A pair of reading glasses shows you an image of an object that is 3.1 times the object's actual size. So the scale factor of the

enlargement is 3.1. The photo shows the glasses magnifying the Constitution by a scale factor of 3.1. If the average text size was magnified at being a height of 0.8 inches, how big must the actual text size be (round to the nearest thousandth)?

laila [671]
Steps:
1. Multiply the first line by 3 and the second by 2
3(3x + 2y= 4)
2(8x -3y=-6)
2. New lines are
9x + 6y= 12
16x + -6y=-12
3. Now add/subtract them
25x + 0= 0
25x=0
4. Divide by 25
X=0

5. To find y, substitute the 0 in the x in one of the equations
9x + 6y= 12
9(0) + 6y= 12
6y= 12
6. Divide by 6, your Y=2
7. X=0, Y=2

Peter purchased 14 new baseball cards for his collection. This increased the size of his collection by 35%. How many baseball ca
Vlad [161]

Answer:

<em>Peter now has 54 baseball cards</em>

Step-by-step explanation:

<u>Percentages</u>

Assume Peter had x baseball cards in his collection. The 35% of his initial collection is

35 * x / 100= 0.35x

We know that those 14 new baseball cards represent a 35% of his previous collection, therefore we can set a simple equation

0.35x=14

When we solve for x, we'll know how many baseball cards Peter had before

x=14 / 0.35 = 40

Peter had 40 cards, he added 14 new baseball cards, so he now has 40+14=54

Peter now has 54 baseball cards
