X-5y=2 and 9x+8=15 solve by substitution

lozanna [386]

$x-5y=2$
Hence $x=2+5y$ (Equation I)
$9x+8=15$ (Equation II)
Substituting Equation I in Equation II
$9(2+5y)+8=15$
$18+45y+8=15$
$26+45y=15$
$45y=-11$
Hence $y= - \frac{11}{45}$

Substituting this in Equation in I to get X

$x-5(- \frac{11}{45} )=2$
$x+ \frac{11}{9}=2$
$x= 2- \frac{11}{9}$
$x= \frac{17}{9}$

What does the word “flip” tell you to do in “keep change flip” for dividing fractions a) change the place of the numbers numerat

mars1129 [50]

Answer:

b) change the places of the numbers in the numerator and the denominator for the second fraction

Step-by-step explanation:

In the phrase "keep change flip":

You "keep" the first fraction.

"Change" the division sign into a multiplication sign.

"Flip" (or switch) the places of the numerator and denominator in the second fraction.

Example:

$\frac{1}{2}$ ÷ $\frac{1}{3}$

$\frac{1}{2}*\frac{3}{1}=\frac{3}{2}=1.5$

Hope this helps.

Chris answered 61 out of 66 questions correctly on a test. What is his test average to the nearest thousandth

mars1129 [50]

If you divide 61 by 66, you will get .9242424. The thousandths place is the third number, so you base it off of the four number. If the fourth number is under 5, the third number stays the same and all numbers after it disappear. If the number is above 5, the third number rounds up 1 and the rest disappear. Because the 3rd number is 4 and the 4th number is 2, you will get the answer of .924
