Answer:
Question 6: I know that (8 + 9) + 3 is equal to 8 + (9 + 3) because of the associative property states that you can change the grouping of addends in any order you want. The benefit to using this property is that you can first add numbers that you can combine more easily. For example, (743 + 51) + 49 can be written as 743 + (51 + 49) or 743 + 100. It is more straightforward to add the numbers that equal 100 first and then add the final number.
Question 3: -3(4x + 3) + 5x [Given]; -12x - 9 + 5x [Distributive Property]; -12x + 5x - 9 [Commutative Property]; -7x - 9 [Combine like-terms]. [tex]\frac{1}{2}[/tex] (6k + 10) + 5k [Given]; 3k + 5 + 5k [Distributive Property]; 3k + 5k + 5 [Commutative Property]; 8k + 5 [ Combine like-terms].
Question 4: 4(2 - 5) - 8 = 4 * (-3) - 8 = -12 - 8 = -20; 4 * 2 - 28 = 8 - 28 = -20.
Question 5: 15 * 3 - 2(2 * 3 + 6) = 45 - 2(6 + 6) = 45 - 2(12) = 45 - 24 = 21; 11 * 3 - 12 = 33 - 12 = 21.
se quiere pintar una pared en forma de hexágono regular y se sabe que cada lado mide 3m y que su apotema es de 2,8m cual es el area que se va a pintar?
Answer:
El área total a pintar será:
[tex]A_{tot}=25.2\: m^{2}[/tex]
Step-by-step explanation:
Sabiendo el apotema y la longitu de los lados, podemos encontrar el área de un triangulo. Recordemos que, si trazamos rectas del centro del hexágono a los vértices, se formaran 6 triángulos equiláteros.
El área de un triángulo es:
[tex]A_{t1}=\frac{b*a}{2}[/tex]
b es la longitud de la base (b=3 m)
a es la apotema, osea la altura del triangulo (a = 2.8)
[tex]A_{t1}=\frac{2.8*3}{2}[/tex]
[tex]A_{t1}=4.2\: m^{2}[/tex]
Ahora, solo debemos mutiplicar ese valor por 6 para determianr el área total de la pared.
[tex]A_{tot}=25.2\: m^{2}[/tex]
Espero te haya sido util!

Please help!!! Have been stuck on this problem for the past hour. can someone be so kind and explain it to me. I have a Quiz tomorrow on this. solving systems using substitution y = - 7y + 3; Y+ 7x = 10
Answer:
Step-by-step explanation:
y = -7x+3
substitute -7x+3 for y in the other equation.
y + 7x = 10
(-7x+3) + 7x = 10
3 = 10, a contradiction, so there is no solution.
If you were to graph both equations, you would see that they are parallel lines. There is no point that belongs to both lines, so there is no (x,y) that satisfies both equations.
8. what is the volume of these 5 objects
Answer:
1) B
Step-by-step explanation:
To get the volume of a cube, you multiply the length, width and height together. 4 x 7 x 8 = 224. 8 × 5 × 6 = 240. This means that chocolate box B has the larger volume.
Let the amount of money Tabitha started with be represented by x.
Tabitha then earned $52, spent $40,earned $28, and spent $58.How
much money, in terms of x, does Tabitha have now?
If Tabitha started with $50, then she would have $38 left.
Step-by-step explanation:
50 + 52 = 102.
102 - 40 = 62.
62 + 28 = 90.
90 - 58 = 38.
Answer:
38

Use the tangent to find the length of side PR.Express your answer to the nearest tenth.
Answer:
PR = 4.9
Step-by-step explanation:
For given angle Q, RQ is the adjacent leg, and PR is the opposite leg.
We recall the meaning of the tangent ratio.
tan A = opp/adj
Here we have
tan Q = opp/adj
tan 51 deg = PR/4.0
PR = 4.0 * tan 51 deg = 4.9
Answer: PR = 4.9

Cranberry juice is made with a 16:3:1 ratio of water:sugar:cranberries. How much water,
in gallons, how much water is needed in order to make three gallons of cranberry juice? Express your answer as a
common fraction.
Answer:
2 2/5
Step-by-step explanation:
We need to find out how many gallons of water so,
16/20 = water
3 gallons * 16/20 = 48/20 = 2 8/20 = 2 2/5
this works because then cranberries would be:
2 2/5/16 = 15/100
and for sugar that means
15/100 * 3 = 45/100
so in total
2 40/100 + 45/100 + 15/100 = 3 gallons
and if we simpilfy 2 40/200 we get 2 2/5
equations with variables on both sides that makes the answer x=9

What is 1/7 divided by -2 and 2/3
Answer:
Step-by-step explanation:
1/7 divided by -2 2/3
= 1/7 divided by -8/3 (changed the mixed number to an improper fraction!)
= 1/7 MULTIPLIED by -3/8 (when you divide a fraction, you must switch the sign opposite to what you are doing, in this case dividing, so the opposite of that is multiplying. You also flip the fraction that you are dividing by so -8/3 becomes -3/8)
= -3/56 (a positive times a negative number will result in a negative number!)

Shani has 2 chocolate bas. One has 60% cacao and the other 92% calco
What mass of each bar must she mix to obtain 400g of chocolate
with 72% cacao
Answer:
250 grams of the 60% cocoa bar and 150 grams of the 92% cocoa bar should be used.
Step-by-step explanation:
Given that Shani has 2 chocolate bars, one that had 60% cocoa and the other that had 92% cocoa, to determine what mass of each bar must she mix to obtain 400g of chocolate with 72% cocoa, the following calculation must be performed:
100 x 0.6 + 0 x 0.92 = 60
90 x 0.6 + 10 x 0.92 = 63.2
80 x 0.6 + 20 x 0.92 = 66.4
70 x 0.6 + 30 x 0.92 = 69.6
65 x 0.6 + 35 x 0.92 = 71.2
63 x 0.6 + 37 x 0.92 = 71.84
62.5 x 0.6 + 37.5 x 0.92 = 72
400 x 0.625 = 250
Thus, 250 grams of the 60% cocoa bar and 150 grams of the 92% cocoa bar should be used.
Given that 7x – 4y = 6
Find x when y=9
Answer:
6
Step-by-step explanation:
Substitute y for 9: 7x - 36 = 6
Add 36 to both sides: 7x = 42
Divide both sides by 7: x = 6

In which step did Viet make an error?
Answer:
Step 1
Step-by-step explanation:
When moving the 4 to the other side, Viet was supposed to subtract 4 from each side, leaving 0 on the left, and 102-4 on the other side. 102-4=98, not 106. Viet added when he was supposed to subtract.
what is the solution to 5(4x-1.5x)+12-2
Answer:
12.5x+10
Step-by-step explanation:
I'm assuming that you want to simplify this, because there is no equal sign.
If you want to simplify, first combine like terms.
First solve the first half of the equation: 20x-7.5x=12.5x
Now solve the second half of the equation: 12-2=10, so we have 12.5x+10.
That's your answer: 12.5x+10
Answer:
x = 0.8
Step-by-step explanation:
Your equation is 5(4x - 1.5x) + 12 - 2. Simply, you have to solve for x.
First, you have to do distributive property. 5 x 4 and -1.5 (1.5 is negative as I plus-minus.) This will now lead you to have the equation 20x + -7.5x + 12 - 2.
Next, you subtract 12 - 2. Then add 20x + -7.5x. Your equation should be 12.5x = 10.
Since you want x by itself, you will divide all by 12.5 in which 10 divided by 12.5 is 0.8. So your final answer is
x = 0.8

we know that the equation on the line is given by y equals MX plus b, where M & B are numbers it's is its slope and b is it's y - intercept.
in order to find the equation we must find m and b.
we are going to use two points where the line crosses, in the figure we can see that it crosses points
(0, 4) and (2,1).
