(38 - 15) * 2 = c

c = original cards.

38 - 15 = 23

23 * 2 = 46

You started with 46 cards.

38 - 15 represents subtracting the cards you bought from the half of your original cards.

The * 2 represents multiplying the number of cards you had (without the new ones you bought) being multiplied by 2 (because you lost half of them).

WARRIOR [948]

Answer: 15 miles

Step-by-step explanation:

The equation is 5.25+1.25x=24 where x is each additional mile so to solve for x it would be  1.25x=18.75 and divide both sides to solve for x

What is the slope of the line through (-5, -3) and (-5, -7)?
Paul [167]

Answer:

The answer is undefined.

Step-by-step explanation:

Slope is found using this equation: y-y1/x-x1. Fill in the coordinates to this equation. It should now look like this. -7--3/-5--5. When subtracting from two negatives, it changes into a positive. For example, -7--3 becomes -7+3, which equals -4. The same thing applies for the second part. -5--5 becomes -5+5, which equals 0. So, your slope is -4/0. However, when a 0 is in the denominator, it becomes undefined. So, the answer is undefined.

Two stores are having a sale on T-shirts.Rose spends $63 for three T-shirts from store A and one from store B. Manny spends $140
Digiron [165]
Let a and b be store A and store B, respectively. Then:
3a+b=63
5a+4b=140
So
12a+4b=252
5a+4b=140
7a=112
a=16
b=15

Solve the systems of equations. <br>​
rewona [7]

Answer:

x = -1 and y = -1

Step-by-step explanation:

Solve 3x+3y=−6;−x+y=0

Steps:

I will solve your system by substitution.

−x+y=0;3x+3y=−6

Step: Solve−x+y=0for y:

−x+y+x=0+x(Add x to both sides)

y=x

Step: Substitutexforyin3x+3y=−6:

3x+3y=−6

3x+3x=−6

6x=−6(Simplify both sides of the equation)

6x

6

=

−6

6

(Divide both sides by 6)

x=−1

Step: Substitute−1forxiny=x:

y=x

y=−1

Answer:

x=−1 and y=−1
