Answer:
[tex]225[/tex]
Step-by-step explanation:
[tex]\frac{9\cdot \:10^8}{4\cdot \:10^6}=\frac{9\cdot \:10^{8-6}}{4}=\frac{10^2\cdot \:9}{4}[/tex]
[tex]\frac{10^2\cdot \:9}{4}=\frac{2^2\cdot \:5^2\cdot \:9}{2^2}[/tex]
Cancel out common factor:
[tex]5^2\cdot \:9=25\cdot \:9=225[/tex]
Jason bought 3 shirts that each cost the same.He has a coupon for $10 off and he spent $65 altogether.Which equation can be used to find the cost of each shirt? 10s+3+65 3s + 10 =65 3s - 10 = 65 10s -3 =65
Answer:
3s-10=65
Step-by-step explanation:
shirts = 3 s=price
you need to subtract ten because of the cupon
the fine price is 65 so that need to be what the equation equals

If 3 is added to three quarters of a certain number ,the result is 30 .find the original number.
Answer:
X=36
Step-by-step explanation:
Let x be the unknown number
Three quarters of a number =3x/4
Three was added =3x/4 +3
Final
3x/4 + 3= 30
Multiply through with 4
3x+ 12=120
3x=120-12
3x=108
X=108/3
X=36

10 pts The equation y=mx + b goes through the points (6,-2) and (-6, -8). What is the value of m? (-6,-8) What is the value of b?
Answer: m=1/2; b=-5
Step-by-step explanation:
We can use the given points to find slope, then use the y=mx+b equation to find the y-intercept. The formula for slope is [tex]m=\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex].
[tex]m=\frac{-8-(-2)}{-6-6}=\frac{-6}{-12} =\frac{1}{2}[/tex]
Now that we know m=1/2, we can use that in y=mx+b to find the y-intercept. We can use any given point to plug into x and y.
y=1/2x+b [plug in x and y]
-2=1/2(6)+b [multiply]
-2=3+b [subtract both sides by 3]
b=-5
Now, we know that b=-5.

-2(x+3)+5x=-39
please answerrrr
Answer:
x = -11
Step-by-step explanation:
-2(x+3)+5x = -39
distribute the -2 to what's inside the paranthesis
-2x -6 +5x = -39
combine like terms
3x - 6 = -39
add 6 to each side
3x = -33
divide each side by 3
x = -11
Point F is on line segment \overline{EG} EG . Given FG=8,FG=8, EF=2x+4,EF=2x+4, and EG=4x-10,EG=4x−10, determine the numerical length of \overline{EF}. EF .
Answer:
26 units
Step-by-step explanation:
If point F is on the line segment EG, then EF+FG = EG
Given
FG=8,
EF=2x+4
EG=4x−10
Substitute the given values into the formula;
2x+4+8 = 4x−10
2x+12 = 4x-10
collect like terms
2x-4x = -10-12
-2x = -22
x = 22/2
x =11
Since EF = 2x+4
EF = 2(11)+4
EF = 22+4
EF = 26
Hence the numerical length of EF is 26 units
Simplify.

ABC shipping charges $7 plus $1 a pound to ship an overnight package. XYZ shipping charges $10 plus $0.75 a pound to ship an overnight package. For what weight is the charge the same for the two companies?
x = lbs
y = total cost
ABC shipping: $7 + $1x = y
XYZ shipping: $10 + $0.75x = y
We set each equation equal to the other.
$7 + $1x = $10 + $0.75x. Subtract $7 from both sides and subtract $0.75x from both sides
$0.25x = $3. Divide each side by $0.25.
x = 12 lbs
When a package is 12lbs the cost is the same.
