X=5+y
Substitute the value of x in second equation
28x – 9y= -12
28 (5+y)-9y =-12
140 +28y -9y =-12
140 +19y= -12
19y = - 152
y= -8
Now let's find the value of x using y
x= 5+y
x= 5 + (-8)
= -3
So,
x= -3
y=-8
Answer:
5, 9
Step-by-step explanation:
To obtain the next term in a sequence add the common difference d to the previous term.
d = a₂ - a₁ = - 3 - (- 7) = - 3 + 7 = 4
Thus
a₄ = a₃ + 4 = 1 + 4 = 5
a₅ = a₄ + 4 = 5 + 4 = 9
The answer is 400x because you multiply all the numerals and then add an x to the end.
The distance covered in each month = 194.89 miles
<h3>What is unitary method ?</h3>
The unitary method entails figuring out the value of a single unit from which we can extrapolate the values of all the required units.
<h3>
What is Distance ?</h3>
Distance. A line or line segment's length between two points along the line or line segment
According to the given information
Using unitary method
Distance covered in 9 months = 1,754 miles
Distance covered in each month =
miles
So,
The distance covered in each month = 194.89 miles

Answer:
51
Step-by-step explanation:
The two tangent lines can be set equal to each other
10x - 19 = 4x + 23
Solve for x
10x - 19 = 4x + 23
-4x -4x
6x - 19 = 23
+19 +19
<u>6x</u> = <u>42</u>
6 6
x = 7
Plug in x and solve for FE
10x - 19 = 10(7)-19 = 51
