Answer:
[tex]x=2y+3[/tex]
Step-by-step explanation:
So we have the equation:
[tex]x-2y=3[/tex]
And we want to solve for x. In other words, we want to isolate the x-variable.
So, add 2y to both sides of the equation.
[tex](x-2y)+2y=(3)+2y[/tex]
On the left, the 2y cancel. Simplify the right:
[tex]x=2y+3[/tex]
And we're done!
Answer:
x = 3 + 2y
Step-by-step explanation:
This is the answer because:
1) First, you have to isolate x, in order to isolate x you have to bring x to the end of the equation.
2) Then, you have to add 2y to both sides of the equation.
Another way you can think of this is:
1) If you add 3 + 2y you would figure out the answer because if you want to find x for a subtraction equation, you can add the answer to the equation with the number.
For example, x - 20 = 10, now to figure this equation out, you can either isolate the x, or you can add the answer in the equation with the remaining number in the equation.
Hope this helps!

I Need All Three , please show work !
Answer:
1) d=25 2) d=2[tex]\sqrt{2}[/tex] 3) d=[tex]13\sqrt{2}[/tex]
Step-by-step explanation:
[tex]d=\sqrt{(-2-1)^2+(-2-2)^2}\\ d=\sqrt{(-3)^2+(-4)^2} \\d=\sqrt{(-9)+(-16)}\\d=\sqrt{-25} \\d=5[/tex]
[tex]d=\sqrt{(5-3)^2+(-4-(-6))^2}\\ d=\sqrt{(2)^2+(2)^2} \\d=\sqrt{(4)+(4)}\\d=\sqrt{8} \\d=2\sqrt{2}[/tex]
[tex]d=\sqrt{(8-(-9))^2+(-7-0)^2}\\ d=\sqrt{(17)^2+(-7)^2} \\d=\sqrt{(289)+(49)}\\d=\sqrt{338} \\d=13\sqrt{2}[/tex]

Is 39,052 divisible by 3?
Answer:
no as the answer would be a decimal
Step-by-step explanation:
an easier way to know is to add up all the digits
3 + 9+0 +5+2= 19 and if that number is a multiple of 3 then it will be divisible by 3
this works for any number that should be divided by 3
example
is 2345 divisible by 3
2+3+4+5 =14 so no it is not divisible by 3
example
is 12345 divisible by 3
1+2+3+4+5 =15 so yes it is divisible by 3
hope this helps
pls can u help me with my most recent question pls and thx
Steve Fossett completed the first solo balloon circumnavigation of the world after 13.5 days. Assuming the balloon travelled along a circle of diameter 12 750 km, roughly what was the average speed of the balloon in km/h?
A) 12
B) 40
C) 75
D) 120
E) 300
Answer:
B) 40
Step-by-step explanation:
Average speed = distance/time
Distance = 12750 km
Time = 13.5 days = 13.5*24 hours = 324 hours
Speed = 12750 km /324 h = 39.4 km/h ≈ 40 km/h
Correct option is B) 40

Onestion 7
2 nits
Y
Answer:
Between $59.50 and $61.50
Step-by-step explanation:
Since this is about, we have to round the numbers.
85.58 is rounded to 86
24.98 is rounded to 25
2.49 is rounded to 2.50
Therefore:
86 - 25 - 2.50 = 59.50
So the correct answer is #3

A store buys bananas by weight. The total cost to buy 5 pounds of bananas is $ 3.75. Which choice shows how to correctly calculate the total cost T to buy 2 pounds of bananans
Answer
5=$3.75
3.75÷5=.75 ($.75 per banana)
.75x2=T
T=$1.50
Step-by-step explanation:
Answer:
T = 0.75(2)
Step-by-step explanation:
$3.75 ÷ 5 = 0.75
0.75 x 2 = 1.5
T = 0.75(2)
Find the measure of an angle if its measure is 26 degrees more than three times its compliment?
16
141
74
42
The complement = x
The angle we are finding = 3x + 26
Complementary angles are angles that add up to 90 degrees.
90 = x + 3x + 26
Combine like terms
90 = 4x + 26
Subtract 26 from both sides
64 = 4x
Divide both sides by 4
16 = x
The angle we are trying to find = 3(16) + 26 = 48 + 26 = 74 degrees

B is between A and C. If AB = 7x - 2, BC = 3x + 1 and AC = 59, Find AB
Answer:
AB = 40Step-by-step explanation:
B is between A and C so:
AB + BC = AC
7x - 2 + 3x + 1 = 59
10x - 1 = 59
+1 +1
10x = 60
÷10 ÷10
x = 6
AB = 7x - 2 = 7×6 - 2 = 42 - 2 = 40

Explain how to simplify the expression -98 - 31? Using the additive inverse.
Given:
The expression is -98 - 31.
To find:
The value of the given expression using the additive inverse.
Solution:
According to the additive inverse, for any number a,
[tex]a+(-a)=0[/tex]
Using additive inverse, we have
[tex]98+(-98)=0[/tex] ...(i)
[tex]31+(-31)=0[/tex] ...(ii)
Now, using (i) and (ii), we get
[tex]98+(-98)+31+(-31)=0[/tex]
[tex](98+31)+(-98-31)=0[/tex]
[tex]129+(-98-31)=0[/tex]
Subtracting 129 from both sides, we get
[tex]-98-31=-129[/tex]
Therefore, the value of given expression is -129.
