Answer:
Yes, they are equivalent.
Step-by-step explanation:
To see if they're equivalent, you have to solve them. Start with the first one. Steps are below.Apply the distributed property: 8 + 128 + 12 = 20For second expression:
4(2) = 4 × 2 = 84(3) = 4 × 3 = 12Put them together: 8 + 128 + 12 = 20Making a conclusion:
Because they both have the same answer, they are equivalent expressions.
I hope this helps!
Answer:
40
Step-by-step explanation:
so its simple since the 4(2+3) are in brackets u would put multiply the number in the brakcets for example 2+3 is 5 and that 4 at the side you would multiply it by 4 and you get 20 but then the 4(2) that would just be 4x2 becuase those brackets are singnifieing that its like a multipication problem same with the 4(3) its the same as 4x3 put it all together and you get 40

The gravity coaster travels 340 meters in 10 seconds. The hurricane coater travels 190 meters in 5 seconds. Both coaters travels at a constant. Mario wants to ride the faster roller coaster. How fast does the gravity coaster travel? Find the unit rate.
Answer:
Mario would like to ride Hurricane coaster.
Gravity coaster travels at a unit rate of 34 m/s.
Step-by-step explanation:
Distance traveled by Gravity coaster = 340 meters
Time taken by Gravity coaster = 10 seconds
Distance traveled by Hurricane coaster = 190 meters
Time taken by Hurricane coaster = 5 seconds
Unit rate is nothing but the distance traveled by each coaster in unit time.
To find the unit rate, we can use the following formula:
[tex]Speed = \dfrac{Distance}{Time}[/tex]
Unit rate or speed of Gravity coaster = [tex]\frac{340\ m}{10\ s} = 34\ m/s[/tex]
Unit rate or speed of Hurricane coaster = [tex]\frac{190\ m}{5\ s} = 38\ m/s[/tex]
So, the faster coaster is the Hurricane coaster.
Mario would like to ride Hurricane coaster.
Gravity coaster travels at 34 m/s.

Step-by-step explanation:
the coefficient of the x term is the slope in any equation that is in slope intercept form
Answer:
-3 is the slope
Step-by-step explanation:
The equation is in slope intercept form
y = mx+b where m is the slope and b is the y intercept
y = -3x+7
-3 is the slope and 7 is the y intercept

Find the equation of the line that passes through the following two points: (3, -7) and (7, 2)
Answer:
[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]
Step-by-step explanation:
Slope-intercept form: y = mx + b
Slope formula: [tex]\frac{y2-y1}{x2-x1}[/tex]
Given points: (3, -7), (7, 2)
(3, -7) = (x1, y1)
(7, 2) = (x2, y2)
To write the equation in slope-intercept form, we need to find the slope(m) and the y-intercept(b) of the equation.
First, let's find the slope. To do this, input the given points into the slope formula:
[tex]\frac{2-(-7)}{7-3}[/tex]
Simplify:
2 - (-7) = 2 + 7 = 9
7 - 3 = 4
[tex]\frac{9}{4}[/tex]
The slope is [tex]\frac{9}{4}[/tex].
To find the y-intercept, input the slope and one of the given points(in this example I'll use point (7, 2)) into the equation and solve for b:
[tex]2=\frac{9}{4}(7)+b[/tex]
[tex]2=\frac{63}{4}+b[/tex]
[tex]-\frac{55}{4} =b[/tex]
The y-intercept is [tex]-\frac{55}{4}[/tex].
Now that we know the slope and the y-intercept, we can write the equation:
[tex]y=\frac{9}{4}x-\frac{55}{4}[/tex]

Xavier has a lunch food budget of $120 a month. He spends an average of $6 per day on lunch. Create a table and then a graph to represent the relationship. Then write an equation
where d represents the number of days and m represents that amount of money he had left.
Answer:
m= 120 - 6*d
Step-by-step explanation:
budget is $120 per 1 month, spends $6 per 1 day
on the the table you have 2 columns: one labele it "days" and one "$ spent" and fill it in:
days: 1,2,3,4,..
$ spent: 6, 6*2=12, 6*3= 18, 6*4= 32,...
on the graph lable the horizontal axis "days" and the vertical axis "$ spent"
now plot the points (1,6), (2,12),(3,18), ..., and draw a line trough them
the equation is
m= 120 - 6*d
so after 20 days for example, out of 120 will have m=120-6*20=120-120=0,
$0 wil have in 20 days
1. If energy is the ability to cause change, then
what evidence is there that energy is produced in
the interaction between the wind and the blades of
the wind turbine?
Answer:
We get electricity, that's all the evidence
Step-by-step explanation:
Have a GOOD DAY
We will use the idea that "energy is the ability to cause change" to study the interaction between wind and the blades of a turbine.
This is actually really trivial, if we look at the blades and they are stopped, then we can conclude that there is no wind, thus there is no energy. (By the Newton's laws, we know that there must be a force to change the movement of something).
Now if wind comes, the wind will cause a force on the blades making them rotate.
So a form of energy comes, mechanical energy, and we can see how it produces changes.
Then by the rotation of the blades, there are dynamos that can be used to charge and store energy, this is (roughly) how a wind turbine works.

[tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]
What is Fraction?Fractions represent the parts of a whole or collection of objects.
The given expression is
[tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex]
Firstly we need to convert this mixed fraction to improper fraction.
Improper fractions are fractions whose numerator is greater than denominator.
((15×3)+10)/15 - ((15×1)+12)/15
(45+10)/15 - (15+12)/15
55/15-27/15
15 is the LCM
(55-27)/15
28/15
Now we convert this to improper fraction
[tex]1\frac{13}{15}[/tex]
Hence [tex]1\frac{13}{15}[/tex] is the solution for [tex]3\frac{10}{15}[/tex] - [tex]1\frac{12}{15}[/tex].

∵ In the rhombus, all the sides are equal in length
∵ MNOP is a rhombus
∵ MN = NO = OP = PM
∵ MN = 9x - 77
∵ OP = 3x + 7
→ Equate them to find x
∴ 9x - 77 = 3x + 7
→ Add 77 to both sides
∴ 9x = 3x + 84
→ Subtract 3x from both sides
∴ 6x = 84
→ Divide both sides by 6
∴ x = 14
→ Substitute the value of x in the expression of OP to find its length
∵ OP = 3(14) + 7 = 42 + 7
∴ OP = 49
∵ All the sides are equal in length
∴ MP = 49

∵ The diagonals of the square bisect each other
∵ STUV is a square
∵ SU and TV are its diagonals
∴ W is the mid-point of SU and TV
∴ SW = WU
∵ SW = 2x + 13
∵ WU = 8x - 41
→ Equate them to find x
∴ 8x - 41 = 2x + 13
→ Add 41 to both sides
∴ 8x = 2x + 54
→ Subtract 2x from both sides
∴ 6x = 54
→ Divide both sides by 6
∴ x = 9
→ Substitute x in the expression of SW to find it
∵ SW = 2(9) + 13 = 18 + 13
∴ SW = 31
∵ SU = SW + WU
∵ SW = WU
∴ SU = 31 + 31 = 62
∵ Diagonals of the square are equal in length
∴ SU = VT
∴ VT = 62

Find the total cost to the nearest cent.
$49.95 pair of shoes; 5% tax
Answer:
$52.45
Step-by-step explanation:
the tax is $2.50, if we add that to $49.95 we get $52.45
Total cost will be $52.45.
What is Percentage?
A relative value indicating hundredth part of any quantity is called percentage.
Given that;
Cost of shoes = $49.95
Tax = 5%
Now,
The value of tax = 49.95 × 5%
= 49.95 × 5/100
= 2.50
So, Total cost = $49.95 + $2.50
= $52.45
Thus, Total cost will be $52.45.

The force of gravity on the surface of jupiter is about 2.5 times as strong as that on earth. ON jupiter, the height of a ball dropped from a 100-meter tower is given by the function h(t) = -25t +100 meters at t seconds. How many seconds will it take for the ball to hit the ground?
Answer:
4 seconds
Step-by-step explanation:
Given
[tex]h(t) = -25t + 100[/tex]
Required
Determine what time it hits the ground
When the ball is on the ground, the height is at 0
i.e.
[tex]h(t) = 0[/tex]
Substitute 0 for h(t) in [tex]h(t) = -25t + 100[/tex]
[tex]0 = -25t + 100[/tex]
Collect Like Terms
[tex]25t = 100[/tex]
Solve for t
[tex]t = 100/25[/tex]
[tex]t = 4[/tex]
Hence, the ball will hit the ground in 4 seconds
