Answer:
Okay, I haven't done this a long time however I believe with this you have to solve the equation by doing substitution.
Step-by-step explanation:
so, if f (x) equals 13, you replace the x in the equation to 13.
f(x)=-2x+5
f(x)=-2(13)+5
f(x)=26+5
f(x)=31
I believe 41 would be your answer. Hope this is right and it helped!
SAT Prep) In the figure, what is the value of x? A. 30° B. 50° C. 15° D. 20°
Answer:
D. 20° Can I get brainliest please :)
Step-by-step explanation:
You can see their is a 90° angle, and angles across from each other are equal so them together is 180° and you know the whole thing is 360° so you can do
360°-180°=180°
then you have the x's we still know that angles opposite each other are the same so if we add all those angles together we get
x+x+2x+30°+2x+30°
simplify it
6x+60°
then we know what we have left is 180° so we do numbers to numbers
180°-60°=120°
now we have
6x=120°
simplify it
x=20°
The value of x is 20°. Option b is correct.
Value of angle x is to be determine.
it can be defined as the measure of one line tilt over other line.
Here, the sum of angle is 180°
x+90+2x+30=180
3x =180-120
3x = 60
x = 20
Thus, the value of x is 20°.

Francisco and Stu were working on simplifying the following polynomial: 4x(2x-3)-5(3x-4). Write the equivalent expression that Francisco and Stu found for the polynomial in standard form?
Answer: 4x + 3x + 2x - 4 - 3
Step-by-step explanation: The numbers that have an X are considered major than normal numbers , when three numbers have the same X you put first the one that is major . Hope this helped.
The equivalent expression that Francisco and Stu found for the polynomial in standard form should be considered as the 4x + 3x + 2x - 4 - 3.
Calculation of the equivalent expression:Since the polynomial is 4x(2x-3)-5(3x-4)
Here the number that should have an X that should be relevant majorly as compared to the normal numbers so here the three numbers should be the similar also X we put first as major.
Therefore, The equivalent expression that Francisco and Stu found for the polynomial in standard form should be considered as the 4x + 3x + 2x - 4 - 3.

When the Widal antigen suspensions are mixed and incubated with the patient’s serum, anti salmonella antibodies present in the patient serum react with the antigen suspensions to give agglutination. Agglutination is a positive test result, indicating presence of anti-salmonella antibodies in the patient serum. No agglutination is a negative test result indicating absence of anti-salmonella antibodies.

on sunday Danielle is having her friends over for her 9th birthday she had 24 M&M bags 36 jelly beans and 48 snickers to make goodie bags If each person coming to her party received the same amount of each candy what is the greatest number of friends that can come over how much candy will they receive PLS help due in 20 minutes
Number of M&M bags with Danielle = 24
Number of jelly beans with her = 36
Number of snickers with her = 48
To find the highest number of candies each friend of Danielle will get, in a way in which all of them have the same number of candies , we have to find the HCF (highest common factor) of all the varieties of candy with Danielle.
Factors of 24 = 1,2,3,4,6,8,12,24
Factors of 36 = 1,2,3,4,6,9,12,18,36
Factors of 48 = 1,2,3,4,6,8,12,16,24,48
Highest common factor = 12
Which means the highest number of friends Danille can invite is 12 .
Number of M&M bags each friend will get :-
[tex] = 24 \div 12[/tex]
[tex]\color{hotpink} = 2 [/tex]
Which means each friend will get 2 M&M bags .
Number of jelly beans each friend of hers will get :-
[tex] = 36 \div 12[/tex]
[tex]\color{hotpink} = 3[/tex]
Which means each friend of Danielle will get 3 jelly beans.
Number of snickers each friend of hers will get :-
[tex] = 48 \div 12[/tex]
[tex] \color{hotpink}= 4[/tex]
Which means each friend of hers will get 4 snickers .
Therefore , the highest number of friends Danielle can invite = 12 and each of her friends will get 2 M&M bags , 3 jelly beans and 4 snickers .

A packaging company makes package peanuts in two containers, rectangular prisms and cylinders. The rectangular prism has a length of 6 feet, a width of 3 feet, and a height of 5 feet. The cylinder of peanuts has a diameter of 7 feet and a height of 10 feet. How many rectangular prisms contain the same amount of peanuts as one cylinder container? Round your answer to the nearest tenth.
Answer:
4.3
Step-by-step explanation:
length = 6 feet
width = 3 feet
height = 5 feet
Volume of rectangular prism = length × width × height
= (6 × 3 × 5) feet
= 90 cubic feet
cylinder of peanuts has a diameter of 7 feet and a height of 10 feet
Volume of a cyclinder = πr^2h
π = 3.14
r = diameter / 2
= 7/2 = 3.5 feet
h =10 feet
Volume of a cyclinder = πr^2h
= 3.14 × (3.5)^3 × 10
= 3.14 × 12.25 × 10
= 384.65 cubic feet
How many rectangular prisms contain the same amount of peanuts as one cylinder container = volume of cylinder container / volume of rectangular prism container
= 384.65 / 90
= 4.274
To the nearest tenth = 4.3
