This is quiet simple. i like to use a method my math teacher calls "plug and chug". we know that y= 4x +2
some people call this the substitution method but it has the same concept. now that we know what y equals, we plug it into teh equation:
(4x+2) -x=17
then we "chug it":
4x+2-x=17
then we have to isolate x. add the x's:
5x+2=17
in order to isolate x subtract 2 from both sides:
5x=15
now to isolate again divide both sides with 5:
x=3
so x is 3. bow we plug that into what y is;
y=4 (3) +2
y=14
so:
x=3
y=14
(to double check plug and chug into the first question . if x and y are correct, you will get 17)
Answer:
27 cm
Step-by-step explanation:
every side of a cube is equal to each other. the formula for volume is LxWxH, so 3*3*3=27
Answer:
Yes it is perfect square trinomial.
The area of a square is equal to length times width, which are the same.
200= x^2
Root both sides
x= root 200
x= approx. 14.1
Final answer: 14.1 ft
Answer:
1/2
Step-by-step explanation:
Die : 1,2,3,4,5,6
Less than 4: 1,2,3
P (less than 4) = Number of options less than 4/ total
= 3 /6
=1/2
