The actual answer is -9.

7-|-23| + |-7|

Simplify -23 to 23 since absolute values are ALWAYS positive. Then simplify -7 to 7.

Your expression should look like this :

7-23+7

Now add it together and you should get -9

If ANQZ - ACBK, find BK. * O BK = 39 O BK = 16 O BK = 65 O BK = 27

patriot [66]

9514 1404 393

Answer:

Step-by-step explanation:

Corresponding sides are proportional in similar triangles, so ...

ZT/ZQ = KF/KB

27/(2x +7) = 45/(4x+1)

27(4x+1) = 45(2x +7) . . . cross-multiply

3(4x +1) = 5(2x +7) . . . . divide by 9

12x +3 = 10x +35 . . . . . eliminate parentheses

2x = 32 . . . . . . . . . . . . . subtract 10x+3

x = 16 . . . . . divide by 2

Then the length of BK is ...

BK = 4x+1 = 4·16 +1

BK = 65

Type the correct answer in the box. Use numerals instead of words.

Mandarinka [93]

Answer:

Step-by-step explanation:

We are here given a modulus expression and we need to find out the value when m = -5 and n = 3 .

Modulus :- It always gives positive value . For example ,

$\rm\implies |-a| = a$

$\rm\implies |a| = a$

The given modulus expression is :-

$\rm\implies |m^2+ n^2|$

As the number inside the modulus operator are already squared therefore they will always give positive value for real numbers . Here we can omit the modulus .

$\rm\implies m^2 + n^2$

Plug in the given values ,

$\rm\implies (-5)^2 + 3^2$

Solve 5² and 3² and add them ,

$\rm\implies 25 + 9$

On adding ,

$\rm\implies 34$

Therefore ,

$\rm\implies \boxed{\blue{\rm |m^2+n^2| = 34 }}$

Hence the required answer is 34 .

Melvin Marshall bought 20 Mothers Day Muffins for Mama-Melanie, Auntie-Marlene, Grandma-Melissa, Cousin Carmela and Sister-Shami

amid [387]

Answer:

The number of Carmel muffins is 8 and the number of lemon muffins is 12.

Step-by-step explanation:

Melvin Marshall bought a total of 20 Muffins . Some were camel-glazed muffins and some were lemon. The Carmel muffins cost $3 each while the lemons cost $2.5 . The number of carmel muffins and lemon muffins can be calculated as follows

total number of muffin = 20

Let

a = number of carmel - glazed muffins

b = number of lemon muffins

a + b = 20.............(i)

The total cost

3a + 2.50b = 54................(ii)

Combine the equations

a + b = 20.............(i)

3a + 2.50b = 54................(ii)

a = 20 - b

insert the value of a in equation (ii)

3(20 - b) + 2.50b = 54

60 - 3b + 2.50b = 54

60 - 54 = 0.5b

0.5b = 6

divide both sides by 0.5

b = 6/0.5

b = 12

Insert the value of b in equation (i)

a + b = 20.............(i)

a + 12 = 20

a = 20 - 12

a = 8

The number of Carmel muffins is 8 and the number of lemon muffins is 12.

2. Quan plans to spend less than $80 for buying groceries. He plans to spend $68.25 on food and spend the rest on juice. Each ju

Phoenix [80]

A) 68.25+3x<80
b) subtract 68.25 from both sides of the inequality
3x<11.75 divide both sides by 3
x<47/12
Since x must be an integer, the greatest number of cartons that he can purchase is 3. Hope this helps:)
