Solve the simultaneous equations
x - 3y = -23
5x + 2y = 4
Answer:
(-2,7)
x= -2
y= 7
Step-by-step explanation:
We have
x-3y= -23
5x+2y=4
Let's solve this through substitution
let's start by adding 3y in the first equation
x= -23 +3y
plug this into the second one
5(-23+3y)+2y=4
-115+15y+2y=4
17y=119
y=7
Plug this y value into our first equation
x-3(7)= -23
x-21= -23
x= -2

What would 'x' be in the equation -3(x-2)=6?
Answer:
[tex]\boxed {\boxed {\sf x=0}}[/tex]
Step-by-step explanation:
To solve this equation, we must isolate the variable (x) using inverse operations.
[tex]-3(x-2)=6[/tex]
x-2 is being multiplied by -3. The inverse operation of multiplication is division, so we divide both sides by -3.
[tex]-3(x-2)/-3= 6/-3\\(x-2)=6 /-3 \\(x-2)= -2[/tex]
2 is being subtracted from x. The inverse operation of subtraction is addition, so add 2 to both sides of the equation.
[tex]x-2+2=-2+2\\x=-2+2\\x=0[/tex]
In this equation, x is equal to 0.

find the volume of the following square pyramid. geometry hw
Given:
The square base pyramid with height 3 cm and base edge 2 cm.
To find:
The volume of the square pyramid.
Solution:
Volume of a square base pyramid is:
[tex]V=\dfrac{1}{3}Bh[/tex] ...(i)
Where, B is the base area and h is the height of the pyramid.
Base is a square with edge 2 cm, so the base area is:
[tex]B=a\times a[/tex]
Where, a is the edge of the square base.
[tex]B=2\times 2[/tex]
[tex]B=4[/tex]
Putting [tex]B=4,h=3[/tex] in (i), we get
[tex]V=\dfrac{1}{3}(4)(3)[/tex]
[tex]V=4[/tex]
Therefore, the volume of the given pyramid is 4 cm³.

You have 2 shapes, a rectangle and a half circle.
Area of rectangle = 3 x 8 = 24
Area of a half circle = 1/2 x pi x r^2

Find the area of the polygon.
Answer:
A = 372 units²
Step-by-step explanation:
The area (A) of a trapezium is calculated as

And that point O is the center of the circle
[tex] \boxed{m\angle{BAC} \: = \: 57°} [/tex]
Explanation:
Because angle AOB is subtended by arc AB from point O.
Arc AB is equal to the measure of that angle.
Since arc ABC is subtended by the diameter, the arc is 180°.
