Answer:
<h2><em><u>
m = 20</u></em></h2><h2><em><u>
a = 48</u></em></h2><h2><em><u>
These are the answers.</u></em></h2>
Step-by-step explanation:
1. m/-8 = -2.5
*-8 = *-8
m = -2.5*-8
m = 2.5*8
<em><u>m = 20</u></em>
2. 7/8a = 42
*8 *8
7a = 336
/7 /7
a = 336/7
<em><u>a = 48</u></em>
<em><u></u></em>

Answer:
B *second one down.
Step-by-step explanation:
EF = 1/2(AB + CD)
x+5 = 1/2 (2x + 2 + 2x+4) Combine the like terms on the right.
x+5 = 1/2 (4x + 6) Remove the brackets.
x+5 = 1/2*4x + 1/2*6
x+5 = 2x + 3 Subtract x from both sides
5 = 2x-x + 3
5 = x + 3 Subtract 3 from both sides
5-3 = x
x = 2
EF = x + 5
EF = 2 + 5
EF = 7
The answer is B
Answer:
smallest number of chickens= 3
Step-by-step explanation:
In this question the given formation is:
two chickens in front of a chicken
the total number of chickens are 3
two chickens behind a chicken
the total number of chickens are 3
a chicken between two chickens
the total number of chickens are 3
So, the smallest number of chicken that can be required to make this formation will be 3.
So, if we consider that the chickens are walking in a straight line, two (2nd and 3rd) chickens will be behind the 1st chicken, two chickens( 1st and 2nd) will be in front of the last (3rd) chicken and one (2nd) chicken is in the middle of two (between 1st and 3rd) chicken.
