided by 1 is 2 so x = 2
