Answer:
x = 18.5
y = -12
Step-by-step explanation:
First, solve y:
y = -23 + 11
y = -12
Then, solve the main problem:
2x + 3y = 1
(Substitute y)
2x + -36 = 1
2x - 36 = 1
2x = 1 + 36 = 37
x = 37 / 2
x = 18.5

Please help! (Geometry)
Answer:
x=5
From the dashed lines on the two sides of this triangle, we can see that these two sides are congruent, or equal, to each other.
In geometry, if a triangle has two congruent sides, then we can call it a isosceles triangle.
In an isosceles triangle, the corners opposite the congruent sides are also congruent, meaning, that the angle measures of this triangle are: 88, 9x+1, and 9x+1.
We also know that angles in a triangle add up to 180 degrees.
So, we have: 88+(9x+1)+(9x+1) = 180
Simplifying: 18x + 2 = 92
Solving: 18x = 90, so x=5
Hope this helps!

-6×-15=4×+35 i need help with this problem
Answer:
x = -5
Step-by-step explanation:
-6x - 15 = 4x + 35

-6x = 4x + 50
-4x - 4x
-10x = 50
-10x/-10 = 50/-10
x = -5
The sum of two numbers is 44 and the difference is 2 What are the numbers
Answer:
21 & 23
Step-by-step explanation:
44 ÷ 2 = 22
The two numbers are going to be close to 22.
21 + 23 = 44
32 - 21 = 2
Answer:
You can try to write two equation from the question
Call x a number and y the other.
The sum of them is 44: x + y = 44
The difference (substract) is 2: x - y = 2
System:
x+y=44
x-y = 2
You can just sum both equations, as the y disappear:
2x = 46
x =46/ 2 = 23
We replace in the equation:
23 - y = 2
y = 21
And we know the numbers are 21 and 23

Factor the expression using 3 as one factor. 3x−30
Answer:
3(x - 10)
Step-by-step explanation:
3x - 30 = 3(x - 10)
Hii!
__________________________________________________________
Answer:
3(x-10)
Step-by-step explanation:
Note that both terms, 3x and -30, have a 3 in common. This is called the greatest common factor, or g.c.f.
The g.c.f. of 3x and -30 is 3. So we divide both 3x and -30 by 3, and obtain
x-10
Put parentheses around x-10
(x-10)
Next, put 3 outside the parentheses
3(x-10)

Wendell didn't make it in Nashville. Now he only
has $12 in nickels and dimes left to his name-
barely enough to pay for a bus ticket back
home. If Wendell has 3 times as many nickels
as dimes, how many dimes does he have?
Help meee lol
Answer:
Wendell only has $12 in nickels and dimes
Let Wendell have x dimes
If Wendell has 3 times as many nickels as dimes, how many dimes does he have?
Number of nickels = 3x
dime 10 c
nickel 5c
10x+5*3x = 1200 ( $12=1200 c)
25x = 1200
x= 48 number of dimes

C gives the cost, in dollars, of a cafeteria meal plan as a function of the number of meals
purchased, n. The function iſ represented by the equation C(n) = 4 + 3n.
1. Find a value of n such that C(n) = 31 is true.
Answer:
9
Step-by-step explanation:
First, write the equation.
C(n) = 4 + 3n
We know that C(n) = 31, so we can substitute it.
31 = 4 + 3n
Subtract 4 from both sides to isolate the term with the variable.
27 = 3n
Divide both sides by 3 to get the variable by itself.
9 = n
The value of n such that C(n) = 31 is true is 9
Cost functionsGiven the cost in dollars, of a cafeteria meal plan as a function of the number of meals purchased, n as:
C(n) = 4 + 3nIf the cost value C(n) is 31, hence;
31 = 4 + 3n
3n = 31 - 4
3n = 27
n = 27/3
n = 9
Hence the value of n such that C(n) = 31 is true is 9

add both equations;
13x = 39
x= 3
using 4x + 4y= 20;
