Answer:

9

Step-by-step explanation:

Let corn tortillas be represented by c, flour tortillas be represented by f and the total number of packages be t

such that

t = c + f     .... eq 1

ratio of c to t = 7 : 16 = 7/16

Therefore, t = 16,    c = 7

substitute the value of t in eq 1

16 =  7 + f

f = 16 - 7

f = 9

Plums are 6 for $1.50, and a sign by the apples that are 5 for $3.00. What is the total cost of buying 2 plums and 2 apples?
Doss [256]

Answer:

The answer is $1.70

Step-by-step explanation:

If 6 plums are $1.50 you would divide $1.50 by 6 to get the unit cost, $.25. Then you do the same thing for the apples. $3.00 divided by the 5 apples is $.60. Now you need to multiply both unit costs by 2 then add them together to get $1.70

(plums)  $1.50 / 6 = .25

(apples) $3.00 / 5 = .60

(plums)  .25 x 2 = .50

(apples) .60 x 2 = $1.20

$1.20 + .50 = $1.70

Its fairly straightforward. Since the bottom equation only has one unknown,x, because y=1.3, you can plug y in and solve for x. Once you find the value of x, you then have the value for two variables, x and y, and again have one unknown coefficient a. To solve for the coefficient you just plug in your y value (1.3) and your x value (which can be rounded to 0.42). Using a little bit of algebra, you can then solve for a which should be a=2.108. I am not sure if your teacher wants you to solve it this way but you could also use the elimination method or substitution method that you would of learned when discussing system of equations. But no matter which way you do it, the math follows the rules. Hope this helps. I’d suggest you solve it yourself to double check my work.

Use substitution to solve the sy<br> 2x+3y = 19<br> x = 2y-1<br> Solve for x and y
svp [43]

Answer: Y=3, X=5

Step-by-step explanation:

2(2y-1) + 3y=19

4y-2+ 3y=19

7y=21

Y=3

Plug in y in the second equals

X=2(3) -1

X=6-1

X=5

Hope this helps!

Please help iam lost
Goryan [66]

Answer:

x = 4.

Step-by-step explanation:

I am assuming that you want to find the values of x and that WXYZ is a parallelogram.

In a parallelogram opposite sides are equal, therefore:

11x + 1 = 19x - 31

1 + 31 = 19x - 11x

32 = 8x

x = 32/8 = 4.
