Solve for x plzzzzzzzz
Answer:
x=5
Step-by-step explanation:
Since the two angle are corresponding, they have equal measure
therefore, 22x=110
now that we have produced an equation, solve for the value of x
22x/22 = 110/22
x=5
hope this helps :)
Answer:
22x=110° (corr angles)
x=110÷22

If B = x + 10 and C = x + 2 , find an expression that equals 2B + 2C in standard form.
Answer:
4x+24
Step-by-step explanation:

Using a set of numbers find the mean round to the nearest tenth median mode and range 8,6,3,7,1,6,5,6
Answer:
Mean 5.3, Median 6, Mode 6, Range 7
Step-by-step explanation:
First we arrange the numbers from smallest to the largest. (When you are done count them to see if you have the same amount of numbers that you had before you arrange them.)
1, 3, 5, 6, 6, 6, 7, 8
Mean: is the average of all the numbers :add all numbers / how many numbers we have
(1+ 3+ 5+ 6+ 6+ 6+ 7+ 8) /8 = 42/8 = 5.25 ≈5.3 (rounded to the nearest tenth)
Median: is average of the 2 numbers that are in the middle 1, 3, 5, 6, 6, 6, 7, 8
(6+6)/2 = 6
Mode: is the number that appears the most so is 6
1, 3, 5, 6, 6, 6, 7, 8
Range: is the difference between the highest and the lowest value
1, 3, 5, 6, 6, 6, 7, 8
8-1 = 7
Answer:
Mean- 42
Median- 6
Mode- 6
Range- 7

Step-by-step explanation:
x = price of pants
y = price of top
x + y = 36
x = (4/5)y
we use the second equation as substitute in the first
(4/5)y + y = 36
4y + 5y = 180
9y = 180
y = $20
x = (4/5)y = (4/5)×20 = 4×4 = $16

A scale model of a bus is 12 inches long. The scale is 1:21. How many inches long is the bus it
represents?
its 304.8 milimeter
The actual length of the bus that the scale model represents is 252 inches.
To find the actual length of the bus represented by the scale model, you can use the scale ratio.
Given:
Scale model length = 12 inches
Scale ratio = 1:21
Let "x" be the actual length of the bus.
Using the scale ratio:
Scale model length / Actual length = Scale ratio
12 inches / x inches = 1/21
Now, solve for "x":
x = 12 inches / (1/21)
x = 12 inches × 21
x = 252 inches
Therefore, the actual length of the bus that the scale model represents is 252 inches.
