Mathematics Middle School

Mac and his brother Ted collect coins. Mac's collection contains 8 more than twice as many as Ted's. If the total number of coins in the two collections is 74, how many coins are in each collection? If x represents the number of coins in Ted's collection, then which expression represents the number of coins in Mac's collection?
x + 2(8)
2( x + 8)
2 x + 8

Answers

Answer 1

the third option makes the most sense because 2 times what ted would be 2x plus 8 more. 2x+8

Answer 2

2x + 8 that's the right answer just letting you know yeah your welcome have a good one homie ;)

3x + 2 = -55 i need all the steps

Answers

Answer:

-19

Step-by-step explanation:

3x+2 = -55

-2 -2

3x = -55-2

3x = -55+-2

3x = -57

/3 /3

x=-19

Answer:

-19

Step-by-step explanation:

[tex]3x + 2 = -55[/tex]

[tex]3x = -55[/tex]

[tex]-2[/tex] (2 is negative because it was moved to the other side of the equation)

[tex]3x/3 = -57/3[/tex] (Divide both sides of the equation by 3 to isolate x.)

[tex]x = -19[/tex]

4/9 kilogram of baking soda costs $2. How much does 1 kilogram of baking soda cost?

please drop an explanation, and equation thanks!

Answers

Ok so we want to cross multiply.
To do this you know 4/9=2$ so now you want to know 1=x$
When you do this you get $5

Answer:

1 kg of baking soda costs $4.50.

Step-by-step explanation:

Write and solve an equation of ratios, as follows:

4/9 kg $2

------------- = --------------

1 kg x

Multiplying both numerators by 9, we get:

4 kg $18

------------ = ---------

1 kg x

Cross-multiplying, we get 4x kg = $18-kg. Solving for x, we get:

$18-kg

x = -------------- = $4.50

4kg

1 kg of baking soda costs $4.50.
