Answer:
Part A: x + y = 36, 3x + y = 54
Part B: (9, 27), I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.
Step-by-step explanation:
Amount of Bean Packets: x
Amount of Frogs: y
We are given that:
x + y = 36
3x + y = 54
This is the answer to answer A.
To solve, use subtraction. Subtract:
3x + y - (x + y) = 54 - 36
3x - x + y - y = 18
2x = 18
x = 9
Substituting x = 9 into x + y = 36, we find that y = 27
In (x, y) form, substitute x = 9 and y = 27 to get (9, 27)
I used subtraction to solve the system, because it eliminated the "y" value, so it would be easiest to solve.

Can someone help me out, I will give out brainly.
Answer:
370
Step-by-step explanation:
Area of the entire thing is 20*20 = 400
You need to remove the triangle since it's not shaded, so find the area of the triangle and subtract it from the total (total = 400)
Area of triangle:
First find the height using pythagorean theorem
5*12 = 156
Then divide by two: 60/2= 30
400-30 = 370

For which value of x is the row in the table of values incorrect? The function is the quadratic function y = 5x2.
A. x = 3
B. x = 2
C. x = 0
D. x = 5
Answer:
A. x = 3
Step-by-step explanation:
0 times 5 = 0
2 times 5 = 10
3 times 5 = 15 then its 75
5 times 5 = 25 then its 125
it never equals to 45 for 3
you have to do it to the power of 2 for 3 and 5

Find the ratio of the given Sin A.
Answer:
5/13 ft
Step-by-step explanation:
If you remember that Sin is opposite over hypotenuse then the opposite of angle A is 5 and the hypotenuse is 13 so it would equal 5/13.
If 4x - 8 = 4 , find the value of x
Answer:
x=3
Step-by-step explanation:
4x-8=4
4x=12
4x/4=12/4
x=3
Answer:
x = 3
Step-by-step explanation:
Add 8 to both sides.
4x = 4 + 8
Simplify 4 + 8 to 12.
4x = 12
Divide both sides by 4.
x = 12 ÷ 4
Simplify 12 ÷ 4 to 3
x = 3

4x+2y=−14 y=−2x−6
Solve the system of linear equations:
Answer:
no solution
Step-by-step explanation:
solve by elemination
Answer:
No solutions
Step-by-step explanation:
4x+2y=−14
4x + 2(-2x - 6) = -14
4x -4x - 12 = -14
0x - 12 = -14
x = 0
y = 2(0) - 6
= 0 - 6
= -6

What is the sum of the interior angles of the polygon shown below?
Answer:
540°
Step-by-step explanation:
The sum of the interior angles of a polygon is
sum = 180° (n - 2) ← n is the number of sides
Here n = 5 , then
sum = 180° × 3 = 540°
Can someone explain how to do this? I keep getting it wrong
Answer:
Step-by-step explanation:
in order to find the measurements of all the angles you must find x and to find x you have to realize that the total sum of a triangle inner angles is 180 so you add all those together (48+x+x-44=180) and then if you solve that it gives you 2x+4=180 and then simplify 2x=176 and then x=88
then you plug x into the angles in order to find out the actual measurements
so a is obviously 48 but then b is equal to x which isequal to 88
and then for c it will be x-44 so its 88-44 which equals 44 and that is your answer
if you want to double check take all of your answers and see if they add up to 180
can someone please help
Answer:
for A
the law
V=Bh or V=πr2h
I will use this V=Bh
V= 16·21
V= 336cm³
For E
the law
A= 1/2·(A + B)·H
A= 1/2·(14 + 8)·4
A= 44cm²
V= A·H
V= 44·4
V= 176 cm³

Answer:
1) 25.12
2) ((4/3)*π*r^3)/2
Step-by-step explanation:
1) formula of the volume of a cylinder is: r^2 * π * h = 2/1 * π * 8 = 25.12
2) diameter = side of the square = 2r
so the radius is r
finally formula of the volume of a hemisphere: ((4/3)*π*r^3)/2

Roll needs to make a sauce mixture of 2/5 sand and 2/5 of clay and one for Pete Mas to put his plants yes 75 pounds of sand how many total pounds of soil rather have it he adds clay and Pete Moss to the sand to make the correction mixture
Answer:
187.5 pounds
Step-by-step explanation:
Fraction of sand = 2/5
Fraction of clay = 2/5
Fraction of peat = 1/5
Pounds of sand = 75
The total pounds of soil required to make Correct mixture : let that be x
Hence,
Using the sand Fraction and pounds which we know :
2/5 of x = 75
2x / 5 = 75
Cross multiply :
2x = 75 * 5
2x = 375
x = 375 / 2
x = 187.5
Required pond of sand =187.5 pounds
