I need Help Pleaseeee
Answer:
m∠C = 54°, m∠CDB = 100°
Step-by-step explanation:
in ΔABC, m∠A= 37° and m∠B = 89°
The sum of all 3 angles in any triangle is 180° so
m∠C = 180-37-89 = 54°
m∠CDB = 180-80 = 100° because any line has a 180°angle
2(6x+5)=58

What is the area of the triangle?
48 in 2
28 in 2
96 in 2
24 in 2
Answer:
48 in^2
Step-by-step explanation:
To find the area of a triangle is (1/2)*base*height, so (1/2)*4in*24in = 2in*24in = 48 in^2.
Answer:
48 in2
Step-by-step explanation:
when finding area we use the equation A= 1/2bh
b meaning base and h meaning height
so for this we would use A= 1/2(24)(4)
multiply them both to get A=1/2(96)
and then take half of 96 to get 48
so the answer is 48in 2

Choose the inequality that represents the following graph.
Answer:
im pretty sure its d
Step-by-step explanation:
what is the square root of 10 is the most possible and is 5 used to divide 25
Answer:
√10 = 3.162
Step-by-step explanation:
The square-root of 10 is;
√10 = 3.162
A number divided by 5 has its last digit as 0 or 5
In this case 25/5 = 5 and the √25 = 5

Two systems of equations are shown below:
System A
System B
3x + 2y = 3
−x − 14y = 1
−2x − 8y = −1
−2x − 8y = −1
Which of the following statements is correct about the two systems of equations? (1 point)
The value of x for System B will be one−third of the value of x for System A because the coefficient of x in the first equation of System B is one third times the coefficient of x in the first equation of System A.
The value of x for System A will be equal to the value of y for System B because the first equation of System B is obtained by adding −4 to the first equation of System A and the second equations are identical.
They will have the same solution because they represent the same lines when plotted on the coordinate axes.
They will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.
Answer:
The two linear equations represented in system A as :
3 x + 2 y =3 -------(1)
- 2 x - 8 y = -1 ------(2)
(1) × 2 + (2) × 3 gives
⇒ 6 x + 4 y - 6 x - 24 y = 6 -3
⇒ - 20 y = 3
⇒ y =
Putting the value of y in equation (1), we get
Two linear equation represented in system B is:
3. -x - 14 y =1
4. - 2 x - 8 y = -1
-2 ×Equation (3) + Equation (4)=
2 x +28 y- 2 x - 8 y= -2 -1
⇒ 20 y = -3
⇒y =
Putting the value of y in equation (3),we get
As Two system , that is system (A) and System (B) has same solution.
By looking at all the options , i found that Option (D) is correct. The two system will have the same solution because the first equation of System B is obtained by adding the first equation of System A to 2 times the second equation of System A.

if f(x)= x^2 and g(x) = 4f (x)-1 then which of the following is the value of g (-3)
view image below to see answer choices
Answer:
27Step-by-step explanation:
Given
f(x)= x^2-2 and g(x) = 4f (x)-1
g(x) = 4(x^2-2) - 1
g(x) = 4x²-8-1
g(x) = 4x²-9
Get g(-3):
g(-3) = 4(-3)²-9
g(-3 = 4(9) - 9
g(-3) = 36-9
g(-3) = 27
use the table to find the slope
-3(2x-3)= -5x+5 show your work
Answer:
x=4
Step-by-step explanation:
Hope this helps!
Plz, mark brainiest! ^.^
Answer:
x = 4
Step-by-step explanation:
Use the distributive property to distribute the -3 amongst the 2x and the -3 in the parenthesis. Once distributed you should have -6x + 9 = -5x + 5. Next, you want to get all like terms on the same side, and to do that you must swap the +9 and the -5x. When you swap these, you must 'flip' the sign and change 9 to -9 and -5x to 5x. Now the equation should look like this: -6x + 5x = -9 + 5.
Now just solve. After solving, it should look like this: -1x = -4. Now to get rid of the negatives. Just divide each side by negative one and your answer is x = 4.

Please help I really need it!! A student found out that 8% of the students in his school are left-handed.If there are 114 lefties, how many students are in his school?
Answer:
x = 1425
Step-by-step explanation:
Given that,
A student found out that 8% of the students in his school are left-handed.
Total no of lefties = 114
We need to find the total number of students in the school. Let they are be x.
ATQ,
8% of x = 114
[tex]\dfrac{8x}{100}=114\\\\x=\dfrac{114\times 100}{8}\\\\=1425[/tex]
Hence, there are 1425 students in the school.

A department store sells a pair of shoes with an 87% markup. If the store sells the shoes for $193.21 then what is their non-markup price?
Step-by-step explanation:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.
Answer:
87% + 100% = 187%
187% of original price = $193.21
100% of original price = $193.21 * (100/187) = $103.32.
The non-markup price is $103.32.

You are making a salad. The ratio of olives to croutons is 5 : 3. You put 12 croutons in your salad. How many olives do you put in your salad?
Answer:
20
Step-by-step explanation:
12/3 (the number of croutons) = 4
Since 4 is your base number, you would multiply 4 x 5.
20 olives
Answer:
20
Step-by-step explanation:
Ratio of olives : croutons is 5 : 3.
If you put 12 croutons, you put 4 times the amount of croutons in the ratio since 12/3 = 4.
That means you must also put 4 times the number of olives.
4 * 5 = 20
Answer: 20
