Hi! I need help with transversals of parallel lines solve the x if someone can help it would be great! Thank you!
Answers
25x = 30x - 15
Now simplify to solve for x.
25x-30x= -15
-5x = -15
Divide both sides by the coefficient of x (-5). The negative signs cancel, giving x= 3
Now to find the measure of angle KNH, simply substitute the value of x:
30(3)-15
90-15
= 75 degrees
Step-1: Find a property that shows the relation between the two angles
Given Information:
Line IJ and Line KL are parallel lines.∠KNH = 30x - 15∠GMJ = 25xIf Line IJ and Line KL are parallel lines (cannot intersect), both angles are outside the parallel lines, but each angle is on the opposite side of the transversal, the angles verify a property called the external angle property. The external angle property is called "external" because both angles are outside the transversal (a line that intersects the parallel line).
Step-2: Write an equation that describes the two angles
Since ∠KNH and ∠GMJ support the external angle property, we can assume that the two angles are equivalent. Therefore, we can write the following equation that can describe the relation between the angles:
⇒ ∠KNH = ∠GMJ ⇒ 30x - 15 = 25x
Step-3: Solve for x (common variable between two angles)
To find the measure of ∠KNH, we must find the value of x. This can be done by solving for the x-variable in the equation created from above knowledge. Simplify isolate all the variables on one side of the equation, simplify if needed, and isolate the coefficient if needed. We can isolate the variables on one side by adding or subtracting both sides of the equation. Then, we can cancel out the coefficient (a number being multiplied by the variable). from the variable by multiplying/dividing both sides of the equation.
⇒ 30x - 15 = 25x⇒ 30x - 15 - 30x = 25x - 30x (Isolating the variables on one side)⇒ -15 = 25x - 30x = -5x⇒ -15 = -5x ⇒ x = -15/-5 = 3Step-4: Substitute the value of x and determine the measure of ∠KNH
Now, we can substitute the value of x into the angle measure. We have the following angle measure of ∠KNH ⇒ (30x - 15)°. So, we have:
⇒ 30x - 15 = 30(3) - 15 = 75°Therefore, the measure of ∠KNH is 75°.

5 Michael has $16.25 in the bank. He needs $108 to buy a video game. He finds he can
save $1.75 a week from his allowance. How many weeks must he save in order to have
enough to buy the game?
Answers
Answer:
53 weeks (rounded)
Step-by-step explanation:
First, subtract 16.25 from 108 (108 - 16.25), resulting in 91.75
Next, you divide. 91.75/1.75
You would get 52.42... but you would have to add a week to actually get the game.

1. A ratio is an ordered pair of numbers a and b, written a / b where b does not equal 0. A proportion is an equation in which two ratios are set equal to each other
2. A unit rate describes how many units of the first type of quantity corresponds to one unit of the second type of quantity. A proportion is an equation that states that two ratios or rates are equivalent.
3. As defined in the lesson on Unit Rate and Proportionality, the unit rate is the rate of change in a relationship where the rate is per 1.
4. A proportion is an equation in which two ratios are set equal to each other. For example, if there is 1 boy and 3 girls you could write the ratio as: 1 : 3 (for every one boy there are 3 girls)

It is suitable to adjust both fractions to a common (equal, identical) denominator for adding, subtracting, and comparing fractions. The common denominator you can calculate as the least common multiple of both denominators - LCM(5, 4) = 20. In practice, it is enough to find the common denominator (not necessarily the lowest) by multiplying the denominators: 5 × 4 = 20. In the following intermediate step, it cannot further simplify the fraction result by canceling.
In other words - seventeen fifths plus twenty-one quarters is one hundred seventy-three twentieths.

Data set 1: Has a mean of 84 and a MAD of 6. Data set 2 Has a mean of 78 and a MAD of 8 I need to find out what the means to Mean Absolute Deviation (MAD) ratio is.
My teacher keeps telling me that it is 0.75, but I can't seem to get the right formula to it to answer right. can anyone help?
Answers
Answer:
0.75 or 6/8
Step-by-step explanation:
This is probably a late answer but I thought I would go ahead and respond.
When you have two data sets with the same variance, the ratio of the means to MAD is a way to test for the pooled variance of the two data sets
Given Data Set 1 with mean M1 and mean absolute deviation with MAD1 and another data set 2 with mean M2 and MAD2 the means to MAD ratio is given by the ratio of the absolute difference in means to the largest of the MADs
Here M1 = 84 and M2 = 78 so the absolute difference is |84-78| = 6
The larger MAD is MAD2 = 8
So the ratio is 6/8 = 3/4 = 0.75
Angie bikes for 20 minutes burning 150 calories. How many minutes will it take to burn 525 calories?
Answers
Answer:
70 minutes OR 1 hour and 10 minutes (it's the same thing)
Step-by-step explanation:
So this can be modeled by the equation 20/150=x/525
so solving for x, you have to say whats the most times that 150 will go into 525 without going over
the answer is 3
so 150x3=450 and 525-450=75
75 is one half of 150 so it would be 3.5
multiply 20 by 3.5 and you get 70 or 1 hour and 10 minutes since an hour is 60 minutes

Answer:
x < - 5Step-by-step explanation:
Given equation:
5 + x = nIf n is negative then we get:
n < 0 or5 + x < 0x < - 5If n is negative then x is less than - 5.
Example:
x = - 6 ⇒ 5 + (-6) = 5 - 6 = - 1 ⇒ -1 < 0Answer:
x < -5
Step-by-step explanation:
Now the value of x is,
→ 5 + x = n
→ x = n - 5
The value of n when negative,
→ n < 0 ---- {n = 0}
When n is a negative number,
→ x < 0 - 5
→ [ x < -5 ]
Hence, the answer is x < -5.
