4 times the sum of a number and 5 is 1 less than the same number
x = a number
4(x + 5) = x - 1
Now, let's distribute the 4
4x + 20 = x - 1
Subtract x and 20 from both sides.
3x = -21
Divide both sides by 3
x = -7

Given: B is the midpoint of segment AC. AB = 3x - 1, BC = x +7
Find: The length of segment AC
22
02
011
Answer:
hope it helps
plz mark as brainliest
Length of [tex]\boldsymbol{AC}[/tex] is [tex]\boldsymbol{22}[/tex] units.
"To understand the calculation, check below."
Midpoint
The middle point of the a line segment is called the midpoint.
It's really the centroid of both segment and the ends, and it is equidistant from both.
It cuts the portion in half.
[tex]B[/tex] is the midpoint of [tex]
AC[/tex] [tex]\boldsymbol{AB=BC}[/tex][tex]3x-1=x+7[/tex] [tex]2x
AC=8[/tex] [tex]\boldsymbol{x=4}[/tex]
So,[tex]BC=4+7[/tex] [tex]=\boldsymbol{11}[/tex]
Therefore,[tex]AC=2BC[/tex] [tex]=2 \times 11\\=\boldsymbol{22}[/tex]Length of [tex]\boldsymbol{AC}[/tex] is [tex]\boldsymbol{22}[/tex] units.

Morris borrowed $6 from his mother. so far, he has repaid $4. if debt is represented as a negative number, what number sentence shows the amount of jack's remaining dept.?
if it was negitive I would be -2
Step-by-step explanation:
so 6-4=2 and if you make that negative it would be -2
Answer:
-$6 + $4 = -$2
Step-by-step explanation:
Since Morris borrowed 6 dollars to begin with, the first term in my equation is -6$, representing the debt he has incurred from taking a loan of 6 dollars from his mother. After paying $4 dollars, he would still be in debt of $2 to his mother. Since he is still in debt of 2 dollars, the furthest right term in my aforementioned equation is -$2.

R = √(-3² + 7²)
R = √(9 + 49)
R = √(58)
R = 7.62
tangent (Θ) = 7 / -3
Θ = arctan (7 / -3)
Θ = 113.2° counterclockwise from the x-axis

The required area of tortilla is 16π square inches.
What is an area of a circle?
Area of a circle is defined as the region occupied by the circle in two-dimensional plane.
Mathematically,
A = π (d/2)²
where d is the diameter of circle
or, A = π r²
where r is the radius of circle.
Now, given diameter of tortilla is 8inches.
⇒ d = 8inches
Since,tortilla is a circle
So, area of tortilla A = π (d/2)²
⇒ A = π (8/2)²
⇒ A = π (4)²
⇒ A = 16π square inches
Hence, required tortilla's area is 16π square inches.

An angle measures 107.8° less than the measure of its supplementary angle. What is the measure of each angle?
Answer:
x=36.1
supplementary angle = 143.9 degrees
Step-by-step explanation:
angle: x
supplementary angle: 180-x
x = (180-x)-107.8
2x = 72.2
x = 36.1 degrees
180-x = 143.9 degrees
supplementary angle = 143.9 degrees
x measures 107.8 less than 180-x
x=180-x-107.8
x=72.2-x
Add x to both sides
2x=72.2
Divide both sides by 2
x=36.1
