6x+4/5=8
subtract 6x from both sides
4/5=8-6x
multiply both sides by 5 to get rid of the fraction
4=40-30x
divide both sides by 2
2=20-15x
add 15x to both sides
15x+2=20
subtract 2 from both sides
15x=18
divide both sides by 15
x=1.2
3<em>x</em> ² - 2<em>x</em> + 1 = 2<em>x</em> ² - 3<em>x</em> + 7
<em>x</em> ² + <em>x</em> - 6 = 0
(<em>x</em> + 3) (<em>x</em> - 2) = 0
<em>x</em> + 3 = 0 <u>or</u> <em>x</em> - 2 = 0
<em>x</em> = -3 <u>or</u> <em>x</em> = 2
Answer:
35
Step-by-step explanation:
It’s a 90 degree angle. 3x35=105 and 105-15=90
101.15
Explanation:
140 x 7.25% = 10.15
140 x 35% = 49
Then we add the tax and subtract the sale :
140 + 10.15 - 49 = 101.15$
Hope it’s right
