Answer: He bought 7 nachos.
Step-by-step explanation:
Let x= Number of cokes
y = Number of nachos
As per given , we have
x+y=12 (i)
2.50x+3.50y=37 (ii)
Multiply 2.5 on both sides of (i), we get
2.5x+2.5y= 30 (iii)
Subtract (iii) from (ii), we get
y=7 (iv)
Put value of y from (iv) in (i), we get
x+7=12
⇒ x= 12-7
⇒ x=5
Hence, he bought 5 cokes and 7 nachos.
A number increased by three is the same as quadrupling that number increased by five all divided by four. What is le number?
Answer:
The number is infinity
Step-by-step explanation:
Let the unknown number be x
if the number increased by three, then we have;
x + 3
Also quadrupling that number increased by five all divided by four is expressed as;
(4x+5)/4
Equating bith expressions and calculating x;
x+3 = (4x+5)/4
cross multiply;
4(x+3) = 4x + 5
4x+12 = 4x + 5
4x-4x = 5 - 12
0x = -7
x = -7/0
x = ∞
Hence the number is infinity

Answer:
The slope is negative. The relationship is proportional
Step-by-step explanation:
The value of y is directly proportional to the value of x. If y = 24 when x = 6, what is the value of y when x = 48?
Answer:
192
Step-by-step explanation:
We know that x is 1/4 of y, since 6 is 1/4 of 24. Therefore, we can multiply 48 by 4 to get 192!

Enter the ordered pair for the vertices for T(3, –2)(QRST).
Given:
The figure QRST.
The rule of translation is [tex]T_{(3,-2)}(QRST)[/tex].
To find:
The coordinate of vertices after translation.
Solution:
According to the given rule of translation is [tex]T_{(3,-2)}(QRST)[/tex], we get
[tex](x,y)\to (x+3,y-2)[/tex]
From the given figure it is clear that the vertices of QRST are Q(1,3), R(3,-3), S(0,-2) and T(-2,1).
Using the above rule, we get
[tex]Q(1,3)\to Q'(1+3,3-2)=Q'(4,1)[/tex]
[tex]R(3,-3)\to R'(3+3,-3-2)=R'(6,-5)[/tex]
[tex]S(0,-2)\to S'(0+3,-2-2)=S'(3,-4)[/tex]
[tex]T(-2,1)\to T'(-2+3,1-2)=T'(1,-1)[/tex]
Therefore, the coordinates of the vertices after translation are Q'(4,1), R'(6,-5), S'(3,-4) and T'(1,-1).
The ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]
The coordinates of QRST are:
[tex]\mathbf{Q = (1,3)}[/tex]
[tex]\mathbf{R = (3,-3)}[/tex]
[tex]\mathbf{S = (0,-2)}[/tex]
[tex]\mathbf{T = (-2,1)}[/tex]
The transformation rule of [tex]\mathbf{T(3,-2)}[/tex] is:
[tex]\mathbf{(x,y) \to (x + 3,y -2)}[/tex]
So, we have:
[tex]\mathbf{Q' = (1 + 3,3 -2)}[/tex]
[tex]\mathbf{Q' = (4,1)}[/tex]
[tex]\mathbf{R' = (3 + 3,-3 -2)}[/tex]
[tex]\mathbf{R' = (6,-5)}[/tex]
[tex]\mathbf{S' = (0 + 3,-2 -2)}[/tex]
[tex]\mathbf{S' = (3,-4)}[/tex]
[tex]\mathbf{T' = (-2 + 3,1 -2)}[/tex]
[tex]\mathbf{T' = (1, -1)}[/tex]
Hence, the ordered pairs for the vertices of T(3, –2)(QRST) are
[tex]\mathbf{Q' = (4,1)}[/tex] [tex]\mathbf{R' = (6,-5)}[/tex] [tex]\mathbf{S' = (3,-4)}[/tex] and [tex]\mathbf{T' = (1, -1)}[/tex]

I need help on this problem may you help
Answer:
Step 1: Simplify both sides of the equation.
5x+1=6x−x
5x+1=6x+−x
5x+1=(6x+−x)(Combine Like Terms)
5x+1=5x
5x+1=5x
Step 2: Subtract 5x from both sides.
5x+1−5x=5x−5x
1=0
Step 3: Subtract 1 from both sides.
1−1=0−1
0=−1
Answer:
There are no solutions.
Step-by-step explanation:
Answer:
no solution
Step-by-step explanation:
Given
5x + 1 = 6x - x , that is
5x + 1 = 5x ( subtract 1 from both sides )
5x = 5x - 1 ( subtract 5x from both sides )
0 = - 1 ← not possible
