Jackson has three cartons of gumballs. There are 100 boxes in each carton. There are 100 gumballs in each box

Answer:

3. 10000

Step-by-step explanation:

Given the following :

Number of gumball cartons = 3

Number of boxes per carton = 100

Number of gumballs per box = 100

The number of gumballs can be expressed in the form : (a. 10) ; where ; a = prime number ; b = whole number

Values of a and b?

Total number of gumballs :

Number of carton × number of boxes per carton × number of gumballs per box

3 × 100 × 100

Hence, writing the expression in the form: a. 10

a. 10 = 3 × 10000

20 points!! Solve this system of lineal equations.separate the x- and y- values with a comma

Zielflug [23.3K]

Solve the following system:{12 x = 54 - 6 y | (equation 1)-17 x = -6 y - 62 | (equation 2)
Express the system in standard form:{12 x + 6 y = 54 | (equation 1)-(17 x) + 6 y = -62 | (equation 2)
Swap equation 1 with equation 2:{-(17 x) + 6 y = -62 | (equation 1)12 x + 6 y = 54 | (equation 2)
Add 12/17 × (equation 1) to equation 2:{-(17 x) + 6 y = -62 | (equation 1)0 x+(174 y)/17 = 174/17 | (equation 2)
Multiply equation 2 by 17/174:{-(17 x) + 6 y = -62 | (equation 1)0 x+y = 1 | (equation 2)
Subtract 6 × (equation 2) from equation 1:{-(17 x)+0 y = -68 | (equation 1)0 x+y = 1 | (equation 2)
Divide equation 1 by -17:{x+0 y = 4 | (equation 1)0 x+y = 1 | (equation 2)
Collect results:Answer: {x = 4 {y = 1

Please note the { are supposed to span over both equations but it interfaces doesn't allow it. Please see attachment for clarification.
