Answer:
Step-by-step explanation:
[1] 3x - 4y = -24
[2] -x - 16y = -52
Graphic Representation of the Equations :
-4y + 3x = -24 -16y - x = -52
Solve by Substitution :
// Solve equation [2] for the variable x
[2] x = -16y + 52
// Plug this in for variable x in equation [1]
[1] 3•(-16y+52) - 4y = -24
[1] - 52y = -180
// Solve equation [1] for the variable y
[1] 52y = 180
[1] y = 45/13
// By now we know this much :
x = -16y+52
y = 45/13
// Use the y value to solve for x
x = -16(45/13)+52 = -44/13
Solution :
{x,y} = {-44/13,45/13}

richard and teo have a combined age of 42 richard is 12 years older than twos age how old are richard and teo
Answer:
teo= 15 years old
richard= 27 years old
Step-by-step explanation:
richard=r
teo=t
r + t=42
t + 12= r
u can use substitution here
(t+12) + t=42
2t + 12= 42
2t=30
t= 15
to find r, you just do 15 + 12= 27
to check you can do 27 + 15= 42
The age of Richard and Teo will be 27 years and 15 years, respectively.
What is the solution to the equation?The allocation of weights to the important variables that produce the calculation's optimum is referred to as a direct consequence.
Richard and Teo are 42 years old. Richard is 12 years older than Teo.
Let x be the age of Richard and y be the age of Teo. Then the equation is given as,
x + y = 42 ...1
x = y + 12 ...2
From equations 1 and 2, then we have
y + 12 + y = 42
2y = 30
y = 15
Then the value of the variable 'x' is given as,
x = 15 + 12
x = 27
The age of Richard and Teo will be 27 years and 15 years, respectively.

What is 21=14+7x I need help
Answer:
x-1
Step-by-step explanation:
The solution to the equation 21 = 14 + 7x is x = 1.
What is the solution to the equation?Given the equation in the question:
21 = 14 + 7x
To solve the equation 21 = 14 + 7x, start by isolating the variable x to one side of the equation:
21 = 14 + 7x
Subtract 14 from both sides of the equation:
21 - 14 = 14 - 14 + 7x
Add 14 and -14:
21 - 14 = 7x
Subtract 14 from 21:
7 = 7x
Reorder the equation:
7x = 7
Divide both sides by 7:
7x/7 = 7/7
x = 7/7
x = 1
Therefore, the value of x is 1.

Answer:
A,-7
B, 4
C,13
D,2
Step-by-step explanation:
A,Step 1: Divide both sides by 4.
[tex] \frac{4x}{4} = \frac{ - 28}{4} [/tex]
[tex] x = - 7[/tex]
B,Step 1: Add 6 to both sides.
x−6+6=−2+6
x = 4
C, Step 1: Regroup terms.
4−Y=−9
Step 2: Subtract 44 from both sides.
-Y=-9-4−Y=−9−4
Step 3:Simplify -9-4−9−4 to -13−13.
[tex] \frac{ - y}{1} = \frac{ - 13}{ - 1} [/tex]
Y = 13
D,Subtract 77 from both sides.
-3x=1-7−3x=1−7

what is the effect on the graph of the linear parent function, f (x) = x, when f ( x ) is replaced by f (x +5)
Answer:
When f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
Step-by-step explanation:
We know that when we add a number 'a' to the input of the function, it would move the parent function 'a' units to the left.In other words, the rule is:
f(x + a) will shift the parent function 'a units' to the left.Given the function
[tex]f(x)=x[/tex]
Thus, when f(x) is replaced by f(x+5), it will shift the parent function '5 units' to the left.
The effect on the graph of the linear parent function is shown in the attached diagram.In the graph, the red line is representing the parent function f(x) and the blue line is representing the effect on the graph i.e. f(x+5).

The sales tax on a $750 computer at T&C Computers is $75. What is the sales tax rate? BTW
ANSWER IS 10%
Answer:
10%
Step-by-step explanation:
Price of computer = $750
Amount of sales tax = $75
Sales tax rate = Amount of sales tax / Price of computer × 100
= $75 / $750 × 100
= 0.1 × 100
= 10%
Sales tax rate = 10%
Sales tax rate = 10% of selling price

Cyndi has $55. Her sister has $115. Cyndi saves $10 per week. Her sister saves $6 per week. How many weeks will it
take for Cyndi and her sister to have the same amount of money? Write an equation and solve.
Answer: It will take 15 weeks for Cyndi and her sister to have the same amount of money.
Step-by-step explanation:
Given: Cyndi has $55. Her sister has $115.
Cyndi saves $10 per week. Her sister saves $6 per week.
Let x= Number of weeks.
Total amount of money Cyndi has = 55+10x (i)
Total amount of money sister has = 115+6x (ii)
From (i) and (ii) , we get
[tex]55+10x=115+6x\\\\\Rightarrow\ 10x-6x=115-55\\\\\Rightarrow\ 4x=60\\\\\Rightarrow\ x=\dfrac{60}{4}\\\\\Rightarrow\ x=15[/tex]
Hence, it will take 15 weeks for Cyndi and her sister to have the same amount of money.

A large bowl holds 5⅔ cups of punch. Some more punch is added to the bowl to make a total of 10 cups of punch. Let c represent the number of cups of punch that are added to the bowl. Write and solve an equation to find the number of cups of punch that are added to the bowl.
Answer:
bowl= Holds 5 ⅔ cup of punchsome more punch is added to bowl to make a total of 10 cups of punchLet c be the number of punch cups to addOkay, let's get into the formula:
5 ⅔ + c = 10
( pindah ruas )
c. = 10 - 5 ⅔
c= 13/3
c = 4 ⅓
So, the number of punch cups added to the bowl is 4 ⅓ cups
One week, Ellie earned $72.50 at her job when she worked for 5 hours. If she is paid
the same hourly wage, how many hours would she have to work the next week to earn
$232.00?
Answer:
The corect answer is 16.

because 72.50 ÷ 5 = 14.50
THEN
$232.00 ÷ $14.50 (in other words→23200 ÷ 1450) = 16

Which proportion would be used to solve the following problem. The proportion of turtles to alligators at the reptile park is 5:9. Since Beth counted 45 turtles, how many alligators are there?
Answer:
befor i go im trynna love you baby hopefully e
Step-by-step explanation:
Answer/Step-by-step explanation:
There are 81 Alligators.
The original equation was 5:9. Since the 5 turtles have been scaled up(multiplied by) 9 times. The rate for alligator will be multiplied by 9.
45 ÷ 5 = 9
9 x 9 = 81
5:9 x 9 = 45:81
