Answer:
All real numbers
Step-by-step explanation:
Distribute the -2 to the parentheses:
-12d - 6 = -2(d + 3) - 10d
-12d - 6 = -2d - 6 - 10d
Add like terms:
-12d - 6 = -12d - 6
Since each side is equivalent to -12d - 6, the answer is all real numbers
Answer:
This is true for any value of d. (d ∈ Set of All Real Numbers (I couldn't find the symbol))
Step-by-step explanation:
1. Simplify both sides. You cannot simplify -12d - 6, but you can simplify -2(d + 3) - 10d. Use the distributive property to simplify this. It would be -2d + -2 * 3 -10d, which is equal to -12d - 6. If you simplify both sides, you would get that d=d, which would be true for all values of d, which means that d is equal to all real numbers, meaning that for any value for d, this would be true (d ∈ Set of All Real Numbers (I couldn't find the symbol)).

Answer: 225 adult tickets, 375 student tickets
Step-by-step explanation:
a = adult tickets
s = student tickets
a + s = 600 (the adult and student ticket added together should equal 600)
6.00a + 4.50s = 3,037.50 ($6 multiply by the adult ticket plus $4.50 multiply by the student ticket should equal to 3,037.50)
a = -s + 600 (get one of the variable by itself by subtracting it from one side)
6 (-s + 600) + 4.5s = 3,037.5 (substitute the a for -s + 600)
-6s + 3600 + 4.5s = 3,037.5 (combine like terms)
-1.5s + 3600 = 3,037.5 (subtract 3600 from each side)
-1.5s = - 562.5 (divide -1.5 from each side)
s = 375
600 = 375 + a (substitute s for 375)
a = 225

Marla bought 1250 pounds of pecans at $1.29 per pound and another 1500 pounds of pecans at $1.59 per pound. She sold all the pecans for \$6.75 per kilogram. After paying her suppliers, how much money did she make?
Answer:
After paying her suppliers, she made $4,575.
Step-by-step explanation:
First, you have to multiply the number of pounds purchased for the price:
$1.29*1250=$1,612.5
$1.50*1500=$2,250
Now, you can add both amounts to find the total cost:
$1,612.5+$2,250=$3,862.5
Now, you have to find the total amount of lb purchased and determine the kg they represent given that 1 kg is equal to 2.20 lb:
1250+1500=2750
2.20 lb → 1 kg
2750 lb → x
x=(2750*1)/2.20= 1250 kg
Now, you can find the total amount sold by multiplying the price per kilogram for the amount of kg:
$6.75*1250=$8,437.5
Finally, you have to subtract the total cost from the total amount sold:
$8,437.5-$3,862.5=$4,575
According to this, the answer is that after paying her suppliers, she made $4,575.

Will mark brailest if you are right!!!
Answer:
f(x) = 3x
Step-by-step explanation:
The equation of a line passing through the origin is
y = mx ( m is the slope )
Calculate m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (0, 0) and (x₂, y₂ ) = (1, 3)
m = [tex]\frac{3-0}{1-0}[/tex] = 3 , then
y = 3x ← is the equation of the graphed line
what is 11^0 x 5x - 789
X=6
Answer:
-759
Step-by-step explanation:
Any number powered by 0 equals to 1, so the equation then becomes 1 × 5x - 789, but then x is 6, so it's 30 - 789, which is -759.

The sum of four consecutive integers is -26. What are the integers? A book has pases.
Answer:
In the same manner, the third integer can be represented as n + 2 {n + 2} n+2 and the fourth integer as n + 3 {n + 3} n+3. We can then translate “the sum of four consecutive integers is 238” into an equation.
