Answer 1
Answer:

The total amount they will pay $156. Therefore, option D is the correct answer.

Given that, the bill at the restaurant=$119, tax=9% and tip=22%.

How to calculate the percentage of a number?

How to calculate the percentage of a number. Use the percentageformula: P% * X = Y · Convert the problem to an equation using the percentageformula: P% * X = Y.

Now, the total percentage they paid extra=9+22=31%.

So, 119+31% of 119=119+36.89

=155.89≈$156

Therefore, option D is the correct answer.

Answer 2
Answer:

119  * .09 = 10.71

119+10.71= 129.71

129.71 * .22 = 28.54

129.71+28.54= 158.25

ask your self do 3,4 and 5 have any common factors

if not factor out one of the numbers

OBJECTIVE IS TO GET ALL NUMBERS TO 1 and multiply all factors once they do

so

3 goes into 3 once

3 goes into 4 0 times

and 3 goes into 5 0 times

next take 4 and do the same

take 5 and do the same as well

the factors u should be left with are 3,4,5

now multiply these

3*4*5=60

lcm=60

How to solve question 22?

Answers

Answer:

Josh has 29 coins.

Step-by-step explanation:

Let Terry have x coins then Josh has x + 12 coins.

Together they have x + x + 12 coins so we can form the equation:

x + x + 12 = 46

2x + 12 = 46

2x = 46 - 12 = 34

x = 17, so Terry has 17 coins and Josh has 17 + 12 = 29 coins.
Answer - C - 29
That is , Josh has 29 coins.

DeShawn uses 3/4 of a box of rice to cook dinner. The portion he uses weighs 12 ounces. Write and solve and equation to find the weight of the full box kf rice.

Answers

Answer:

16\ ounces

Step-by-step explanation:

we know that

3/4 of a box of rice weighs 12 ounces

so by proportion

Find the weight of the full box of rice

(12)/((3/4))(ounces)/(box) =(x)/(1)(ounces)/(box)\n \nx=12/(3/4)\n \nx=16\ ounces
3/4 box = 12 oz

we first need to find 1/4 of a box. to do that divide both sides by 3

1/4 box = 4 oz

for a full box which is 4/4 multiply both sides by 4

1/4 x (4)  = 4 x (4) oz

4/4 ( or one whole) = 16 oz

A number decreased by 5 is less than 32

Answers

I believe they want you to write an equation...

"a number" = x
"decreased by 5" = -5
"is less than 32" = <32

x - 5 < 32

That is the equation.

If you solve it...

x < 32+ 5
x < 37

x can be any number less than 37 to keep the equation true.
No. A number DECREASED by 5 IS 32. That means you ADD 5. So the correct answer is 37.
