Y=mx+b is the equation used to solve.
y>x+3 So start on b which in this case is 3, meaning plot the first point on 3. Then you move with x by using rise over run. also shown as rise/run. This means you would rise on the Y-axis using the value before x (also known as m) because there isn't one in this inequality that means we would go up one. Then you run to the right 1 because below the x is a 1. Because this is a greater then sigh you would shade above the line with a dotted line because it isn't equal to. Now try to do the next one on your own and tell me how you do.

Solve: <br>x + y = 7<br>3x - 2y = 11<br><br>By using Substituting method.

Salsk061 [2.6K]

$\large\underline{\sf{Solution-}}$

$\sf \longmapsto x + y = 7 \: \: - - - (i)$

$\sf \longmapsto 3x - 2y = 11 \: \: - - - (ii)$

<u>By first equation,</u>

$\sf \longmapsto x + y = 7$

$\sf \longmapsto x = 7 - y$

<u>Now, we can find the original value of y.</u>

$\sf \longmapsto 3x - 2y = 11$

$\sf \longmapsto 3(7 - y) - 2y = 11$

$\sf \longmapsto 21 - 3y - 2y = 11$

$\sf \longmapsto 21 - 5y = 11$

$\sf \longmapsto - 5y = 11 - 21$

$\sf \longmapsto - 5y = - 10$

$\sf \longmapsto y = \dfrac{ - 10}{ - 5}$

$\sf \longmapsto y = 2$

<u>Now, we can find the original value of x.</u>

$\sf \longmapsto x + y = 7$

$\sf \longmapsto x + 2 = 7$

$\sf \longmapsto x = 7 - 2$

$\sf \longmapsto x = 5$

Therefore, the values of x and y are 5 and 2 respectively.

51% of the tickets sold at a school carnival were early-admission tickets. If the school sold 100 tickets in all, how many early

saul85 [17]

Answer:

51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Step-by-step explanation:

Total number of tickets sold by = 100

Let $x$ be the early-admission tickets sold by the school.

As 51% of the tickets sold at a school carnival were early-admission tickets.

so

$x=\frac{51}{100}\times 100$

$= 51$

Therefore, 51 were the total number of the tickets sold at a school carnival were early-admission tickets.

Bill paid $2.49 for 5 pounds of rice. What could be cost of 9 pounds

Nadya [2.5K]

Answer:

$\boxed{\sf Cost \ of \ 9 \ pounds \ rice =\$ 4.482}$

Given:

5 pounds rice cost $2.49

To Find:

Cost of 9 pounds rice

Step-by-step explanation:

5 pounds rice cost $2.49

1 pound rice will cost $ $\sf \frac{2.49}{5}$

So,

9 pounds rice cost = 1 pound rice cost × 9

= $ $\sf \frac{2.49}{5} \times 9$

= $0.498 × 9

= $4.482
