Answer:
A number that can't be simplified to remove a square root (or cube root etc) is called surd .
There are six different types of surds, namely: Simple surds, Pure Surds, Similar Surds, Mixed Surds, Compound Surds, and Binomial Surds
y=3x - 5....(i)
6x+3y=15.....(ii)
Then,
Keeping value of y in (ii)equation;
or,6x+3(3x-5)=15
or,6x+9x-15=15
or,15x=15+15
or,x=30/15
:x=2
Now, <em>Keeping</em><em> </em><em>value</em><em> </em><em>of</em><em> </em><em>x</em><em> </em><em>in</em><em> </em><em>(</em><em>i</em><em>)</em><em> </em><em>equation</em><em>;</em>
<em> </em>y= 3x-5
or, y= 3×2 - 5
or,y= 6-5
: y=1
Answer:
1350 m³
Step-by-step explanation:
To find the volume of a rectangular prism, we have to multiply its length, width, and height together.
The dimensions of this prism are 9, 10, and 15.
9 · 10 · 15 = 1350
The volume is 1350 meters³.
I hope this helps ^^
X+y=5
x-y=3
x=3+y
(3+y)+y=5
2y+3=5
2y=2
y=1
x=4
The answer is 1 and 4
-12-18 = -30
answer = -30
You could even draw a number line and count from 18 to -12
