10 (2x + 3) = 15 x 9
20x + 30 = 135
20x = 135-30 = 105
x = 105 / 20 = 5.25
answer: x = 5.25
Answer:
(9,4)
Step-by-step explanation:
The given system is:
9x + 3y = 93
3x - 4y = 11
Multiply the bottom equation by 3 to get:
9x + 3y = 93
9x - 12y = 33
Subtract bottom equation from top one to get:
3y--12y=93-33
We put y-value into the bottom equation:
Put 12/100 and see how many times 100 can go into 300 and the number you multiplied multiply that number by 12.
Answer: yes!
Step-by-step explanation:
Answer:
3y^5(2y^3+3)=−6y^8−9y^5
−2c^6(5c^3+6)=−10c^9−12c^6
are the correct equations.
Step-by-step explanation:
If you simply all these equations you will get following equations :
when bases are same and are in multiplication we add the exponents.
−4b^4(5b^2+6)=−20b^6−24b^4
−5x^3(3x^3+2)=−15x^6−10x^3
−3y^5(2y^3+3)=−6y^8−9y^5
−2c^6(5c^3+6)=−10c^9−12c^6
so equation 3 and 4 are correct.
