5(x+4)-3x+3=5 solve for x

Answers

Answer 1

Answer: X= -9

Step-by-step explanation:

Multiply the 5 by x+4 then copy the -3x+3=5. It will be 5x+20-3x+3=5.

Then subtract or add the like terms

5x-3x and 20+3. It will be 2x+23=5

Then add -23 to both sides

It will be 2x+23-23=5-23 then solve it will be 2x=-18 then divide both sides by 2 to find the value of x

2x/2=-18/2 then the final answer is x= -9. I hope it help

Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.

Answers

Answer:

Explained below.

Step-by-step explanation:

The complete question is:

Find the value of the probability of the standard normal variable Z corresponding to this area for problems 1-3.

1. P(Z < 1.62)

2. P(Z > -1.57)

3. P(-1.41 < Z < 0.63)

Solution:

Use Excel to solve the problems.

(1)

P(Z < 1.62) =NORM.S.DIST(1.62,TRUE)

= 0.9474

(2)

P(Z > -1.57) = P (Z < 1.57)

=NORM.S.DIST(1.57,TRUE)

= 0.9418

(3)

P(-1.41 < Z < 0.63) = P (Z < 0.63) - P (Z < -1.41)

=NORM.S.DIST(0.63,TRUE) - NORM.S.DIST(-1.41,TRUE)

= 0.7357 - 0.0793

= 0.6564

A line passes through the point (8,4) and has a slope of -3/4 Write an equation in slope-intercept form for this line.

Answers

Step-by-step explanation:

Hey there!

Given;

The line passed through point (8,4) and made slope (-3/4).

Note: Use one-point formula.

[tex](y - y1) = m(x - x1)[/tex]

Put all values.

[tex](y - 4) = \frac{ - 3}{4} (x - 8)[/tex]

[tex]y - 4 = - \frac{3}{4} x - \frac{3}{4} \times - 8[/tex]

[tex]y - 4 = - \frac{3}{4} x + 6[/tex]

[tex]y = - \frac{3}{4} x + 6 + 4[/tex]

Therefore, the equation is: y = -3/4x +10.

Prompt: A car is traveling down a highway at the constant speed, described by the equation “d=65t” , where “d” represents the distance, in miles, that the car travels at this speed in “t” hours.

Question 1:
1. What does 65 tell us in this situation?

a. The car travels 65 miles in 1 hour.
b. The constant of proportionality is 65 miles per hour.
c. The car traveled a total of 65 miles
d. The car is traveling 65 miles per hour.

—————————————————————

Question 2:
2. How many miles does the car travel in 1.5 hours?

The car travels □ miles in 1.5 hours.

Question 3:
3. How long does it take the car to travel 26 miles at this speed?

“Type your response in the down below”

Please Help!

Answers

Answer:

1) d

2) 97.5 miles

3)I am unsure on

Step-by-step explanation:

1) d=65t means that it is moving 65 miles per that amount of time (in this case using mph)

2) you take your equation "d=65t" and fill in your time (1.5) 65(1.5)=97.5

3) I don't know but possibly 2.5 minutes? (65/25) but I'm not sure I'm sorry

A sporting good store sells basketballs and footballs. Gavin pay $44 dollars for 3 basketballs and 2 footballs. Andrew pays $31 dollars for 1 basketball and 3 footballs. What is the price of 1 football

Answers

Answer: The price of 1 football = $ 7 and price of 1 basket ball= $10

Step-by-step explanation:

Let x = price of 1 football.

y = price of 1 basketball.

As per given,

[tex]3x+2y=44\ \ \ (i)[/tex]

[tex]x+3y=31\ \ \ \ (ii)[/tex]

Multiply 3 to (ii) , we get

[tex]3x+9y=93\ \ \ \ (iii)[/tex]

Eliminate (i) from (iii)

[tex]7y=49\\\\\Rightarrow\ y=7[/tex]

Put this in (ii), we get

[tex]x+3(7)=31\\\\\Rightarrow\ x+21=31\\\\\Rightarrow\ x=31-21=10\\\\\Rightarrow\ x=10[/tex]

Hence, the price of 1 football = $ 7 and price of 1 basket ball= $10

how to find the sale price of an item that has been discounted 25%

Answers

Answer:

Multiply the normal price of the item by .25 and then subtract that from the normal price.

Step-by-step explanation

[tex]x -(x*.25)[/tex]

x is the item

Step-by-step explanation:

100%-25%= discounted price= 75%

You do the discounted price divided by 75 to find 1%

do that times 100 to find the pre-discounted price.

e.g

find the original price of a sweater when it was on sale of 25%. the sale price is £15.00.

£15.00 = 75%

15.00 divided by 75 = 1% =£0.20

£0.20 x 100 = pre-sale price = £20.00

The price of the sweater before the sale is £20.00.
