Answer:
n = -2
Step-by-step explanation:
5n - 16 - 8n = -10
Combine like terms
-3n -16 = -10
Add 16 to each side
-3n-16+16 = -10+16
-3n = 6
Divide by -3
-3n/-3 = 6/-3
n = -2
Answer:
a) Cat
b) 4 (unless there is a key that says otherwise)
c) 3 more people
Step-by-step explanation:
a) It has the least number of shapes (only 5)
b) Cat has 1 small square which stands for 1 person and 4 small squares put together make a big square so a big square is 4 people. Unless a key says that a small square is more or less 1, then it should be 4.
c) If one big square is 4 people, then there are 10 people for giraffes and 7 people for dogs. 10 - 7 = 3 more people.
Answer:
15.59 feet
Step-by-step explanation:
We need to find BC and CD
First find BC
We can use the Pythagorean theorem
AB^2 + BC^2 = AC^2
11^2 + BC^2 = 13^2
121 + BC^2 =169
Subtract 121 from each side
121-121+BC^2 = 169-121
BC^2 = 48
Take the square of each side
sqrt(BC^2 ) = sqrt( 48)
BC = 6.92820323
then we need to find CD
We can use the Pythagorean theorem
CD^2 + DE^2 = CE^2
CD^2 + 5^2 = 10^2
CD^2 + 25 =100
Subtract 25 from each side
CD^2 + 25-25 =100-25
CD^2 = 75
Take the square of each side
sqrt(CD^2 ) = sqrt( 75)
BC = 8.660254038
BD = BC +CD
= 6.92820323 + 8.660254038
15.58845727
Answer:
1144 o 286
Step-by-step explanation:
Si pregunta por la cantidad de personas que se pesaron, la respuesta es (8/10) * (1430) = 8 * 143 = 1144.
Si desea saber cuántas personas no se pesaron, la respuesta es 1430* (2/10) = 286
X+0.0825x=216.5
1.0825x=216.5
x=216.5 / 1.0825
x=200
Answer: C.) x=200
