3 0

Answer:

(3)(c) + 43 ≥ 100

Step-by-step explanation:

Given:

Total number of friends = 3 friends

Number of card already have = 43

Total number of card at least want to collect = 100

Find:

Inequality

Computation:

Assume;

Same number of card each friend collect = c

Total number of card at least want to collect ≤ (Total number of friends)(Same number of card each friend collect) + Number of card already have

Total number of card at least want to collect ≤ (3)(c) + 43

100 ≤ (3)(c) + 43

(3)(c) + 43 ≥ 100

Beth normally cycles a total distance of 56 miles per week.
Vikki [24]

Answer:

She will cycle 85.169 miles in the third week.

(round if needed)

Step-by-step explanation:

56÷100=0.56 (this is 1%)

0.56 x 15 + 56 = 64.4 (you find 15% then add 56 (the original amount) because it's an increase of 15%)

repeat for the other 3 weeks

64.4÷100=0.644

0.644 x 15 + 64.4 = 74.06

74.06÷100=0.7406

0.7406 x 15 + 74.06 = 85.169

  • Addition Property of Equality

<u>Algebra I</u>

  • Terms/Coefficients
  • Coordinates (x, y)
  • Solving systems of equation using substitution/elimination

Step-by-step explanation:

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

3y = -5x - 3

y = -x + 1

<u>Step 2: Rewrite Systems</u>

Equation y = -x + 1

  1. [Multiplication Property of Equality] Multiply everything by -3:                   -3y = 3x - 3

<u>Step 3: Redefine Systems</u>

3y = -5x - 3

-3y = 3x - 3

<u>Step 4: Solve for </u><em><u>x</u></em>

<em>Elimination</em>

  1. Combine 2 equations:                                                                                   0 = -2x - 6
  2. [Addition Property of Equality] Add 6 on both sides:                                  6 = -2x
  3. [Division Property of Equality] Divide -2 on both sides:                              -3 = x

<u>Step 5: Solve for </u><em><u>y</u></em>

  1. Define original equation:                                                                               y = -x + 1
  2. Substitute in <em>x</em>:                                                                                                y = -(-3) + 1
  3. Simplify:                                                                                                           y = 3 + 1
  4. Add:                                                                                                                 y = 4
