Answer:

K = - 6

Step-by-step explanation:

Let's solve your equation step-by-step.

2(4k+5)+3(3−3k)=25

Step 1: Simplify both sides of the equation.

2(4k+5)+3(3−3k)=25

(2)(4k)+(2)(5)+(3)(3)+(3)(−3k)=25(Distribute)

8k+10+9+−9k=25

(8k+−9k)+(10+9)=25(Combine Like Terms)

−k+19=25

−k+19=25

Step 2: Subtract 19 from both sides.

−k+19−19=25−19

−k=6

Step 3: Divide both sides by -1.

Answer:

The answer is -41 :)

Step-by-step explanation:

THis is the answer because if -5 is the midpoint, then y= (-5)-31 which equals -41.

Answer:

its A linear

Step-by-step explanation:

its going upwards and that means its linear and when the end point is going downwards that means its non linear  

Answer:

my answer was incorrect my mistake

Answer:

30 milkshakes and 40 root beer floats

Step-by-step explanation:

Set up a system of equation (r is root beer and m is milkshake)

2.75r+6m=290

m+10=r

Substitute

2.75(m+10)+6m=290

2.75m+27.5+6m=290

8.75m=262.5

m=30

Now plug in 30 and solve for r

30+10=40

Answer:

The answer is -6x - 30

Step-by-step explanation:

1) Expand by distributing terms.

[tex] - 6x - 6 \times 5[/tex]

2) Simplify 6 × 5 to 30.

[tex] - 6x - 30[/tex]

Thus, the answer is -6x - 30.

Answer:

-6x - 30

Step-by-step explanation:

Multiply using the distributive property.

-6x - 30

Infinitely many solutions.

Step-by-step explanation:

Any value of X makes the statement true, meaning the solution is all real numbers.

Answer:

The normal distribution is explained for the solution of this question.

Step-by-step explanation:

Normal Probability Distribution:

Problems of normal distributions can be solved using the z-score formula.

In a set with mean [tex]\mu[/tex] and standard deviation [tex]\sigma[/tex], the zscore of a measure X is given by:

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

The Z-score measures how many standard deviations the measure is from the mean. After finding the Z-score, we look at the z-score table and find the p-value associated with this z-score. This p-value is the probability that the value of the measure is smaller than X, that is, the percentile of X. Subtracting 1 by the pvalue, we get the probability that the value of the measure is greater than X.

Mean = 25, Standard Deviation = 3.8

This means that [tex]\mu = 25, \sigma = 3.8[/tex]

So

[tex]Z = \frac{X - \mu}{\sigma}[/tex]

[tex]Z = \frac{X - 25}{3.8}[/tex]

If P(X > k) = a

We have to find [tex]X = k[/tex] when Z has a pvalue of 1 - a.

If P(X < k) = a

We have to find [tex]X = k[/tex] when Z has a pvalue of a.

Answer:

32

Step-by-step explanation:

Reason: point S is between points are and t

Meaning that Line RS≅ST

So if RS=16 then ST=16

To find RT we just add ST and RS

16+16=32

Therefore RT=32

Step-by-step explanatsdfghjhgfghjk

====================================================

Explanation:

The equation is in the form y = a*(b)^x

The 'a' is the initial or starting value. In this case, a = 15.

The b is the base of the exponent which is tied to growth or decay. If 0 < b < 1, then we have decay. If b > 1, then we have growth.

Since b = 1.35, and 1.35 > 1, this means b > 1 and the given equation represents exponential growth.

Solving 1+r = 1.35 leads to r = 0.35. This means the growth rate is 35%

Answer:

24+x

Step-by-step explanation:

We need to find the expression for the following phrase i.e. the total of 24 and a number x.

Total means we need to add two numbers.

i.e.

Expression = 24+x

Hence, this is the required solution.

Answer:

The angles are supplementary to each other (their sum is 180 degrees)

x = 62°

Step-by-step explanation:

(2x+10) + 46 = 180

subtract 56 from each side

2x = 124

divide both sides by 2

x = 62°
