The answer to number 5 is 16 because if 1/8 goes per bag then every one pound is stretched into eight bags and you multiply by two for the two pounds and get 16 bags for number six you just divide 1/4 by 3 and get 0.0833 pounds per child

Solve the system of equations.<br> – 9y + 4x – 11 = 0<br> - 3y + 10x + 31 = 0
Kruka [31]

value of x =-4 and value of y=-3

(-4,-3) is the solution of system of equations.

Step-by-step explanation:

We need to solve the system of equations

-9y + 4x-11 = 0- 3y + 10x + 31 = 0

Rearranging:

-9y + 4x = 11\,\,\,eq(1)\\- 3y + 10x=- 31 = 0\,\,\,eq(2)

Multiply eq(2) with 3 and subtract eq(2) from eq(1)

-9y + 4x = 11\\-9y+30x=-93\\+\,\,\,\,\,\,-\,\,\,\,\,\,\,\,\,\,\,\,+\\----------\\-26x=104\\x=\frac{104}{-26}\\x=-4

Putting value of x = -4 into eq(1)

-9y + 4x = 11\\-9y+4(-4)=11\\-9y-16=11\\-9y=11+16\\-9y=27\\y=\frac{27}{-9}\\y=-3

So, value of x =-4 and value of y=-3

(-4,-3) is the solution of system of equations.

I need help with this question can anyone help ?
Fofino [41]

Answer:

m < 1 = 72

Step-by-step explanation:

Since we know that line l and line m are parallel and that p is one of their transversals, it sets up a situation where we can identify which angles are congruent (equal) to one another according to their positions.

In this case, we can see that < 3 and < 1 are in the same matching corners created by the transversal. When angles are in the same matching corners they are called corresponding angles - and according to the Corresponding Angles Postulate, corresponding angles are congruent.

Therefore, m < 3 = m < 1, and since it's given that  m < 3 = 72, we know that m < 1 = 72 too.
