Răspuns:

1

Explicație pas cu pas:

Fie numărul = x

x + 4 = e - - (1)

e * 4 = f - - - (2)

Ecuația 2 - 4 împărțită la 4 = 4

(f - 4) / 4 = 4

Crucea se înmulțește

f - 4 = 16

f = 16 + 4

f = 20

Rezultatul 1 împărțit la 4 este egal cu 4

Prin urmare,

e = f / 4

f = 20

e = 20/4

e = 5

De la (1)

x + 4 = e

x + 4 = 5

x = 5 - 4

x = 1

Mike and talia each make a scale drawing of the right side of their house. The scale of the side of the actual house to Mikes dr
Nutka1998 [239]

The width and height of Talia's Scale drawing are :

  • Width = 4.35 in
  • Height = 5.7 in

We can obtain the actual length of the side of the house from Mike's drawing :

  • Mike's scale = 3 ft to 1 in

Actual measurements:

  • Scale ratio × model drawing
  • Height, h = 9.5 × 3 = 28.5 feets
  • Width, w = 7.25 × 3 = 21.75 feets

Measurement of Talia's Scale drawing :

  • Talia's scale = 5 ft to 1 in
  • Actual measurement ÷ scale
  • Height = 28.5 ÷ 5 = 5.7 in
  • Width = 21.75 ÷ 5 = 4.35 in

The width and height of Talia's scale drawing are 5.7 and 4.35 respectively.

The table shows transactions from five different bank accounts. Fill in the missing numbers. ( THE IMAGE ATTACHED PLEASE)
velikii [3]

Answer:

Part 1) A=80

Part 2) B=-25

Part 3) C=-40

Step-by-step explanation:

we know that

The old account balance plus the transaction amount is equal to the new account balance

The transaction amount can be a positive number (example a deposit) or a negative number (example a withdrawal)

Part 1) Find the value of A

432+A=512

solve for A

subtract 432 both sides

A=512-432=80

Part 2) Find the value of B

75-100=B

solve for B

-25=B

Rewrite

B=-25

Part 3) Find the value of C

C+52=12

solve for C

subtract 52 both sides

C=12-52

C=-40
