77th term for -10,-8,-6
Answers
9514 1404 393
Answer:
142
Step-by-step explanation:
The first term of this arithmetic sequence is -10. The common difference is -8-(-10) = 2. The n-th term is ...
an = a1 +d(n -1)
an = -10 +2(n -1) = 2n -12
Then the 77th term is ...
a77 = 2(77) -12 = 154 -12
a77 = 142
The 77th term is 142.

Answer:
Bagels are 4 and Muffins are 2
Step-by-step explanation:
solve the system of equations
Answer:
Bagels are 4 and the muffins are 2 or the first answer
Step-by-step explanation:
2b+m=10
3b+m=14
we can subtract the equations
-b=-4
multiply both sides by -1 to get
b=4 meaning a bagel is four dollars
we can then subsitute this
2(4)+m=10
8+m=10
subtract 8 from both sides
m=2
subsitute these into the second equation to check
3(4)+(2)=14
12+2=14
14=14
Therefore the answer is Bagels are 4 and the muffins are 2 or the first answer

Find the inequality represented by the graph
Answers
Answer:
y ≥ 1/2xStep-by-step explanation:
Given the following inequality, we know that y must be greater than or equal to x because the line is not dashed, and is shaded above the line.
Now to find the equation just pretend that this is just a normal linear equation, and solve for the equation.
So since the y intercept is 0, and there is a rise of 1 for a run of 2 or 1 unit up every two units to the right, the corresponding linear equation is y = 1/2x.
Now since this is an inequality where y is greater than or equal to x.
y = 1/2x → y ≥ 1/2x

Answers
Answer:
215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left
Step-by-step explanation:
we have 5,814 meters of rope and we are told to calculate the number of 27 meters sections that we can cut:
you have to divide 5,814 meters by 27 meters = 215.333
that means that you have 215 sections of rope that measure 27 meters in length, and you also have 9 meters of rope left (0.333 x 27 = 9)
