Answer:
x=8
Step-by-step explanation:
30-5x-10
-5x+30-10
-5x+40
-5x= -40
divide both sides by -5
-5x/-5= -40/-5
x=8

Answer:
C)
Step-by-step explanation:
in order to understand which triangle would lie on the given line we should figure out the slope of the given line first
remember that,
[tex] \displaystyle m = \frac{ y_{2} - y_{1} }{ x_{2} - x_{1}} [/tex]
from the graph let's take two points where the line passes i.e (0,0) and (4,6)
substitute:
[tex] \displaystyle m = \frac{6- 0}{ 4 - 0} [/tex]
simplify substraction:
[tex] \displaystyle m = \frac{6 }{ 4 } [/tex]
reduce fraction:
[tex] \displaystyle m = \frac{3}{ 2} [/tex]
now we need a triangle which tan ratio equal to the slope in that case we can consider the third triangle
[tex] \displaystyle \tan( \theta) = \frac{30}{20} [/tex]
reduce fraction:
[tex] \displaystyle \tan( \theta) = \frac{3}{2} [/tex]
since the tan ratio of the third triangle equal to the slope of the line
hence, our answer is c
Simplify the answer if possible

Step-by-step explanation:
2/3+1/10
Find the LCM (Least Common Multiple):
20/30+3/30 = 23/30
Answer:
A
Step-by-step explanation:
you put 2/3 = 20/30 because you add a 0 2 * 10 is 20 and so on. same for 1/10 multiply nand d by 3= 3/30 so 20/30+3/30= 23/30

Anyways, have an amazing day!
in class slope and y intercept 50 points
Answer:
Slope =-3, y intercept =4
Step-by-step explanation:
y2-y1/x2-x1 = slope
4-(-2)/0-2=6/-2 or -3
y intercept is where line crosses y axis so it is 4.
Answer:
Slope: -3, y-intercept: 4
Explanation:
=> In order to find slope when a graph is given, the formula would be: [tex]\frac{rise}{run}[/tex](pronounced as "rise over run")
Rise = change in y-value = -3
Run = change in x-value = 1
Slope = [tex]\frac{rise}{run}[/tex] = [tex]\frac{-3}{1}[/tex] also could be written as -3
=> Now, to find the y-intercept, find a value on the graph where the line touches the y-axis, that's where x = 0, which would be your y-intercept;
Here the line touches the y-axis at "y = 4", this is also where x = 0;
therefore y-intercept = 4
Hope this helps!
Every person has blood type O, A, B, or AB. A random group of people are blood-typed, and the results are shown in the table. A 2-column table with 4 rows is shown. The first column is labeled Blood Type with entries O, A, B, AB. The second column is labeled Number of People with entries 22, 20, 6, 2. Use the table to determine the following probabilities. The probability that a randomly chosen person from this group has type B is . The probability that a randomly chosen person from this group has type AB is . The probability that a randomly chosen person from this group has type B or type AB blood is
Answer:
3/25 for type B, 1/25 for type AB, and 4/25 for both
Step-by-step explanation:
O goes to 22
A goes to 20
B goes to 6
AB goes to 2
22+20+6+2 = 50, so (number of people with a certain blood type)/50 = the answers for each question.
Work out the size of the angle X.
Give your answer correct to 3 significant figures.
Step-by-step explanation:
Recall the Ratio for tan
Tan(theta) = opposite / adjacent
Tan (x) = 9 / 5
solve for x (use Tan^-1(...) )
Answer:
Step-by-step explanation:
take x as reference angle
using tan rule
tan x=opposite/adjacent
tan x=9/5
tan x=1.8
x=tan 61 degree
x=61 degree
for remaining angle
remaining angle+90+61=180 degree(being sum of interior angle of a triangle)
remaining angle=180-151
remaining angle=29 degree
HELPPP ME PLEASE I REALLY NEED HELP
=====================================================
We'll use this formula
a & b/c = (a*c + b)/c
to convert from a mixed number to an improper fraction.
Let's convert the first mixed number to an improper fraction
a & b/c = (a*c + b)/c
3 & 3/4 = (3*4 + 3)/4
3 & 3/4 = 15/4
Repeat the same idea for the second mixed number as well
a & b/c = (a*c + b)/c
3 & 1/3 = (3*3 + 1)/3
3 & 1/3 = 10/3
--------------------
In short we have
3 & 3/4 = 15/43 & 1/3 = 10/3Doing these conversions is useful to be able to multiply the values like so:
(15/4)*(10/3) = (15*10)/(4*3) = 150/12 = (6*25)/(6*2) = 25/2
Now use your calculator to find that 25/2 = 12.5
We can then say....
12.5 = 12 + 0.5 = 12 + (1/2) = 12 & 1/2
The answer is choice F) 12 & 1/2 square yards.

HELP ME ASAP I NEED HELP SO BAD
Answer:
x = -3
Step-by-step explanation:
5x + 4y = 1
y = 1 - x
• Substitute (1 - x) into y:
5x + 4(1 - x) = 1
• Distribute:
5x + 4 - 4x = 1
• Combine like terms:
x + 4 = 1
• Subtract the 4 to solve for x:
x = -3

<1 and <2 form a linear pair. The measure of <1 = (2x+8) and the measure of <2 = (8x + 22). What is the measure of <1?
Answer:
Step-by-step explanation: Since the given problem states that the two angles, angle 1 and angle 2 form a linear pair, this means that they form a 180° line, so that:
measure angle 1 + measure angle 2 = 180°
Since measure of angle 2 is six more than twice the measure of angle 1, therefore:
measure angle 2 = 2 (measure angle 1) + 6
hence, substituting this into the first equation:
measure angle 1 + 2 (measure angle 1) + 6 = 180
3 (measure angle 1) = 174
measure angle 1 = 58°
Therefore,
measure angle 2 = 2 (measure angle 1) + 6
measure angle 2 = 2 (58°) + 6
measure angle 2 = 122*
