Answer:
Step-by-step explanation:
9x+5y=35
Step 1: Add -5y to both sides.
9x+5y+−5y=35+−5y
9x=−5y+35
Step 2: Divide both sides by 9.
9x9=−5y+359
x=−59y+359
Answer:
x=−59y+359
Let's solve for x.
2x+5y=0
Step 1: Add -5y to both sides.
2x+5y+−5y=0+−5y
2x=−5y
Step 2: Divide both sides by 2.
2x2=−5y2
x=−52y
Answer:
x=−52y
Answer:
A. y - 4 = 3(x + 2)
Step-by-step explanation:
Point slope form is y - y1 = m(x - x1), where m is the slope and (x1, y1) is a point on the line
Plug in the slope and given point:
y - y1 = m(x - x1)
y - 4 = 3(x + 2) is the equation
So, A is the correct answer.
Hello,
Answer:
4,8
Step-by-step explanation:
<u>what would be 12% of 40 ? </u>
12% × 40 = 12/100 × 40 = 0,12 × 40 = 4,8
You can't make it proper.You can only simplify.
Step 1: Factor both the numerator and denominator down to prime factors:<span>62 = 2 * 31 </span>
40 = 23<span> * 5</span>Step 2: Calculate the greatest common factor, GCF (also called greatest common divisor, GCD), by taking all the common prime factors of the numerator and denominator, by the lowest powers:gcd(2 * 31; 23<span> * 5) = </span><span>2 </span>
Step 3: Divide both the numerator and denominator by their greatest common factor, GCF (also called the greatest common divisor, GCD):62/40 =
(2 * 31)/<span>(23 * 5)</span> =
<span>((2 * 31) : 2)</span> / <span>((23 * 5) : 2)</span> =
31/<span>(22 * 5)</span> =
31/20Step 4: Improper fraction, rewrite:<span>31 : 20 = 1 and remainder = 11 => </span>
31/20<span> = </span>(1 * 20 + 11)<span> / </span>20<span> = 1 + </span>11/20<span> = 1 </span>11/20<span> as a </span>mixed number (also called mixed fraction).<span>1 + 11 : 20 = 1.55 as a </span>decimal number<span>.</span>
