Answer:

193 = 7s + 8l ( Grad Party Equation)

92 = 8s + 2l (Father's Day Equation)

The small balloon bouquet uses 7 balloons and the large one uses 18 balloons

Step-by-step explanation:

First we need to separate something, I chose l...

92 = 8s + 2l
2l = 92 - 8s
l = 46 - 4s

...and we can replace this for l in the other equation!

193 = 7s + 8( 46 - 4s )
193 = 7s + 368 - 32s
-175 = -25s
7 = s

Now that we have found the number of balloons needed for a small bouquet we can place that in an equation to find out how many balloons it takes to make a large bouquet.

l = 46 - 4(7)
l = 46 - 28
l = 18

Now just to make sure we got that right. Just check them!

Grad Party Equation

193 = 7s + 8l
193 = 7(7) + 8(18)
193 = 49 + 144
193 = 193

We got one right and the other one...

Fathers Day Equation

92 = 8s + 2l
92 = 8(7) + 2(18)
92 = 56 + 36
92 = 92

We got both right yay!

Answer:

The small balloon bouquet uses 7 balloons and the large one uses

18 balloons.

Step-by-step explanation:

Let's say that small balloon bouquets are S and large balloon bouquets are L. For the graduation party the employee assembled 6 small bouquets and 6 large bouquets, the total number of balloon used is 150. To put the sentence into an equation will be:

6S + 6L= 150

S+L= 25 ----> 1st equation

For Father's Day, the employee uses 6 small bouquet and 1 large bouquet, the total number of balloons used is 60. The equation will be:

6S + 1L= 60

1L= 60- 6S ----> 2nd equation

We can solve the number of small balloon bouquet by substitute the 2nd equation into 1st. The calculation will be:

S+L = 25

S+ (60-6S)= 25

-5S= 25-60

-5S= -35

S= -35/-5

S=7

Then we can find L by substitute S value to 1st or 2nd equation.

S+L=25

7+L=25

L=18

Hope this helps ;)

Answer:

Question 1:

5 pints per hour

Question 2:

480 tons per day

Question 3:

12 miles per gallon of gasoline

Step-by-step explanation:

Question 1:

<h2>In the morning;</h2>

A farm worker packed 3 pints of grapes every 4 minutes.

1 minute = $\frac{1}{60}$ hours

Packing rate in pints per hour = 3 pints ÷ $\frac{4}{60}$ hours = 45 pints per hour

<h2>In the afternoon;</h2>

She packed 2 pints of grapes every 3 minutes.

Packing rate in pints per hour = 2 pints ÷ $\frac{3}{60}$ hours = 40 pints per hour.

The difference between her morning and afternoon packing rates (in pints per hour) = 45 pints per hour - 40 pints per hour = 5 pints per hour

Question 2:

A recycling plant processes an average of $\frac{1}{3}$ tons of glass each minute.

1 hour = 60 minutes

The number of tons of glass processed in 1 hour is:

$\frac{1}{3}$ × 60 = 20 tons of glass in 1 hour.

1 day = 24 hours

Number of tons of glass processed in a day = 20 tons × 24 = 480 tons

Question 3:

A vehicle uses 1 $\frac{1}{8}$ gallons of gasoline to travel 13 $\frac{1}{2}$ miles.

Per 1 gallon of gasoline the vehicle will travel:

1 × 13 $\frac{1}{2}$ ÷ 1 $\frac{1}{8}$ = 12 miles

Hope this helps!

Step-by-step explanation:

Create you equation:

x = the total amount the water changed

d = the amount of days

x = -4d

Insert the known information into the equation and solve:

x = -4d

x = -4(7)

x = -28
