She shouldn't tip at all since that's a ridiculous concept

Step-by-step explanation:

common sense

SORRY MADE A MISTAKE WITH THE CALCULATOR I KNEW I MESSED SOMETHING UP

The cost of the meal was $22 so that's the price plus tax and tax is 10% of the price so

cost = price + 0.1*price

cost = 1.1 * price

price = cost / 1.1

price = 22 / 1.1 = 20

now we need 20% of that so that's

20 * 0.2 = 4

If she's simple-minded enough to tip that would amount to $4

Answer:

7y + 10

Step-by-step explanation:

Group the like terms

3y + 4y +7+3

7y+ 10

The simplified expression of 3y + 7 + 4y + 3 is 7y + 10.

A mathematical expression is made up of a statement, at least one arithmetic operation, and at least two integers or variables.

An expression or mathematical expression is a finite combination of well-formed symbols that adhere to context-dependent criteria.

Given:

The expressions, 3y + 7 + 4y + 3,

Simplify the above expression as shown below,

3y + 4y + 3 + 7    (Rearrange the variable and constant terms)

7y + 10   (Add the variable and constant)

Thus, the expression is 7y + 10.

Answer:

x = 58º

Step-by-step explanation:

the sum of angles on the same side equals 180º so...

122º+x = 180º        subtract 122º from both sides

x = 58º

Step-by-step explanation:

The hypotenuse of a triangle must be longer than the other sides.

Answer:

Step-by-step explanation:

ccording to the question

3x + 7x = 350

10x =350

X = 35

Therfore

3x = 35 *3 = 105

7x = 35 *7 = 245

Follow me and mark me as a brainliest

Step-by-step explanation:

let ratio be 3xand7x

now,

3x+7x=350

10x=350

x=350/10

x=35

then,

3x=3×35=105

7x=7×35=245

Answer:

5 cookies left

Step-by-step explanation:

First you make the fraction equal by multiplying them

2/3 multiply both numerator and denominator by 4

= 8/12

Now you divide 60 by 12 to find the amount to make the denominator 60

60 divided by 12 = 5

8/12 multiply both numerator and denominator by 5

= 40/60

So now we know the amounts

She gave 40 away so she has 20 left (60 - 40 = 20)

Now make 3/4 numerator and denominator by equal to 20

Multiply them by 5

15/20

She had 5 cookies left

Answer:

n = 6

Step-by-step explanation:

17n + 4n - 4 =122

combine like terms  17n & 4n

21n - 4 = 122

21n - 4 + 4 = 122 + 4

21n = 126

21n / 21 = 126 / 21

n = 6

Step-by-step explanation:

Answer:

6*18=108

36*15=540 so 216+540 addition first then subtracting so 215+540=755-180=575

Answer:

y ≈ 5.2

Step-by-step explanation:

∠ F = 180° - (42 + 48)° ← sum of angles in a triangle

∠ F = 180° - 90° = 90°

Thus Δ DEF is right at F

Using the sine ratio in the right triangle

sin48° = [tex]\frac{opposite}{hypotenuse}[/tex] = [tex]\frac{DF}{DE}[/tex] = [tex]\frac{y}{7}[/tex] ( multiply both sides by 7 )

7 × sin48° = y , then

y ≈ 5.2 ( to the nearest tenth )

Answer:

A) Ms. Swift can conclude that hey are similar, because line E,C,A is collinear, and they both are right triangles.

B) 158.3ft

Step-by-step explanation:

A) Having a collinear line makes the triangles similar, and because of their collinear line they are both right triangles.

B) The question tells you DE is 103 ft. You take 76ft and Square it giving you 5776ft You then take 103 and square it giving you 10609ft adding them together gives you 16385ft you take the square root of it and it gives you the hypotenuse of triangle CDE. To get the hypotenuse of triangle ABC you take The expression (AB/DE)=(BC/CD)=(AC/EC) step one (AB/DE)=(94ft/76ft)=AC/DE) step two (103ft/127ft)=(94ft/76ft)=(AC/DE) third step (103ft/127ft)=(94ft/76ft)=(128ft/158.3)

I truly hope this helps! :)
