Solve each word problem using a system of equations. show work ! #59 and #60.

#59)

Joe: 5a + 4b = 6 (1st)

Dawn: 3a + 6b = 6.3 (2nd)

Multiply 1st equation by 3 and 2nd equation by (-5) to eliminate a

15a + 12b = 18

-15a - 30b = -31.5

Add

-18b = - 13.5

b = 0.75

substitute b = 0.75 into 5a + 4b = 6

5a + 4(0.75) = 6

5a + 3 = 6

5a = 3

a = 0.6

Apple cost 60 cents each and banana cost 75 cents each

#60)

Wesley and Brian have total 87 baseball cards.

W + B = 87

Wesley has 30 less than twice as many as Brian

W = 2B - 30 (2nd)

So

W + B = 87

2B - 30 + B = 87

3B = 117

B = 39

W + 39 = 87

W = 48

Wesley has 48 cards and Brian has 39 cards

Hope they help.

infinitely many solutions

step-by-step explanation:

we have been given the equation;

2(2x + 3) = -4 + 2(2x + 5)

we need to determine the value of x.

2(2x + 3), we expand this expression to obtain 4x + 6

similarly 2(2x + 5) will become 4x + 10

now we have;

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 10 - 4

4x + 6 = 4x + 6

the expression on the left hand side is identical to the one on the right hand side. therefore, we are looking at just a single straight line whose equation is;

y = 4x + 6

consequently, we shall have infinitely many solutions

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.
