Answer:

(x, y) = (-3, -2)

Step-by-step explanation:

Perhaps this is a system of equations you want the solution for.

Since you have an expression for y, substitution is a viable approach.

5x +7(x+1) = -29 . . . . . . substitute for y

12x = -36 . . . . . . subtract 7 and simplify

x = -3 . . . . . . . . . divide by 12

y = (-3) +1 = -2 . . . use the expression for y

The solution is (x, y) = (-3, -2).

Answer:

The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.

Step-by-step explanation:

Given:

Number of caps in each pack = 3

Number of Shirts in each pack = 5

Total members of club = 45

Number of caps needed = 45

Number of shirts needed = 45

we have to find the least number of packs of caps and shirts that they need to buy in order to fulfill the needs of each member.

Solution:

Now we can say that;

number of packs of caps required can be calculated by Number of caps needed divided by Number of caps in each pack.

framing in equation form we get;

number of packs of caps required = $\frac{45}{3} = 15\ packs$

Also We can say that;

number of packs of Shirts required can be calculated by Number of Shirts needed divided by Number of Shirts in each pack.

framing in equation form we get;

number of packs of Shirts required = $\frac{45}5} = 9\ packs$

Hence The Science club would required 15 packs of caps and 9 packs of shirts to fulfill the needs of each member.

1. When x is 1, what value of y makes the equation true?

Mariana [72]

Answer:

Step-by-step explanation:

-0.5

Step-by-step explanation:

If x is 1, plug it into the equation.

So, y=-3(1) + 2.5

-3(1) = -3

now add.

-3+2.5 = -0.5

so that should give you y = -0.5
