What are coefficients in the expression 2+6+10b-8a

Mathematics
1 answer:
tiny-mole [99]2 years ago
5 0

\boldsymbol{Answer:} 10 and -8 ✅

\boldsymbol{Step-by-step\;explanation:}

Hii, do you need to know the co-efficients in the expression "\boldsymbol{2+6+10b-8a}"? No problem! (:

<h3><u>What are Co-efficients?</u></h3>

A "co-efficient" is a number that comes before a variable.

Here there are only two such numbers: "10" and "-8"; 10 comes before b, and -8 comes before a. 2 and 6 don't come before any variables at all, so they are not co-efficients.

Voila! There's our solution, cheers! (:

Hope that this helped! Best wishes.

Angle A and Angle B are supplementary. Angle A has a measure of 3x - 6 and Angle B has a measure of 54. What is the value of x?
Anni [7]

Answer:

44 degrees

Step-by-step explanation:

Since they are supplementary, they add up to 180. This means that

3x - 6 + 54 = 180

Solving,

3x + 48 = 180

subtract 48 from both sides

3x = 132

divide both sides by 3

x = 44 degrees

Can anyone please help me with this? i need a step by step explanation please! very appreciated:)
EastWind [94]

Answer:

Step-by-step explanation:

x and y are variables. That means they represent numbers that are unknown. When we solve for x or y, we are trying to find what number the variable represents.

Y is a number that equals both 5x-9 and 3x+7. If it is a number, it can only have one value, so we can say that 5x-9 and 3x+7 have the same value.

In other words, 5x-9 = 3x+7.

Another way of thinking about this step is substitution. y=3x+7, so in the equation y=5x-9, we can replace the y with 3x+7. It will give 3x+7 = 5x-9.

In either case, we have this new equation

5x-9 = 3x+7.

From here it's just simple algebra- subtract 3x from each side

2x -9 = 7

and add 9 to each side

2x = 16

and divide each side by 2.

x = 8.

All these steps work because if two things equal each other, when you do the same thing to both of them (such as add 9), the new values will still equal each other.

Now that we know that x = 8, we can take one of the original equations

y=5x-9

and put 8 in for x.

y=5*(8) -9.

If x represents the value 8, we can obviously switch out x for 8.

Now simplify

y=40 -9

y = 31

Now we know that x = 8 and y = 31.

DENIUS [597]

Answer:

The value of the test statistic is t = -2.09

Step-by-step explanation:

The null hypothesis is:

H_{0} = 6.6

The alternate hypotesis is:

H_{1} \neq 6.6

Our test statistic is:

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

In which X is the sample mean, \mu is the value tested at the null hypothesis, \sigma is the standard deviation(square roof of the variance) and n is the size of the sample.

In this problem, we have that:

X = 6.5, \mu = 6.6, \sigma = \sqrt{0.64} = 0.8, n = 280

So

t = \frac{X - \mu}{\frac{\sigma}{\sqrt{n}}}

t = \frac{6.5 - 6.6}{\frac{0.8}{\sqrt{280}}}

t = -2.09

The value of the test statistic is t = -2.09
