She will have to save for 11 weeks

Answer:

11 weeks

Step-by-step explanation:

she already has $8 so subtract that from $57.50:

57.5 - 8 = 49.5

so she needs to save $49.5. set up the problem like this, where x is the number of weeks needed:

4.5x = 49.5

divide each side by 4.5:

x = 11

it will take her 11 weeks.

Zhi bought 18 tickets for games at a fair. Each game requires 3 tickets. Zhi wrote the expression 18 – 3g to find the number of
mart [117]

Answer: In zhi's equation, the 18 is the initial amount of tickets, and the 3g means 3 times the amount of games.  

Diegos equation is the same, but write in factorised form. The 3 multiplies with the 6 to create 18, and the 3 multiple with the g to create 3g

36=4/9d what does d equal
soldier1979 [14.2K]

Answer:

d = 81

Step-by-step explanation:

Solve for d:

36 = (4 d)/9

Hint: | Reverse the equality in 36 = (4 d)/9 in order to isolate d to the left hand side.

36 = (4 d)/9 is equivalent to (4 d)/9 = 36:

(4 d)/9 = 36

Hint: | Multiply both sides by a constant to simplify the equation.

Multiply both sides of (4 d)/9 = 36 by 9/4:

(9×4 d)/(4×9) = 9/4×36

Hint: | Express 9/4×4/9 as a single fraction.

9/4×4/9 = (9×4)/(4×9):

(9×4)/(4×9) d = 9/4×36

Hint: | Express 9/4×36 as a single fraction.

9/4×36 = (9×36)/4:

(9×4 d)/(4×9) = (9×36)/4

Hint: | Cancel common terms in the numerator and denominator of (9×4 d)/(4×9).

(9×4 d)/(4×9) = (4×9)/(4×9)×d = d:

d = (9×36)/4

Hint: | In (9×36)/4, divide 36 in the numerator by 4 in the denominator.

36/4 = (4×9)/4 = 9:

d = 9×9

Hint: | Multiply 9 and 9 together.

9×9 = 81:

Answer: d = 81
