Let H be hamburger and C be chesseburger.

H+C=559
H+59=C

H+(H+59)=559
2H+59+559

2H=559-59
2H=500

H=500/2
H=250

250 hamburgers were sold on Saturday.

A rectangular prism has a volume of 750 cubic millimeters. Its length is 15
umka2103 [35]

Answer: 5 milimeters.

Step-by-step explanation:

The formula for calculate the volume of a rectangular prism is:

V=lwh

Where "V"  is the volume, "l" is the lenght, "w" is the width and "h" is the height.

You know that the volume, the lenght, and the width of this rectangular prism are:

V=750mm^3\\l=15mm\\w=10mm

Substitutute these values into the formula and solve for the the height "h":

750mm^3=(15mm)(10mm)h\\\\h=\frac{750mm}{(15mm)(10mm)}\\\\h=5mm

Find the measure of an angle whose measure is 20° less than the measure of its supplement.
Tasya [4]
Supplementary = angles add up to 180
Measure = 20 less

Labelled as x + (x - 20) = 180

Solve.

x + (x - 20) = 180
             2x = 200
             /2      /2
               x = 100

Angle 1:             Angle 2:
x - 20                  x
100 - 20             100
80

Therefore the angle is 80 degrees.

Proof: 80 + 100 = 180 (supplementary)
100 - 80 = 20 (80 is less than supplement (100)

Hope I helped :))))

-10n+50=-7(4n+8)-2 no solution many solution
ziro4ka [17]

Answer:

n=-6

Step-by-step explanation:

distribute -7 into (4n+8)

-10n+50=-28n-56-2

combine like terms

-10n+50=-28n-58

add -28n on both sides

-10n+28n+50=-58

combine like terms again

18n+50=-58

subtract 50 on both sides

18n=-108

divide both sides by 18

\frac{18x}{18} =\frac{-108}{18}

x=-6

hope this helps

Franco made a dozen muffins for his party. Upon taking them out of the oven,
Naddik [55]

Answer:

Option B.

Step-by-step explanation:

This question is incomplete; find the complete question with the attachment.

Franco made number of muffins = a dozen

A dozen muffins = 12 muffins

Number of muffins were burned = 2

Remaining muffins = 12 - 2 = 10

Franco served 7 of the remaining non-burned muffins,

Fraction of muffins served = \frac{7}{10}

Remaining muffins = 3

Fraction of remaining muffins = \frac{3}{10}

Fraction of remaining non-burned muffins we can get from,

\frac{10}{10}-\frac{7}{10}=\frac{3}{10}

Option B is the correct equation.
