-1/6x-5=2/3x what is answer of x
a x = −6
b x = −5
c x = 3
d x = 6
Answer:
a. -6
Step-by-step explanation:
first, add 1/6x to both sides
then, make 2/3x 4/6x.
then, multiply both sides by 6.
then, divide both sides by 5.
One third of some number, x, decreased by six is thirty. What is the value of "X"
?
Answer:
X = 42
Step-by-step explanation:
1/3 / 42 = 126
36 + 6 = 42
42 - 6 = 36
so the answer is 42

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

Julie sent 200 emails last month. This month she sent 40% less. How many
emails did she send this month?
Answer:
She sent 120 emails this month.
Step-by-step explanation:
Multiply 200 by .60 (60 percent) and it will give you 120.
I used 60 instead of 40 because the problem said 40 percent less, NOT 40 percent of 200.

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
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

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.
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.

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

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!
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
