When it's laid out like that. 2 division statements on either side with one unknown variable you just cross multiply really easy
5 x 24 / 6 = 20
Take the number that's on the same position of the x thats 5 then multiply it to the numerator or denominator of the x thats 24 then divide it to its denominator thats 6
Answer:
c) πr2h is the answer
Step-by-step explanation:
Both equal to y so set equal to each other
4x+4=x²+4
minus 4 both sides
4x=x²
minus 4x both sides
0=x²-4x
factor
0=x(x-4)
set each to zero
0=x
0=x-4
4=x
x=4 and 0
2 solutions
Answer:
yes
Step-by-step explanation:
Remark
All three sides are equal in an equilateral triangle.
y + 5 = x + y - 5 . . . . . . .(1)
y +5 = 2x - 7 . . . . . . . . .(2)
For 1
Subtract y from both sides.
5 = x - 5 . . . . . . . . . . . Add 5 to both sides.
x = 10
x + y - 10 = 2x - 7 . . . .Put x = 10 into this equation
10 + y - 10 = 2*10 - 7
y = 20 - 7
y = 13
In 2x - 7, let x = 10
2(10) - 7 = 20 - 7
