13. Find the value of x.
(5x + 2) (11x - 30)
I need help
Answers
Answer:
x=13
Step-by-step explanation:
5x+2+11x-30=180 (co-interior angles add to 180)
16x-28=180
16x=208 (divide both sides by 16)
x=13
The measure for x is 13.
What are Co- interior Angles?Co-interior angles are located on the same side of a transversal and between two lines. The two marked angles in each diagram are referred to as co-interior angles. Co-interior angles are supplementary if the two lines are parallel since they add to 180 degrees.
Given:
Angles are (5x+2) and (11x- 30).
So, 5x+2+11x-30=180 (co-interior angles add to 180)
16x-28=180
16x=208
x=13
Hence, the measure for x is 13.

work out the value of x
Answers
Answer:
117 degrees
Step-by-step explanation:
So we already know that one angle is 38 degrees, so we have that one. The angle, 101 is exterior, and we have to subtract 180 from that to get the interior angle. We get a difference of 79. Since the sum of a triangle's interior angles are 180, we have to add 38+79 to get 117. Then, we have to subtract it from 180 to get the value of the interior angle as 63 degrees. Because x is on the outside, we have to again subtract 63 from 180 to get the missing value of x as 117.
180° - 101° = 79°
180° - (38° + 79°)
180° - 117° = 63°
180° - 63° = 117°
x = 117°

Joe pushes a box with a force of 16 N to the left. Ann pushes the same box from the opposite side with a force of 10 N to the right. What will be the result?
Answers
Answer:
the box will move to the left with a force of 6 N
Step-by-step explanation:
Given that:
Force exerted on the box to the left (F1) = 16N
Force exerted on box towards the right (F2) = 10N
Since the forces are a ting in opposite Direction :
Net force :
F1 - F2
16N - 10N = 6N
The net force will be the direction of the greater applied force :
Hence, the box will move to the left with a force of 6 N

Dr. Betz, a vet, is running a free rabies clinic. He estimates that it will take him 12 minutes for each animal he treats. Dr. Betz has already seen 20 animals, the last of which was a shaggy dog. Write an equation for how many minutes Dr. Betz worked. How long did Dr. Betz work at the rabies clinic if he saw 20 more animals after the shaggy dog?
Answers
Answer:
equation: y = 12x
Dr. Betz worked for 8 hours.
Step-by-step explanation:
To write the equation we'll use the form y = mx, where y represents the amount of time the Doctor worked, m is the amount of minutes it takes to treat each animal, and x is how many animals have been treated. We know the value of m is 12, so let's put that into the equation:
y = 12x
Now we have our equation. We can use it to see how long Dr. Betz worked. He treated a total of 40 animals - 20 including the shaggy dog, and 20 after the shaggy dog. let's replace x with 40:
y = 12(40)
Now solve:
y = 480
Dr. Betz worked for 480 minutes. There are 60 minutes in an hour. Divide 480 by 60 to find out how many hours Dr. Betz worked for:
480/60 = 8
Dr. Betz worked for 8 hours.

y=-6x-1
O y=x-1
Need ASAP!!
Answers
Answer:
The equation y = -6x + 1 represents the line ⇒ A
Step-by-step explanation:
The form of the linear equation is y = m x + b, where
m is the slopeb is the y-interceptThe rule of the slope is m = [tex]\frac{y2-y1}{x2-x1}[/tex] , where
(x1, y1) and (x2, y2) are two points lie on the line∵ The line passes through points (1, -5) and (3, -17)
∴ x1 = 1 and y1 = -5
∴ x2 = 3 and y2 = -17
→ Substitute them in the rule of the slope to find it
∵ m = [tex]\frac{-17--5}{3-1}[/tex] = [tex]\frac{-17+5}{2}[/tex] = [tex]\frac{-12}{2}[/tex] = -6
∴ m = -6
→ Substitute it in the form of the equation above
∴ y = -6x + b
→ To find b substitute x by 1 and y by -5 in the equation
∵ -5 = -6(1) + b
∴ -5 = -6 + b
→ Add 6 to both sides
∴ 1 = b
→ Substitute it in the equation
∴ y = -6x + 1
∴ The equation y = -6x + 1 represents the line

A flat rectangular piece of aluminum has a perimeter of 62 inches. The length is 15
inches longer than the width. Find the width.
Answers
Answer:
Width of rectangular piece = x = 8 inches
Step-by-step explanation:
Perimeter of rectangular piece = 62 inches
Let width of rectangular piece= x
and length of rectangular piece = x+15
We need to find width i.e value of x
The formula used for perimeter of rectangle is: [tex]Perimeter=2(Length+Width)\\[/tex]
Putting values in formula and finding Width:
[tex]Perimeter=2(Length+Width)\\\\62=2(x+x+15)\\62=2(2x+15)\\62=4x+30\\62-30=4x\\4x=32\\x=\frac{32}{4}\\x=8[/tex]
After solving we get value of x = 8
So, Width of rectangular piece = x = 8 inches
