Solve for x&y using substitution but do it step by step
Answer:
x +2y = 2 ...... 1
7x + 10y = 2 ..... 2
x = 2 - 2y ..... 3
substitute 3 in 2
7(2 - 2y) + 10y = 2
14 - 14y + 10y = 2
14 - 4y = 2
- 4y = 2 - 14
- 4y = - 12
divide by - 4 on both sides
y = 3
substitute the value of y in 3
× = 2 - 2(3)
x = - 4
(x ; y )
(- 4 ; 3)

how much will the total bill be, including tip?
Answer:
$127.50
Step-by-step explanation:
All you have to do is $125 times 1.02 because it is adding to the price it is already.
$125 × 1.02.
Which is $127.50.

x=-12.5
Hope this helped! :)
Hey There!
Question:-
[tex] \sf \: - 7x+8+11x= - 42[/tex]
We need to find the value of x.
Solution:-
[tex]\sf \longmapsto - 7x + 8 + 11x = - 42[/tex]
Combine Like terms:-
[tex]\sf \longmapsto \: ( - 7x+11x)+(8)= - 42[/tex]
On Simplification :-
[tex]\sf \longmapsto \: 4x +8 = - 42[/tex]
Subtract 8 from both sides:-
[tex]\sf \longmapsto \: 4x+8 - 8= - 42 - 8[/tex]
On Simplification:-
[tex]\sf \longmapsto \: 4x + 0 = - 42 - 8[/tex]
Note that (-) and (-) equals to (+).
[tex]\sf \longmapsto \: 4x = - 50[/tex]
Divide both sides by 4:-
[tex]\sf \longmapsto \: \dfrac{4x}{4} = \dfrac{ - 50}{4} [/tex]
On Simplification:-
[tex]\sf \longmapsto \: \dfrac{ \cancel2x}{ \cancel2} = \dfrac{ \cancel{- 50}}{ \cancel4} [/tex]
[tex]\sf \longmapsto \: x = \dfrac{ - 25}{2} [/tex]
Or in Decimal :-
[tex]\sf \longmapsto \: x = -12.5[/tex]
______________________________________
Henceforth, the value of x is :-
[tex]\boxed{\huge \red{x = - \dfrac{25}{2}}} [/tex]
In Decimal:-
[tex] \boxed{\huge\red{ x = -12.5}}[/tex]

Suppose log7(10) = a and log7( 5) = b. Use the change-of-base formula along with properties of
logarithms to rewrite each expression in terms of a and b.
Step-by-step explanation:
log 10/log7=a
log10=alog7
log10=log7^a
10=7^a
log 5/log7=b
log5=blog7
log5=log7^b
5=7^b
the length of a rectangly is eight more than twice its width. if the length is less than 34, then what is the width?
Answer:
13
Step-by-step explanation:
I think u mean if the length is 34. If so heres how to work it out.
l = 2w + 8
l = 34.
34 - 8 = 26
26 / 2 = 13.
Width = 13
Answer:
x < 13
Step-by-step explanation:
→ Write an equation for the width
2x
→ Write an equation for the length
8 + 2x
→ Set up an equation
8 + 2x < 34
→ Solve
x < 13
A boat is traveling at a constant speed. In 2 hours, the boat travels 180 miles. How many hours will it
take the boat to travel 225 miles?
Answer:
2 1/2 hours
Step-by-step explanation:
For 1 hour, it would travel 90 miles.
For half of 90 which is 45 it would travel 1/2 hr.
225-180 is 45 miles, which is another half hr.
2 hrs plus 1/2 hr is 2 1/2 hours.
Find the value of n
Plz help me fast and send the answer
Answer:
n is 113
Step-by-step explanation:
Is an isosceles triangle so the base angles are equal
therefor angles sum up to 180
46 + x + x = 180
46 + 2x = 180
2x = 180 - 46
2x = 134
x = 67
now to find n
the sum of angles on a straight line equals 180
n + x = 180
n + 67 = 180
n = 180 - 67
n= 113
Answer:
the base angle of an isosceles triangle are equal
let the base angle be y°
46° + y° + y° = 180°(sum of angles in a ∆)
46° + 2y° = 180°
2y° = 180° - 46°
2y° = 134°
y° = 134/2
y°=67°
n+y=180°[sum of angles on a straight line]
n+67=180°
n=180-67
n=113°

Step-by-step explanation:
(a)
Substitute x = - 1 into f(x)
f(- 1) = 6 - 2(- 1) = 6 + 2 = 8
(b)
Substitute x = [tex]\frac{1}{3}[/tex] into g(x)
g([tex]\frac{1}{3}[/tex] ) = [tex]\frac{9}{\frac{1}{3} }[/tex] = 9 × 3 = 27
(c)
Substitute x = f(x) into h(x)
h(6 - 2x)
= 6 + (6 - 2x)² ← expand using FOIL
= 6 + 36 - 24x + 4x² ← collect like terms
= 4x² - 24x + 42
(d)
Substitute x = f(x) into g(x)
g(6 - 2x)
= [tex]\frac{9}{6-2x}[/tex]
(e)
Evaluate g(12) then substitute value obtained into f(x)
g(12) = [tex]\frac{9}{12}[/tex] = [tex]\frac{3}{4}[/tex] , then
f([tex]\frac{3}{4}[/tex] ) = 6 - (2 × [tex]\frac{3}{4}[/tex] ) = 6 - [tex]\frac{3}{2}[/tex] = [tex]\frac{9}{2}[/tex]
(f)
Evaluate f(- 9) then substitute the value obtained into h(x)
f(- 9) = 6 - 2(- 9) = 6 + 18 = 24 , then
h(24) = 6 + 24² = 6 + 576 = 582

The probability of getting blue and white counter is 0.2275
Probability is the likelihood or chance that an event will occur
Probability = n(E)/n(S)
n(E) is the number of eventsn(S) is the sample spaceIf the the probability of getting a red counter red red 0.35, the probability of getting a blue will be 0.65
Pr(getting blue and white counter) = 0.35 * 0.65
Pr(getting blue and white counter) = 0.2275
Hence the probability of getting blue and white counter is 0.2275

A chi-squared curve is symmetric about 0
Answer:
The answer is false
Step-by-step explanation:
Unlike any symmetric distribution, the chi-square distribution is non-symmetric. Accordingly, this statement cannot be trusted—b.
As chi-square does not depend on all degrees of freedom, it is a non-symmetric distribution that excludes symmetric data.
