Answer:
Step-by-step explanation:
We can combine the -7x and the -2x and the left side to get -9x and the 23 and 13 on the right side to get 36.
This gives us
-9x + 12 = 36
Subtacting 12 from both sides gives us
-9x = 24
dividing by -9 gives us
x = - 8/3
Answer:
see below
Step-by-step explanation:
-7x + 12 – 2x = 23 + 13.0
Combine like terms
(-7x-2x) +12 = (23+13)
-9x +12 = 36
Subtract 12 from each side
-9x +12 -12 = 36 -12
-9x = 24
Divide each side by -9
-9x/-9 = 24/-9
x = -8/3

Answer:
296
Explanation:
To solve this problem, subtract 128 from 424.
424 - 128
296
Therefore, Jacobs total score is 296 after he loses 128 points from 424 points.
Answer: 296 points
Step-by-step explanation:
424 - 128 = 296
We now want to solve for x.
-4x + 11 = -1
-4x = BLANK?
X= BLANK?

At Sami's Shoe Warehouse, it takes 4 over 5 day to complete 1 over 10 of an order of sneakers. At this rate, how long will it take to complete the entire order of sneakers? (5 points)
6 days
8 days
11 and 1/4 days
12 and 1/2 days
HELP AASAP BRAINLIEST WILL BE AWARDED
Answer:
8 days
Step-by-step explanation:
if it takes 4/5 of a day to complete 1/10 of the order of sneakers, you are trying to determine how long it will take to get to 10/10.
so first we can determine what we have to multiply 1 by to get 10.
the answer is 10, so we can multiple by 10 to determine the amount of days it took:
4/5 x 10 and 1/10 x 10
therefore: 4/5 x 10 = 8
meaning, it would take 8 days to complete an entire order of sneakers.
A triangle is sitting on a horizontal line. The bottom left interior angle of the triangle is (9 + k) degrees. The exterior angle to the bottom left interior angle is (5 k minus 3) degrees.
What is the value of k?
k = 28
k = 29
k = 31
k = 42
Answer:
29
Step-by-step explanation:
If you mean the exterior angle at the same vertex as the interior,
(9+k)+(5k-3)=180
9+k+5k-3=180
6k+6=180
6k=174
k=29 degrees
Answer:
29

parallogram has opposite sides parallel
only with this point we can say that the given quadrilateral is a parallogram
Answer: i think its parallelogram.
Step-by-step explanation:
parallelogram has 2 sets of parallel sides, Opposite sides are congruent, opposite angles are congruent, all angles are NOT congruent, and all sides are NOT congruent.
hope its CORRECT :)

You pick a card at random, put it back, and then pick another card at random.
2 3 4 5
What is the probability of picking a number greater than 3 and then picking a 5?
Answer:
12.5%
Step-by-step explanation:
out of the 4 cards only two are >3 (4 and 5)
so 2/4 on the first choice (simplified to 1/2)
picking a 5 is 1/4 since there is only one 5
since they are happening at the same time multiply the two probabilities
1/2*1/4
=1/8
=0.125
=12.5%
I put in 6.32 for A but it’s still saying it’s wrong and I need the √ , I only need to answer this right to pass my summer school class someone please help me !
Answer:
Value of blank 1 is 2
Value of blank 2 is 10
Step-by-step explanation:
We are given that a and b are the lengths of legs of right angle in right angled triangle .
b = 3
We are also given that c is the hypotenuse
c = hypotenuse = 7
To find the value of 'a' we will use Pythagoras theorem
[tex]Hypotenuse^2 = perpendicular^2 +base^2\\c^2=a^2+b^2\\7^2=a^2+3^2\\7^2-3^2=a^2\\\sqrt{7^2-3^2}=a\\\sqrt{40}=a\\2\sqrt{10}=a\\[/tex]
Value of blank 1 is 2
Value of blank 2 is 10
Your teacher tells you that the hour hand on an analog clock will rotate 45° while you write a math quiz. If the quiz starts at 9:00, what time does it end? What is the angle between the starting and ending positions of the minute hand?
Answer:
1. 10:00 2. 360 degrees
Step-by-step explanation:
1. The hour hand rotated to move app. 1 hour.
2. A full circle all the a way around the clock would equal 360 degrees

solve this system of linear equations, separate the x- and y-values with a comma. -4x=-60-19y -7x=-48-19y
Answer:
The solution is at (-4,-4).
Step-by-step explanation:
(-4x=-60-19y)-1 Multiply by -1
4x = 60 + 19y
-7x = -48 - 19y Add both equations together
-3x = 12 Divide both sides by -3
x = -4
Plug this into the first equation to find the value of y
-4(-4) = -60 - 19y Multiply
16 = -60 - 19y
+60 +60 Add 60 to both sides
76 = -19y Divide both sides by -19
y = -4
Which two representations are considered to be only partial representations?
OThe equation and the verbal description
OThe verbal description and the graph
OThe table and the equation
OThe graph and the table
Answer:
D) The graph and the table
Step-by-step explanation:
The equation and the verbal description fully represent the situation because their representation is valid for all possible x values. On the other hand, the table and the graph only represent certain x values.

Using scientific notation, what is the solution to (4.5 * 108) / (1.5 * 105)?
please be neat when answering
Answer:
In fig. 9, angle Y = angle 110° (vertically opposite angles )
Angle x = angle z = 180 - 110 = 70° (angles on a straight line)
In fig 10, angle y = 78°
Angle x = angle z = 180-78 = 102°
In fig 11, angle x = 83°
Angle y = angle z = 180-83 = 97°
In fig 12, angle y = 37°
Angle x = angle z = 180-37 = 143°

What is the price per chocolate bar? (Round to 2 decimal places)
Answer:
$0.82
Step-by-step explanation:
The full answer is 0.8225, although I believe that I was supposed to round it to the nearest hundredth, so I did that. What I did was I divided 3.29 by 4.
Answer:
.82 per chocolate bar

Take the price and divide by the number of chocolate bars
3.29/4
.8225
Rounding to two decimal places
.82 per chocolate bar
The average cost of a movie ticket is $7.50. If this price increases annually by 7 percent, how much would a movie ticket cost in 9 years?
Question 5 options:
A)
$13.79 per ticket
B)
$12.55 per ticket
C)
$10.99 per ticket
D)
$11.21 per ticket
Answer:
A) $13.79 per ticket
Step-by-step explanation:
Hi, to answer this question we have to apply an exponential increase function:
A = P (1 + r) t
Where:
p = original price
r = increase rate (decimal form)
t= years
A = price after t years
Replacing with the values given:
A =7.50 (1+ [7/100]) ^9
A = $13.79 per ticket
