Hello,
Let's assume a,b,c the 3 numbers
a+b+c=62
b=a-4
c=4*a
==>a+(a-4)+4a=62
==>6a=66
==>a=11
b=11-4=7
c=4*11=44
The 3 numbers are 11;7;44
Proofs:
11+7+44=62
7=11-4
44=4*11
Answer: height = 17.5cm
Step-by-step explanation: Peter mixes blue and yellow paint in the ratio 2:3, which means:
x = 12.6L
The container is full with the two paints, so total volume:
V = 12.6 + 8.4
V = 21L
Knowing that 1L = 1dm³ and sides of cuboid is measure in cm:
V = 21dm³ = 21000cm³
Volume of a cuboid is calculated as:
V = width*length*height
Height of the container is
height =
height =
height = 17.5cm
The height of the container is 17.5cm.
Use PEMDAS. Parenthesis. Exponents. Multiplication. Division. Addition. Subtraction. there are no parenthesis so that doesn't matter. there are no exponents. but there is multiplication. 8×7 = 56. so now the equation is 56+4×2-11-7×4. you still have multiplication so now we do 4×2 which is 8. the equation is now 56+8-11-7×4. you still have multiplication so now do 7×4 which is 28. the equation is now 56+8-11-28. there is no multiplication. or division. next is addition. 56+8 which is 64. now the equation is 64-11-28. next you do subtraction. 64-11 which is 53. now the equation is 53-28 which is 25. 25 is the answer. I hope this helped ☺️
265/99, is what I think but I’m not sure
Do you need an equation?
y=2x+10
2x represents each hour, 10 represents renting fee
