Answer:

6/35

Step-by-step explanation:

so he ate 2/5 first day, and the 3/7 the other day, so we need to add the 3/7 to 2/5.

they had to have the same number as their denominator.

so we gonna multiply (5) (3) and (5) (7) and also (7) (2) and (7) (5)

then we have 14/35 and 15/35 so we can add them together to find out 29/35

then we minus it from 35/35 to find out how much is left

35/35 - 29/35 is 6/35 , which is our answer

Marty went shopping for school supplies. He bought a package of pens for $2.25, a package of paper for $3.25, a notebook for $5.
Marat540 [252]

Answer:

$3.50

Step-by-step explanation:

to find the range you take the highest number and the lowest number and subtract them

so with that, let us do just that-

$5.75, $3.75, $3.25, $2.25

$5.75-$2.25

=$3.5

and since we're dealing with money we must add a '0' to the end of the decimal- $3.50

good luck :)

i hope this helps

brainliest would be highly appreciated

have a nice day!

Anastasy [175]

Answer:

Total amount spent =\$73.5

If they decide to split the bill, amount paid by each of the person  =\$15.25

Step-by-step explanation:

Cost of each movie ticket = $11

Cost of 5 tickets = 5(11)= 55

Cost of each packet of popcorns = $3.75

Cost of two packets of popcorns = $2(3.75) = $7.5

Cost of each soda = $2.75

Cost of five sodas = $5(2.75) = $13.75

Total number of persons (Rachel and four friends) = 5

Total amount spent =11(5)+2(3.75)+5(2.75)=55+7.5+13.75=\$76.25

If they decide to split the bill, amount paid by each of the person = \frac{76.25}{5}=\$15.25

4. Which of the following is not a prime number? A. 19 B. 11 C. 5 D. 24
Anvisha [2.4K]

Answer:

D. 24

Step-by-step explanation:

A prime number is a number that only has 2 factors, which is 1 and itself. In other words, a prime number is only divisible by 1 and itself.

19 is a prime number, because it is only divisible by 1 and itself.

11 is also a prime number because it is only divisible by 1 and itself.

5 is also a prime number because it is only divisible by 1 and itself.

24 is not a prime number because it is divisible by 1 and itself, but it is also divisible by 2, 3, 4, 6, 8, and 12.

The answer is D.

How do i solve 1/4 (x+3)-4x<3 (1+x) ... its suppose to be a greater than or equal to sign
sdas [7]
First, multiply 1/4 by x+3 ⇒(1/4x+3/4). Next, multiply 3 by 1+x ⇒(3+3x). The equation should now look like this: 1/4x+3/4-4x≤3+3x. The next thing you have to do is get all of the x's on one side of the symbol. Subtract 1/4x from both sides, and the equation then looks like this: 3/4-4x≤3+2 3/4x. Add the -4x to both sides, and the equation should look like this: 3/4≤3+6 3/4x. Next, you have to move the 3 to the left side. To do that, subtract it from both sides. The equation then look like this: -2 1/4≤6 3/4x. Then, to get the x alone, you need to divide the coefficient (6 3/4) by -2 1/4, which equals -1/3 or -0.3 repeating. So, -1/3≤x

divide 41000 into two parts such that their amounts at 50% compound interest compounded annually in 2 and 3 years are equal​
Gnesinka [82]

Answer:24600 , 16400

Step-by-step explanation:

Let the first part be x

So, second part will be 41000 - x

For amount x

SI = prt / 100

SI = x * 0.50 * 2

SI = 1x

For amount 41000 - x

SI = (41000-x) * 0.50 * 3

SI = 61500 - 1.5x

1x = 61500 - 1.5x

1.5x + x = 61500

2.5x = 61500

x = 61500 / 2.50 = 24600 for 2 years

2nd part = 41000 - 24600 = 16400 for three years
