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 ;)

Sam ran 63,756 feet in 70 minutes. What is sam’s rate in mile per hour

Stella [2.4K]

Answer:

10 miles per hour

Step-by-step explanation:

there are 60 minutes in an hour once you covert you have that it took 1.17 hours then there are 5280 feet in a mile so you convert and get 12.075 miles

you divide

12.075/1.17 = 10.3205128

then you simplify to the nearest whole number and get 10

If the discriminant is negative then the quadratic has

zepelin [54]

Answer:

No real solutions (or has two complex roots)

Step-by-step explanation:

The discriminant, b² - 4ac, is the expression (radicand ) of the quadratic equation:

$x = \frac{-b +/- \sqrt{b^{2}-4ac} }{2a}$ .

The value of the discriminant determines the nature and the number of solutions given by the quadratic equation.

A discriminant with a negative value (or b² - 4ac < 0 ) means that the quadratic equation has no real solutions or two complex solutions. Quadratic equations with a negative discriminant also have no x-intercepts; thus, its graph will not cross the x-axis.

Need help on #6 step by step I'm so confused how this works I always get stuck

inna [77]

To find the variable x, set the two outside equations equal to each other because all sides are equal
x+13=3x+3
13=2x+3
10=2x
x=5

then to find h, you set the equation equal to 90 because that's how many degrees it is
2h-45=90
2h=135
h=67.5
