Answer:
x = 10
Step-by-step explanation:
We see and show that x = 10
This makes y = 5 and z = 7 as 5-7 (y-z) = -2
As y5-z7 = -2 then we add 10 = 8
x+y-z = 10x-2yz = 8
x-y+z = 10 -5 +7 = 12 we know x = 10
We cna now prove.
x+y-z =8
x+5y-7z = 8
x +-2yz = 8
x = 8+2yz
x= 10
And prove
(x-5y)+7z= 12
x-y =12-7z
x = 5+5y
x=10
as x-5 (=5+7z) = 12
Have got the right answer here. Hope it helps.

calculate the surface area of a solid box in the shape of a cube with side length 1cm
Answer:
6 cm ^2
Step-by-step explanation:
Answer:
The surface area is 6 cm².
Step-by-step explanation:
Given that a cube has side lengths all the same. Then you have to use surface area formula, S.A = 2(length×width) + 2(length×height) + 2(width×height) :
Let length = 1cm,
Let width = 1cm,
Let height = 1cm,
[tex]s.a = 2(1 \times 1) + 2(1 \times 1) + 2(1 \times 1)[/tex]
[tex]s.a = 2 + 2 + 2[/tex]
[tex]s.a = 6 \: {cm}^{2} [/tex]

4. Francisco says, "36 is 75% of 48." Is Francisco correct or incorrect?
Show your reasoning using a Tape Diagram."
Answer:
see below
Step-by-step explanation:
Is means equal and of means multiply
36 = 75% * 48
36 = .75* 48
36 = 3/4* 48
36 =36
Using the tape diagram
Divide 48 into 4 pieces
12 12 12 12
Then circle 3 of them
12 +12 + 12
36
Answer:
Correct
Step-by-step explanation:
75% of 48
75/100 × 48
3/4 × 48
36
Divide the tape of length 48 units into 4 parts, 3 parts add up to 36

Explain how to graph the point (6,4) on a coordinate plane.
Answer:
here is how
Step-by-step explanation:
the x (6) is the horixontal ways on the co-ordinate plane. you go right until you reach the six. the y (4) is vertical. take the point that is on 6,0. and move it up until you see it on 4. now you have the coordinates 6,4.
Please help. The correct and best answer gets brainiest! 29 points!!
(please make sure you are correct and show your work, no guessing)
Answer:(15, 100)
Step-by-step explanation:
first find the coordinates of the point above (3, 20)
you just look at the x axis and where the point is in this case x would be 6 and then you find y which would be 40
so the coordinate would be (6, 40)
now subtract (6, 40) by (3, 20)
6-3= 3
40- 20= 20
you get the first coordnites which is what you add (12,80) to
12 +3= 15
80+ 20= 100
you get the coordinates (15, 100)

The shelf life of a packed food follows a normal distribution, with a mean of 60.5 days and a standard deviation of 7.2 days. Rounded to the nearest hundredth, what is the probability that a package lasts fewer than 50 days?
Answer:
[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]
And we can find the probability using the normal standard distribution or excel and we got:
[tex]P(z<-1.46)=0.0721[/tex]
Step-by-step explanation:
Let X the random variable that represent the shelf life of packed food of a population, and for this case we know the distribution for X is given by:
[tex]X \sim N(60.5,7.2)[/tex]
Where [tex]\mu=60.5[/tex] and [tex]\sigma=7.2[/tex]
We are interested on this probability
[tex]P(X<50)[/tex]
For this case we can solve this problem with the z score formula:
[tex]z=\frac{x-\mu}{\sigma}[/tex]
If we apply this formula to our probability we got this:
[tex]P(X<50)=P(\frac{X-\mu}{\sigma}<\frac{50-\mu}{\sigma})=P(Z<\frac{50-60.5}{7.2})=P(z<-1.46)[/tex]
And we can find the probability using the normal standard distribution or excel and we got:
[tex]P(z<-1.46)=0.0721[/tex]

PLS NEED HELP ASAP WITH TRIG NEED TO SHOW FULL WORK
Answer:
10ft
Step-by-step explanation:
Answer:
14.4 m
Step-by-step explanation:
let the height of the tower from line of sight be x, then
tan23° = [tex]\frac{opposite}{adjacent}[/tex] = [tex]\frac{x}{30}[/tex] ( multiply both sides by 30 )
30 × tan23° = x , thus
x ≈ 12.7 m
Total height of tower = 12.7 + 1.7 = 14.4 m ( to the nearest tenth )
is the relation a function?
please help.
Answer:
Yes
Step-by-step explanation:
A function has one input (x-value) per output (y-value).
In other words, a relation that does not repeat any x values is a function.
{(3,4) , (5,0) , (2,4) , (-5,-5)}
The domain of the relation is:
{-5,2,3,5}
Since none of the numbers repeat in the domain, the relation is a function.

Find the 23rd term of this sequence -25,-15,-5,5....
Answer:
195
Step-by-step explanation:
To find the 23rd term of this sequence, we can use the arithmetic sequence formula [tex]a_{n} =a_{1} +(n-1)d[/tex] where,
[tex]a_{n}[/tex] = [tex]n^{th}[/tex] term
[tex]a_{1}[/tex] = first term
[tex]n[/tex] = term position
[tex]d[/tex] = common difference
[tex]a_{23}=-25+(23-1)10[/tex]
[tex]a_{23} =195[/tex]
