Answer with step-by-step explanation:

First of all, we need to calculate how many times the 3 lamps flash in a minute. We can do this by finding their LCM (least common multiple), which is 360. 360 is equivalent to 6 minutes, so that is going to be our test time. Lamp a flashes every 20 seconds, so 360/20 = 18 flashes. Then, 360/45 = 8 flashes. Finally, 360/120 = 3 flashes. 18 + 8 + 3 = 29 flashes per 6 minutes. If so, we multiply 29 by 10, because 60 minutes per hour ÷ 6 minutes = 10. So 29 × 10 = 290 flashes per hour

Answer:

[tex]\boxed {x = \frac{16}{3}}[/tex]

Step-by-step explanation:

Solve for the value of [tex]x[/tex]:

[tex]6 = x + \frac{2}{3}[/tex]

-Switch sides:

[tex]6 = x + \frac{2}{3}[/tex]

[tex]x + \frac{2}{3} = 6[/tex]

-Subtract [tex]\frac{2}{3}[/tex] to both sides and convert 6 to a fraction:

[tex]x + \frac{2}{3} - \frac{2}{3}= 6 - \frac{2}{3}[/tex]

[tex]x = \frac{18}{3} - \frac{2}{3}[/tex]

-Since both fractions have the same denominator, then you subtract the numerators:

[tex]x = \frac{18 - 2}{3}[/tex]

[tex]\boxed {x = \frac{16}{3}}[/tex]

Therefore, the value of [tex]x[/tex] is [tex]\frac{16}{3}[/tex].

Answer:

(Some textbooks describe a proportional relationship by saying that " y varies proportionally with x " or that " y is directly proportional to x .") This means that as x increases, y increases and as x decreases, y decreases-and that the ratio between them always stays the same.

Answer:

21

Step-by-step explanation:

1. (-4)2= 16

2.15/(-3)= 5

3. 16+5=21

Answer:

11

Step-by-step explanation:

First do -4^2

Then divide -15 and -3

Then 16-5

11

Step-by-step explanation:

2(x+6)=3(x+1)

2x+12=3x+3

collect the like terms

2x + 3x = 3+12

x=15/5=3

or

2x-3x = 3-12

= -9

Answer:

x = 5

Step-by-step explanation:

2x-1+9x+3=57

2x+9x=57+1-3

11x=55

x= 55/11

x= 5

Answer:

x = 5

Step-by-step explanation:

Simplifying 2x + -1 + 9x + 3 = 57

Reorder the terms: -1 + 3 + 2x + 9x = 57

Combine like terms: -1 + 3 = 2 2 + 2x + 9x = 57

Combine like terms: 2x + 9x = 11x 2 + 11x = 57

Solving 2 + 11x = 57

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-2' to each side of the equation. 2 + -2 + 11x = 57 + -2

Combine like terms: 2 + -2 = 0 0 + 11x = 57 + -2 11x = 57 + -2

Combine like terms: 57 + -2 = 55 11x = 55

Divide each side by '11'. x = 5

Simplifying x = 5

Answer:

y = 84

Step-by-step explanation:

[tex]\frac{8}{12} = \frac{56}{y}[/tex]

Cross multiply.

8y = 672

Step-by-step explanation:

B. False

they cannot be written as 10xy but only in 5x+5y

x and y will only become together if they are multiplied

as you can see there's a plus sign

you can add them if it is in 5x+5x (or) 5y+5y but never as in 5x+5y

Answer:

20/10 equals 2 rows. This is division

Step-by-step explanation:

Since you have 20 cupcakes and you put 10 in each row, you have to divide 20/10=2. This is your calculation.

Answer:

-2 =a

Step-by-step explanation:

6-4(a+2)=8+a

Distribute

6 - 4a - 8 = 8+a

Combine like terms

-2 -4a = 8+a

Add 4a to each side

-2-4a+4a=8+a+4a

-2 = 8+5a

Subtract 8 from each side

-2-8 = 8+5a -8

-10 = 5a

Divide each side by 5

-10/5 = 5a/5

-2 =a

Answer:

C) 6^6

Step-by-step explanation:

When we divide same base numbers with different exponents, the answer will be the base raised to the power of the difference of those exponents:

The rule is: x^a/x^b=x^(a-b)

In this case: 6^9/6^3=6^(9-3)=6^6=46656

Therefore, C is the correct answer
