Use the distributive property to write an equivalent expression of the following
2 ( b + c )
5 (7h + 3m)
4 (x+y)
c ( 3a + b )
Answer:
2b+2c
35h+15m
4x+4y
3ac+bc
Answer:
Solution given:
2 ( b + c )=2b+2c
5 (7h + 3m)=35h+15m
4 (x+y)=4x+4y
c ( 3a + b )=3ac+bc

Evaluate the following linear expression. -4(x-6)-30
A.
-4x-6
B.
-4x+6
C.
-4x+54
D.
-4x-3
Answer:-4x-6
Step-by-step explanation:
Answer:
A.
Step-by-step explanation:
Multiply -4 to x and -6. After that you get -4x + 24 - 30. Then, subtract 24 by 60, to get -6. You should be left with -4x - 6.
How do I solve equations with a variable to the power of something (give steps please)
Like these.
[tex]2x^2+5x=0[/tex]
Answer:
Step-by-step explanation:
Factoring will reveal the solution. So we divide the equation by the greatest common factor of the terms and use that factor as the coefficient. In this case the greatest common factor is just x.
2x^2+5x
x(2x+5) so the equation will equal zero when either of those expressions is zero because zero times anything is zero. x=0 and x=-5/2
Answer:
[tex]x = 0, -\frac{5}{2}[/tex]
Step-by-step explanation:
First move all terms to one side of the equation to set them equal to 0
That is already done in your problem
The try to factor, if possible. In your case, factor out x
x(2x + 5) = 0 Now, use the property that says if AB = 0, then A = 0 or B = 0 or both A and B equal 0
So, x = 0 or 2x + 5 = 0
2x = -5
x = [tex]-\frac{5}{2}[/tex]
Always check your results in the original equation to see if they work
[tex]2(0^{2} + 5(0) = 0 + 0 = 0\\[/tex]
and [tex]2(-\frac{5}{2} )^{2} + 5(-\frac{5}{2} )\\ = 2(\frac{25}{4} ) - \frac{25}{2} \\ = \frac{25}{2} - \frac{25}{2} = 0[/tex]
Both results make the equation true, so [tex]x = 0, -\frac{5}{2}[/tex]
Determine the length of the longest piece of timber which could be stored in a rectangular shed 6cm by 5cm by 2m high
Answer:
6 90u7 jhi
Step-by-step explanation:
Answer:
200.2
Step-by-step explanation:
I would hate to own such a shed. It's not very big.
2 meters = 2 * 100 cm = 200 cm
The diagonal of the floor is the diagonal of 6cm by 5cm. Using a^2 + b^2 = c^2
5^2 + 6^2 = 25 + 36 = 61
The square root of 61 is 7.81 cm
Now the diagonal of the floor diagonal and the height
a^2 + h^2 = board^2
61 + 200^2 = board^2
61 + 40000 = board^2
40061 = board^2
sqrt(board^2) = sqrt(40061)
board = 200.2cm long.
Maybe you should check the question for units.

Answer:
y=x+10
Step-by-step explanation:
it's a guess. it goes up 1 over 1 so the "m" in y=mx+b has to be 1. so x stands alone. the line looks like it begins at 10 so the b will equal 10
Answer:
y = 5x + 10
Step-by-step explanation:
Line is passing through the points (2, 20) & (4, 30)
Slope of line (m) = (30 - 20)/ (4 - 2) = 10/2 = 5
y - 20 = 5(x - 2)
y = 5x - 10 + 20
y = 5x + 10

Answer:
The equation is:
y = -15*x + 1200
and:
a = 120
b = 70
c = -1500
Step-by-step explanation:
This seems to be a linear relationship.
A linear relationship can be written as:
y = a*x + b
where a is the slope and b is the y-axis intercept.
For a line that passes through the points (x1, y1) and (x2, y2), the slope can be written as:
a = (y2 - y1)/(x2 - x1).
Here we know that our line passes through the points (60, 300) and (20, 900)
Then the slope of this line is:
a = (900 - 300)/(20 - 60) = 600/(-40) = -15
Then this line is something like:
y = -15*x + b
To find the value of b, we know that this line passes through the point (60, 300) then when x = 60, we have y = 300.
Replacing these values in the above equation we get:
300 = -15*60 + b
300 + 15*60 = b = 1200
Then:
y = -15*x + 1200.
Now that we have this equation, we can complete the table.
a is the value for y, when x = 72
Then we can replace x by 72 in the above equation:
a = -15*72 + 1200 = 120
a = 120
b is the value of x when y = 150, then we need to replace y by 150
150 = -15*b + 1200
150 - 1200 = -15*b
(150 - 1200)/-15 = b = 70
then:
b = 70
c is the value of y when x = 180, then we need to replace x by 180.
c = -15*180 + 1200
c = -1500
What is the value of y in the equation y = 3 x − 2 , y = 3 x − 2 , given that x = 5 ?

Answer:
He would collect 28 cans
Step-by-step explanation:
Ethan = 1/3
84 * 1/3 = 28
Answer:
28 cans were collected by Ethan
Step-by-step explanation:
It says that the total amount of cans collected was 84 cans. Of the 84 total cans, Ethan collected 1/3 of them. To find the number of cans Ethan collected, you would multiply 84 • 1/3. (You could also divide 84 by 3 in this case)
84 • 1/3 = 28

find the value of x please help
using angle sum property
we get
110+35+(x+12)=180
(x+12)=180-145
(x+12)= 35
x= 35-12
x= 23
Answer:
Angles in a triangle are sum up to 180 degrees.
35 + 110 + (x+12)=180
145+x+12=180
157+x=180
x=180-157
