Answer:
75cm²
Step-by-step explanation:
area of parallelogram= base*height
area=15*5=75cm²
Answer:
Step-by-step explanation:
Mass m=25 g
Volume V=1.29 cm³
density D=M/V
=25/1.29
≈19.38
≈19 g/cm³
Answer:
yes
they are equivalent because lets say the X = 3 then you would have to answer
3 + 3 + 1 + 3 + 2 + 3 + 1 + 3
and that would = 19
and then on the other equation
5 x 3 + 4 = 19
So the both equal the same.

Step-by-step explanation:
<u>to show how many tickets were sold:</u>
x = upper floor tickets
y = main floor tickets
x + y = 2000
<u>to show total amount of revenue:</u>
25x + 40y = 62,000
<u>Finding answer using both equations:</u>
x + y = 2000
multiply each side by 25
25x + 25y = 2000 × 25
25x + 25y = 50,000
25x + 40y = 62,000
-
25x + 25y = 50,000
-----------------------------------
15y = 12,000
^ this is column subtraction
<em>^ this column subtraction is done to isolate y so we can work with one value rather than 2</em>
15y = 12,000
divide each side by 15
12,000 ÷ 15 = 800
y = 800
x + y = 2000
x + 800 = 2000
x = 1200
Therefore 1200 upper-level tickets were sold
800 main floor tickets were sold
1) 400+40+3
2) 90+2
3) 100+1
