Have a good day hope this helps! :)
Answer:
Since we know that each of the three triplets are the same age we can put next to n, 3.
And given that another child is 14 years old we can put that next to the "+" sign.
In total, it would equal 32, so put the 32 after the equal sign.
It should look like this:
3n + 14 = 32
But now they want us to solve for the triplet's ages, so we just solve for n;
3n + 14 = 32
-14 -14
3n = 18
/3 /3
n = 6, the triplet's ages are 6 years old each.
Answer:
8/40 = 20%
Step-by-step explanation:
Simply count the cubes in the blue rectangle, then count the cubes in the red rectangle. Divide red by blue, multiply that by 100. Thus giving your percent.
We need to solve for the y-intercept of the line and the given values are enumerated below:
point slope = m = 4.404
mean of the x coordinate of the data point = 8.891
mean of the y coordinate of the data point = 5.519
We can use the equation of the line in a point-slope form such as:
y = mx + c
Let us solve first the value of c:
5.519 = (4.404* 8.891) +c
c = 5.519 - (39.156)
c = -33.637
the y-intercept is when x is equal to zero, we have:
y = 4.404(0) + (-33.637)
y= -33.637
The answer is -33.637 for y-intercept.
