Answer:
1) 25
2) 20
Step-by-step explanation:
1)
Since these are vertical angles, they are congruent. Therefore, 3x=75, and x=25 degrees.
2)
Once again, these are vertical angles.
2+3x=62
3x=60
x=20 degrees
Hope this helps!
Answer:
-18
Step-by-step explanation:
add 25 on both sides
f/9 = -2
multiply by 9 on both sides
f = -18
Carlos did not use order of operations. The order of operations goes first you do <span>Parentheses, Exponents, Multiplication, Division, Addition, Subtraction. First you do the parentheses which is 2 x 6 so now your equation is 20 - 12 + 8 / 4. Since you don't have any exponents nor multiplication left you move onto divison which is 8 / 4. Know your equation is 20 - 12 + 2. You do addtion which is 12 + 2. Then you do subtraction 20 - 14 which equals 6.
Hope this helps :)</span>
Answer:
hello :
note :
the nth term of an arithmetic sequence is :
An =A1+(n-1)d ....a common difference is : d ... A1 : the first term
in this exercice : A1 = - 1 d = (-6) -(- 1) = -5
An = - 1 + (n - 1)(-5)
the expression is : An = - 5n +4
