There is no x to solve, so I will solve for y.

y=-1.8

What I did was simplify and get the term one side.

Answer:

y = -1.8

Step-by-step explanation:

0.6+(0.5y-1)=y+0.5

the parenthesis can be remove because there is no multiplication

0.6 + 0.5y - 1 = y + 0.5

now combine numbers

0.6 - 1 + 0.5y = y + 0.5

-0.4 + 0.5y = y + 0.5

subtract 0.5 from both sides

-0.4 - 0.5 + 0.5y = y

-0.9 + 0.5y = y

now subtract 0.5y from both sides

-0.9 = 1y - 0.5y

-0.9 = 0.5y

now divide both sides by 0.5 and switch

y = -1.8

Which of the following values cannot be probabilities? 3/5, 2, 0, 1, −0.45, 1.44, 0.05, 5/3 Select all the values that c

Alik [6]

Given:

The numbers are $\dfrac{3}{5},2,0,1,-0.45, 1.44$ .

To find:

All the values that cannot be probabilities.

Solution:

We know that,

$\text{Probability}=\dfrac{\text{Favorable outcomes}}{\text{Total outcomes}}$

The minimum value of favorable outcomes is 0 and the maximum value is equal to the total outcomes. So, the value of probability lies between 0 and 1, inclusive. It other words, the probability lies in the interval [0,1].

$0\leq \text{Probability}\leq 1$

From the given values only $\dfrac{3}{5}, 0, 1$ lie in the interval [0,1]. So, these values can be probabilities.

The values $2,-0.45, 1.44$ does not lie in the interval [0,1]. So, these values cannot be probabilities.

Therefore, the correct values are $2,-0.45, 1.44$ .

Help asap! Please! A 40 cm tomato plant cast a 25cm shadow. How tall is the corn stalk if it's shadow is 280cm long?

Angelina_Jolie [31]

Answer:

448

Step-by-step explanation:

This is a proportion question. Keep the heights on one side of the proportion and the shadow length on the other.

height ratio shadow ratio

40 cm / x = 25 / 280 Cross multiply

25x = 40 * 280 Combine

25x = 11200 Divide by 25

x = 11200/25

x = 448 cm

The height of the corn plant is 448 cm

Help? : )) thank yall

elena-14-01-66 [18.8K]

Answer:

Third option: $-10x^7y^2$

Step-by-step explanation:

$12x^4\left(-\frac{5}{6}x^3y^2\right)$

Remove brackets:

$12x^4\times-\frac{5}{6}x^3y^2$

Multiply the $x^2$ :

$12\times-\frac{5}{6}x^{4+3}\times y^2$

$12\times - \frac{5}{6}x^7y^2$

Multiply:

$-\frac{5\times \:12x^7y^2}{6}$

$-\frac{60x^7y^2}{6}$

Divide:

$-10x^7y^2$
