Answer:
amt of 25% solution to mix=6 gal
amt of 40% solution to mix=3 gal
Step-by-step explanation:
let x=amt of 25% solution to mix
9-x=amt of 40% solution to mix
25%x+40%(9-x)=30%*9
.25x+3.6-.40x=2.7
.15x=0.90
x=6
9-x=3

Solve for x;
|x+0.5|= -5
A. x= -5.5
B. x= -5.5 OR 4.5
C. No solution
Please answer asap. Thank you ❤
Answer:
your answer will be A
Step-by-step explanation:
Answer:
C. No solutionStep-by-step explanation:
Solve for x:
|x+0.5|= -5As we know an absolute value is always positive
So there is no solution to this equation as | x + 0.5 | ≥ 0 and the right side is negative
Correct option is C

Step-by-step explanation:
this is a version of the 3,4,5 rule which says that if the sides of a right triangle are 3 and 4, the hypotenuse is 5. Since 6 and 8 could be simplified to 3 and 4 respectively, you could make the hypotenuse (x) 10, which has the same relationship to 5 (division by 2). Hope this helps!

What does x equal to?
Answer:
Step-by-step explanation:
La X: En matemáticas la x hace referencia a una incógnita o variable. Variable quiere decir que puede tomar un valor específico dentro de conjunto. Por ejemplo, si tenemos "X+1=3" con X que pertenece al conjunto de los números enteros, la X toma el valor exacto de 2 del conjunto de los enteros.

Is ∆GAS ≅ △_____
By rule____
Answer:
ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Step-by-step explanation:
The given information are;
Statement [tex]{}[/tex] Reason
Segment [tex]\overline {SA}[/tex] is congruent to [tex]\overline {OL}[/tex] [tex]{}[/tex]As shown in the diagram provided
∠SAG is congruent to ∠LOI [tex]{}[/tex] As shown in the diagram provided
∠SGA is congruent to ∠LIO [tex]{}[/tex] As shown in the diagram provided
Therefore, ΔGAS ≅ ΔIOL By the Angle-Angle-Side (AAS) rule of congruency
Given that the the number of interior angles of triangle = 3 and the sum of the interior angles of a triangle = 180°, the third angle can be defined by specifying the measure of two of the angles
Therefore, the Angle-Angle (AA) rule of similarity can be used to prove the congruency of two triangles when they have one side of each triangle which are congruent.
Answer:
∆GAS ≅ △IOL By rule ASA, AAS
Step-by-step explanation:
By looking at the triangle, you can see two little quarter-circle things inside the triangle (I don't know what they are called). That means it has 2 angles. We already know that it can't be SSS or SAS because we have 2 angles, as I said.
If you look at the triangle's sides, you can see that there is a side with a dash on it. That means that it is a side in ASA, AAS, etc. So there we go. We've figured it out. There is one side and two angles. Therefore, our answer is ASA or AAS

The equation y=-2/3x-6 in standard form
The equation in the standard from is 2x + 3y = -18.
What is the linear equation?The linear equation is the algebraic form of equation whose variable has the exponent of one. It is the combination of two variables and a constant value present in them.
For the given situation,
The equation is y = -2/3 x - 6
The standard form of linear equation is Ax +By = C,
where A,B,C are numbers and x,y are intercepts.
⇒ [tex]y=\frac{-2}{3}x -6[/tex]
Taking LCM on RHS,
⇒ [tex]y=\frac{-2x-18}{3}[/tex]
⇒ [tex]3y=-2x-18[/tex]
Rearrange the equation in the standard from,
⇒ [tex]2x+3y=-18[/tex]
Hence we can conclude that the equation in the standard from is 2x + 3y = -18.

Mr. Wong wants to purchase 12 new smoke detectors for his house. Store A sells each smoke detector for $17 and Store B sells each smoke detector for $24. If Mr. Wong purchases all his smoke detectors at Store A, how much less will he spend than if he purchased all the smoke detectors at Store B?
Answer:
$84
Step-by-step explanation:
so for store A, you would do $17*12 smoke detectors, Which would give you $204. For store B you would do $24*12 smoke detectors. That is $288. Now all you do is 288-204=84. You would save $84 dollars going to store A
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The amount less spend by buying in store A than in store B is $84
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
The number of smoke detectors to be purchased.
= 12
Store A:
Cost of one smoke detector = $17
Cost of 12 smoke detectors.
= 12 x 17
= $204
Store B:
Cost of one smoke detector = $24
Cost of 12 smoke detectors.
= 12 x 24
= $288
Now,
The difference between the cost of 12 smoke detectors from store A to store B.
= $288 - $204
= $84
Thus,
The amount less spend by buying in store A than in store B is $84

is 6.1 or 6.18 bigger and how you know which one is larger.
Answer:
6.18 is larger
Step-by-step explanation:
Written with an equivalent number of decimal places, we are comparing ...
6.10
6.18
__
Use these rules for comparison of positive numbers:
1. If the left-most non-zero digits are in number places with different place values, the one with the digit in the highest place value is larger.
2. If the left-most non-zero digits are in number places with the same place value, the number with the larger digit is larger.
3. If the left-most non-zero digits are in the same number place and have the same value, replace those digits with 0, and repeat the comparison starting with the first test above. If one of the numbers has no more non-zero digits, use zero. If both of the numbers have no more digits, they are equal--neither is larger.
__
Following the above rules, we compare the units digits to find they are the same.
Then we compare the tenths digits, and find they are the same.
Then we compare the hundredths digit of 6.18 to 0 to find that 8 > 0, so 6.18 > 6.1

Find the slope of the line passing through each of the following pairs of points.
(0, -8), (0,4)
Answer:
The slope is undefined
Step-by-step explanation:
You can find the slope by doing change in y/change in x.
Y changed by 12 units while x changed by 0.
12/0 is undefined, so the slope is as well (on a graph, the line would be vertical)
0 or undefined or infinity
Step by step explanation:
slope = y2 - y1 / x2 - x1
= 4 + 8 / 0 + 0
= 12 / 0
= 0

Step-by-step explanation:
I have been doing this in Geometry.
We know perpendicular means opposite recipicoles and opposite slopes.
so.. the slope is 3 to get the y-intercept you do this.
(1, 2) Use the points it gave you and the slope 3 and put it is y=mx + b form
2 = 3(1) + b (I do this because I don't know what b is yet) (b = y-intercept)
2 = 3 + b (subtract 3 on both sides)
-1 = b
The equation is y = 3x - 1
