Mathematics
1 answer:
Ganezh [65]3 years ago
5 0

Answer:

3) 0.14

5) 2/5

Step-by-step explanation:

3) Ok, so, the equation for number 3 would be 2.24/16, which would be 0.14.

5) Reducing fractions is simplifying them, so divide 40 and 100 by 10 each, which gets 4/10. then, divide each by 2 to get 2/5, which is the most it could be reduced.

The area of a rectangle is 44 square feet. The base of the rectangle is 11. Find the height, then find the perimeter
Alecsey [184]

Answer:

4

Step-by-step explanation:

Since the area of a rectangle = Length times Breath

We are just going to divide your are by breadth which is

Let your length become y

= y × 11 = 44

to get your answer you move× 11 over the equal to sign which becomes ÷11 because any sign that cross the equal to sign changes which is equal to

y = 44÷11

y = 4

what i did was that i divided 44 by 11 which is equal to 4

DochEvi [55]

Answer:

(-2,3)

Step-by-step explanation:

Step 1. Isolate x for 3x + 5y = 9

3x + 5y - 5y = 9 - 5y

3x = 9 - 5y

3x/3 = 9/3 - 5y/3

x= (9-5y)/3

Step 2. Simplify

-3*((9-5y)/3) + 3y = 15

-3*((9-5y)/3) = 9 - 5y = -(-5 + 9) + 3y

-9+5y+3y

-9+8y = 15

Step 3 Isolate y for -9+8y=15

-9+8y+9=15+9

8y=24

8y/8 = 24/8

y=3

Step 4 Substitute y = 3

x = (9-5*3)/3

-(6/3) = (-2)

x = -2
