question 4. The right answers are 1,3 and 4
Question 5. No they are not balanced.
Step-by-step explanation:
1.
7/9 * 8 = 6 2/9
56/9 = 6 2/9
2.
8 + 11.5 = 20.5
19.5 ≠ 20.5
3.
23.42 - 8 = 15.42
15.42 = 15.42
4.
11 * 8 = 88
88 = 88
5.
40/8 = 6
40/8 ≠ 6

given that f(x)=2x/3 evaluate f^-1(6)
Answer:
9
Step-by-step explanation:
we know by definition that
[tex]f^{-1}(f(x))=x\\\\f^{-1}(\frac{2x}{3})=x\\\\f^{-1}(x)=ax\\\\f^{-1}(\frac{2x}{3})=a(\frac{2x}{3})=x\\\\f^{-1}(x)=\frac{3x}{2}[/tex]
so now we evaluate
[tex]f^{-1}(6)=\frac{3*6}{2}\\\\=3*3\\\\f^{-1}(6)=9[/tex]
and if we want to do an extra step
[tex]f^{-1}(f(6))=6\\\\f^{-1}(\frac{2*6}{3})=f^{-1}(4)=\frac{3*4}{2}=6[/tex]
which works.
Decrease 65kg by 3/5
Step-by-step explanation:
answer........ . . .......
Answer:
26kg
Step-by-step explanation:
Firstly, we need to find 1/5 of 65kg so we do: 65/3=13
Then, to find 3/5 of 65kg we multiply 13*3 to get 39
Lastly, we subtract 39 from 65 to get 26kg
Someone please explain, it's most of my homework! I already did half the problem! Ellie bought 5 cups of apple juice and 7 sandwiches for $25.00. Jim bought 2 cups of apple juice and 3 sandwiches for $10.50. How much did each cup of apple juice cost? How much did each sandwich cost. I set up the equations 5a+7s=25 and 2a+3s=10.5. How do I solve them?
Answer:
5 cups of apple juice and 7 sandwiches for a total of 25 bucks Jim bought 2 cups of apple juice and 3 sandwiches for $10.50Now we must form some sort of equation for the following: (1) 5a+7s=25(2) 2a +3s =10.5Let us isolate for one variable 3s= 10.5-2a s= 3.5 -2/3a Plug that into (1)5a + 7 (3.5 -2/3a) = 25 a=1.5 Hence each apple juice cost 1.5 Now we can plug that into (2) to solve for the sandwich costs= 3.5- 2/3(1.5) s=2.5 Rate positively and give brainlist¿Una ecuación algebraica de5 grado puede Tener todas sus raices complejas y no reales?

Which rectangular equation is formed by eliminating the parameter?
y = t^3
x = t + 5
Given :
Two equations :
y = t³
x = t + 5
To Find :
Rectangular equation formed by eliminating the parameter.
Solution :
Putting value of t from second equation to first equation.
We get :
[tex]y = ( x-5)^3[/tex]
Also, t from equation first :
[tex]t = \sqrt[3]{y}[/tex]
Putting the value of t and equation two, we get :
[tex]x = \sqrt[3]{y}+5[/tex]
Therefore, rectangular equation is formed by eliminating the parameter is :
y = ( x - 5)³ and x = ∛y + 5 .
The rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.
What are parametric equations?A parametric equation in mathematics specifies a set of numbers as functions of one or more independent variables known as parameters.
The options are:
y = (x + 5)³x = (y + 5)³y = (x - 5)³y = (x - 5)²It is given that:The parametric equations are:
y = t³
x = t + 5
From the second equation that is x = t + 5
Take the value of t and plug in the equation y = t³:
t = x - 5
y = (x - 5)³
The above equation represents a cubic equation.
Thus, the rectangular equation is y = (x - 5)³ which is obtained from the parametric equations y = t³ and x = t + 5 option (3) y = (x - 5)³ is correct.

How to divide 7 divided by 7/4
Answer:

Step-by-step explanation:
7÷7/4
in these cases we multiply by the reciprocal
7× 4/7
7 and 7 can be cancelled with each other
the remaing answer = 4
Answer:
1/4
Step-by-step explanation:
First, since the numerator is 7 you want to see how many times you can divide that.
So, you can only divide 7 by 7 1 time so that turns into 1.
Hence, your numerator is now 1 and denominator stays the same so its..

In a paint factory, an old conveyer line has filled 40 barrels of paint, and is filling more at a rate of 1 barrel per minute. A worker just switched on a newer line that can fill 3 barrels per minute. In a little while, the two lines will have filled an equal number of barrels. How many barrels will each line have filled?
Write a system of equations, graph them, and type the solution.
Answer:
5 minutes
Step-by-step explanation:
let the time after which two lines will have filled an equal number of barrels is 'X' minutes.
so, according to the question after 'X' minutes;
⇒ number of barrels in old conveyer line = number of barrels in new conveyer line
⇒ 40x + 2X = 10X
⇒ X = 5
Add the expressions: 9(20m - 5) + (m +7)
Answer:
181m - 38
Step-by-step explanation:
Hey there!
9(20m – 5) + (m + 7)
DISTRIBUTE
9(20m) + 9(–5) + m + 7
9(20m) + 9(–5)
9(20m) = 180m
9(–5) = -45
NEW EQUATION: 180 – 45 + m + 7
COMBINE your LIKE TERMS
(180m + m) + (–45 + 7)
“m” itself is understood as an invisible 1!
180m + m = 181m
–45 + 7 = –38

Bertha deposited $1000 into a retirement account when she was 18. How much will Bertha have in this account after 50 years at a yearly simple interest rate of 7.5%?
Answer:
$4750
Step-by-step explanation:
Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
Amount = SI + P
The amount Bertha will have in his account after 50 years is $4750.
What is simple interest?Simple interest is the interest calculated on the principal at a given rate for a time period.
The simple interest formula is given as,
SI = P x R x T / 100
P = principal
R = rate
T = time
We have,
P = $1000
T = 50
R = 7.5%
A = SI + P
SI = (1000 x 7.5 x 50) / 100
SI = 1000 X 7.5 X 50 / 1000
SI = $3750
A = SI + P
A = 3750 + 1000
A = $4750
Thus,
The amount Bertha will have in his account after 50 years is $4750.

PLEASEEEEE HELPPPP!
Answer:
option 4
Step-by-step explanation:
put like terms on either side
9x + 2a = 3a - 4x
subtract both sides by 2a
9x = a - 4x
add both sides by 4x
13x = a
divide both sides by 13
x = a/13
please give thanks, hit that heart button :)
Answer:
4.) a/13
Step-by-step explanation:
9x + 2a = 3a - 4x
9x + 4x = 3a - 2a
13x = a
13x/13 = a/13
x = a/13
What is the solution to 2/3(9x-6)=4(x+2)+ 2 round to the nearest hundredth
Answer:
7
Step-by-step explanation:
First expand 2/3 (9x-6) = 4 (x+2)+ 2 By doing 2/3 (9x - 6)/3
Which gives you 2/3 (9x - 6)
Then you factor it 2/3 (9x - 6) 6 (3x - 2) get 6 (3x - 2) / 3
then you divide 6/3 with 2
Getting 2 (3x - 2)
The use the distributive law
2 x 3x - 2 x 2
simplify the equation
6x - 4
expand 4 (x +2) + 2: 4x + 10
which then equals 6x-4=4x+10
add 4 to both sides
6x-4+4=4x+10+4
simplify
6x=4x+14
subtract 4x from both sides
simplify again
2x=14
divide both sides by 2
2x/2 = 14/2
simplify one last time and get the answer
