Sam drew sticks and circles to solve this problem. Explain how he added. Then write the total.

Answers

"I"s are 10, "o"s are 1 and the total is 80

Solutions

We know that Sam drew sticks and circles to solve this problem. Lets see how he added. Lets use sticks to represent 47 and circles to represent 33.

|||| |||| |||| |||| |||| |||| |||| |||| |||| |||| |||| ||| = 47 sticks

ooooooooooooooooooooooooooooooooo = 33 circles

47 sticks + 33 circles = 80

Solve the Systems of equations algebraically 4x+5y=15
-4x+6y+7

Answers
A- (5/4, 2)
B- (2, 5/4)
C- (4/5,2)
D (2, 4/5)

Answers

STEP 1:
4x + 5y= 15
-4x + 6y= 7
add the two above equations; the x term cancels out; solve for y

11y= 22
divide both sides by 11

y= 2

STEP 2:
substitute the y value in step 1 into either original equation

4x + 5y= 15
4x + 5(2)= 15

4x + 10= 15
subtract 10 from both sides

4x= 5
divide both sides by 4

x= 5/4

ANSWER: (A) x= 5/4, y= 2 or (5/4, 2)
