X=26
If you are able to put parenthesis in the the blank then you should put them around 4x+1 so that it looks like (4x+1)
Answer:
Equation: 4x+1+75=180
X= 26
105°
Step-by-step explanation:
When added, the two angles would create a flat angle of 180°, so just add the two angles:
4x+1+75=180
4x+76=180
-76 -76
4x=104
x=26
Input the solved x value into the angle to get the angle measure
4(26)+1 = 105

Answer:
x = -9, 3
Step-by-step explanation:
you cross multiply
Answer:
[tex]x=-9[/tex] or [tex]x=3[/tex]
Step-by-step explanation:
Cross multiply:
[tex]3/x+6=x/9\\\\\\(3) * (9)=x*(x+6)\\\\\\27=x^{2} +6x[/tex]
Subtract x^2 +6x from both sides:
[tex]27-(x^{2}+6x )=x^{2} +6x-(x^{2} +6x)\\\\\\-x^{2} -6x+27=0[/tex]
Factor left side of the equation:
[tex](-x+3)(x+9)=0[/tex]
Set factors equal to 0:
[tex]-x+3=0[/tex] or [tex]x+9=0[/tex]
Therefore, [tex]x=3[/tex] or [tex]x=-9[/tex]

A line is perpendicular to y=2/3x+2/3 and intersects the point (-2,4). What is the equation of this perpendicular line?
Answers
Answer:
y = - [tex]\frac{3}{2}[/tex] x + 1
Step-by-step explanation:
The equation of a line in slope- intercept form is
y = mx + c ( m is the slope and c the y- intercept )
y = [tex]\frac{2}{3}[/tex] x + [tex]\frac{2}{3}[/tex] ← is in slope- intercept form
with slope m = [tex]\frac{2}{3}[/tex]
Given a line with slope m then the slope of a line perpendicular to it is
[tex]m_{perpendicular}[/tex] = - [tex]\frac{1}{m}[/tex] = - [tex]\frac{1}{\frac{2}{3} }[/tex] = - [tex]\frac{3}{2}[/tex]
Using the point- slope form
with m = - [tex]\frac{3}{2}[/tex] and (x₁, y₁ ) = (- 2, 4) , then
y - 4 = - [tex]\frac{3}{2}[/tex] (x - (- 2) ) , that is
y - 4 = - [tex]\frac{3}{2}[/tex] (x + 2) ← distribute
y - 4 = - [tex]\frac{3}{2}[/tex] x - 3 ( add 4 to both sides )
y = - [tex]\frac{3}{2}[/tex] x + 1 ← in slope- intercept form
in this given figure find the value of x

QUESTION:- find the value of x
ANSWER:-[tex]180 - 6x + 180 - 5x + 180 - 4x = 180 \\ 360 + 180 - 15x = 180[/tex]
[tex]360 - 15x = 180 - 180 \\ 360 = 15x \\ 24 \degree = x[/tex]
Answer:
x = 24
Step-by-step explanation:
The exterior angles of the triangle sum to 360° , that is
5x + 4x + 6x = 360
15x = 360 ( divide both sides by 15 )

now we add 90
128
so the other angle is
52
so we just use the formulas
and
Side a = 26.56371
Side b = 43.14662
Side c = 34
so the side with a x on it is 26.6
so know we have to do the same thing but not including the top part
ok so the side with x on it is 18.8
so 26.6-18.8=7.8
x=7.8

A car owner decides to upgrade from tires with a diameter of 24.3 in to tires with a diameter of 26.1 in. If she doesn't update the onboard
computer, how fast will she actually be traveling when the speedometer reads 65 mph?
Although we want to solve for the linear speed of the upgraded tires, we do not have enough information for that. To fill up the formula v = rw, we only have the upgraded tires
r. but we do not know yet their w. However, since the speedometer counts rotations per hour and uses that to get the v of older tires, we can use that information to find the w
of the upgraded tires. Thus, let us solve first for w using the radius of the old tires and the reading of the speedometer.
Note: Do not forget that you are given the diameter and must still use that to get the radius. Also, do not forget that the diameter is given in inches, and you must convert that to miles, in order to be able to
cancel the time units. (1 mi = 63, 360 in)

The line that passes through the points (5, 3)
and (8. A) is perpendicular to the line
6x + 7y + 13 = 0. Determine the value of A.
Answers
Answer:
[tex] \frac{13}{2} [/tex]
Step-by-step explanation:
slope of the line that passes thru (5, 3) and (8, A)
[tex] = \frac{a - 3}{8 - 5} \\ \frac{a - 3}{3} [/tex]
the line that is perpendicular to the given line is
6x + 7y + 13= 0
finding the slop of this line :-
[tex]6x + 7y + 13 = 0 \\ 7y = - 6x - 13 \\ y = - \frac{6}{7} x - \frac{13}{7} [/tex]
Comparing with standard equation of a line
y = mx + c
where m is the slop and c is the y- interceptm = - 6/ 7
Since, the two lines are perpendicular to each other the product of their slopes will be - 1
[tex] \frac{a - 3}{3} \times \frac{ - 6}{7} \\ \frac{ - 2(a - 3)}{7} = - 1 \\ - 2a + 6 = - 7 \\ - 2a = - 7 - 6 \\ - 2a = - 13 \\ 2a = 13 \\ a = \frac{13}{2} [/tex]

A pharmaceutical company collects data on the side effects participants report for a drug it is testing. The company finds that the probability of experiencing a headache is 5 percent and the probability of experiencing both a headache and heartburn is 2 percent. If the probability of experiencing a headache or heartburn is 8 percent, what is the probability of experiencing heartburn?
1 percent
5 percent
11 percent
15 percent
Answers
Answer:
the answer is 5 percent
Step-by-step explanation:
The probability of experiencing heartburn is 5 percent. Therefore, option B is the correct answer.
What is the probability?Probability can be defined as the ratio of the number of favorable outcomes to the total number of outcomes of an event.
Given that, the probability of experiencing a headache is 5 percent and the probability of experiencing both a headache and heartburn is 2 percent.
Let Event A: Headache and Event B: Heartburn.
P(A)=0.05, P(A∩B)=0.02
The probability of experiencing a headache or heartburn is 8 percent, hence:
P(A∪B)=0.08
Now, P(A∪B)=P(A)+P(B)-P(A∩B)
0.08=0.05+P(B)-0.02
P(B)=0.05 or 5%
Therefore, option B is the correct answer.

Answer:
it depends on what the question is (no question is given)
Step-by-step explanation:
What you add or subtract will depend on the problem you're trying to solve, and how you're trying to solve it.
Perimeter
The two left-side vertical segments are 13 and 3. The right-side vertical segment is 16. As you can see, these have the same total: 16.
The top horizontal segment has a length of 21. The two bottom horizontal segments have lengths 16 and 5, for a total of 21—the same as the top segment.
For simple L-shaped figures like this, the overall horizontal lengths and the overall vertical lengths are the same as they would be for a rectangle that is 21 wide and 16 high.
P = 2(L+W) = 2(21+16) = 2(37) = 74 units
__
Area
The dashed lines divide this figure into 3 rectangles.
left side: 16 wide by 13 high
upper right: 5 wide by 13 high
lower right: 5 wide by 3 high
You can see that the vertical measures must "add up", as must the horizontal measures. This fact helps you determine the lengths of the unmarked sides.
You can compute the area from the three rectangles identified above, or any of several other ways. One of my favorite is to compute the overall area of the 21 wide by 16 high rectangle, then subtract the 16 wide by 3 high white space at lower left.
area = 21·16 -16·3 = 16·(21 -3) = 16·18 = 288 . . . . square units
Adding the 3 rectangles identified above gives ...
16·13 +5·13 +5·3 = 208 +65 +15 = 288 . . . . same area

Ali cycles x km in 3 hours. If he maintains the same
average speed, how far can he cycle in y minutes?
Answers
Answer:
xy/180 km
Step-by-step explanation:
Mathematically, we have it that;
Speed = distance/ time
If he cycles x km in 3 hours
We know that ; 60 minutes = 1 hr
3 hours = 3 * 60 = 180 minutes
So the speed in km per minutes will be;
x km/180 minutes = x/180 km/minute
Recall,
Distance = speed * time
= x/180 * y = xy/180 km
