Answer:

98

2+3=2*[3+(2-1)]=8

3+7=3*[7+(3-1)]=27

4+5=4*[5+(4-1)]=32

5+8=5*[8+(5-1)]=60

6+7=6*[7+(6-1)]=72

therefore

7+8=7*[8+(7-1)]=98

x+y=x[y+(x-1)]=x^2+xy-x

Answer:

2*3 + 3* 7 = 27

4*3 + 5* 4 = 32

....

7*6 + 8*7 = 98

or it could be :

2+3-1 = 5 -1 = 4 *2 = 8

3+7-1 = 10-1 = 9 *3 = 27

4+5-1 = 9-1 = 8 * 4 = 32

5+8-1 = 13-1 = 12 * 5 = 60

6+7-1 = 13-1 = 12 *6 = 72

7+8-1 = 15-1 = 14*7 = 98

Ama's age is two thirds that of her elder sister. Four years ago ama's age was half the sister's. How old is the sister?
Westkost [7]

Answer:

12

Step-by-step explanation:

Ama's sister is 12 now and Ama is 8. 8/12 simplified is 2/3.

Four years ago Ama's would have been 4 and her sister would have been 8. 4/8 simplified is 1/2.

The equations:

(Ama is a)

(Ama's sister is s)

a = (2/3)s

a - 4 = (1/2)(s - 4)

Step one:

You would substitute the first equation into the second equation to get

(2/3)s - 4 = (1/2)(s - 4)

Step two:

Multiply by 6 to get rid of the fractions to get

4s - 24 = 3(s - 4)

Step three:

Simplify to get

4s - 24 = 3s - 12

Step four:

Subtract 3s and add 24 to get

s = 12

Step five:

Input the s value into the first equation to get

a = (2/3)(12) = 8

A car travelled a distance of D =320 kilometers for T =5.0 hours at a constant rate use the formula D =R. T To find the speed (R
motikmotik

The speed of car is 64 kilometer per hour

<em><u>Solution:</u></em>

Given that car travelled a distance of D = 320 km for T = 5.0 hours

To find: speed (R) of the car in km per hour

<em><u>Formula given:</u></em>

D = R. T

where "D" is the distance

"R" is the speed of car

"T" is the time taken

<em><u>Substituting the given values in above formula we get,</u></em>

320 = R \times 5.0\\\\R = \frac{320}{5}\\\\R = 64

Thus the speed of car is 64 kilometer per hour

We cannot round the answer to nearest tenth, since answer is not in decimal
