“Jesse bought 10 more pencils than erasers”       means    P = 10 + E

 “A pencil costs $0.15”   means that     $0.15*P was spent on pencils

 “an eraser costs $.22”    means that    $0.22*E was spent on erasers

 “He paid a total of $4.46”    means that   $0.15*P + $0.22*E = $4.46

15*(10+E)   +   22*E    =   446

                       150 + 37E = 446

                          37E = 296

                              E = 8   Jesse bought 8 erasers

Vcyl = Vcone
pi×x^2×y = 1/3×pi×(3x)^2 (h)
pi's cancel--> x^2•y = 3x^2 (h)

PLEASE HELP MEEEEE
Elena-2011 [213]

Answer:

a = 36 and a = 27

Step-by-step explanation:

The geometric mean of two numbers is the square root of the product of the two numbers.

Say for example we have the numbers x and y, the geometric mean z is mathematically;

z = √xy

For the first question, our z is 12, x and y are 4 and a respectively.

12 = √4a

square both sides

144 = 4a

a = 144/4

a = 36

For the second question

z is 9, x and y are 3 and a respectively

9 = √3a

square both sides

81 = 3a

a = 81/3

a = 27

Solve the equation below for x.<br> сх — 4 = 7
RoseWind [281]

Answer:

x = 11/c

Step-by-step explanation:

To solve this equation for x, we simply need to apply equation operations and isolate the x variable.

cx - 4 = 7

cx - 4 + 4 = 7 + 4

cx = 7 + 4

cx = 11

cx * (1/c) = 11 * (1/c)

x = 11 * (1/c)

x = 11/c

Cheers.
