If you could buy ice cream and watermelon together for $2.55. how much would each one cost individually

frutty [35]

Answer:

$1.27 and the other is $1.28

Step-by-step explanation:

you would take $2.55 and divide by 2 because there are 2 items; ice cream and watermelon.

$2.55 / 2 is $1.27 a piece but that will leave 1 penny left so it would be added to either the watermelon or the ice cream. So one would be $1.27 and the other would be $1.28

Answer:

3 gallons

Step-by-step explanation:

Let

x ----> the amount of pure acid (100% solution) in gallons

Remember that

$100\%=100/100=1$

$20\%=20/100=0.20$

$60\%=60/100=0.60$

we know that

$(1)(x)+(0.20)(3)=(0.60)(x+3)$

solve for x

$x+0.60=0.60x+1.80$

$x-0.60x=1.80-0.60\\0.40x=1.20\\x=3\ gal$

therefore

3 gallons of pure acid should be mixed with 3 gallons of a 20% acid solution in order to get a 60% acid solution

A teacher spends $354 on costumes and microphones for six cast members in a play. Each cast member receives a costume that costs

KATRIN_1 [288]

The teacher spend some amount on buying costumes and microphones for 6 cast members.

GiveN:

Cost of each costume = $38
Cost of each microphone = $c
Total money spent = $354

Let's frame the equation. Total money is the total amount spent for 6 cast members.

Money spent on costumes = $38 × 6

Money spent on microphone = $c × 6

Equation:

$6 \times 38 + 6 \times c = 354$

Taking 6 as common,

$6(38 + c) = 354$

Dividing 6 from both sides,

$\dfrac{6(38 + c)}{6} = \dfrac{354}{6}$

$38 + c = 59$

Solving further,

$38 + c - 38 = 59 - 38$

$c = 21$

So, the cost of each microphone = $21

The teacher spent this much on each microphone.
