alekssr [168]

Answer:

The inequality to represent the situation is 20x\geq 3000 and the team must sell at least 15 "Jaguar Cards".

Step-by-step explanation:

Given: The ADMHS football team is trying to raise money to buy new equipment so the players are selling "Jaguar Cards" for \$20 each.

If the football team needs to raise at least \$3,000 for equipment.

To find: The inequality to represent the situation and the least number of "Jaguar Cards" the team must sell.

Solution:

Let the ADMHS football team sold x "Jaguar Cards" for \$20 each.

Now, the football team needs to raise at least \$3,000 for equipment.

So, the inequality to represent the situation is 20x\geq 3000.

Now, on solving we get,

20x\geq 3000

\implies x\geq \frac{300}{20}

\implies x\geq 15

Hence, the inequality to represent the situation is 20x\geq 3000 and the team must sell at least 15 "Jaguar Cards".

Solving equations:<br><br> (a) 5x - 9 = 3x + 3<br><br> (b) x + 6 = 34 - x
Jet001 [13]

Answer:

a) 5x - 9 = 3x + 3

5x - 3x = 3 + 9

2x = 12

x = 12 / 2

x = 6

b) x + 6 = 34 - x

x + x = 34 - 6

2x = 28

x = 28 / 2

x = 14

If AM = x + 8 and MB= 6x – 2, find MB.
IrinaK [193]

Answer:

10

Step-by-step explanation:

Firstly, AM=x+8

or, A=x+8-M......eqn (i)

MB=6x-2

or, B=6x-2-M......eqn (ii)

Now,

from eqn (i) and (ii)

x+8-M=6x-2-M

or, 8+2=6x-x-M+M

or, 10=5x

or, 10÷5=x

therefore, x=2

Again,

MB=6x-2

=6×2-2

=12-2

=10

is it correct
