Answer:
- Martin has 684 baseball cards
- Matt has 392 baseball cards
Step-by-step explanation:
Let N, J, K, M represent the numbers of cards that Martin, Josie, Kal, and Matt have, respectively.
<u>Equations</u>
We are told ...
N = 12J
J = 29 +K
M = 14K
K = 28
__
<u>Solution</u>
Working from the bottom up, ...
M = 14·28 = 392
J = 29 +28 = 57
N = 12J = 12·57 = 684
__
The answers to the questions asked are ...
Martin has 684 baseball cards; Matt has 392 baseball cards.
Answer:
x=-7
Step-by-step explanation:
Step 1: Simplify both sides of the equation.
x−(15x−6)=104
x+−1(15x−6)=104(Distribute the Negative Sign)
x+−1(15x)+(−1)(−6)=104
x+−15x+6=104
(x+−15x)+(6)=104(Combine Like Terms)
−14x+6=104
−14x+6=104
Step 2: Subtract 6 from both sides.
−14x+6−6=104−6
−14x=98
Step 3: Divide both sides by -14.
−14x/-14 = 98/-14
<u>x=-7</u>
