x+x-1+x+1 =120

3x=120

x=40

40-1=39

40+1 =41

39 +40 +41 = 120

 ages are 39 40 & 41

Consecutive integers are 1 apart
we can represent their ages as
x,x+1,x+2
so the sum is adding them all
the sum is 120

x+x+1+x+2=120
3x+3=120
minus 3 both sides
3x=117
divide both sides by 3
x=39
x+1=40
x+2=41

their ages are 39,40,41

The angle Johnny holds his pen on paper creates a linear pair. The measure of one angle is 13x+7. The measure of the second angl
lisov135 [29]

we know that

Angles in a linear pair are supplementary angles

So

Let

A-------> the first angle

B------> the second angle

A+B=180\\ ----> equation 1

A=13x+7\\ B=2A-1=B=26x+13

Substitute the values of A and B in the equation 1

13x+7+26x+13=180\\ 39x=180-20\\ x=\frac{160}{39}

\frac{160}{39}=4.10\ degrees

therefore

the answer is

the value of x is 4.10\ degrees

A shipment of ball bearings with a mean diameter of 25 mm and a standard deviation of 0.2 mm is normally distributed. By how man
Svetach [21]
You need to calculate how many times the required difference is of the standard deviation, i.e. the ratio difference / standard deviation.


These are the calculations:


Standard deviation = 0.2 mm


Difference between 25.6mm and the mean = 25.6mm - 25mm = 0.6 mm


Ratio difference / standard deviation = 0.6mm / 0.2 mm = 3.


Then, the answer is that a ball with a diameter of 25.6 mm differs 3 standard deviations from the mean.

A population of butterflies grows in such a way that each generation is simply 1.5 times the previous generation. There were 350
kap26 [50]

Answer:

378.5 or just 378

Step-by-step explanation:

This is a linear model with x representing the number of generations that's gone by, y is the number of butterflies after x number of generations has gone by, and the 350 represents the number of butterflies initially (before any time has gone by.  When x = 0, y = 350 so that's the y-intercept of our equation.)

The form for a linear equation is y = mx + b, where m is the rate of change and b is the y-intercept, the initial amount when x = 0.

Our rate of change is 1.5 and the initial amount of butterflies is 350, so filling in the equation we get a model of y = 1.5x + 350.

If we want y when x = 19, plug 19 in for x and solve for y:

y = 1.5(19) + 350

y = 378.5

Since we can't have .5 of a butterfly we will round down to 378
