Answer:
Step-by-step explanation:
Hello,
let s regroup the terms
2ax - 15 = 3(x + 5) + 5(x - 1) *** add 15 to both sides ***
<=> 2ax = 15 + 3x + 15 + 5x - 5 *** develop to remove the parentheses***
<=> 2ax = 8x + 25 *** simplify ***
<=> (2a-8)x = 25 *** subtract 8x from both sides ***
<=> (a-4)x=25/2 *** divide by 2 both sides ***
There is no solution is a-4 = 0 ,
because it would mean 0 = 25/2 and this is not possible
So it gives a = 4
Thanks
In the case when no value of x satisfies the equation so there the value of a should be 4.
Calculation of the value of a:Since
the equation is
2ax - 15 = 3(x + 5) + 5(x - 1)
2ax = 15 + 3x + 15 + 5x - 5
2ax = 8x + 25
(2a-8)x = 25
So a = 4
hence, In the case when no value of x satisfies the equation so there the value of a should be 4.

What is an equation that goes through (12, 5); m = -3
Please help
Answer:
Step-by-step explanation:
Use this formula:
y - y1 = m ( x - x1 )
We are told m = -3 and given the point (12 , 5) ---- > so x1 = 12 and y1= 5
Put these values into the formula above and you get:
y - y1 = m ( x - x1 )
y - 5 = -3 ( x - 12 )
y - 5 = -3x + 36
y = -3x + 36 + 5
y = -3x + 41

How to calculate unit price of something?Unit means 'single entity', the fundamental constructing block. Usually, it is 1 in mathematics and science.
Thus, unit price of something is price of 1 thing.
Then suppose we're taking about price of mangoes, then unit price will denote the price of 1 mango.
WE have been given a recipe for ice cream calls for 56 fluid ounces of milk.
We need to find How many pints of milk are there in the recipe.
There are 16 fluid ounces in 1 pint then;
56 ÷ 16
= 3.5
The answer is 3.5 pints because there are 16 fluid ounces in one pint which means that there are two pints in 32 fluid ounces and 3.5 pints in 56 fluid ounce.

Lucia deposits $44.60 into her bank account on Tuesday Morning. Tuesday afternoon, she withdraws to $26.30 and $21.30. Does Luisa have more or less money on Tuesday night than she did on Monday night? Does this equation tell whether Luisa has more or less money on Tuesday night than Monday night? Explain.
Answer:
Less than
Step-by-step explanation:
Using the data from the question, we can create the following equation to solve this...
44.60 - (26.30 + 21.30) = x
44.60 - (47.60) = x
-3 = x
As you can see Lucia withdrew more money than what she actually deposited which means that her account balance on Tuesday Night is less than what it was on Monday night before the initial deposit. This can all be seen using the above equation which is designed.
- Heidi bought an 18 ounce bottle of Castor Oil. If each dose is ounce, how many doses are
in the bottle?
Answer:
18 doses
Step-by-step explanation:
Since it says each dose is a ounce.
is this reasoning inductive or deductive? explain why.
1. all pennies are copper. if your friend gives you a penny, you conclude that the penny is copper colored.
2. all even numbers are divisible by 2. 28 is even. therefore, 28 is divisible by 2.
please help me out with this and also include reasoning! thank you so much!
Answer:
No. 1 is inductive, cos the evidence is based on proberbility as not all pennies are silver color, since thier color could change over time (fade)
while
No 2 is deductive since all even numners are divisible by 2, there is a full assurance of the outcome.
Answer: The reasonings are deductive. They tried to do a trick question I think.
Step-by-step explanation: There both deductive because the first sentence has a key word which is Conclude. The word might not seem to matter until you look up what deductive means. Deductive and Inductive are different because one is specifics observation and then draw a conclusion and the other is specifics conclusion follows a general theory. And the key word in deductive is conclusion in the first sentence it says that you conclude. Deductive means a conclusion that follows a general theory. The deductive is following a general theory which means if the facts are right then the conclusion should be right. The deductive makes sense in the first because if the facts that all the pennies are copper is true then the penny your friend gave you should be copper. The second sentence same thing if the fact was right then any number that is even can be divisible by 2. So deductive makes sense in both sentences. Inductive makes sense it inside one on the sentences not both. Inductive makes sense inside the first because the person could have seen that the pennies were all made of copper. i think that it being deductive is a better choice that inductive and if you still are confused you can look up "difference between inductive and deductive reasoning" and go to images it should have a blue and pink picture of the definition of them. Sorry I wrote it so long you can just shortened it down for the answer.
