estimate a 20% tip for $31.15
$4.65

$3.10

$6.20

$12.40

Answers

Answer: 6.20$

Step-by-step explanation:

$6.23

I am going to explain it two different ways.

31.15 x 0.20 = 6.23
31.15 +6.23 tip = 37.38 for you total bill including tip

An easier way my mom taught me for tipping in restaurants is you look at the bill $31.15 in this case move the decimal to the left one place and that give you 10%..double it and you have your 20% tip.
3.11 + 3.11 = 6.22
This way you don’t have to take a calculator out in front of anyone to calculate the tip.

Pls help me with this, thanks

Hi! i'm showing this to my sister and she wants to know, At a yard sale, Jennifer sold 2 tricycles for $22.50 each, 3 old video games for $2.75 each, a video for $5.00, and a dictionary for 75 cents. How much money did she make?

Answers

45+8.25+5+0.75 is what you need to add

Jennifer made $59.

$22.50 times 2 is $45 and $2.75 times 3 is $8.25, the sum of these numbers is $53.25.

$5 plus $0.75 is $5.75, and the sum of $5.75 plus $53.25 is exactly 59 dollars.

If this is incorrect, please, don't refrain to tell me.

Maria has two options for buying a new computer. She can pay $750 right now, or she can pay $24.99 each month for 3 years. How much more will Maria pay if she makes payments for 3 years?

Answers

Answer:

$149.64

Step-by-step explanation:

Recall that there are 12 months in a year.  Thus, 3 years would be 36 months.

$24.99 times 36 months comes to $899.64.  To determine how much more Maria will pay by making monthly payments is $899.64 less $750, or $149.64.

what is the solution to the system? with a graph
y=-x+2
y=3x-1​

Answers

Answer:

x = 3/4

y = 5/4

Step-by-step explanation:

Step:

Substitute−x+2 for y in y=3x−1:

y=3x−1

−x+2=3x−1

−x+2+−3x=3x−1+−3x(Add -3x to both sides)

−4x+2=−1

−4x+2+−2=−1+−2 (Add -2 to both sides)

-4x = -3

x=3/4

Step: Substitute x into the original equation

y=-3/4 + 2

y=5/4

Which measurements is equivalent to 4,000 centimeters? (100 centimeters = 1 meter)

Answers

Answer:

400 meters = 4000 centimeters

Step-by-step explanation:

Sorry if this didn't help

The solution is , 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.

What is equation?

An equation is a mathematical statement that shows that two expressions are equal. It consists of two sides, left-hand side (LHS) and right-hand side (RHS), connected by an equal sign (=). The LHS and RHS can contain numbers, variables, operators, and functions, and the equal sign indicates that the value of the expression on the LHS is equal to the value of the expression on the RHS.

Here,

we know,

100 centimeters = 1 meter

Since there are 100 centimeters in one meter, we can convert meters to centimeters by multiplying the length in meters by 100.

So, to convert 40 meters to centimeters, we can multiply 40 by 100:

40 meters = 40 x 100

= 4,000 centimeters

Therefore, 4,000 centimeters are equivalent to 40 meters. Hence, the answer is A) 4,000 cm.
