Step-by-step explanation:

9×2=18

18=54×0

18=54. since 0 times any number is equal to 0

then we just devide 18 and 54 and the answer will be 3.

At an ice cream parlor, ice cream cones cost $1.10 and sundaes cost $2.35. One day, the receipts for a total of 172 cones and su
antoniya [11.8K]
Let assume
X for ice cream cones
Y for sundaes
X+Y=172
X=172-Y……..*
1.10X+2.35Y=294.20
Substitute * in the above equation
1.10(172-Y)+2.35Y=294.20
189.2-1.10Y+2.35Y=294.20
1.25Y=294.20-189.2
1.25Y=105 divide both sides by 1.25
Y=84
The substitute Y value in * equation
X=172-84
X=88
Therefore
88 ice cream cones and 84 sundaes were sold!!

3x + 2y = 8<br> 5x + 2y = 12
Keith_Richards [23]

Answer:

Step-by-step explanation:

We can solve this in either of two ways.  I'll do both.

<u>Mathematically</u>

3x + 2y = 8

5x + 2y = 12

Rewrite either equation to isolate y.  I'll use

3x + 2y = 8

2y = 8 - 3x

y = (8-3x)/2

Now use this value of y in the other equation:

5x + 2y = 12

5x + 2((8-3x)/2) = 12

5x + (8 - 3x) = 12

2x = 4

x = 2

Use x=2 to find y:

y = (8-3x)/2

y = (8-3*(2))/2

y = (8-6)/2

y = 1

The point is (2,1)

<u>Graphically</u>

Graph the two equations and find the point they intersect.  See attachment.  

We obtain the same answer:  (2,1)

Please help me with this question!!!!
Komok [63]

Answer:

EH = 13 in

Step-by-step explanation:

Angle between a tangent and radius is right, that is

∠ EBH = 90° and so Δ EBH is right

Using Pythagoras' identity in the right triangle

EH² = BE² + BH² = 5² + 12² = 25 + 144 = 169 ( square root both sides )

EH = \sqrt{169} = 13

-  1

*୨୧ ┈┈┈┈┈┈┈┈┈┈┈┈ ୨୧*

♡ The Explanation/Step-By-Step ♡

- 6/100 + 5/100 + 80/100 + 9/100

Apply the fraction rule! --> a/c + b/c = a + b over c

6/100 + 5/100 + 80/100 + 9/100 = 6 + 5 + 80 + 9 over 100

Add the numbers: 6 + 5 + 80 + 9 = 100!

= 100/100 Apply the fraction rule! a/a = 1

a/a = 1 = 100/100 = 1
