By using the formula for arithmetic sequence, the 16th term of the progression can be obtained. Given A1=8 and d=3,
A16=A1+(n-1)d
A16=8+(16-1)(3)
A16=53
Answer:
-5
Step-by-step explanation:
Withdrawing means subtracting
Start by defining variables (things you don't know). Let's make:
t = number of true/false questions
m = number of multiple choice questions
Equation #1
total questions on the test (given to be 20) is then:
t + m = 20
Equation #2
Multiply the number of questions by the points it's worth to get the total points
3t + 11m = 100
Now, you can use substitution to combine the two equations.
t + m = 20
by subtracting m from both sides, equation 1# becomes..
t = 20 - m
substitute t for 20 - m in the second equation.
3(20 - m) + 11m = 100
Solve for m.
3(20 - m) + 11m = 100
60 - 3m + 11m = 100
8m = 100 - 60
8m = 40
m = 5
There are 5 multiple choice questions on the test.
Now use this to find t.
t + m = 20
t + 5 = 20
t = 20 - 5
t = 15
there are 15 true/false questions on the test.
D.) It is not correct because the second number tells you how far to go up or down, not across.
Second number represents y-coordinates, so they are the points in vertical direction, in that case you can't move in x-axis which is horizontal.
Hope this helps!
Answer:
positive ! the answer would be 97
Step-by-step explanation:
since you are subtracting a negative ( - - ) that automatically makes the answer positive. anytime you see subtraction sign next to a negative sign, you add !! (94 + 3 = 97! )
