4(x-7) = 0.3(x+2) + 2.11 the solution to the equation is

x=8.3

Step-by-step explanation:

4(x-7)=0.3(x=2)=2.11   Remove Parenthesis

4x-28=0.3x+0.6+2.11   Add the numbers

4x-28=0.3x+2.71   Move terms

4x-0.3x=2.71+28   Collect the like terms, Calculate the sum

3.7x=30.71   Divide both sides by 3.7

x=8.3, x=83/10, x=8 3/10

mr. flanders’ class sold 47 doughnuts and   mr. rodriquez’s class sold 38 cartons of milk

step-by-step explanation:

let x be the number of doughnuts sold by mr. flanders’ class and y be the number of cartons sold by mr. rodriquez’s class.

1. together, the classes sold 85 items, then

x+y=85.

2. both classes earn earned $104.49 for their school. if doughnuts were sold for $1.35 each, then x doughnuts costed $1.35x. if cartons of milk were sold for $1.08 each, then y cartons costed $1.08y. hence,

1.35x+1.08y=104.49.

3. solve the system of two equations:

a. turk and mcalister

b. howard, mission, and market

c. yes. since streets end some do not cross yet are not parallel to others. example: mcalister and 5th

step-by-step explanation:

parallel lines are lines which do not intersect ever and look a lot like railroad tracks. turk, mcalister and golden gate are examples of these.

intersect are streets which cross each other and a car on one can reach the other. howard, mission, and market intersect with 6th.

skew lines are lines which neither intersect nor are parallel. these lines exist here because some streets end and never intersect another like mcalister and 5th.
