Matthew has $45 in savings and plans to save an additional $30 each month. How long will it take him to save enough for a $250 b
Semenov [28]

Answer:

Part A. It will take him 7 months

Part B. The equation is 30 - 45x + 250

Step-by-step explanation:

Part A. the answer is 7 because in 6 months Matthew will have $225 and if you add 30 you get $255.

Part B. It's the answer because its the only one that makes sense. 250 = 450 + 30. Its 45 not 450. 250 = 30.2 + 45. It's 30 not 30.2 and 30 30 well 30 30 doesn't make sense either.

chu vi của một hình chữ nhật là 240 cm. Tính diện tích hình chữ nhật đó, biết tỉ số độ dài hai cạnh là 5 và 7
ch4aika [34]
(-) Tỉ số độ dài 2 cạnh là 5 và 7
=> Chiều rộng = 5:12, chiều dài = 7:12
(-) Chu vi = 240 suy ra tổng chiều dài + chiều rộng = 240 : 2 = 120
(-) Chiều rộng = 120 x 5 : 12 = 50
Chiều dài = 120 x 7 : 12 = 70
(-) Diện tích = 50 x 70 = 3500
