Answer:
x = -0.2
Step-by-step explanation:
(5x + 2) = 1
- 2 -2
--------------------
5x = -1
Divide each side by 5
-1/5
= -0.2
Check:
(5x + 2) = 1
replace x with -0.2
(-1 + 2) = 1
1 = 1
The equation is true.
Hope this helped :)

Which expression is equivalent to 4n(6n + 2m)?
A 24n + 4n + 2m
B (4n + 2m) x 6n
C 24n2 + 8mn
D 10n2 + 6mn
Answer:
c maybe
Step-by-step explanation:
4n(6n+2m)
24n²+8mn
Answer: C, 24n²+8mn
Step-by-step explanation:
So because 4n is on the outside of the bracket, you have to times everything on the inside of the bracket by 4n.
So, you do:
4n×6n=24n² (4×6=24 and n×n=n²)
4n×2m=8mn (4×2=8 and n×m=mn)
Then you add 24n² to 8mn like this:
24n²+8mn

Which of the following would be the FIRST step to take when solving the given equation? -11n - 1 = 87
A) Divide both sides of the equation by 11
B) Subtract 11 from both sides of the equation
C) Subtract 1 both sides of the equation
D) Add 1 to both sides of the equation
Answer:
D) Add 1 to both sides of the equation
Step-by-step explanation:
-11n - 1 = 87
-11n = 87 + 1

Answer:
x²+11x+30
Step-by-step explanation:
for this question, all we need to do is multiply (x+5) by (x+6)
we can use the distributive property.
(x+5)(x+6)
x² + 5x + 6x + 30
x² + 11x + 30
student simplifies (6b + 4r) – (2b + r) and says that the result is 4b + 5r. Explain the error and describe the correct steps to simplify the expression.
Answer & explanation:
The student made an error by adding an r after removing the parentheses instead of subtracting an r.
Correct Steps:
(6b + 4r) – (2b + r)
6b + 4r - 2b - r
4b + 3r
Answer:
yo
Step-by-step explanation:
this was the sample response on edge
The student did not distribute the negative when subtracting. Distributing the negative, the expression is equal to 6b + 4r – 2b – r. Then use the commutative property to rewrite it as 6b – 2b + 4r – r. Then you can use the distributive property to write as (6 – 2)b + (4 – 1)r, which simplifies to 4b + 3r.

If a 2ft stick in the ground casts a shadow of 0.8ft, what is the height of a tree that casts a shadow that is 14.24ft?
Answer:
35.6 feets
Step-by-step explanation:
To obtain tree height :
(Height of stick / shadow of stick = height of tree / shadow of tree)
Height of stick = 2 feets
Shadow of stick = 0.8 feets
Shadow of tree = 14.24 feets
Height of tree = h
(2 / 0.8 = h /14.24)
Cross multiply
0.8h = 14.24 * 2
0.8h = 28.48
h = 28.48 / 0.8
h = 35.6 feets

A grain silo is shown below:
Grain silo formed by cylinder with radius 6 feet and height 168 feet and a half sphere on the top
What is the volume of grain that could completely fill this silo, rounded to the nearest whole number? Use 22 over 7 for pi.
Answer: 13750+262=14,012 ft^3
Step-by-step explanation:
Hello!!!
Find the volume of the bottom and top separately and then add them. Cylinder volume is the area of the bottom times the height (22/7)(5^2)•175=13750 ft^3
The volume of a sphere isV=(4/3)(22/7)r^3where r is the radius. also 5 since it fits on the cylinder. Also we only want half the sphere so useV=(2/3)(22/7)•5^3=261.9 ft^3 round upto 262. Now add together 13750+262=14,012 ft^3

What is (-m)⁻³n if m = 2 and n = -24?
Answer:
-3
Step-by-step explanation:
(-2)^-3 x (-24)
(-2)^3 becomes 1/(-2)^3 in order to make the negative exponent a positive one.
then, you do 1/-8 (the -8 is the (-2)^3 simplified) x -24
1/-8 x (24) = 24/-8 = -3.
Hope this helps! :)

Answer:

Step-by-step explanation:
Formula for area A=0.5(bh)
12=0.5(4h)
12=2h
6=h
Answer:
6
Step-by-step explanation:
Area of triangle equation:
A=[tex]\frac{1}{2}[/tex] base * height
For this triangle...
12=[tex]\frac{1}{2}[/tex] (4) (x)
we need to figure out what x is to find the height.
To get x alone in this equation we can first divide both sides by 4
12/4=[tex]\frac{1}{2}[/tex] (x) ---> 3= [tex]\frac{1}{2}[/tex] (x) Then multiply by the reciprocal of 1/2 which is 2/1
x=6
