-10 times 1 equals w+5.3

Inessa [10]

-10(1) = w + 5.3

-10 = w + 5.3

-10 (-5.3) = w + 5.3 (-5.3)

w = -15.3

hope this helps

Answer:

270 tomatoes

Step-by-step explanation:

Lets organize the Info

Carrots to Potatoes is 1:2

Potatoes to Tomatoes is 1:3

There are 45 Carrots

So lets input it in the ratio Carrots : Potatoes

45 : 2(45)

45 : 90

There are 90 Potatoes in the garden

Lets input that info to the ratio Potatoes : Tomatoes

90: 3(90)

90 : 270

Summarize:

There are :

45 carrots

90 potatoes

270 tomatoes

-1 2/3 / (-2 1/5)<br> solve this for me please &&' thank you

dangina [55]

Start by putting into improper fractions.
- 1 2/3 = - 5/3
- 2 1/5 = - 11/5

Now stack the fractions like this.

$\frac{ \frac{-5}{3} }{ \frac{-11}{5} }$

Here's the key part (or one of them). Cancel the minus signs. Since there are 2 of them they become a plus.

$\frac{ \frac{5}{3} } { \frac{11}{5} }$

Now invert the 11/5. That means turn it upside down. Put the 5 in the numerator and 11 in the denominator. Multiply by it by the top fraction.

$\frac{5}{3} * \frac{5}{11}$

When you do this, you just multiply top by top and bottom by bottom

Use inductive reasoning to predict the most probable next number in each list.

PolarNik [594]

Answer:

93

Step-by-step explanation:

First differences increase by 4 each time. The given numbers are a quadratic sequence that can be described by 2n² -2n +9. The 7th term would be 93.

_____

First differences are ...

13-9 = 4, 21-13 = 8, 33-21 = 12, 49-33 = 16, 69-49 = 20

Second differences are ...

8-4 = 4, 12-8 = 4, 16-12 = 4, 20-16 = 4

When second differences are constant, the sequence can be represented by a second-degree polynomial function. The leading coefficient is half the value of the second differences.
