You can plug -x - 1 for y in the first equation
2x - (-x - 1) = 10
2x + x + 1 = 10
Combine
3x = 9
Divide
x = 3
Plug 3 for x in any equation ( I'll use th second equation )
y = - (3) - 1
y = - 3 - 1 = -4
x = 3 ; y = -4
(3, -4)
5 + 10 + 12 = 27 scores are less than 3
Answer:
Last Option
.
Step-by-step explanation:
In this question we will do the factors of given two terms then we will do the common factors of all the terms given in answer to match with.
Common factors of 36h³ = 1×2×2×3×3×h×h×h
Common factors of
= 1×2×2×3×h×h×h×h×h×h
In these two terms greatest common factor Of these two terms is = 1×2×2×3×h×h×h = 12h³
Therefore the third term will be the number which has the greatest common factor = 12h³
So the given terms are
6h³ = 1×2×3×h×h×h
12h² = 1×2×2×3×h×h
= 1×2×3×5×h×h×h×h
= 1×2×2×2×2×3×h×h×h×h×h
Therefore the greatest common factor of the term which matches with 12h³ is 
Answer:
an expression is numbers, symbols and operators (such as + and ×) grouped together that show the value of something and a equation is an equation says that two things are equal. (7+2=9) this is an equation
Answer:
300 in³
Step-by-step explanation:
By definition, volume of a pyramid,
= (Base Area x height ) / 3
= (90 x 10) / 3
= 900/3
= 300 in³
