Answer:5

Step-by-step explanation:

Answer:

x=−y+

−1/2

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.

−2x

−2

=

2y+1

x=−y+

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.

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

Answer: Mr Smith bought 7 pepperoni pizza

Step-by-step explanation:

Step 1

cost of cheese pizza  =$11

pepperoni pizza cost =$12.50

let number cheese pizza be represented as c

and number of pepperoni pizza be represented as p

such that the total number of pizza  bought which equals 13 can be represented as

c+ p= 13

and total cost of both pizza  can be expressed as

11c+ 12.50p =153.50

Step 2 Solving

 c+ p= 13

11c+ 12.50p =153.50

By elimination method, Multiply equation 1 by 11 and subtract the new equation from equation 2

11c+ 12.50p =153.50

11c+ 11p=143.

1.5p =10.5

p= 10.5/ 1.5 =7

c+ p= 13

c= 13-p =13-7=6

Therefore Mr Smith bought 6 cheese pizza and 7 pepperoni pizza

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

I'm new so don't just take my answer

Step-by-step explanation:

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!

Answer: How to answer radical questions and such:

The most basic is to isolate one of the square roots, square both sides, and this will usually yield less square roots than when you started with. Keep repeating until you have no more square roots. This works pretty well in most cases, there are sometimes some tricks, arising from the particular problems themselves ways, which allow you to solve the equations much faster

The solving methods for Square root and radical equations are given below.

An equation wherein a variable is withinside the radicand of a thorough expression is referred to as a thorough equation. As usual, whilst fixing those equations, what we do to at least one aspect of an equation we ought to do to the alternative aspect as well. Once we isolate the radical, our approach could be to elevate each facet of the equation to the strength of the index. This will remove the radical.

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)
