Transitive property of equality
d=3c
3C means 3 times whatever the value of "C". Similary, 5S means 5 times whatever the value of "S" is.
80°F = 262/3°C To convert Celsius to Fahrenheit, the formula is F = 9/5C + 32. If the Fahrenheit reading is 3 times the Celsius reading then F = 3C, so 3C = 9/5C + 32 : 6/5C = 32 : C = 262/3. Then F = 3C = 3 x 262/3 = 80
This does not sound like an equation. This sounds like evaluating an algebraic expression. 3C means 3 times the value of C (which you have given as 21) then subtract 15. 3 x 21 - 15 = 48
12bc - 4bd - 15xc + 5xd = 4b(3c - d) - 5x(3c - d) = (3c - d)(4b - 5x)
3c-d
Transitive property of equality
No, 3c ( c ) = 4c

2a*4b*(-3c) = ? 2 * 4 * -3 * a * b * c = ? -24abc
d=3c
3C means 3 times whatever the value of "C". Similary, 5S means 5 times whatever the value of "S" is.
Sum means to add.. so the equation would look like 3(c+d) or (c+d)*3. You could also add them separately. 3c+3d Hope that helps!
3c+6=18 3c+6-6=18-6 3c=12 3c÷3=12÷3 c=4
The circumference is tripled.C=pi*d, so pi*(3d) = 3C, where d is diameter and C is circumference.
3c-7 = -4
