In an arithmetic sequence, the nth term an is given by the formula An=a1+(n−1)d, where a1is the first term and d is the common

Olin [163]

Answer: 433

Step-by-step explanation:

The given sequence : 19,42,65,88,...

We can see that the terms ha common difference as :-

$42-19=23\\65-42=23\\88-65=23$

Thus, its an Arithmetic progression with common difference (d)=23

The formula to find the nth term is :-

$a_n=a_1+(n-1)d$

Now, the 19th term of the given sequence :-

$a_{19}=19+(19-1)(23)\\\\=19+(18)(23)\\\\=19+414=433$

Hence, the 19th term of 19,42,65,88,... is 433.

Today Zack sold twice as many bags of popcorn at the ball game as he sold last Saturday. In the 2 days he sold a total of 96 bag

Alexeev081 [22]

Answer:

$s=32\\t=64$

Zack sold 32 bags of popcorn last Saturday, and 64 bags of popcorn today.

Step-by-step explanation:

Start by determining what information the question gives us, and what we need to find.

Given:

Zack sold twice as many bags of popcorn as he sold last Saturday

He sold 96 bags altogether in the 2 days

Find:

s, number of bags he sold last Saturday

t, number of bags he sold today

Equation/System of Equations:

$t=2s$ (OR "number of bags he sold today = number of bags he sold last Saturday multiplied by 2, or twice the amount he sold last Saturday)

$t+s=96$ (OR "number of bags he sold today + number of bags he sold last Saturday is equivalent to the amount of bag he sold altogether which is 96 bags as given by the question)

Solve:

We can solve this system of equations using substitution. In this case, we can substitute "2s" for "t" into the second equation giving us...

$2s+s=96\\3s=96$

Divide both sides by 3. Notice that the Division Property of Equality states that if you divide on side of the equation by something, you must divide the other side by the same quantity.

$s=\frac{96}{3}\\s=32$

Substitute 32 in for "s" to solve for "t"...

$t=2s\\t=2(32)\\t=64$

Answer:

Zack sold 32 bags of popcorn last Saturday, and 64 bags of popcorn today.

What the answer y-8=-2 (x-7)

Kamila [148]

The answer is:
Solve for y in the first equation
y=−5
y=8−x

Replace all occurrences of y with the solution found by solving the last equation for y. In this case, the value substituted is −5y=−5(−5)=8−x

Remove parentheses.y=−5−5=8−x

Solve for x in the second equation.y=−5
x=13
The answer is (13,−5) Please mark as Brainliest
