Answer:
- 20 and 31
Step-by-step explanation:
Solve the given equations simultaneously to find x and y
2x + y = 23 → (1)
4x - y = 19 → (2)
Adding the 2 equations term by term will eliminate y
6x + 0 = 42
6x = 42 ( divide both sides by 6 )
x = 7
Substitute x = 7 into either of the 2 equations and solve for y
Substituting into (1)
2(7) + y = 23
14 + y = 23 ( subtract 14 from both sides )
y = 9
Then
x - 3y = 7 - 3(9) = 7 - 27 = - 20
5y - 2x = 5(9) - 2(7) = 45 - 14 = 31
The Mathematical statement which includes addition, subtraction and multiplication:
→4+8x(18+5)+18+(8x4x5)+0x(5+3)
= 4 + 8 × 18 + 8 × 5 + 18 +(32 × 5) + 0 × 5 + 0 × 3 → [ Using distributive property which is , a × (b +c)= a × b + a × c, and (p × q × r)= [ (p × q) × r]
= 4 + 144 + 40 + 18 + 160 + 0 + 0
= 148 + 58 + 160 → [ Using addition property of natural numbers, as you can add natural numbers in any order]
= 206 + 160
= 366
3 times 0.85 + 2 times 1.89 equals 6.33
Divide 6.33 by 2 equals $3.165
5 minus 3.165 = $1.835
Which $1.835 is your change you receive
Answer:
<h2>The scale factor is 285.7143 ≅ 286.</h2>
Step-by-step explanation:
The square sheet has an area of 100 square meters.
Hence, the width of the sheet is 
meters.
The scale factor is needs to be in such a way, so that the film's wide will be match perfectly with the square sheet. Hence, 35x millimeters = 10 meters = 10000 millimeters .
