10x - 4 = 16
What does x equal to?
Answer:
x = 2
Step-by-step explanation:
First isolate the variable:
10x - 4 = 16
+4 +4
10x = 20
Then get x by itself:
10x = 20
x = 20/10
x = 10
5+4(8n-8)=-1+6 for n
Answer:
n=1
Step-by-step explanation:
5+4(8n-8)=-1+6
5+32n-32=5
5+32n-32=5
-27+32n=5
32n=32
n=1
Answer:
n = 1
Step-by-step explanation:
5 + 4(8n - 8) = -1 + 6
First you have to distribute the 4 leaving the equation to look like this...
5 + 32n - 32 = -1 + 6
Now solve the constants (normal numbers without a variable)
-27 +32n = 5
+27 +27 You have to add 27 to BOTH sides
32n = 32
n = 1
Hope this helps and have a great day!

Fiften is 30 percent of what number?
Answer:
50
hope it helps
Step-by-step explanation:
Answer:
50
Step-by-step explanation:
The way you solve this is by creating an inequality of
30 15
---- = ----
100 x
So you cross multiply which would give you 30x = 1500, then you divide by 30 on both sides leaving you with 50. If you want to check it, you can then multiply 50 by .30 which would give you 15.

The track star runs 100m at a rate of 10.4m/s. How long did it take to run 100m?
0.1 m/s
9.65
1040m/s
0.1s
Answer:
Time, t = 9.615 secs.
Explanation:
Speed can be defined as distance covered per unit time. Speed is a scalar quantity and as such it has magnitude but no direction.
Mathematically, speed is given by the equation;
[tex]Speed = \frac{distance}{time}[/tex] ....equation 1
[tex]Time = \frac{distance}{speed}[/tex] .....equation 2
Given the following data;
Distance = 100m
Speed = 10.4m/s
Substituting into equation 2;
[tex]Time = \frac{100}{10.4}[/tex]
Time, t = 9.615 secs.

A person is trying to find the height of a flagpole or AB. This person is 1.5 m tall and is
standing at DC. A mirror is placed at point M. This mirror is 6 m away from the person and 120 m away from the flagpole. Angles BMA and DMC are congruent. Find the height of the flagpole or BA.
Answer:
30 m. Your welcome
Step-by-step explanation:
Answer:
30m tall
Step-by-step explanation:
1.5/6 = x/120
Switch sides; cross multiply:
x/120 = 1.5/6
Multiply both sides by 10 and simplify:
x/12 = 5/2
Multiply both side by 12 and get 30m

Okay so, to get C you add the ones inside the triangle together.
42+58=100 Then the last angle will be 80, because when you add the three inside the triangle, you should get 180
42+58+80=180
To get D, you have to subtract 180 and 58, because 58+d will be a straight angle.
180-58=121
To get B and A, you would also have another straight angle (c, b, and a)
180-80=100
I believe that B=A, so, with the remaining 100, both A and B equal 50.
50+50+80=180
Does this help??
Answer:
a° = 58°
b = 42°
c° = 80°
d° = 122°
Step-by-step explanation:
d° can be found because a straight line has an angle of 180°.
180° - 58° = 122°
Because the angles of a triangle add up to 180°, we can find c°
58° + 42° = 100°. 180° - 100° = 80°
You can find a° subtracting 180 and d°, which is 122. 180° - 122° = 58°
You can do the same thing for b°. 180° - 42° = 138°. 180° - 138° = 42°
You can check this because b° + c° + a° should equal 180°.
58° + 42° + 80° = 180°
I hope this helps :)

Answer:
3.5
Step-by-step explanation:
Answer:
0.35( I see that's a lot of help* )
The answer is 0.35 because...
Each row is 10 and there is 3 rows full,
1 row is half full, so that equals 5, and then
you add up all of the numbers and you will get 35.
But, in this case, you need it to be a decimal so you just make it 0.35

A students wants to help her mother in their family store in displaying canned goods. Her mother instructed that the canned should be piled in triangular pile by starting 40 canned goods in the bottom row, 36 in the second row, 32 in the third row, and so on. If the pattern is consistent, how many canned goods will be there in the 7th row?
Answer: The number of canned goods in 7th row = 64.
Step-by-step explanation:
The given numbers of canned goods in every row( starting from first ) is represented as
40 , 36, 32, ...
There is a common difference between numbers(d)= 4
∴ Its is an Arithmetic progression.
First term (a) = 40
nth term in A.P. : [tex]a(n)= a+(n-1)d[/tex]
7th term in this A.P. = 40+(7-1)(4)=40+(6)(4)=40+24=64
So, the number of canned goods in 7th row = 64.
S =4LW + 2WH; S = 96, L= 7, W= 3.
H=
Help please
Answer:
H = 2
Step-by-step explanation:
Order of Operations: BPEMDAS
Step 1: Define
S = 4LW + 2WH
S = 96
L = 7
W = 3
Step 2: Substitute and Evaluate for H
96 = 4(7)(3) + 2(3)H
96 = 84 + 6H
12 = 6H
H = 2
Answer:
H = = 2 H W + 4 L W
Step-by-step explanation:
Substitute the given value into the function and evaluate.
S = 4 L W + 2 W H = = 2 H W + 4 L W
S = 96 = = 2 H W + 4 L W
L = 7 = = 2 H W + 4 L W
W = 3 = = 2 H W + 4 L W
H = = 2 H W + 4 L W
