Identify a possible first step using the elimination method to solve the system and then find the solution to the system.
olchik [2.2K]

Answer:x = 1

y = 1

Step-by-step explanation:

The given system of simultaneous equations is expressed as

3x - 5y = - 2 - - - - - - - - - - - - 1

2x + y = 3 - - - - - - - - - - - - - 2

The first step is to decide on which variable to eliminate. Let us eliminate x. Then we would multiply both rows by numbers which would make the coefficients of x to be equal in both rows.

Multiplying equation 1 by 2 and equation 2 by 3, it becomes

6x - 10y = - 4

6x + 3y = 9

Subtracting, it becomes

- 13y = - 13

y = - 13/- 13 = 1

The next step is to substitute y = 1 into any of the equations to determine x.

Substituting y = 1 into equation 2, it becomes

2x + 1 = 3

2x = 3 - 1 = 2

x = 2/2 = 1

Jack and Jim sign up with an online music store. Jack chooses 15 downloads for $19.75, and Jim chooses 40 downloads for $43.50.
lina2011 [118]
The answer would be A. <span>The registration fee is $5.50, and the cost per download is $0.95.</span>

Solution
Let x = registration fee
y = cost/downloads

Jack
15y + x = 19.75 ; x = 19.75 - 15y
Jim
40y + x = 43.50

Thus,
40y + x = 43.50
40y + <span>19.75 - 15y = 43.50
</span>25y = 23.75
y= 0.95

for x,
<span>x = 19.75 - 15y</span>
x = 19.75 - 15( 0.95)
x= 19.75 -14.25
x = 5.5

Solve for xif mZRQS = 2x+4 and mZTQS = 6x+ 20.<br> 180<br> 19.5<br> -4<br> 90
Likurg_2 [28]

Answer:

x= -4

Step-by-step explanation:

2x+4=6x+20

so 2x-6x=20-4

divide both sides by -4

-4x/-4 = 16/4

=-4

to communication companies offer calling plans with company X it cost $0.35 to connect and then $0.05 for each minute with compa
Mama L [17]

Answer:

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y

Step-by-step explanation:

Given:

Cost of X company = \$ 0.35+(\$0.05\times 1 \ minute)

Cost of Y Company =\$ 0.15+(\$0.04\times 1 \ minute)

for n minutes

Cost of X company for n minutes = \$ 0.35+(\$0.05\times n \ minute)

Cost of Y Company for n minutes =\$ 0.15+(\$0.04\times n \ minute)

Difference for n minutes we get by Subtracting Cost of Y Company for n minutes by Cost of X company for n minutes

Difference for n minutes = (\$ 0.2+\$ 0.01n)=(0.2+0.01n)\times 10^2 \ cents

X Company charges (0.2+0.01n)\times 10^2 \ cents more than Company Y
