Answer:

Mrs baxter has $1.70

Step-by-step explanation:

1 dollar = 1.00

2 quarters = 0.50

1 dime = 0.10

2 nickels = 0.10

1.00 + 0.50 + 0.10 + 0.10 = 1.70

Answer:

3x+4y

Step-by-step explanation:

If you buy 2 M&Ms, you would get $6. Plugging in 2 for x would indeed give us 6, which makes sense.

If you buy 2 KitKats, you would get $8. Plugging in 2 for y would indeed give us 8, which makes sense.

Therefore, we can plug in x and y for the unknowns and add them together to find the total amount spent on both candies.

Answer:

(3, 5)

Step-by-step explanation:

Use the equation already isolated and plug it into the other equation

3x + 2( x t 2)= 19

solve for x

3x + 2x +4 = 19

5x= 19-4

5x= 15

x= 15/5

x=3

Now plug x (3) into one of the equations to find y

y= 3 + 2

y= 5

Put it in (x, y) form, (3, 5)

Answer:

[tex]A=522.97\ \text{cm}^2[/tex]

Step-by-step explanation:

Given that,

The diameter of the cylinder, d = 8 cm

Radius, r = 4 cm

Height of the cylinder, h = 16.8 cm

We need to find the surface area of this cylinder. The formula for the surface area of the cylinder is given by :

[tex]A=2\pi r^2+2\pi rh\\\\=2\pi r(r+h)\\\\=2\times \dfrac{22}{7}\times 4\times (4+16.8)\\\\=522.97\ \text{cm}^2[/tex]

So, the surface area of the cylinder is [tex]522.97\ \text{cm}^2[/tex]

Step-by-step explanation:

Hey there!

According to the question,

Let the unknown number be x (smaller) another number be y (greater) respectively.

1st condition: One number is 7 more than twice of another number.

(i.e y = 2x+7)....... (i)

2nd condition: The sum is 22.

(i.e X+y= 22)……(ii)

From equation (ii).

x+ y= 22

x= 22-y

Putting the value of X in eqaution (I)

y = 2(22-y)+ 7

y = 44 - 2y +7

3y = 44+7

y = 51/3

Therefore, y= 17.

Now, Putting the value of y in eqaution (ii)

X = 22-y

x = 22-17

Therefore, x= 5.

Therefore, one number is 17. (Option D).

Hope it helps....

Step-by-step explanation:

3 books times 6 dollars each = 18 dollars.

21 minus 18 dollars = 3.

Answer:

x = 4

x = 1

Step-by-step explanation:

hey there,

< When you have these kinds of problems:

[tex]\frac{2}{6} = \frac{x}{12}[/tex]

There's a really easy way to solve it. Multiply the two that are across from each other. That means 2 x 12. It couldn't be 6 x [tex]x[/tex] because this one has x in it so it won't work. So you multiply them: 2 x 12 = 24. Then you divide that number by the last number available. The last number that hasn't been used yet is "6" (we have used 2 and 12). So we divide 24/6.

24/6 = 4

x = 4 >

Answer:

$87.20

Step-by-step explanation:

The one above is incorrect, It showed up as wrong for me! The correct answer is $87.20

The sales price of the outfit is $87.2.

The correct option is (2).

A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.

Given:

Kendra is buying an outfit that is on sale for 20% off.

The original price of the outfit is $109.

The discount,

= 20% of 109

= 20 x 109 / 100

= 21.8

The sales price,

= 109 - 21.8

= 87.2

Therefore, the price is $87.2.

Answer:

The answer is below

Step-by-step explanation:

a) Let y represent the amount of time kiran slept, hence:

y = x - (1/10)x = x - 0.1x

y = 0.9x

b) Let y represent the amount of time Mia practice, hence:

y = x - (2/5)x = x - 0.4x

y = 0.6x

c) Let y represent the amount of drink kiran drank, hence:

y = x + (4/3)x = 7x / 3

y = 7x/3

d) Let y represent the money Mai spent, hence:

y = x - (1/4)x  = x - 0.25x

y = 0.75x

e) Let y represent the amount of almond kiran ate, hence:

y = x + 1.5x = 2.5x

f) Let y represent the recycling Mai collected, hence:

y = x - (3/10)x = x - 0.3x

y = 0.7x

g) Let y represent the amount of km kiran walked, hence:

y = x + (3/8)x

y = (11/8)x

h) Let y represent the amount of puzzles mai completed, hence:

y = x + (3/5)x = x + 0.6x

y = 1.6x
