Answers
22/35+35x3
Division comes first.
22/35=0.62857142857 or just 0.629, or 0.63
0.63+35x3
Now we multiply.
35x3=105
So now we have 0.63+105.
Lastly, we add.
0.63+105=105.63
The answer is 105.63.

For an AP the first term is 4 and last term is 31 the sum of all the term is 420 what is value of n
Answers
Answer:
n = 24
Step-by-step explanation:
From the question,
The formula for the sum of the term in an AP is given as
Sₙ = n(a+L)/2.................. Equation 1
Where Sₙ = sum of the nth term, n = number of term, a = first term, L = last term.
make n the subject of the equation
n = 2Sₙ/(a+L)................. Equation 2
Given: Sₙ = 420, a = 4, L = 31
Substitute these values into equation 2
n = (2×420)/(4+31)
n = (840)/35
n = 24.
Hence, n = 24

Addison and Alexa find ½ + ⅙. Addison says the sum is 4/6. Alexa says the sum is ⅔. Who is correct? Explain your reasoning.
Answers
Answer:
They are both correct. When the fractions are added, the sum is 4/6. 4/6 is not in its simplest form yet. It can be simplified by dividing the numerator and the denominator by 2. When divided by 2, it yields 2/3
Step-by-step explanation:
[tex]\frac{1}{2}[/tex] + [tex]\frac{1}{6}[/tex]
[tex]\frac{3 + 1}{6}[/tex] = 4/6 = 2/3

What is an equation in point-slope form of the line that passes through (-7.1) and (-3.9)?
Answers
Answer:
[tex]y-1=2(x+7)[/tex]
Step-by-step explanation:
Point-slope form: [tex]y-y_1=m(x-x_1)[/tex] where a given point is [tex](x_1,y_1)[/tex] and the slope is [tex]m[/tex]
1) Find the slope of the line (m)
Slope = [tex]\frac{y_2-y_1}{x_2-x_1}[/tex] where the given points are [tex](x_1,y_1)[/tex] and [tex](x_2,y_2)[/tex]
Plug in the points (-7,1) and (-3,9)
[tex]= \frac{9-1}{-3-(-7)}\\= \frac{8}{-3+7}\\= \frac{8}{4}\\= 2[/tex]
Therefore, the slope of the line is 2. Plug 2 into the equation as m:
[tex]y-y_1=2(x-x_1)[/tex]
2) Plug one of the given points into the equation
We plan either plug in (-7,1) or (-3,9) and it would work either way. Below you can see the equation plugging in the point (-7,1):
[tex]y-1=2(x-(-7))\\y-1=2(x+7)[/tex]
