Answer:

He should buy the 4 x 10 rug because it has the larger area.

Step-by-step explanation:

To find the area of a rectangle or square, you multiply length by width (A=l x w). 5x7=35 and 4x10=40, so 4 x 10 has the bigger area.

Alvin is 12 years younger than Elga. The sum of their ages is 86 what is Algas age
Ede4ka [16]

9514 1404 393

Answer:

  • Alvin: 37
  • Elga: 49

Step-by-step explanation:

Let 'a' and 'e' represent Alvin's and Elga's ages, respectively.

  a = e-12 . . . . . Alvin is 12 years younger

  a + e = 86 . . . the sum of their ages is 86

__

Substituting for 'a' gives ...

  (e -12) +e = 86

  2e = 98

  e = 49

  a = 49 -12 = 37

Alvin is 37; Elga is 49.

Dan's father is an orange farmer and he brought 32 orange it to class today if each child got four oranges and five children did
Eddi Din [679]

Answer:  There are 13 children.


Step-by-step explanation:

1. Let's call x the number of children in the classroom. We know that each child received 4 oranges, except 5 of them.

2. There were 32 oranges in total.

3. We can write this problem as an equation that represents the number of oranges distributed, as follows:

4(x-5)=32

4. Now we solve the equation to find the value of x:

x-5=\frac{32}{4}

x-5=8

x=13

5. There are 13 children in the classroom. 8 of them received oranges and the rest did not.
