4(10n² - 2) - 5(8n² + 7) =
= 40n² - 8 - 40n² - 35 =
= 40n² - 40n² - 8 - 35 = -43 ← the end
Answer:
$3000
Step-by-step explanation:
I= PRT÷100
where,
I = interest = 900
T= 5
R/100 = 0.06
P = ?
I= PRT/100
900= P × 5 × 0.06
P = 900÷ 0.3
P= 3000
Answer:
x=11/2
Step-by-step explanation:
4+5x‒7=10+3x‒2
5x‒3=8+3x
5x‒3x=8+3
2x=11
2x/2=11/2
x=11/2
Answer:
x=-11, y=-5. (-11, -5).
Step-by-step explanation:
2y=2x+12
y=-2-3
-----------------
simplify 2y=2x+12 into y=x+6
y=-5
------------------
-5=x+6
x=-5-6=-11
