Answer:
Angle 1 is 112°, 2 is 68°, 3 is 90°, 4 is also 90°, 5 is 22° and angle 6 is 158°
Step-by-step explanation:
To find angles 3 &4 and 2 &1, you subtract the measurement given in each intersection from 180 (all straight lines are 180) to find the other angle measurements. To find 5 I used the 4th angle and the 2nd angle to find the missing number out of 180 since all of the angles in a triangle have a sum of 180°. The missing angle was 22. You can use the angle measurement of #5 to find 6 like how I mentioned before about all straight lines equaling 180°. If this all sounds like mumbo-jumbo I can elaborate a little more in the comment section!
Answer:
-y = -2x - 3
Option 3
Step-by-step explanation:
When equations are equivalent, they will have infinitely many solutions.
If you want to find an equivalent equation, you can <u>multiply/divide every</u> term in the equation by the same number. You can also <u>rearrange</u> the equation.
Since the options mostly have "y" by itself, start by <u>rearranging</u> to isolate "y" in the given equation.
Move all the other numbers to the right of the equal sign except for "y". To move a number, apply its reverse operation to the entire equation.
Do reverse operations in reverse BEDMAS order.
2y - 4x = 6 Move "-4x" first. It's reverse is +4x.
2y - 4x + 4x = 6 + 4x
2y = 6 + 4x Move the "2" in 2y. Divide the whole equation by 2.
2y/2 = 6/2 + 4x/2
y = 3 + 2x Rearrange to look like the answer choices.
y = 2x + 3
This equation looks like option 3 except every term has a different negative/positive.
y = 2x + 3 -y = -2x - 3
We can <u>multiply every term</u> by -1.
y = 2x + 3
y*-1 = 2x*-1 + 3*-1
-y = -2x + (-3) Negative and positive make a negative
-y = -2x - 3 Same as option 3
Answer:
please mark brainliest ! It means that dilations map angles to angles, and the dilation preserves the measures of the angles. dilations. Dilations map lines to lines, rays to rays, and segments to segments.
Answer:
Length: 20 or 40 feet
Width: 40 or 20 feet
Step-by-step explanation:
Area = 800 = length*width = x*(60-x)= 60x - x^2
- x^2 + 60x - 800 = 0
x = 20
Or x = 40
So length can be either 20 feet or 40 feet and width can be 40 (60-20) or 20 (60-40)
Answer:
38 5/28
Step-by-step explanation:
Well start with the whole numbers 24 and 13 This is adding so that means everything has to be added together. 13+24=37 Now, lets go the fractions.
Find the LCD (Least Common Denominator) of 3/4 and 3/7 and rewrite to solve with the equivalent fractions. (remember the Denominator is the BOTTOM PART of the Fraction. Such as the 4 in 3/4.)
LCD = 28
21/28 + 12/28 = 33/28 which can be simplified to 1 5/28. Combining the whole and fraction parts 37 + 1 + 5/28 = 38 5/28 And that will be your answer. Another way you can do this is
converting mixed numbers to fractions Meaning put them in improper form where the numerator (the top number of a fraction is bigger than the denominator such as 4/3) , our initial equation becomes, 99/4 + 94/7
Applying the fractions formula for addition,
(99×7) + (94×4) / 4×7
= 693+376 / 28 =
= 1069/ 28
Simplifying 1069/28, the answer is
= 38 5/28
And one more thing. An easier way to make a mixed number a improper fraction is the multiply the denominator by the whole number then add the numerator and whatever the denominator is it stays for example
38 5/28.
28 times 38 = 1064 then add the 5 and you get 1069! But we aren't done yet, the denominator was 28 so that means the full answer is 1069/28 and that is the Improper fraction form!
Hope this helps! (sorry I took so long)
