Find the 107 terms of sequence -9,-5,-1,3,7​
Nikitich [7]

Answer:

415

Step-by-step explanation:

the nth term of the sequence is -13 + 4n

the sequence is an arithmetic progression with nth term a + (n - 1)d

a = -9, d = a5- a4 = 7 -3 =4

nth = -9 + (n -1) 4

       = -9 + 4n -4

       = -13 + 4n

hence the 107th term; -13 + 4*107

                                      -13 + 428 = 415

It takes Bruce 12 h to complete his training. It takes Oliver approximately 2 days, 2 h, and 15 min to complete
Stolb23 [73]

Answer:

Oliver completed his training work in 50.25 hours

Step-by-step explanation:

we know that

1 day= 24 hours

1 hour=60 minutes

we have

2 days, 2 h, and 15 min

<u><em>Convert days to hours</em></u>

2 days=2(24)=48 hours

<u><em>Convert minutes to hour</em></u>

15 min=15(1/60)=1/4=0.25 h

so

2 days, 2 h, and 15 min=(48)+(2)+(0.25)=50.25 h

therefore

Oliver completed his training work in 50.25 hours

OlgaM077 [116]

Answer:

Students collected

  • 85+255=340 pounds of paper;
  • 18+90=108 pounds of cans;
  • 340+108=448 pounds of paper and cans combined in September and October.

Step-by-step explanation:

In September, the students collected 85 pounds of paper and 18 pounds of cans to recycle.

In October, their goal is to collect three times the amount of paper and five times the amount of cans they collected in September.

Hence, in October they collected

  • 85\times 3=255 pounds of paper;
  • 18\times 5=90 pounds of cans.

In total, they collected

  • 85+255=340 pounds of paper;
  • 18+90=108 pounds of cans;
  • 340+108=448 pounds of paper and cans combined in September and October.

What steps do you use to solve y=x+12 and y=-x+17 an unknown number y is 12 more than an u known number x the number y is also x
Tamiku [17]

Answer:

x=2.5

Step-by-step explanation:

Solve for x in this systems of equations, we already have two values which equal y so half the work is finished for us.

Starting with the equation:

x+12=17-x

Add x to both sides to remove the negative x on the right side of the equation:

2x+12=17

Subtract 12 from both sides to remove the 12 on the left side of the equation:

2x=5

Divide both sides by 2 to cancel out the x coefficient

x=2.5
