Answer:
Length of DE = 2.90 (Approx)
Step-by-step explanation:
Given:
AE = 7[tex]\frac{5}{8}[/tex]cm = 61 / 8 cm = 7.625 cm
AB = BC
CD = 1/2 cm = 0.5 cm
DE is 3/8 more than AB
Find:
Length of DE
Computation:
Assume;
AB = BC = x
So,
DE = x + 3/8(x) = [11 / 8]x = [1.375]x cm
AE = AB + BC + CD + DE
7.625 = x + x + 0.5 + [1.375]x
7.125 = 3.375 x
x = 2.1111 (Approx)
Length of DE = [1.375][2.111]
Length of DE = 2.90 (Approx)

Answer:
Angle LMO = 50°
Step-by-step explanation:
1) We need to solve for x.
We know angle LMN = 90°, and that angles LMO and NMO add up to angle LMN. That gives us this equation:
3x + 38 + 10x = 90
Now, we solve for x!
Combine like terms
13x + 38 = 90
Subtract 38 from both sides
13x = 52
Divide both sides by 13
x = 4
Now we know what x is.
2) Plug in x to angle LMO's given value (3x + 38)
3(4) + 38 = angle LMO
12 + 38 = angle LMO
50° = angle LMO
13. Find the value of x.
(5x + 2) (11x - 30)
I need help
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.

solve |x - 6| + 8 = 17
Answer:
x=15
Step-by-step explanation:
(x-6)+8=17 then remove unnecessary parentheses x-6+8=17 then calculate the sum x + 2 = 17 the move constant to the right hand side and change its sign x = 17 - 2 then subtract the numbers x=15 btw you should use photo math that's what I used
|x - 6| + 8 = 17
Subtract 8 from both sides.
|x - 6| + 8 - 8 = 17 - 8
|x - 6| = 9
Set x - 6 to 9 and -9, which leads to two cases.
x - 6 = 9
x = 9 + 6
x = 15
x - 6 = -9
x = -9 + 3
x = -6
Which is the answer?
Plug both values into the original absolute value equation to see which yields a true statement.
Let x = 15
|15 - 6| + 8 = 17
|9| + 8 = 17
9 + 8 = 17
17 = 17
Let x = -6
|-6 - 6| + 8 = 17
|-12| + 8 = 17
12 + 8 = 17
20 DOES NOT EQUAL 17.
Answer: x = 15
Renaldo will write StartFraction 3 over 20 EndFraction as a decimal. Which of the following methods should he use?
A:Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
B:Multiply the fraction by One-fifth to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
C:Multiply the fraction by StartFraction 33.3 over 33.3 EndFraction to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
D:Multiply the fraction by 33.3 to get a numerator of 100 and then write the denominator as hundredths using a decimal point.
Answer:
Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Option A is correct.
Step-by-step explanation:
Renaldo will write [tex]\frac{3}{20}[/tex] as a decimal.
We need to choose methods he should use.
To convert fraction into decimal we need to make denominator the multiple of 10
If we multiply 20 by 5 we get 100, so multiplying the given fraction [tex]\frac{3}{20}[/tex] by [tex]\frac{5}{5}[/tex] because we need to multiply both by numerator and denominator
So, [tex]\frac{3}{20}\\=\frac{3}{20}\times \frac{5}{5}\\=\frac{15}{100}\\=0.15[/tex]
So, Correct method will be: Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.
Option A is correct.
Answer:
it A. Multiply the fraction by StartFraction 5 over 5 EndFraction to get a denominator of 100 and then write the numerator as hundredths using a decimal point.

Which equation represents the line that passes through points (1,-5) and (3, -17)?
y=-6x+1
Oy - 6x + 1
y=-6x-1
O y=x-1
Need ASAP!!
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

7) Which equation below could be used to find the number of adult tickets that were sold. *
7 + 8x = 564
7x + 8x = 564
A + 3A = 564
A + 3 = 564
3A = 564
Answer:
A+3A=564
Step-by-step explanation:
As A is the no. of Adult tickets solds are denoted as 'A' and since the no. of Student tickets sold are 3 times of the adult tickets sold meaning 3 times A, denoted as 3A, when we sum them up, it equates to the total no. of tickets sold....

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?
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

Answer: 129
Step-by-step explanation:
work out the value of x
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°

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?
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.
