Answer:

(x+1)+(x+2)+(x+3)=39

X+1+x+2+x+3=39

6+3x=39

3x=39-6

3x=33

X=33/3

X=11

Therefore, x+1 =11+1 =12

X+2 =11+2 =13

X+3 =11+3=14

Your, 3 consecutive intigers are 12,13,14

You can check your ans by adding them...

If you are helped with my answer pls tag me brianliest I really want it.... Plzz

THANK YOU............

A man sold a calculator at a loss of 12℅. If selling price was Rs.7040, what was the cost price?

Rashid [163]

Answer:

Rs.6195.20

Step-by-step explanation:

So first you need to find 12 % of Rs.7040. Thus:

$\frac{12}{100}$ × 7040 = 844.80

Then you subtract 844.80 from 7040 from which you get Rs.6195.20

Rs.6195.20 was the cost price.

ΔEFI is dilated by a scale factor of one third with the center of dilation at point F. Then, it is reflected over line a to crea

timofeeve [1]

Answer:

The correct option is;

Segment FE over 3 = Segment FH

Segment FI over 3 = Segment FG, and

Segment EI over 3 = Segment HG

ΔEFI ~ ΔHFG

Step-by-step explanation:

The given transformations are'

ΔEFI is dilated by a scale factor of 1/3 and then it is reflected over line a

By dilation, we have

FH = 1/3×FE

FG = 1/3×FI

HG = 1/3×EI

Also by reflection over a line, the relative positions of the y-coordinates of the points remain the same while the x coordinates changes sign such that an upright mirror image of the dilated triangle is formed

Therefore, since we have;

$\dfrac{sin\alpha}{sin\beta } \ and \ \dfrac{sin\gamma}{sin\alpha }$ the same for both triangles, that is given the following relation;

FG/FH = (1/3×FI)/(1/3×FE) = FI/FE

Then, ΔEFI is similar to ΔHFG (triangle similarity requirement AAA)

Hence, the correct option is that the

Segment FE over 3 = Segment FH

Segment FI over 3 = Segment FG, and

Segment EI over 3 = Segment HG

ΔEFI ~ ΔHFG.

The price of shirts in a store is $20 and the price of ties in the same store is $15. A customer buys 2 shirts and 3 ties during

Flauer [41]

First, find the new, discounted price of each item:
20 x 0.15 = 3 < this represents the discount for the shirts, which are now $17.
15 x 0.10 = 1.5 < this represents the discount for the ties, which are now $13.50.

If he buys 2 shirts @ $17, that gives us $34. 3 ties @ $13.50 gives us $40.50.

$34 + $40.50 = $74.50 < this is the discounted total price.
$20 (2) + $15 (3) = $85 < this is the original price.

Subtract the discounted price from the original: $85 - $74.50 = $10.50

Answer: The customer saved $10.50 due to sales.
