Answer:
the answer is -3
Step-by-step explanation:
-2(4x+4) becomes -8x+-8 then becomes -8x+-8+-4 you get -8x+-12 you add 12 to -12 it then gives you -8x=24 that makes it -x=3 you devide that by -1 and x=-3
Let's solve your equation step-by-step. x2+5x−6=0
Step 1: Factor left side of equation. (x−1)(x+6)=0
Step 2: Set factors equal to 0. x−1=0 or x+6=0
x=1 or x=−6
Answer:
$931.25
Step-by-step explanation:
Given a bond is quoted at
let the Face value of the amount = $1000
therefore, the price/cost =
= $931.25
Therefore, the bond quoted at is equal to $931.25 per 1000 of the face value.

The number of students who attended the museum opening is 80.
A linear equation is an algebraic equation of degree one. In general, the variable or the variables(in the case of a linear equation in two variables) the variables are x and y.
Given, A group of 100 people, some students and some faculty, attended a museum opening.
Assuming no. of students to be x and no. of faculty to be y.
∴ x + y = 100...(i)
Each student paid $10 per person for entrance to the museum and each of the faculty paid $25 per person for entrance and the total cost is $1300.
∴ 10x + 25y = 1300...(ii)
Now multiplying eqn(i) by 10 we get 10x + 10y = 1000...(iii)
Subtracting eqn(iii) from eqn(ii) we get 15y = 300 ⇒ y = 20 and substitting value of y in eqn(iii) we get x = 80.

STUDENTS X 10
FACULTY 100-X 25
10X + 25(100-X) = 1300
10X + 2500 -25X = 1300
10X - 25X = -2500 + 1300
-15X = -1200
15X = 1200
X = 1200/15

trees in the park. How many sycamore trees
are in the park?
Answer:
40 sycamore trees
Step-by-step explanation:
We can use the following equation to calculate the total number of sycamore trees in the park:
75% of Total sycamore tree = 30 sycamore tree
0.75 of Total sycamore tree = 30 sycamore tree
Therefore, there are 40 sycamore trees in the park.
Let’s assume that the number of sycamore trees in the park is x. According to the problem statement, 30 sycamore trees make up 75% of all sycamore trees in the park. This can be expressed as:
30 = 0.75 * x
Solving for x, we get:
x = 30 / 0.75
x = 40
Therefore, there are 40 sycamore trees in the park.
