Answer:

a) yes b) no c) no

Step-by-step explanation:

In order to know this, remember something: to do the division between a number and a rational number like this and with zero to the left, the best way to solve them is converting these number to a natural number.

To do that, you only need to multiply the number by 10, 100, 1000, depending of how many decimals it have.

In case a) 0.05 has two decimals, therefore we multiply by 100:

0.05 * 100 = 5

However, when you do that, you have to do the same thing with the number in the dividend, in this case, 1.4:

1.4 * 100 = 140

So we can conclude that 1.4 you have to add a zero to do the division.

Case b) and c) do not apply, in both cases we multiply by 10 and we get this:

25.2 and 6,

26.1 and 3.

What’s the answer to this question? I’m confused as to how to do this.
choli [55]

Answer:

x = 20

Step-by-step explanation:

(3x + 50) = (6x - 10)

Subtract 6x on each side

3x + 50 - 6x = -10

Combine the x values together

-3x + 50 = -10

Subtract 50 on each side

-3x = -60

Divide each side by -3

x = 20

Step-by-step explanation:

Ted is making trail mix for a party. He mixes 1 1/2 cups of nuts, 1/4 cup of raisins, and 1/4 cup of pretzels.

So, 1/4 cup of pretzels to make 1 trail mix

       x cups of pretzels to make 15 trail mix

Using the ratio and proportional

∴ x = (1/4) * 15 = 3.75 = 3\frac{3}{4} cups.

<u>Ted will need </u>3\frac{3}{4}<u> cups of pretzels to make 15 cups of trail mix.</u>

The cost of eight stress balls and five T-shirts is $111.75. The cost of twelve stress balls and four T-shirts is $102.00. What
aksik [14]
Let's say stress ball cost x and t shirt cost y
8x+5y=111.75
12x+4y=102.00→3x+y=25.5→y=25.5-3x

8x+5(25.5-3x)= 111.75
8x+127.5-15x=111.75
-7x=-15.75
x=2.25

12x+4y=102
12(2.25)+4y=102
27+4y=102
4y=75
y=18.75

d is the correct answer
