Mathematics
1 answer:
Fantom [35]2 years ago
5 0

Answer:

$63

Step-by-step explanation:

so we want to find 9/9 of her allowance, which is 100%

we could use a proportion:

let 'a' = full allowance

\frac{28}{1} ÷ \frac{4}{9} = \frac{a}{1} ÷ \frac{9}{9}

when we divide fractions we multiply by the reciprocal to get:

28 x 9/4 = a

a = 252/4

a = 63

What is the mixed number for 56/10
andre [41]
Well, 10 can go into 56, 5 times, so your whole number would be 5.
Then 50 (where did i get 50 from? 5 times the ten is 50) minues 56 is 6. So it would be : 
5 and 6/10 (your denominator stays the same)
But it needs o be simplafied to its lowest terms. They are both divisable by 2, SOO 6 divided by 2 is 3, and 10 divided by 2 is 5 So, your new fraction is:
5 and 3/5 in which it cant be simplafied anymore.
<em>~ 5  3/5 </em><em>is your answer :)</em>

Dudley is biking. He wants to cover 40 miles. If he travels 30 miles every 2 ours, what is the equation of a line that models y,
fgiga [73]

Answer:

y=40-15x

Step-by-step explanation:

Let x represent the number of hours.

We have been given that Dudley travels 30 miles every 2 hours, so distance covered in each hour by Dudley would be:

.

Since Dudley travels 15 km per hour, so distance covered in x hours would be 15x.

We have been given that Dudley wants to cover 40 miles. So we can represent our given information in an equation as:

, where, y represents number of miles he has left to travel, after biking x hours.

5x + 6y = 20 , 8x - 6y = -46
serg [7]

Answer:

5x + 6y = 20_____(1)

8x - 6y = -46_____(2)

Solving simultaneously:

Eqn(1) + Eqn(2)

5x + 8x + 6y + (-6y) = 20 + (-46)

13x = -26

x = -2

substituting this into Eqn (1):

5(-2) + 6y = 20

-10 + 6y = 20

6y = 30

y = 5

hence:

x = -2,y = 5.
