Answer:
a = - c
Step-by-step explanation:
2a - 2c = 4a
- 4a - 4a
- 2a - 2c = 0
+ 2c + 2c
- 2a = 2c
/-2 /-2
a = - c
Answer:
[tex]\boxed {a = -c}[/tex]
Step-by-step explanation:
Solve for the value of [tex]a[/tex]:
[tex]2a - 2c = 4a[/tex]
-Take [tex]4a[/tex] and subtract it from [tex]2a[/tex]:
[tex]2a - 2c - 4a = 4a - 4a[/tex]
[tex]-2a - 2c = 0[/tex]
-Add both sides by [tex]2c[/tex]:
[tex]-2a - 2c + 2c = + 2c[/tex]
[tex]-2a = 2c[/tex]
-Divide both sides by [tex]-2[/tex] and dividing [tex]-2[/tex] undoes the multiplication by [tex]-2[/tex]:
[tex]\frac{-2a}{-2} = \frac{-2c}{-2}[/tex]
[tex]\boxed {a = -c}[/tex]
Therefore, the value of [tex]a[/tex] is [tex]-c[/tex].

Step-by-step explanation:
An object is traveling at a steady speed of 10 1/10 km/h. How long will it take the object to travel 1 9/10 km?
Answer:
It will take [tex]\frac{19}{101}[/tex] hour.
Step-by-step explanation:
The rule of the distance is:
Distance = speed × time
∵ An object is traveling at a steady speed of [tex]10\frac{1}{10}[/tex] km/h
∴ The speed = [tex]10\frac{1}{10}[/tex] km/h
∵ The object will travel [tex]1\frac{9}{10}[/tex] km
∴ The distance = [tex]1\frac{9}{10}[/tex] km
→ We need to find how long will it take it to travel this distance
→ Substitute the values of distance and speed in the rule above
∵ [tex]1\frac{9}{10}[/tex] = [tex]10\frac{1}{10}[/tex] × time
→ To find the time divide both sides by [tex]10\frac{1}{10}[/tex]
∴ The time = [tex]1\frac{9}{10}[/tex] ÷ [tex]10\frac{1}{10}[/tex]
→ Change the mixed numbers to an improper fraction
∵ [tex]1\frac{9}{10}[/tex] = [tex]\frac{(1)(10)+9}{10}=\frac{19}{10}[/tex]
∵ [tex]10\frac{1}{10}=\frac{(10)(10)+1}{10}=\frac{101}{10}[/tex]
∴ The time = [tex]\frac{19}{10}[/tex] ÷ [tex]\frac{101}{10}[/tex]
- Reverse the fraction after the division sign, then change ÷ to ×
∴ The time = [tex]\frac{19}{10}[/tex] × [tex]\frac{10}{101}[/tex]
→ 10 up will cancel 10 down
∴ The time = [tex]\frac{19}{101}[/tex] h
It will take [tex]\frac{19}{101}[/tex] hour.
KL = 2x + 2
JL = 55, and
JK = 7* +8,
Find KL.
J
K
L
Answer:
KL = 12Step-by-step explanation:
JK + KL = JL
where:
JK = 7x + 8
KL = 2x + 2
JL = 55
plugin values into the equation:
7x + 8 + 2x + 2 = 55
7x + 2x = 55 - 8 - 2
9x = 45
x = 45 / 9
x = 5
KL = 2x + 2
KL = 2(5) + 2
KL = 12
A group of 3 friends were going on a hike. One friend brought 0.75 lbs of trail mix, the second friend brought 1.3 lbs of trail mix, and the third friend brought 0.35 lbs of trail mix. If they combine all their trail mix and split it equally among the 3 friends, how much trail mix does each friend get?
lbs
Answer:
0.8 pounds
Step-by-step explanation:
0.75 plus 1.3 plus 0.35 = 2.40 pounds
2.40 divided by 3 is 0.8 pounds

i need help!! please help me!
Answer:
first table, the answer is -1
f(x)=x always rmmbr that so f(3)=-1 bcoz of the value 3 which represents the Term.
in second table, the values are at a 12 difference.
23-12=11, 11-12=-1,-1-12=-13, so -13-12=-25 and so on
second option is correct.
hope you understood best of luck

Answer:
- 2.25/3
Step-by-step explanation:
5 2/3 gave to her 4 friends how much did each one receive
Answer:
Let's see what to do buddy...
Step-by-step explanation:
If it is 5 + 2/3
_________________________________
Step (1)
First we have to find all she has :
[tex]5 \frac{2}{3} = 5 + \frac{2}{3} = \frac{5 \times 3}{3} + \frac{2}{3} = \\ \frac{15}{3} + \frac{2}{3} = \frac{17}{3} [/tex]
_________________________________
Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :
[tex] \frac{17}{3} \div 4 = \frac{17}{3} \times \frac{1}{4} = \frac{17}{12} \\ [/tex]
So each of her friends receive 17/12 .
_________________________________
_________________________________
_________________________________
If it is 5 × 2/3
_________________________________
Step (1)
Firs we have to find all she has :
[tex]5 \times \frac{2}{3} = \frac{10}{3} \\ [/tex]
_________________________________
Step (2)
To find how much did each of them receive , we must divided all by the number of her friends which is 4.
So we have :
[tex] \frac{10}{3} \div 4 = \frac{10}{3} \times \frac{1}{4} = \frac{10}{12} \\ [/tex]
So each of her friends receive 10/12 .
_________________________________
And we're done.
Thanks for watching buddy good luck.

What are the solutions to f(x) = g(x)?
x = 0 and x = 1
x = -2 and x = 5
x = 0 and x = -3
x = 10 and x = -8
Answer:
x = 0 and x = 1
Step-by-step explanation:
From the table of values
f(x) = g(x) = 1 when x = 0 , and
f(x) = g(x) = 0.25 when x = 1
The solution to f(x) = g(x) are x = 0 and x = 1

2. there are two phone plans. One plan a $28 monthly fee, and cost 9 cents per minute. The second plan is 13 cents per minute, and $ 30 monthly fee.
A. Write and equations to represent the number of minutes use in a month that will make the plans cost the same?
B. Solbe the equation to find the number of minutes
_________________________________________________________________
3. cell phone plan costs per month for unlimited calling plus $0.15 per text message.
A. write a linear model that represents the monthly cost of this cell phone plan if the user sends t text messages
b. if you send 200 text messages, how much would you pay according to this cell phone plan?
Answer:
for the first one the answer is 28-9=18 and 30-13=17 are not the same but are close and for the second one the answer is $30 for the phone plan cause 200×0.15=30
If you use 50 minutes in a month, both plans will cost $32.50.
What is the equation?The equation is defined as mathematical statements that have a minimum of two terms containing variables or numbers that are equal.
2.
A. Let x be the number of minutes used in a month. Then, the cost of Plan A is given by:
Cost(A) = 0.09x + 28
The cost of Plan B is given by:
Cost(B) = 0.13x + 30
To find the number of minutes that will make the plans cost the same, we need to set Cost(A) equal to Cost(B) and solve for x:
0.09x + 28 = 0.13x + 30
0.04x = 2
x = 50
Therefore, the plans will cost the same if you use 50 minutes in a month.
B. If you use 50 minutes in a month, the cost of Plan A will be:
Cost(A) = 0.09(50) + 28 = 32.50
The cost of Plan B will also be:
Cost(B) = 0.13(50) + 30 = 36.50
Therefore, if you use 50 minutes in a month, both plans will cost $32.50.
3.
A. Let C be the monthly cost and t be the number of text messages sent. Then, the linear model that represents the monthly cost is:
C = 0.15t + base cost
The base cost is the cost for unlimited calling, which is not specified in the problem.
B. If you send 200 text messages, the monthly cost will be:
C = 0.15(200) + base cost
C = 30 + base cost
The total cost will depend on the base cost for unlimited calling.

You start driving from Austin to Houston with a constant speed of 120km/hr (75 mph). After 1.5 hr you stop for 0.5 hr. Then you continue driving with a new constant speed v2 and reach Houston 45 mins later. If the total distance from Austin to Houston is 265km, what is the speed v2?
Answer:
113.33 km/hr
Step-by-step explanation:
Given that :
From Austin
Drive 1 : Speed of 120km/hr for 1.5 hours
Stop time = 0.5 hour
Drive 2 : speed of v2 for 45 minutes to finally reach Houston
Total distance (Austin to Houston) = 265 km
Total distance : (distance on drive + distance on second drive)
Distance = speed * time
(120 * 1.5) + (v2 * 45/60) = 265
180 + 0.75v2 = 265
0.75v2 = 265 - 180
0.75v2 = 85
v2 = 85 / 0.75
v2 = 113.33km/hr
v2 = 85 / 0.75
v2 =

The length of a rectangle is (x-8) units, and its width is(x+11) units. What is an expression for this.
Answer:
(x²+3x-88) square units
Step-by-step explanation:
Area of a rectangle = Length × Width
Given
length of a rectangle is (x-8)units
Its width is (x+11) units.
Required
Expression for the area of the rectangle
Substituting the given function into the formula.
Area of the rectangle = (x-8)(x+11)
Area of the rectangle = x(x)+11x-8x-88
Area of the rectangle = x²+3x-88
Hence the expression that represents the area of the rectangle is x²+3x-88 units²
