3x+ 2y =-6

or, 3x= -(2y+6)

or, x= -(2y+6) ........... (ii)

3

from (i) and (ii),

7y-8 = -(2y+6)

4 3

or, 21y-24 = -8y-24

or,

y =

Answer:Pierre has $17 left

Step-by-step explanation:

Amount of money before dues = $42

according to the expression 42-d, d represents dues= $25

Amount left = Amount of money before dues - Amount of dues

                  = $42- $25

                  =$17

Pierre has $17 left after he spent $25 on dues.

Answer:

8. Not a function, the first three are of the same pattern but not the last two

9. Not a function, each input should have only 1 output or two inputs could have one output.

Answer:

by taking Hcf of 96 and 72 we get 4 so each team have 4

'24' teams can be made with each team having 4 girls and 3 boys.

Given that,

No. of girls = 96

No. of boys = 72

Since the number of teams is not given, we will find by finding out the GCF(Greatest Common factor) of 96 and 72.

96 = 2 * 2 * 2 * 2 * 2 * 3

72 = 2 * 2 * 2 * 3 * 3

GCF = 2 * 2 * 2 * 3 = 24

Thus, a maximum of 24 teams can be formed. The number of girls and boys in each of these teams would be:

No. of girls in each team = Total girls/no. of teams

= 96/24

= 4 girls

No. of boys in each team = Total boys/no. of teams

= 72/24

= 3 boys

Thus, each team will have 4 girls and 3 boys.

The answer is C

Number of days= 21/8

Step-by-step explanation:

The inequality to represent the given situation is [tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]. Therefore, option B is the correct answer.

Inequalities are the mathematical expressions in which both sides are not equal. In inequality, unlike in equations, we compare two values. The equal sign in between is replaced by less than (or less than or equal to), greater than (or greater than or equal to), or not equal to sign.

Given that, Joseph runs [tex]2\frac{1}{2}[/tex] miles on Monday. Each day after that, he runs the same [tex]1\frac{1}{3}[/tex] mile route every morning.

Let the number of days be x.

Here, the inequality is

[tex]2\frac{1}{2}+1\frac{1}{3} \le6[/tex]

Therefore, option B is the correct answer.

Answer:

After 7 weeks, Mia's office will have recycled 21 pounds.

Step-by-step explanation:

With the information provided, you can use a rule of three to find the pounds of paper that Mia's office will have recycled after 7 weeks given that they recycled 9 pounds over 3 weeks.

3 weeks  →  9 pounds

7 weeks  →         x

x=(7*9)/3

x=21

According this, the answer is that after 7 weeks, Mia's office will have recycled 21 pounds.

Answer: $2,000

Step-by-step explanation:

Gas is $3.25 per gallon. If Monica needs 12 gallons, cost would be:

= 12 * 3.25

= $39

If she wants to fill up for less than $35, she will have to earn the difference in points:

= 39 - 35

= $4

One can get $0.10 off for every $50 spent. The number of 10 cents in $4 is:

= 4 / 0.1

= 40

Monica would therefore have to spend:

= 50 * 40

= $2,000
