Simplifying 6y + 1 = 21y + 13

Reorder the terms: 1 + 6y = 21y + 13
<span>Reorder the terms: 1 + 6y = 13 + 21y

</span><span>Solving 1 + 6y = 13 + 21y

</span><span>Solving for variable 'y'.

</span><span>Move all terms containing y to the left, all other terms to the right.

</span><span>Add '-21y' to each side of the equation. 1 + 6y + -21y = 13 + 21y + -21y

</span><span>Combine like terms: 6y + -21y = -15y 1 + -15y = 13 + 21y + -21y

</span><span>Combine like terms: 21y + -21y = 0 1 + -15y = 13 + 0 1 + -15y = 13

</span><span>Add '-1' to each side of the equation. 1 + -1 + -15y = 13 + -1

</span>Combine like terms: 1 + -1 = 0 0 + -15y = 13 + -1 -15y = 13 + -1
Combine like terms: 13 + -1 = 12 -15y = 12
Divide each side by '-15'. y = -0.8
<span>Simplifying y = -0.8</span>

Could someone please explain this problem to me?
disa [49]

Answer:

8/3

Step-by-step explanation:

Because all 4 angles are congruent, the sides are proportional.

the scale factor is 5/30 = 1/6.

meaning x = 16(1/6)=8/3.

I really need help with 15 and 16 please
Mandarinka [93]

Answer:

  15. 50 kg

  16a. 5 kg

  16b. 3.75 kg

Step-by-step explanation:

The formula relating force, mass, and acceleration can be solved for mass. This formula will apply to both problems. We'll use m for both "mass" and "meters". We presume you can avoid getting mixed up by understanding that meters is used in the context of acceleration: m/s².

  F = ma

  m = F/a . . . . . divide by a

__

15. m = (250 N)/(5 m/s²) = 50 kg

__

16a. m = (15 N)/(3 m/s²) = 5 kg

16b. m = (15 N)/(4 m/s²) = 3.75 kg

_____

<em>Comment on units</em>

Especially for physics problems, I like to keep the units with the numbers. It is helpful to remember that Newtons are equivalent to kg·m/s². So, dividing Newtons by acceleration in m/s² will give mass in kg. Since you're familiar with F=ma, it's not too hard to remember that the units of force (N) are the product of the units of mass (kg) and acceleration (m/s²).

A tray contains 16 chocolate chip cookies and 12 oatmeal raisin cookies. HOw many ways can a child select 3 cookies that include
pishuonlain [190]

Answer:

Number of ways chosen cookies = 8 ways

Step-by-step explanation:

Given;

Total number of chocolate chip cookies = 16

Total number of oatmeal raisin cookies = 12

Total number of cookies choose = 3

At least 1 chocolate cookie

Find:

Number of ways chosen cookies

Computation;

Number of total ways = 2³

Number of total ways = 8

If at least on cookie is chocolate cookie,

Number of ways chosen cookies = Number of total ways - 1

Number of ways chosen cookies = 9 - 1

Number of ways chosen cookies = 8 ways
