Step-by-step explanation:
Simplifying
(8x + 9) + -1(6x + -1) = 0
Reorder the terms:
(9 + 8x) + -1(6x + -1) = 0
Remove parenthesis around (9 + 8x)
9 + 8x + -1(6x + -1) = 0
Reorder the terms:
9 + 8x + -1(-1 + 6x) = 0
9 + 8x + (-1 * -1 + 6x * -1) = 0
9 + 8x + (1 + -6x) = 0
Reorder the terms:
9 + 1 + 8x + -6x = 0
Combine like terms: 9 + 1 = 10
10 + 8x + -6x = 0
Combine like terms: 8x + -6x = 2x
10 + 2x = 0
Solving
10 + 2x = 0
Solving for variable 'x'.
Move all terms containing x to the left, all other terms to the right.
Add '-10' to each side of the equation.
10 + -10 + 2x = 0 + -10
Combine like terms: 10 + -10 = 0
0 + 2x = 0 + -10
2x = 0 + -10
Combine like terms: 0 + -10 = -10
2x = -10
Divide each side by '2'.
x = -5
Simplifying
x = -5

Han drinks three gallons of iced tea each day. Each gallon of iced tea contains ¾ cups of sugar. How much sugar does Han drink when drinking her iced tea each day?
Answer:
3 cups of sugar.
Step-by-step explanation:
Han drinks 3/4 of a cup of sugar each day when she drinks iced tea. She drinks 3 gallons, and each contains 3/4. If each contains only 3/4, we will have to multiply 3/4 by 3 gallons to find our answer to this question.
[tex]\frac{3}{4} = 1 \text{-gallon}[/tex]
So, now we will have to multiply 3/4 by the number 3.
[tex]\frac{3}{4}[/tex] × [tex]3[/tex] = [tex]\frac{12}{4}[/tex]
12/4 is equal to 3, so the answer is 3.
A closed rectangular tank measures 5 meters by 10 meters by 6 meters. What is the surface area of the tank?
Answer:
280 square units
Step-by-step explanation:
Using the given dimensions {5, 6, 10}, find the area of the front, top and end of the box: 5*6 + 5*10 + 6*10 = 140 square units.
The back of the box is the same size and shape as the front, the bottom the same as the top, and the other end the same as the first end. Thus, multiply 140 square units by 2 to get the total surface area of the tank:
It is 280 square units.

Si debes tomar 0.035 litros de agua por cada kg de peso al día, si pesaras 50 kg ¿Cuánta agua deberás beber en un día? ayuda porfavor
Answer:
Deberás beber 1.75 litros de agua en un día.
Step-by-step explanation:
De acuerdo a la información dada, puedes utilizar una regla de tres para encontrar la cantidad de agua que deberás beber en un día si pesas 50 kg dado que debes tomar 0.035 litros por cada kg:
1kg → 0.035 litros
50 kg → x
x=(50*0.035)/1=1.75 litros
De acuerdo a esto, la respuesta es que deberás beber 1.75 litros de agua en un día.
