The ratio of money in Terry's bank account to Faye's bank account was 3:7. Terry then put £220 in his account and Faye withdrew
Nesterboy [21]

Answer:

£910

Step-by-step explanation:

let 3x and 7x be the initial amounts in their accounts, then after alterations

Terry has 3x + 220

Faye has 7x - 300

After these changes the amounts are equal, hence

7x - 300 = 3x + 220 ( subtract 3x from both sides )

4x - 300 = 220 ( add 300 to both sides )

4x = 520 ( divide both sides by 4 )

x = 130

Faye initially had 7 × £130 = £910 in her account

NEED HELP FAST!!!!! The graph below compares plant height to the age of the plant, in weeks. Y=1.3x-0.8 Based on the graph, whic
salantis [7]

Answer:

C) 6 inches

Step-by-step explanation:

Given function:

Y=1.3x-0.8

The function compares plant height in inches to the age of plant in weeks.

So, we can say

Y represents height of plant in inches.

x represents age of the plant in weeks.

In order to predict the height of the plant in 5 weeks, we will plugin x=5 in the given function and evaluate Y

⇒ Y=1.3(5)-0.8

⇒ Y=6.5-0.8

⇒ Y=5.7 inches

Thus the approximate height of plant in 5 weeks would be \approx 6 inches
