Answer/Step-by-step explanation:
Since 320 is 10 times 32. The answer for 320 divided by 4 is going to be 10 times the answer of 32 divided by 4.
320 ÷ 4 = 80
32 ÷ 4 = 8
As 320 is 10 times of 32 then values results also 10 times.
What is Division?One of the four fundamental mathematical operations, along with addition, subtraction, and multiplication, is division. Division is the process of dividing a larger group into smaller groups so that each group contains an equal number of things. It is a mathematical operation used for equal distribution and equal grouping.
Given:
We have to divide 32 by 4.
The division is as follow:
= 32/4
= (4 x 8)/ 4
= 8
If we multiply 10 to 32 then we get 320.
Then, if we multiply 10 to 8 we get
= 10 x 8
= 80

Answer:
-4
Step-by-step explanation:
Two legs of the triangle are congruent as shown by the tick marks. This means that this is an isosceles triangle; in an isosceles triangle, the two base angles are also congruent. Which means <A and <B are congruent.
So to solve for x, set 28 and 10x+68 equal to each other.
28=10x+68
First, subtract 68 from both sides
-40=10x
Then, divide both sides by 10
-4=x
If you want to check your answer plug -4 back into the original equation.
28=10(-4)+68
28=-40+68
28=28, which is true, therefore -4 is correct.

pls help me find slope ps first person with answer gets the brainest
Answer:
The slope is 1
Step-by-step explanation:
The line's equation is y=x+3
4-(-1)/1-(-4)=5/5=1. That's the slope.
Answer:
1
Step-by-step explanation:
Use the following equation:
slope (m) = [tex]\frac{y_2 - y_1}{x_2 - x_1}[/tex]
Let:
([tex]x_1 , y_1[/tex]) = ([tex]-4 , -1[/tex])
([tex]x_2 , y_2[/tex]) = ([tex]1 , 4[/tex])
Plug in the corresponding numbers to the corresponding variables:
m = [tex]\frac{4 - (-1)}{1 - (-4)}[/tex] = [tex]\frac{4 + 1}{1 + 4} = \frac{5}{5}[/tex]
[tex]\frac{5}{5} = 1[/tex]
Your slope is 1.

Bus X, Bus Y and Bus Z leave the bus terminal every 35 minutes, 40 minutes and 42 minutes respectively. Given that the 3 buses leave the interchange together at 0620, what would be the next time the three buses leave together?
Answer:
Step-by-step explanation:
Find the lowest common multiple between the numbers
35 = 5×7
40 = 2³×5
42 = 2×3×7
So the lowest common multiple is:
2³×3×5×7 =840 minutes
840 minutes is 14 hours so the next time they are all at the interchange is 2020 hours.
Mr. Marcos bought chicken and beef from the butcher and fish from the fish market for a barbecue. Thee ratio of the weight of chicken to the weight of the beef to the weight of the fish he bought was 3 : 1 : 5. He bought 10 pounds of fish. What was the total weight of meat he bought from the butcher?
Answer:
8 pounds
Step-by-step explanation:
Total ratio = 3 + 1 + 5 = 9
x = total pounds of chicken, beef and fish bought
equation for pounds of fish bought = 5/9 × x = 10
divide both sides by 9/5
x = 18
pounds of chicken bought = 3/9 x 18 = 6 pounds
pounds of beef bought = 1/9 x 18 = 2 pounds
total weight of meat bought = 6 + 2 = 8 pounds

Find the coordinates for points are that proves figure trap is an isosceles trapezoid?
Answer:
Coordinates of point R → (c - a, b)
Step-by-step explanation:
From the picture attached,
By the property of an isosceles trapezoid,
PX = AY = a
Therefore, horizontal distance of Y from the origin PY = AP - AY
PY = c - a
Vertical distance of point R from x-axis (RY) = b
Therefore, coordinates of point R will be (c - a, b).

In an inverse variation, X = -8 when
y= - 1/4. What is the value of y when x = 4?
Step-by-step explanation:
xy = k, where k is a real constant.
When y = -1/4, x = -8.
=> k = (-8)(-1/4) = 2.
Therefore when x = 4,
y = k/x = (2)/(4) = 0.5.
In an inverse variation the value of y is 0.5
What is the value of y ?
In an inverse variation, X = -8 wheny= - 1/4.
y= - 1/4.
the value of y when x = 4
In the equation xy = k, k is a real constant.
X equals -8 at y = 1/4.
=> k = (-8)(-1/4) = 2.
Consequently, if x = 4,
y = k/x = (2)/(4) = 0.5.
In an inverse variation the value of y is 0.5.
Solving an Inverse Variation Problem:
The variation formula is either y = k/x or k = xy.Replace with the supplied values to determine the value of k.With the known value for k, rewrite the variation equation as y = k/x.Find the unidentified by substituting the remaining values.To learn more about inverse variation refer to:

Answer:
-3 and -4
Step-by-step explanation:
x = 1st number
y = 2nd number
set up system of equations:

9x + 6y = -51
5x = -15
x = -3
find y: 2(-3) + 3y = -18
-6 + 3y = -18

Answer:
5. 28.39
6. 58.18
Step-by-step explanation:
5. To find x, use tangent since you know the opposite and adjacent legs
tangent is opposite/adjacent
tan(x)=20/37
x=tan-1(20/37)
x=28.39
6. you want to find the hypotonuse of XYZ to use tangent to find angle W
Sin(25)=15/x
0.423=15/x
0.423x=15
x=35.46
this is the hypotonuse
now use tangent to find W
tan(x)= 35.46/22
x=tan-1(35.46/22)
x=58.18
