Suppose you got 8 mangoes and 3 apples for $18 and 3 mangoes and 5 apples for $14.50.How many does each mango and each apple cos
lidiya [134]
M = mangoes
a = apples

8m + 3a = 18               Equation 1
3m + 5a = 14.50          Equation 2
Lets multiply equation 1 by 5 and equation 2 by 3
The new equations are:
45m + 15a = 90
9m   + 15a = 43.5

Subtract them and get:
36m = 46.5
m     = 1.30     Divide both sides by 36

Substitute m into equation 2 (either is fine, but choose the easier one)
3(1.30) + 5a = 14.5
3.9     + 5a  = 14.6        Expand the bracket
5a = 10.6                      Minus both sides by 3.9
a   = 2.12                      Divide both sides by 5

Mangoes cost $1.30
Apples cost $2.12 (more like $2.10)

I feel that my working out is wrong, but that is how you work out the answer.

Can someone please answer this question please answer it correctly and please show work please help me I need it
JulsSmile [24]

Answer:

B

Step-by-step explanation:

We'll use Natasha's location as 0 on a number line. To the left of her, 51/20 would be negative and 25/4 would be positive.

To find how far apart the dogs are, we would need to add the absolute value of each number:

|-51/20| + |25/4| however, this can also be rewritten as:

25/4 - (-51/20)

What is the value of x? Then determine the measure of each angle.
IrinaK [193]

<u>Answer:</u>

x = 14°   ||       each angle has 108°

<u>explanation:</u>

first we need to find the total interior angle of this shape:

formula: ( n - 2 ) * 180  ..............where n is the number of sides

( 5 -2 ) * 180

540°

if all sides in the shape are equal, they must have same angle of 9x -18

5 ( 9x -18 ) = 540°

9x -18° = 108°

9x = 108° + 18°

9x = 126°

x = 14°

So each angle has: 9x - 18

                                9(14) - 18

                                108°
