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

£300 from her account. They now had the same amount in their accounts. How much did Faye initially have?

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

How do you solve 11x=24+8x
fgiga [73]
First bring all the x's to one side.
then subtract them.
then divide 24 by 3 to get the x alone and get your answer.

11x-8x=24
3x=24
x=8

Help plz,BIG POINTS,also plz show me the steps as best as possible
Sidana [21]

Answer:

The correct answer is option 3.

Step-by-step explanation:

Given : ΔPQR, QM is altitude of the triangle

PM  = 8

MR = 18

To find = QM

Solution :

PR = 8 + 18  = 26

Let, PQ = x  , QR = y, QM = z

Applying Pythagoras Theorem in ΔPQR

PQ^2+QR^2=PR^2

x^2+y^2=(26)^2..[1]

Applying Pythagoras Theorem in ΔPQM

PM^2+QM^2=PQ^2

8^2+z^2=(x)^2..[2]

Applying Pythagoras Theorem in ΔQMR

MR^2+QM^2=QR^2

18^2+z^2=(y)^2..[3]

Putting values of x^2 and y^2 from [2] and [3 in [1].

8^2+z^2+18^2+z^2=(26)^2

2z^2=(26)^2-(8)^2-(18)^2

2z^2=288

z^2=144

z = ±12

z = 12 = QM ( ignoring negative value)

The length of QM is 12.

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline . If Mr. Adams spent $36.25 on 12.5 gal
Maslowich

Answer:

Step-by-step explanation:

At Greg's Gas Station premium gasoline costs $0.14 more per gallon than regular gasoline .

Let the cost of regular gasoline be $x per gallon, then the cost of premium gasoline per gallon will be x + 0.14

If Mr. Adams spent $36.25 on 12.5 gallons of regular gasoline, it means that 12.5x = 36.25

x = 36.25/12.5 = $2.9

The cost of regular gasoline is $2.9 per gallon

Therefore, cost of premium gasoline per gallon will be 2.9+ 0.14 = 3.04

if he bought 12.5 gallons of premium gasoline instead, he would have paid

12.5× 3.04 = $38

The amount that he would have spent more will be

38 - 36.25 = $1.75

What’s the answer to 14?
vfiekz [6]

Answer:

  • |t -(-5)| = 1.5
  • [-6.5, -3.5] = [minimum, maximum]

Step-by-step explanation:

The magnitude of the difference between the temperature (t) and -5 will be 1.5 at the limits:

  |t -(-5)| = 1.5

This is equivalent to two equations:

  • t +5 = -1.5
  • t +5 = 1.5

In each case, the equation is solved by subtracting 5 from both sides:

  • t = -6.5 . . . . minimum allowed temperature
  • t = -3.5 . . . . maximum allowed temperature
