Answer this question but I need you to show work

Answers

just add the 2 numbers together,

 the less expensive player cost $238 and it is $98 less than the more expensive one

 more expensive one cost 238 + 98 = $336

x = less expensive one. y = most expensive one

x = y - 98
x = 238

238 = y - 98
238 + 98 = y
336 = y <== the expensive one

Jeannine runs for 45 minutes every day for exercise. It takes her 8 minutes to run a mile, and she spends 5 minutes stretching halfway through the run. If x represents the number of miles she runs, then 8x + 5 ≤ 45 represents the time she runs each day. What is the fewest number of miles Jeannine must run to complete her daily exercise?

Answers

8x5<45 -5 -5 ------ 8x<40 ------- 8 8 x<5 So the fewest of miles she could run is 1, 2, 3, or 4 miles

Write each ratio as a fraction in simplest form. Then explain its meaning. 4 flutes and two drums

Answers

The ratio would be 4:2. In simplest form, it would be 2:1. The meaning is that since there are 4 flutes, the first ratio number would be 4. Same with the 2 drums. How you would simplify it is that you have to minus it down. Since 2 can go into 4, the logical answer would have to be 2:1

The ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.

What is a Ratio?

A ratio expresses the number of times one number contains another. For example, if a dish of the fruit contains eight oranges and six lemons, the orange-to-lemon ratio is eight to six.

A ratio shows us the number of times a number contains another number. Given the following details:

Number of drums = 2

Number of flutes = 4

The ratio for the number of drums to the number of flutes in its simplest form can be written as,

Number of drums / Number of flutes = 2 / 4

Dividing both the numerator and the denominator of the fraction by 2, we will get,

Number of drums / Number of flutes = 1/2

Hence, the ratio as a fraction in its simplest form for the Number of drums and flutes is 1:2.

A cleaner recommends mixing 1½ cup of cleaner for every 12 cups of water. What is the ratio of cleaner to water in simplest form?


1/8


2/3


1/2


7/8

Answers

1/8, because 3/2 divided by 12 is 1/8

we know that

To find the ratio of cleaner to water

Divide the total cups of cleaner by the total cups of water

In this problem we have

total cups of cleaner------> [tex]1\frac{1}{2}[/tex]

convert to an improper fraction

[tex]1\frac{1}{2}=\frac{1*2+1}{2}= \frac{3}{2}[/tex]

total cups of water------> [tex]12[/tex]

Find the ratio

[tex]\frac{(3/2)}{12}= \frac{3}{24}= \frac{1}{8}[/tex]

therefore

the answer is

[tex]\frac{1}{8}[/tex]

Divide. −24/7 please help

Answers

-24/7 = -3.42857

positive divided by positive = positive

negative divided by negative = positive

positive divided by negative = negative

negative divided by positive = negative

hope this helps

To divide -24 by 7, divide 24 by 7 to get 3.4286 and then apply the sign, resulting in -3.4286 as the answer.

The student's question involves the arithmetic operation known as division. To divide
-24 by 7, you would perform the division as you would with positive numbers, then apply the sign of the numbers. Since one number is negative and the other is positive, the result will be negative. Performing the division: 24 divided by 7 equals approximately 3.4286. Since
24 is negative, the result is -3.4286. When dividing by a single digit, you don't necessarily need to apply long division; instead, you can estimate how many times 7 fits into 24.
Remember that division by powers of 10 involves moving the decimal point. However, that's not applicable here since 7 is not a power of 10.

Jerri needs 3/4 cup of oil and 1 cup of vinegar to make salad dressings. If he only has 2/3 cup of vinegar, how much oil should he use?

Answers

(3/4) / 1 = x / (2/3).....3/4 oil to 1 cup vinegar = x oil to 2/3 cups of vinegar
cross multiply because this is a proportion
(1)(x) = (3/4)(2/3)
x = 6/12 reduces to 1/2 cup of oil <===
if he has 2/3 cup of vinegar he must put 0.4 cup of oil

a recipe calls for 1 1/2 cups of flour, 3/4 cups of white sugar, and 1/3 cup of brown sugar the recipe makes 6 servings.

(a) how many total cups of flour are there per serving? show your work

(b) how many total cups of sugar (white and brown) are there per serving?show your work

(c) supposed you modify the recipe so that it makes 9 servings. How much more flour do you need for the modified recipe than you need for the original recipe?Show your work

Answers

Answer:

(a) 0.25 cups of flour

(b) 0.18 cups of sugar

(c) 0.5 cups of flour

Step-by-step explanation:

The recipe requires 3 amounts of ingredients to make 6 servings. The following is needed:

1. 1 1/2 cups of flour

2. 3/4 cups of white sugar

3. 1/3 cups of brown suger

a) The total cups of flour per serving can be determined by dividing the flour needed for 6 servings by 6:

[tex]=1.5/6=0.25[/tex]

0.25 cups of flour is needed per serving

b) The total cups of brown and white sugar can be determined by divided both quantites by 6 servings.

For brown sugar = 0.75/6 = 0.125 cups of brown sugar

For white sugar = 0.333/6= 0.0555≈0.055 cups of white sugar

Total amount of sugar = brown sugar + white sugar = 0.125+0.055=0.18 cups of sugar

c) If we can make 9 servings we can determine the the percentage of more servings and the amount of flour for the modified recipe.

The percentage change of recipes = ((9-6)/9)*100=33.33%

Therefore the new amount of flour needed is:

[tex]1.5*0.3333+1.5=2[/tex]

Therefore we need 2-1.5=0.5 cups more flour than the original recipe

Answers

Hey!

So, If you want to figure out how much marbles Marsha gets, you first divide 144 by 2. And that equals 72. So Marsha gets 72. THEN, Halve goes to Sam so Sam gets halve of 72. And halve of 72 is 36. 

SO MARSHA GETS 72 MARBLES JEREMY GETS 36 AND SAM GETS
36.


Yeah Marsha gets 72 marbles and Jeremy gets 36 and Sam gets 36
