Answer:
25
Step-by-step explanation:
Let n be the first integer.
Then the second integer will be (n + 1).
And the third will be (n + 2).
The sum is 78. Therefore:
[tex]n+(n+1)+(n+2)+78[/tex]
Solve for n. Combine like terms:
[tex]3n+3=78[/tex]
So:
[tex]3n=75[/tex]
Therefore:
[tex]n=25[/tex]
Therefore, the first integer is 25.
So our sequene is 25, 26, and 27.
The integer closest to zero will thus be 25.

Step-by-step explanation:
Let's solve for x.
y−4x−3y=−2x+1
Step 1: Add 2x to both sides.
−4x−2y+2x=−2x+1+2x
−2x−2y=1
Step 2: Add 2y to both sides.
−2x−2y+2y=1+2y
−2x=2y+1
Step 3: Divide both sides by -2.

A bag contains 15 blue marbles, 5 red marbles, and 11 green marbles. How many blue marbles must be removed
from the 31 marbles in the bag so that the probability of randomly drawing a blue marble is 1/3?
Answer:
7 blue marbles
Step-by-step explanation:
15 blue
5 red
11 green
Total = 31
Number of Blue marbles that must be removed to obtain a probability of :
P(blue) = 1/3
Probability = required outcome / Total possible outcomes
Let number of blue marble to be removed = x
Number of Blue becomes : 15 - x
Total becomes : 31 - x
P(blue) = 1/3
1/3 = (15 - x) / (31 - x)
1/3 * (31 - x) = 15 - x
(31 - x) / 3 = 15 - x
31 - x = 45 - 3x
-x + 3x = 45 - 31
2x = 14
x = 14 / 2
x = 7

Diego bought 4 boxes of cookies to thank his coaches at the end of the season. Each box had the same number of cookies. A friend brought 1 cookie to add to each box. Now there were 28 cookies in all. What is the unknown amount in the story?
Answer:
there are 24 cookies in the 4 boxes
there are 6 cookies in each box
Step-by-step explanation:
Let x = number of cookies in each box
If there are 4 boxes, the total number of cookies in the four boxes are 4x
If a friend brought 1 cookie to add to each box, the friend brought a total of 4 cookies
4x + 4 = 28
Solving for x
4x = 28 - 4
4x = 24
x = 6
Each box contains 6 cookies and there are 24 cookies in 4 boxes

A cell phone company recently noticed a 26% sales decrease in the month of July compared to June. Let n represent June's
sales. If y represents July's sales, which equation can be used to determine the sales in July?
0 A y = n - 0,26n
OB y = n - 0.26
0 C. y = n + 0,26n
OD. n = y-0.26
22
Answer:
Option A. is correct.
Step-by-step explanation:
Given: A cell phone company recently noticed a [tex]26\%[/tex] sales decrease in the month of July compared to June such that [tex]n[/tex] represent June's sales.
Also, [tex]y[/tex] represents July's sales.
To find: equation that can be used to determine the sales in July
Solution:
June's sales [tex]=n[/tex]
Decrease in sales [tex]=\frac{26}{100}n=0.26n[/tex]
So,
July's sales [tex]=n-0.26n[/tex]
Also,
July's sales [tex]=y[/tex]
Therefore,
[tex]y=n-0.26n[/tex]
So, option A. is correct.

The function P(1) - 5,000(1.098)' models the value, in dollars, of a painting after t years. What is the initial value of the painting?
Answer:
the answer is $5,000
Step-by-step explanation:
the question is asking what the initial value of the painting is and in the equation, they are trying to find out how much the painting will cost after t years. the 1.098 is how much the painting decreases each year and it is being multiplied by &5000 so $5000 is the original value of the painting.

porfavor: 5(x+9) = 2(x+30)= cuanto es?
Step-by-step explanation:
Primero encontramos el valor de x,
5(x+9) = 2(x+30)
=> 5x + 45 = 2x + 60
=> 5x - 2x = 60 - 45
=> 3x = 15
[tex] = > x = \frac{15}{3} [/tex]
=> x = 5
Como tenemos el valor de x entonces,
LHS = 5(x+9) RHS = 2(x+30)
= 5(5+9) = 2(5+30)
= 5 × 14 = 70. = 2 × 35 = 70
Por tanto, el valor es,
5 (x + 9) = 2 (x + 30) = 70 (Ans)
Mrs.Browns rectangular kitchen is 10 ft wide and.16 ft long, if she creates a scale drawing.With a length of 4 inches, what would be the width
Answer:
2.5 inches
Step-by-step explanation:
1 feet = 12 inches
The length is 16 ft x 12 = 192 inches
The length was scales by an unknown measure which i would represent with x . The equation is as follows
192 inches x a = 4 feet
a = 48
The kitchen was scaled by 48
10 x 12 = 120 inches

Which shows an explicit formula for a sequence whose first term is 8 and
whose common difference is 7?
Answer:
7n + 1
Step-by-step explanation:
the general formula for figuring out the formula of a sequence is a + (n - 1)d, where a = the first term and d = the common difference
The question tells u that the first term is 8 and the common difference is 7
Knowing this, you can substitute those values into the formula and simplify:
a + (n - 1)d
= 8 + (n - 1)*7
= 8 + (7n -7)
= 8 + 7n - 7
= 7n - 7 + 8
= 7n + 1
and there's your explicit formula! hope this helped!
