5.89/glove because to find the unit price of something you have to take the price ($29.45) divided by the amount of items (5 gloves) which gives you $5.89 = unit price
IT'S meep 4x – 10 = x2 – 5x + 10 ( y = 4x - 10 is substitute for y).................
PROOF: y + 5x = x²<span> + 10
</span> (4x - 10) + 5x = x² + 10
4x - 10 = x² -5x + 10
<span>
</span>0 = x2 – 9x + 20<span> (liked terms are grouped and simplified)....
PROOF: </span> 4x - 10 = x² -5x + 10
4x = x² -5x + 10 + 10
0 = x² -5x -4x + 20
0 = x² - 9x + 20
Solving:
x² - 9x + 20 = 0
x² - 5x - 4x + 20 = 0
(x - 5) (x - 4) = 0
⇒ x = 4 (as question says) OR x = 5......
Answer:
steps below
Step-by-step explanation:
5¹+5² = 30 30/<u>6</u> = 5¹
5³+5⁴ = 125 + 625 = 750 750/<u>6</u> = 125 = 5³
5⁵+5⁶ = 18750 18750/6 = 3125 = 5⁵
...........
(5¹⁹⁹¹+5¹⁹⁹²)/<u>6</u> = 5¹⁹⁹¹
sum of every couple consecutive multiple of 5 are multiple of 6, the sum
S= <u>5+ 5^2</u> + 5^3 + ...+ <u>5^1991 + 5 ^1992</u> IS multiple of 6
2x - 20 = 32
2x - 20 + 20 = 32 + 20
2x = 52
/2 = /2
x = 26
Answer:
3/6 or 1/2
Step-by-step explanation:
multiply 3*1/6=3/6
