4 x 0.90 = £3.60
£13.50 - £3.60 = £9.90
0.9 + 0.75 = £1.65
£9.90/£1.65 = 6
They bought 6 ice cream cones

Steve and carol live 405 miles apart, they start at the same time and travel toward each other, Steve speed is 6mph greater than
babymother [125]

Answer:

Speed of Carol is 78 mph and that of Steve is 84 mph.

Step-by-step explanation:

Let the speed of Carol is x mph and that of Steve is (x + 6) mph.

If they move towards each other with that speed, then the resultant speed will be (x + x + 6) = (2x + 6) mph

With this resultant speed, they cover 405 miles in 2.5 hours.

So, 2x + 6 = \frac{405}{2.5} = 162

⇒ 2x = 156

⇒ x = 78 mph

So, speed of Carol is 78 mph and that of Steve is (78 + 6) = 84 mph. (Answer)

2 320 is invested for two years
Vinil7 [7]

Answer:

<h3><em>which is a better investment and by how much</em></h3>

<em><u>It's</u></em><em><u> 14% p.a simple interest</u></em>

Step-by-step explanation:

<em><u>Simple interst:</u></em>

Answer:

I = $ 649.60

Equation:

I = Prt

Calculation:

First, converting R percent to r a decimal

r = R/100 = 14%/100 = 0.14 per year,

then, solving our equation

I = 2320 × 0.14 × 2 = 649.6

I = $ 649.60

The simple interest accumulated

on a principal of $ 2,320.00

at a rate of 14% per year

for 2 years is $ 649.60.

<em><u>Compound </u></em><em><u>interest</u></em>

Answer:

A = $2,945.78

A = P + I where

P (principal) = $2,320.00

I (interest) = $625.78

Calculation Steps:

First, convert R as a percent to r as a decimal

r = R/100

r = 12/100

r = 0.12 rate per year,

Then solve the equation for A

A = P(1 + r/n)nt

A = 2,320.00(1 + 0.12/12)(12)(2)

A = 2,320.00(1 + 0.01)(24)

A = $2,945.78

What is the solution to this equation? x - 15 = 8
Pavlova-9 [17]

Answer:

\huge{\boxed{ \sf{x = 23}}}

Step-by-step explanation:

\sf{x - 15 = 8}

Since, we are asked to find the value of x . move 15 to right hand side and change its sign.

⇒ \sf{x = 8 + 15}

Add the numbers : 8 and 15

⇒ \sf{x = 23}

The value of x is 23.

Hope I helped!

Best regards! :D
