Answer:
0
Step-by-step explanation:
The * means multiplication where the ^ means exponents, so you multiply in this case.
-6 * -6 = 36
Two negatives equals a positive.
PEMDAS shows that multiplication and division occurs first so...
7 * -6 = -42
36 + -42 + 8
-8 + 8
= 0
You can search it up to see what PEMDAS is.
The midpoint of CD is M (-3, -7). If the coordinates of C are (-2, -10), what are the coordinates of D?
Answer:
Answer: (-4, -4)
Step-by-step explanation
2(-3) = -2 + X 2(-7) = -10 + Y
-6 = -2 + X -14 = -10 + Y
+2 +2 +10 +10
-4 = X -4 = Y

Question 5: A car used 1164 gallon of gas to drive ya of a mile. At this rate, how many miles can the car travel using 1
gallon of gas?
I
Answer:
Hello! Your answer is BELOW
Step-by-step explanation:
Car will cover 16 miles in 1 gallon of the gas.
We can solve this question by unitary method.
∵ A car used [tex]\frac{1}{64}[/tex] gallons of gas to drive the distance = [tex]\frac{1}{4}[/tex] miles
∴ Car used 1 gallons to drive the distance = [tex]\frac{1}{4} \\\\\frac{1}{64}[/tex]
= [tex]\frac{64}{1} X \frac{1}{4}[/tex]
= [tex]\frac{64}{4}[/tex]
= 16 miles
Therefore, car will cover 16 miles in 1 gallon of the gas.
Hope I helped! Hope you make an 100%.

Now We know
[tex]\\ \sf\longmapsto tan30=\dfrac{7}{B}[/tex]
[tex]\\ \sf\longmapsto \dfrac{1}{\sqrt{3}}=\dfrac{7}{B}[/tex]

Step-by-step explanation:
5) = 0 (-17 + 20 = 3,... 3 + -3 = 0)
6) = -34 (-34 + 25 = -9,... -9 + -25 = -34)
9) = -4 (7 + -11 = -4)
Chow,...!
Answer:
for question 5 the answer is 0.
for question 6 the answer is -34.
for question 9 the answer is -4.
Step-by-step explanation:
question 5: -17+20 can also be written as 20-17 which is equal to 3. Next, we have to add 3 with -3. 3+(-3) is the same as 3-3 which equals 0.
question 6: 25-25 = 0, and the remainder is -34.
question 9: 7-11 can also be written as -11+7, which is equal to -4.

9514 1404 393
Answer:
[[274][895][136]]
Step-by-step explanation:
Starting with the middle row, we need a product of two single-digit numbers that is between 53-1 = 52 and 53-9 = 44. Possible products are 5×9=45 and 6×8=48. This means the number in the middle position in the left column must be 8 or 5.
The middle number in the left column cannot be 5, because we must be able to get -5 by subtracting that number from a sum that is at least 3 = 1+2. So, the middle number in the left column is 8, the other two numbers in that column are 1 and 2, and the other two numbers in the middle row are 5 and 9.
There is no product of single-digit numbers that is 30-1 = 29, so the upper left number must be 2, and the bottom left number must be 1. The other two numbers on the top row must be 4 and 7, so that row's equation is 2+4×7=30.
The only remaining digits are 3 and 6. In order to have -3 on the bottom row, the equation there must be 1×3-6 = -3. Then the middle digit must be divisible by 3, so must be 9.
Our solution is ...
row 1: 2 + 7 × 4 = 30
row 2: 8 + 9 × 5 = 53
row 3: 1 × 3 - 6 = -3
And that makes the column equations be ...
col 1: 2 - 8 + 1 = -5
col 2: 7 + 9 / 3 = 10
col 3: 4 × 5 - 6 = 14

Answer:
a. circumference
b. area
c. area
d. circumference
Step-by-step explanation:
a. You are using the circumference formula to find the distance around a CIRCULAR track, if you used area, that would include the space in between the track as well. You are only trying to find the track line. ( you can draw a picture of a track and show what you are finding. )
b. You are trying to find the amount of area that the tiles make up in the circular floor, how much of the floor the tiles take up.
c. You are trying to find how much of the oil takes up of the WHOLE bottom of the frying pan.
d. Finding the circumference of your wheel can help determine the distance the car traveled. If you used area, it would not be useful.

Referring to the figure, find the value of x
Answer:
Step-by-step explanation:
By the triangle angle-sum theorem, all the angles of a triangle have to add up to equal 180°. Thus,
72° + 5x° + x° = 180° and
72° + 6x° = 180° and
6x° = 108° so
x = 18°
Each chef at "Sushi Emperor" prepares 15 regular rolls and 20 vegetarian rolls daily. On Tuesday, each customer ate 2 regular rolls and 3 vegetarian rolls. By the end of the day, 4 regular rolls and 1 vegetarian roll remained uneaten. How many chefs and customers were in "Sushi Emperor" on Tuesday?
9514 1404 393
Answer:
2 chefs13 customersStep-by-step explanation:
Let x and y represent the numbers of chefs and customers, respectively. We can write equations for the different kinds of rolls made and eaten:
15x -2y = 4 . . . . . 4 regular rolls were uneaten
20x -3y = 1 . . . . . 1 vegetarian roll was uneaten
Using the "cross multiplication method", the solution can be found to be ...
Δ1 = (15)(-3) -(20)(-2) = -5
Δ2 = (-2)(-1) -(-3)(-4) = -10
Δ3 = (-4)(20) -(-1)(15) = -65
1/Δ1 = x/Δ2 = y/Δ3, so we have ...
x = Δ2/Δ1 = -10/-5 = 2 . . . . there were 2 chefs
y = Δ3/Δ1 = -65/-5 = 13 . . . there were 13 customers

Additional comment
The version of the "cross multiplication method" I use for solving two linear equations is this. Write the equations in general form. List the coefficients in two rows, repeating the first column so there are 4 columns. Form "cross products" of the coefficients taking columns pairwise. Use these cross products to find the variable values.
In general form, these equations are ...
15x -2y -4 = 020x -3y -1 = 0Then the rows of coefficients are ...
[ 15, -2, -4, 15 ]
[ 20, -3, -1, 20 ]
The "cross multiplication" subtracts the product on the up-diagonal from the product on the down-diagonal. If we label the results Δ1, Δ2, Δ3, we get the results shown above. These "cross products" are used in the equation ...
1/Δ1 = x/Δ2 = y/Δ3
to find the values of x and y.
Some videos I have seen of this method write the two rows of coefficients shifted to the left, and use a different final equation for the solution. The result is the same. I find the extra shifting to make the process confusing and difficult to remember.
I prefer this method when there is no simple way to do substitution or elimination. In the end, it takes slightly fewer math operations than would be required by either of those methods in such cases.
