Answer:
x<_2
Step-by-step explanation:
first off solve this like a regular equation the >_ dosent matter till later
so basically first multiply - by 13 and -x so you get -13 and x (multiplying two negatives = a positive)
so its 5x-13+x>_9x-7
add 5x and x to get 6x-13 on one side
then you get 6x-13>_9x-7 then subtract -9x from both sides
so its now -3x-13>_-7 add 13 so you get -3x>_6
then divide both sides by -3 (when you divide an equation with a >< or <_ >_ by a negative number that sign switches) so it will now be x<_2
that your final answer hope this helps :)

16 = (16 – 4 X 2) =
Answer:
False
Step-by-step explanation:
PEMDAS is your order of operations, so you would do the multiplication in the parenthesis first.
[tex](16-4*2) = (16-8) = 8[/tex]
16 isn't equal to 8 so the answer would be false.
Answer:8
Step-by-step explanation:4 times 2=8 so 16-8=8

Consider the line y = 2/3x-4
A line parallel to the graph of the line would have a slope of
A line perpendicular to the graph of the line would have a slope of
Answer:
For the parallel line it will still have a slpoe of 2/3
Step-by-step explanation:
as for the perpendicular line it will be double like 4/6 so it can meet it at a 90° angle.
Bill works for a company that makes candy bars. Bill's job is to pack 10 candy
bars in every box. Bill then places 12 boxes in a shipping carton. Each carton
shipped contains how many candy bars?
Answer:
120 bars
Step-by-step explanation:
If Bill packs 10 candy bars in every box and there are 12 boxes in every shipping carton, then that would mean there are 12 sets of 10 candy bars. Meaning that you would multiply 10 by 12 since there are 12 boxes and 10 candy bars in each box (which would give you 120).

Jim had 360 stamps he sold 1/3 of them on Monday and 1/4 of the remainder on Tuesday how many stamps did he sell on Tuesday
Answer:
60
Step-by-step explanation:
Since Jim sold 1/3 of his stamps on Monday, the remainder would be 2/3 of his total stamps.
Divide 360 stamps by 3. Minus the stamps sold on Monday from 360 to get the remainder.
stamps sold on Monday = 360 ÷ 3 = 120
remainder = 360 - 120 = 240
He sold 1/4 of the remainder on Tuesday.
Divide the remainder by 4.
stamps sold on Tuesday = 240 ÷ 4 = 60
He sold 60 stamps on Tuesday.
f(a) = 2a - 1
g(a) = 4a
- 1
Find f(a) + g(a)
Answer:
[tex]f(a)+g(a)=6a-2[/tex]
Step-by-step explanation:
So we have the two functions:
[tex]f(a)=2a-1\text{ and } g(a)=4a-1[/tex]
And we want to find f(a) + g(a).
So, substitute:
[tex]f(a)+g(a)[/tex]
This is the same as:
[tex]=(2a-1)+(4a-1)[/tex]
Combine like terms:
[tex]=(2a+4a)+(-1-1)[/tex]
Add or subtract:
[tex]=6a-2[/tex]
And we're done!
John and Maria solved the same equation using two different methods.
Compare and contrast John and Maria’s methods. Explain how they arrived at the same solution.
Answer:
John's steps
-distrubute the 2 through the parentheseas
-subtract 18-12
-subtract 10 on both sides
-divide both sides of the equation by 2
-y=-2
Marias steps
-divide both sides by 2
-subtract both sides by -5
-y=-2

If a card is chosen from a standard
deck of cards, what is the probability
of getting a five or a seven?
Answer:
5/52 for getting a 5
7/52 for getting a 7
Answer:
Step-by-step explanation:
52 cards in a standard deck. Four 5's and four 7's.
4/52 = 5
4/52 = 7
4/52+4/52= 2/13
2/13 as a percent is 15.384615384615%
that simplified is 15.4%
or just 15%

in examination of 300 full marks, a student secured 110 marks and failed by 10 marks. what is the pass percent?
Answer:
36.67 %
Step-by-step explanation:
Pass mark = 110 marks
Total mark = 300 marks
Pass percentage=
[tex] \frac{pass \: mark}{pass \: percentage} \times 100[/tex]
Substitute values into the equation
[tex] \frac{110}{300} \times 100[/tex]
Cross cancel common factor: 100
[tex] \frac{110}{3} = 36 \frac{2}{3} \% \: or \: 36.67 \%[/tex]
What is the equation of the line if slope is -2 and y-int is 9
Answer:
y = -2x + 9
Step-by-step explanation:
Let's start from the -2x, the slope is -2. The x is basically what says, this is the slope. The plus nine is the y-intercept. If you think in graph terms (which is how you solve this problem) you will see that on the y-axis the line will intercept at the 9. The every x integer it goes down it goes that times two. For example, if you go sideways 1 spot, the line will be at y=11.

Suppose a Hispanic Heritage festival is held in a park that is 58 yards long and 43 yards wide.
What is the diagonal length of the festival'area? Round your answer to the nearest tenth of a

D 72.3 yards
E
Submit
Pu
Answer:
[tex]D = 72.2\ yd[/tex]
Step-by-step explanation:
Given
[tex]Length\ (L)= 58\ yd[/tex]
[tex]Width \ (W)= 43\ yd[/tex]
Required
Determine the diagonal (D)
The relationship between D, L and W can be gotten using Pythagoras Theorem:
[tex]D^2 = L^2 + W^2[/tex]
Substitute values for L and W
[tex]D^2 = 58^2 + 43^2[/tex]
[tex]D^2 = 3364 + 1849[/tex]
[tex]D^2 = 5213[/tex]
Take Square root of both sides
[tex]D = \sqrt{5213}[/tex]
[tex]D = 72.2011080247[/tex]
[tex]D = 72.2\ yd[/tex] (Approximated)

find x so that q parallel r
Answer: x = 7

x = 7
A student standing on top of a building sees a bird flying that is 25ft away and 20 ft above the top of the building. The student also sees a car on the ground at and angle of depression 70°. The car is directly below the flying bird.A diagram of the situation is shown below
Answer: The height of the building is 41.2 ft
Step-by-step explanation:
Here we want to find the height of the building.
To do so, the first step is to find the horizontal distance between the student and the car/bird (which represents the common cathetus between the two triangle rectangles).
For the top triangle rectangle, we know one cathetus and the hypotenuse, and we can use the Pythagorean's theorem to find the other cathetus.
A^2 + B^2 = H^2
Where A and B are the cathetus, and H is the hypotenuse.
Then we have:
20^2 + B^2 = 25^2
B^2 = 25^2 - 20^2
B = √( 25^2 - 20^2) = 15
Then the horizontal distance between the student and the car is 15ft, and we also know the angle at which this cathetus is adjacent, the angle is 70°.
Then we can use the relationship:
Tan(A) = (opposite cathetus)/(adjacent cathetus)
Where the opposite cathetus woud be the height of the building, then:
Tan(70°) = H/15ft
Tan(70°)*15ft = H = 41.2 ft

What is m∠PTQ???????????
Answer:
m∠PTQ = 40°
Step-by-step explanation:
From the picture attached,
Two lines PS and RQ are intersecting each other at a point T.
Vertical angles formed at the point of intersection T will be equal in measure.
m∠PTQ = m∠STR and m∠PTR = m∠QTS
Therefore, (x + 28)° = (2x + 16)°
28 - 16 = 2x - x
12 = x
m∠PTQ = (x + 28)°
= 12 + 28
= 40°
Therefore, measure of angle PTQ is 40°.
