Abiodun and taiwo share 735 naira between them so that abiodun get 95naira more than taiwo find how much money each gets

DerKrebs [107]

Answer:

Abiodun gets - <u>415 naira</u>

Taiwo gets -<u> 320 naira</u>

Step-by-step explanation:

Let us consider x and y as Abiodun and Taiwo,

Therefore , acccording to the question , equation formed will be -

$x+y=735$ naira ------ 1

and

$x=y+95$

$x-y=95$ ------2

From equation 1 and 2, we get

$2x=830$

$x=\frac{830}{2}$

$x=415$ naira (that is Abiodun share)

now , Calculating Taiwo share from equation 1

$x+y=735\\415+y=735$

$y=735-415$

y = 320 naira (that is Taiwo share )

Therefore , Share of Abiodun = 415 naira

Share of Taiwo = 320 naira

Find 5 points that satisfy the equation y= 12+2x

Goshia [24]

We start by finding the intercept of the line: what does y equal when x=0? and what does x equal when y=0?
• intercept in x
y = 12 + 2x
0 = 12 + 2x
-12 = 2x
-6 = x
• intercept in y
y = 12 + 2x
y = 12 + 2(0)
y = 12 + 0
y = 12
Now we find three more points giving y a value and finding x
y = 12 + 2x
2 = 12 + 2x
2-12 = 2x
-10 = 2x
-5 = x

y = 12 + 2x
6 = 12 + 2x
6 - 12 = 2x
-6 = 2x
-3 = x

y = 12 + 2x
14 = 12 + 2x
14 - 12 = 2x
2 = 2x
1 = x

Notice how I gave y even numbers as values since we would have to divide with 2 at the end.

Sol. {(-6,0)(0,12)(-5,2)(-3,6)(1,14)}

John and 2 friends are going out for pizza for lunch. They split one pizza and 3 large drinks. Thepizza cost $12.00. They spend

tatiyna

It should cost $1.65 for each large drink.

You subtract $12 to $16.95 and that would give you 4.95 and divide it to the number of drinks they bought which is 3 and that would give you $1.65

Answer:

7.$95 8. $112.50

Step-by-step explanation:

50 divided by 100 is 0.5, then times by 90 is 45.

45 plus 50 is 95.

$150/4=$37.50

$150-$37.50=$112.50
