Solve the following system of equations. Enter the y-coordinate of the solution. Round your answer to the nearest tenth. 5x+2y=7
Rashid [163]
5x + 2y = 7....multiply by -3
-2x + 6y = 9
----------------
-15x - 6y = -21 (result of multiplying by -3)
-2x + 6y = 9
---------------add
-17x = - 12
x = 12/17 or 0.7

5x + 2y = 7
5(12/17) + 2y = 7
60/17 + 2y = 7
2y = 7 - 60/17
2y = 119/17 - 60/17
2y = 59/17
y = 59/17 * 1/2
y = 59/34 or 1.7 when rounded <====

How would I solve this?
Norma-Jean [14]

Answer:

AB = 1.33

Step-by-step explanation:

AB and QR are in a ratio of 3 to 8 so we can create this proportion:

(3x+5)/24 = 3/8

cross-multiply:

8(3x+5) = 72

divide each side by 8 to get:

3x + 5 = 9

3x = 4

x = 4/3 or 1.33 repeating

A grocer bought some walnuts for 45¢ per pound and some pecans for 60¢ per pound. He wants to mix the pecans and walnuts togethe
ladessa [460]
Cost of walnuts = 45 cents per pound
Weight of walnuts in mixture = x pounds

So, total cost of walnuts in the mixture = 45x
This gives the cost in cents. The cost in dollars will be = 0.45x

Cost of pecans = 60 cents per pound

Since total weight of the mixture is 90 pounds. The weight of pecans in the mixture will be (90 - x) pounds.

So, total cost of pecans in the mixture will be = 60 (90 - x)
This gives the cost in cents, the cost in dollars will be = 0.6 (90 - x)

x pounds of walunts and (90-x) pounds of pecans are mixed to produce a mixture to sell at 55 cents per pound. So,we can set up the equation for this case as:

Cost of Walnuts + Cost of Pecans = Cost of Mixture

0.45x+(90-x)*0.60=90(0.55)

Using this equation, we can find the weight of walnuts, using x we can also find the weight of pecans. From weights we can then calculate the cost of walnuts and pecans used in the mixture.
