Answer:
56°
Step-by-step explanation:
1. the rule is: m(DCE)+m(DEC)+m(CDE)=180;
2. m(DCE)=180-(7x-2)=182-7x;
m(DEC)=180-(4x+33)=147-4x;
m(CDE)=180-(9x-31)=211-9x;
3. after the substitution all the angles (item 2) into the rule (item 1):
182-7x+147-4x+211-9x=180;
20x=360;
x=18;
4. if x=18, then filally, m(DCE)=182-7*18=56°.
what the common denominators for 1/4 + 1/2
Answer:
The common denominator is 4
Step-by-step explanation:
To answer this question of what is [tex]\frac{1}{4} +\frac{1}{2}[/tex]
We first have to find the LCM(Least Common Multiple) of the unlike denominators 4 and 2 which is 4
So we multiply the numerator and denominator [tex]\frac{1}{2}[/tex] by 2 so we can add with the same denominator [tex]\frac{1*2}{2*2}=\frac{2}{4}[/tex]
[tex]\frac{1}{4} +\frac{2}{4}=\frac{3}{4}[/tex]

what is the rate of change between the points 6,45 and 9,67.5
Answer:
7.5
Step-by-step explanation:
the slope m is a measure of the rate of change
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 45 ) and (x₂, y₂ ) = (9, 67.5 )
m = [tex]\frac{67.5-45}{9-6}[/tex] = [tex]\frac{22.5}{3}[/tex] = 7.5 ← rate of change

Hey there!
Guide #1
• 2 negatives = positive
• 2 positives = positive
• 1 negative & 1 positive = negative
• 1 positive & 1 negative = negative
Guide #2
• Negatives are BELOW 0
• Positives are ABOVE 0
Guide #3
• Positives are on the RIGHT side of 0 (and on the number line)
• Negatives are on the LEFT side of 0 (and on the number line)
Guide #4
• When dealing with negatives you go down
• When dealing with positives you go up
ANSWERING YOUR QUESTION
4 - (-19)
= 4 + 19
• You start with 19 (because it is the bigger number in this case) and go up 4 spaces to your right
= 23
Therefore, your answer should be: 23
Good luck on your assignment and enjoy your day!

Also [tex]\frac{20}{5}[/tex] simplified is 4 or [tex]\frac{4}{1}[/tex]
Find the angle measure ∠1 and ∠2
∠2 = 180° - (38° + 70°) [Angle Sum Property of Triangle....the 3 angles in a triangle sum up to 180°]
∠2 = 180° - 108°
∠2 = 72°
∠1 = 180° - 72° [linear pair/pair of supplementary angles...angles which form a straight line forms 180°]
∠1 = 108°

How many 1/4 cup servings of raisins are in 7/8 cups of raisins?
Answer:
7
Step-by-step explanation:
Divide 7/8 by 1/4. (You divide the "supply" of raisins into 1/4 cup "parts".)
[tex]\frac{7}{8} \div \frac{1}{4} = \frac{7}{8} \times \frac{4}{1} = \frac{28}{8} =\frac{7}{1} =7[/tex]
Multiply 7/8 by the reciprocal of 1/4 ("flip" the 1/4).
The result is 28/8, which can be simplified ("reduced") to 7.

A hot dog stand sells hot dogs for $4.25 and fries for $2.75. On monday, the stand sold 15 items and made $56.25. How many fries did they sell?
The number of fries sold is 5.
What is the equation that can be used to represent this situation?$4.25h + $2.75f = $56.25 equation 1
h + f = 15 equation 2
Where
h = number of hot dogs sold
f = number of fries sold
What is the number of fries sold?Multiply equation 2 by 4.25
4.24h + 4.25f = 63.75 equation 3
Subtract equation 2 from equation 3
7.5 = 1.5f
f = 5

make x the subject
x-5y=3v
Step-by-step explanation:
Simplifying
x + -5y = 3v
Solving
x + -5y = 3v
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '5y' to each side of the equation.
x + -5y + 5y = 3v + 5y
Combine like terms: -5y + 5y = 0
x + 0 = 3v + 5y
x = 3v + 5y
Simplifying
x = 3v + 5y
