There are two mystery numbers. The sum of 2 times the first number and 3 times the second number is -18. The sum of 3 times the first number and 2 times the second number is -17. What are the two numbers?
Answer:
-3 and -4
Step-by-step explanation:
x = 1st number
y = 2nd number
set up system of equations:
2x + 3y = -18
3x + 2y = -17
elimination method: multiply 1st equation by -2 and second by 3
-4x - 6y = 36
+
9x + 6y = -51
5x = -15
x = -3
find y: 2(-3) + 3y = -18
-6 + 3y = -18
3y = -12
y = -4

Find the number whose 23.2% is 34.8.
Answer:
The required number will be:
x = 150Step-by-step explanation:
Let 'x' be the number
so
23.2% of x = 34.8
23.2% × x = 34.8
23.2/100 × x = 34.8
0.232x = 34.8
divide both sides by 0.232
0.232x/0.232 = 34.8/0.232
x = 150
Therefore, the required number will be:
x = 15020 chairs at 5 tables = ? chairs per table
Answer:
4 chairs per table
Step-by-step explanation:
Answer:
4 Chairs Per Table
Step-by-step explanation:
There are 20 tables at 5 tables.
We need to find the number of chairs per person.
Divide 20 by 5.
[tex]\frac{\text{Total Number of Chairs}}{\text{Total number of Tables}} =\frac{20}{5}=\frac{20/5}{5/5}=\frac{4}{1}=\boxed{4}[/tex]
There should be 4 chairs per table.

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

Can some help ...:.....0
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.

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.

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:

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.
