6.4n + 10= 4.4n - 6
Could you help? Thanks
Answers
Answer:
n=-8
Step-by-step explanation:
6.4n + 10= 4.4n -6
Subtract 4.4n on both sides
You then have 2n+10=-6
Subtract 10 on both sides You then have 2n=-16
Divide both sides by 2
n= -8
Hoped that helped
Answer: n= -8
Step-by-step explanation:
Get all the n's on one side, all the regular numbers on the other
Add or subtract from both sides
6.4n -4.4n +10 = 4.4n -4.4n -6 So 4.4n -4.4n = 0, "cancels' on right
2.0n +10 -10 = -6 -10 10's cancel on the left. -6-10 .=-16 on right
2n = -16 (.0 is not needed in 2.0) Divide both sides by 2
n = -8

Step-by-step explanation:
Find the value of x.
[tex]2x + 50 = x + 76 \\ 2x - x = 76 - 50 \\ x = 26[/tex]
Substitute x to the equation for angle 2.
[tex]2x + 50 \\ = 2(26) + 50 \\ = 52 + 50 \\ = 102[/tex]
#CarryOnLearning
Answer:
A) 102
Step-by-step explanation:
Alternative Exterior Theorem: If two parallel lines are cut by a transversal, then the pairs of alternative exterior angles are congruent.
Because of this theorem, we know that <2 and <8 are congruent, so we can set these equations to be equal to each other, like so:
2x + 50 = x + 76
Then, we need to find the x value, so solve from there.
2x + 50 = x + 76
x + 50 = 76 [Subtract x from both sides of the equal sign]
x = 26 [Subtract 50 from both sides of the equal sign]
So now that we have our x value, all we have to do is plug in that value to the <2 equation.
2x + 50
2(26) + 50
52 + 50
102

15%Step-by-step explanation:
this week sold = $2,760
last week sold = $2,400
the difference from this week to last week = 2700-2400 = 360
that means it increased : 360 / 2400 = 0.15 (100%) = 15%
therefore, the increase of sale is 15%

Answers
Answer:
1) 102
2) 62
Step-by-step explanation:
12 + 5 + 3² × 10 - 5
12 + 5 + 9 × 10 - 5
12 + 5 + 90 - 5
17 + 90 - 5
107 - 5
102
(12+5) + 3² × (10 - 5)
(17) + 9 × (5)
17 + 45
62
12 + 5 + 3^2 x 10 - 5 = 102
(12 + 5)+ 3^2 x (10 - 5) = 62
12 + 5 + 3^2 x 10 - 5
Add 12 and 5 to get 17
17 + 3^2 × 10−5
Calculate 3 to the power of 2 and get 9
17 + 9 × 10 − 5
Multiply 9 and 10 to get 90
17 + 90 − 5
Add 17 and 90 to get 107
107−5
Subtract 5 from 107 to get 102
(12 + 5)+ 3^2 x (10 - 5)
Add 12 and 5 to get 17
17 + 3^2 x (10 - 5)
Calculate 3 to the power of 2 and get 9
17 + 9 x (10−5)
Subtract 5 from 10 to get 5
17+ 9 × 5
Multiply 9 and 5 to get 45
17+45
Add 17 and 45 to get 62.

Answer:
it actually y=1/3x+17/3
Step-by-step explanation:
First of all, remember what the equation of a line is:
y = mx+b
Where:
m is the slope, and
b is the y-intercept
To start, you know what m is; it's just the slope, which you said was 1/3. So you can right away fill in the equation for a line somewhat to read:
y=1/3x+b.
Now, what about b, the y-intercept?
To find b, think about what your (x,y) point means:
(-2,5). When x of the line is -2, y of the line must be 5.
Because you said the line passes through this point, right?
Now, look at our line's equation so far: . b is what we want, the 1/3 is already set and x and y are just two "free variables" sitting there. We can plug anything we want in for x and y here, but we want the equation for the line that specfically passes through the the point (-2,5).
So, why not plug in for x the number -2 and for y the number 5? This will allow us to solve for b for the particular line that passes through the point you gave!.
(-2,5). y=mx+b or 5=1/3 × -2+b, or solving for b: b=5-(1/3)(-2). b=17/3.
The equation of the line that passes through the point (-2,5) with a slope of 1/3
is
y=1/3x+17/3

x ÷ 4 + 5= 8 I need someone to do it and double check for me please.
Answers
= x/4 + 5 = 8
= x/4 = 8 - 5 ( transposing +5 from LHS to RHS changes +5 to -5 )
= x/4 = 3
= x = 3 × 4 ( transposing ÷4 from LHS to RHS changes ÷4 to ×4 l
= x = 12
Let us see whether the value of x is correct or not by placing 12 in the place of x .
= 12 ÷ 4 + 5 = 8
= 3 + 5 = 8
= 8 = 8
= LHS = RHS
Which means the value of x we found out is correct .
Therefore , x = 12 .Step-by-step explanation:
[tex] \frac{x}{4} + 5 = 8 \\ x + 5 = 32 \ \\ x = 32 - 5 \\ x27[/tex]

What does 13 represent? the answers are- The number of trading cards each friend ended up with The number of trading cards left after each friend got the same amount The number of trading cards left after each friend got 10 The number of friends sharing trading cards
Answers
Answer: The number of trading cards each friend ended up with
Step-by-step explanation:
Given that:
Total Number of trading cards = 79
Number of friends = 6
Number of trading cards each friend got of shared equally :
Total Number of trading cards / number of friends
= 79 / 6
= 13.166
Highest number of cards got by each = 13
Number left : 79 - (13 * 6) = 1
Hence, 13 represents the number of trading cards each friend ended up with
