Answer:

X=4

Step-by-step explanation:

Answer and Step-by-step explanation:

To get x, we need to put everything on the right. We start off by multiplying each side by 3.

3 × [tex](\frac{7+2x}{3} ) =[/tex] 5 × 3

7 + 2x = 15

Now, we subtract 7 from each side.

(7 + 2x) - 7 = 15 - 7

2x = 8

Finally, we divide each side by 2.

2x ÷ 2 = 8 ÷ 2

x = 4

The answer to this equation is x = 4.

I hope this helps!

Answer: RI 18,823.14

Step-by-step explanation:

I guess that we want to find the 12.6% of Rl 149,390

First, we assume that Rl 149,390 is the 100%

Then we can write an equation like:

Rl 149,390 = 100%

Then if the amount X is the 12.6%, we also have the equation:

X = 12.6%

Then we have the two equations:

X = 12.6%

Rl 149,390 = 100%

If we take the quotient between these two equations we get:

(X/Rl 149,390) = (12.6%/100%)

Solving this for X we get:

X =  (12.6%/100%)*(Rl 149,390) = RI 18,823.14

Question:

The identity [tex]A^2 - B^2 = (A + B) (A - B)[/tex] is true for all values of A and B. Compute the whole number value of [tex]2021^2 -2022^2[/tex]

Answer:

[tex]2021^2 - 2022^2 = -4043[/tex]

Step-by-step explanation:

Given

[tex]A^2 - B^2 = (A + B) (A - B)[/tex]

Required

Solve:  [tex]2021^2 -2022^2[/tex]

In: [tex]2021^2 -2022^2[/tex]

[tex]A = 2021; B = 2022[/tex]

[tex]A^2 - B^2 = (A + B) (A - B)[/tex] becomes

[tex]2021^2 - 2022^2 = (2021 + 2022)(2021 - 2022)[/tex]

[tex]2021^2 - 2022^2 = (4043)(-1)[/tex]

[tex]2021^2 - 2022^2 = -4043[/tex]

Answer:

7. divide both sides by 18.

8. subtract 4 from both sides.

9. add 3 on both sides.

10. multiply by 6 on both sides

Answer:

Step-by-step explanation:

Answer:

39

Step-by-step explanation:

Let, total rooms girls booked be x and total rooms girls booked be y.

entire hotel was booked except two rooms.

so, total = 158-2 = 156

x+ y = 156

this is equation 1.

also, girls are using three times more room than boys.

so, y=3x

substituting y=3x in 1st equation,

x+ 3x = 156

or, 4x = 156

or, x= 156/4

x= 39

Answer:

Im not really sure what the question is asking but the drama club could sell 70 adult tickes and 30 student tickes and they would make $950.

Step-by-step explanation:

Answer:

possible solution (10,80)

Step-by-step explanation:

Variable Definitions:

x=the number of student tickets sold

y= the number of adult tickets sold

“at most 100 people"→100 or fewer tickets

Therefore the total number of tickets sold, x+y, must be less than or equal to 100:

x+y≤100

“no less than $770"→$770 or more

Each student ticket sells for $6, so x student tickets will bring in 6x dollars. Each adult ticket sells for $11, so y adult tickets will bring in 11y dollars. Therefore, the total amount of revenue 6x+11y must be greater than or equal to $770:

6x+11y≥770

Solve each inequality for y:

x+y≤100

y≤−x+100

6x+11y≥770

11y≥770−6x

y≥ -6/11x+70

Graph y≤100−x by shading down and graph y≥-6/11x+70

by shading up

Step-by-step explanation:

Answer:

Yes, there is significant evidence to support the claim that sample standard deviation is higher than that claimed by the manufacturer

Step-by-step explanation:

Sample standard deviation, s = 3.2

Population standard deviation, σ = 2

Defining the Null and alternative hypothesis :

H0 : σ = 2

H1 : σ > 2

The test statistic :

Use the Relation :.

[(n - 1)*s²] ÷ σ²

[(10 - 1) * 3.2²] ÷ 2²

(9 * 10.24) ÷ 4

92.16 ÷ 4

= 23.04

We obtain the Pvalue for the distribution :

Using the Pvalue from Chisquare distribution calculator :

Pvalue(Chisquare score, df)

df = n - 1 = 10 - 1 = 9

Pvalue(23.04, 9) = 0.006107

Decision :

If Pvalue is < α ; Reject H0 ; α = 0.05

0.006107 < 0.05 ; We reject H0

Answer:

See solution below

Step-by-step explanation:

The ball will hit the ground at whrn t = 0

Given the height of the ball modeled by the expression

h(t) = -16t^2 + 64

0 =  -16t^2 + 64

16t^2 = 64

t^2 = 64/16

t^2 = 4

t = 2sec

The ball will hit the ground 2secs after

The domain are the values of the input values t and this values start from 2 and greater. Hence the domain of the function is {2, ∞}

when t = 2

h (2) = -16(2)^2 + 64

h(2) = -64+64

h(2) = 0

Hence the range are the output values i.e the height.

The range are within the range {0, ∞}

Step-by-step explanation:

Area of triangle + area of square + area of triangle = total area

(Area of a triangle: A = 1/2bh)

(Area of a square: A = bh)

Area of smallest triangle =

A = 1/2 (2) (2) = 2

Area of largest triangle=

A = 1/2 (2) (6) = 6

Area of the square =

A = 2 x 2 = 4

Total shape:

2 + 4 + 6 = 12

Answer:

6.67 yards

Step-by-step explanation:

20 feet. The builder asks him to give the measurements in yards. What will be the length in yards?

Please note that:

1 foot = 0.333 yard

20 feet = x yards

Cross Multiply

1 foot × x yards = 20 feet × 0.333 yards

x yards = 20 feet × 0.333 yards/1 foot

x yards = 6.66667 yards

Approximately = 6.67 yards

Therefore, the measurements in yards is 6.67 yards.

Answer:

2469 x 2/3= 1646

personally, I solve it by dividing the 2469 by 3 to get 1/3.

2469/3= 823

then, double it to get 2/3.

823x2= 1646
