  • Solving systems of equations using substitution/elimination

Step-by-step explanation:

<u>Step 1: Define Systems</u>

6x - y = -14

-2x + y = 6

<u>Step 2: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                    4x = -8
  2. Divide 4 on both sides:                   x = -2

<u>Step 3: Solve for </u><em><u>y</u></em>

  1. Define equation:                    -2x + y = 6
  2. Substitute in <em>x</em>:                       -2(-2) + y = 6
  3. Multiply:                                  4 + y = 6
  4. Isolate <em>y</em>:                                 y = 2

Dovator [93]

Answer:

0.42* 1265=x

Step-by-step explanation:

There are 1265 students in Cypress Middle School. So we already know one part of the equation. 42% of these students are in PE. So we know that 42% of  these 1265 students are in PE. Of these means you probably have to multiply 42% and 1265. 42% = 0.42. So to write an equation we take the 0.42 and 1265 and put it together. Therefore, 0.42 times 1265=x.

Fed [463]

Answer:

$1.51

Step-by-step explanation:

1.25 lb. of dried fruit  :  \frac{\$1.84}{lb.}*\frac{1.25\ lb.}{1}=\$2.30

0.5 lb. of cereal  :  \frac{\$2.38}{lb.}*\frac{0.5\ lb.}{1}= \$1.19

Cost = $2.30 + $1.19 = 3.49

Money = $5

$5 - $3.49 = $1.51 in change
