If m CDE=(3x+10)° m CDF=(x+25)°, and m EDF= 65°. Find m CDF
m∠CDF + m∠EDF = ∠CDE
[tex]x + 25° + 65° = 3x + 10[/tex]
[tex]x + 90° = 3x + 10[/tex]
[tex]90° = 3x + 10 - x[/tex]
[tex]90° = 2x + 10[/tex]
[tex]2x + 10 = 90[/tex]
[tex]2x = 90 - 10[/tex]
[tex]2x = 80[/tex]
[tex]x = \frac{80}{2} [/tex]
[tex]x = 40°[/tex]
m∠CDE
= 3 × 40 + 10
= 120 + 10
= 130°
Then , m∠CDF =[tex]x + 25 \\ = 40 + 25 \\ = 65°[/tex]
•°• m∠CDF = 65°there are 30 red marble and 150 blue marblee in a box what is the ratio of blue marblee tonred marbles

What value for x will show that lines / and m ar parallel?
Answer:
d. 60
Step-by-step explanation:
[tex](2x + 30) \degree = (4x - 90) \degree \\ (exterior \: alternate \: \angle s) \\ \\ 2x + 30 = 4x - 90 \\ \\ 30 + 90 = 4x - 2x \\ \\ 120 = 2x \\ \\ x = \frac{120}{2} \\ \\ x = 60[/tex]

Which of the following comparisons is correct?
-2 2
4<−4
−6< −5
================================================
Explanation:
Let's go through the answer choices
A) This is false because -2 is actually larger than -5. Make a number line and you'll see that -2 is to the right of -5. Numbers on the right are larger than numbers on the left. B) This is also false. The value 0 is smaller than 2. A number line might help show this.C) Also false. It should be 4 > -4. Any positive number is always larger than any negative number. D) This is true. On a number line, -6 is to the left of -5, so -6 is smaller than -5. This makes -6 < -5 a true statement.The height of the house is 35 feet. What is the height x of each story?

Which equation could be used to find the value of x?
Triangle DEF where angle E is a right angle. DE measures 55. EF measures x. Angle D measures 49 degrees.
cos 49° = x over 55
tan 49° = x over 55
cos 49° = 55 over x
tan 49° = 55 over x
The answer is tan 49° = x over 55 (I got it correct on my quiz).

Answer:
i believe its 300
Step-by-step explanation:
Answer:
Heres my guess on it, he can feed around 301 people
Step-by-step explanation:
I think you would first find out how much it would cost to feed 1 person, which can be done by taking 18.45/3. It will equal around $6.15. then you would take that number and divide by the money he is willing to spend, which is 1850
(1850/6.15)
You get 300.81 which can round to around 301 people

Alonso went to the market With $55 to buy eggs and sugar he knows he needs a package of 12 eggs that cost $2.75 after getting the eggs he wants to buy as much sugar as he can with his remaining money does sugar he likes comes in boxes that each cost $11.50
Given:
Alonso has total amount = $55
Cost of a package of 12 eggs = $2.75
Cost of sugar box = $11.50
To find:
The number of sugar boxes he can buy with the remaining money after buying a package of 12 eggs that cost $2.75.
Solution:
Let the number of sugar boxes he can buy be x.
Total cost of x sugar boxes = $11.50x
Total cost of x sugar boxes and a package of 12 eggs = $(11.50x + 2.75)
The total cost must be less than or equal to $55.
[tex]11.50x + 2.75\leq 55[/tex]
[tex]11.50x\leq 55-2.75[/tex]
[tex]11.50x\leq 52.25[/tex]
Divide both sides by 11.50.
[tex]x\leq \dfrac{52.25}{11.50}[/tex]
[tex]x\leq 4.54348[/tex]
So, the greatest integer value of x is 4.
Therefore, he can buy 4 sugar boxes with his remaining money.
