Answer:

58 number of dimes.

A. $5.8

B. 131.602 grams.

Step-by-step explanation:

A U.S. dime has a thickness of 1\frac{7}{20} = 1.35 mm.

Now, Gary has a stack of dimes that is 78\frac{3}{10} = 78.3 mm in height.

Therefore, Gary has \frac{78.3}{1.35} = 58 dimes in total.

A. Now, each dime is equivalent to $0.1.

Therefore, the total value of the dimes that Gary has is $(0.1 × 58) = $5.8.

B. If each dime weighs 2.269 grams, then the mass of the entire stack of dimes will be (2.269 × 58) = 131.602 grams. (Answer)

6x=2x+44 solve for x
agasfer [191]

Answer:

\boxed{ \bold{ \huge{ \boxed{ \sf{x = 11}}}}}

Step-by-step explanation:

\sf{6x = 2x + 44}

Move 2x to left hand side and change it's sign

⇒\sf{6x - 2x = 44}

Collect like terms

⇒\sf{4x = 44}

Divide both sides of the equation by 4

⇒\sf{ \frac{4x}{4}  =  \frac{44}{4} }

Calculate

⇒\sf{x = 11}

Hope I helped!

Best regards!!
