Answer:

B & C

Step-by-step explanation:

For A,

Base area(A) = length x breadth = 2m x 5m

Base area(A) = 10 m²

Similarly,

Base area(B) = 2m x 3m = 6m²

Base area(C) = 3m x 2m = 6m²

Base area(D) = 9m x 2m = 18m²

Note that 6m²=6m², B and C have same base area

Answer:

[tex]d = 39[/tex]

Step-by-step explanation:

1) Multiply both sides by d.

[tex] \frac{20}{13} d = 60[/tex]

2) Simplify 20/13d to 20d/13.

[tex] \frac{20d}{13} = 60[/tex]

3) Multiply both sides by 13.

[tex]20d = 60 \times 13[/tex]

4) Simplify 60 × 13 to 780.

[tex]20d = 780[/tex]

5) Divide both sides by 20.

[tex]d = \frac{780}{20} [/tex]

6) Simplify 780/20 to 39.

[tex]d = 39[/tex]

Therefor, the answer is d = 39.

Answer:

[tex]\frac{2}{3}[/tex]

Step-by-step explanation:

Fraction of the floats that belongs to sports team = [tex]\frac{6}{18}[/tex]

                                                                                  = [tex]\frac{1}{3}[/tex]

Therefore, fraction of floats that were not from a sports team = 1 - fraction of floats that belongs to sports team

= 1 - [tex]\frac{1}{3}[/tex]

= [tex]\frac{2}{3}[/tex]

[tex]\frac{2}{3}[/tex]rd fraction of Parade Float were not from a sports team.

Answer:

The sister is 25.5. The brother is 28.5.

Step-by-step explanation:

25.5 + 28.5 = 54.

The boy's age is 9.

The girl's age is 12.

An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.

Example: 2 + 3x + 4y = 7 is an expression.

We have,

Boy's age = x

Girl's age:

y = x + 3

Now,

x (x + 3) = 54

x² + 3x - 54 = 0

x² + (9 - 6) - 54 = 0

x² + 9x - 6x - 54 = 0

x(x + 9) - 6(x + 9) = 0

x - 6 = 0

x = 6

x + 9 = 0

x = -9 ( cannot be negative)

Now,

x = 9

Boy's age = 9

Girl's age = 9 + 3 = 12

Thus,

The boy's age and the girl's ages are 9 and 12.

Answer:

From 2008 to 2016

Step-by-step explanation:

Answer:

7/10

Step-by-step explanation:

To solve this, first find how many of the cards or even. There are 5 even cards out of these 10 cards, so we have the fraction 5/10. Next, we can see that there are 4 pink cards. So, we also have the fraction of 4/10. Then, add these two fractions.

5/10 + 4/10 = 9/10.

But, since the pink 8 card and the pink 10 card are both pink and even, they were counted twice. So, we need to subtract 2/10 from 9/10. This is 7/10.
