Giving 30 points Solve each system by substitution

Step-by-step explanation:

we substite y=2x+10 in the 2nd equation and get that 5x+5*(2x+10)=5. 5x+10x+50=5. 15x=-45. x=-3. y=2*(-3)+10=4

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet
