12.5=-1.5+b/0.1 solve for b
Solving the linear equation 12.5 = -1.5 + b/0.1, value of b is 1.4
What is an linear equation in one variable?Linear equation is an equation containing one unknown variable with power one and constants.
The standard form of an linear equation in one variable x is :
ax + b = 0 , where a, b are constants
x= -b/ a is solution of this equation or we can solve this equation by adding or subtracting same number to both sides.
To solve equation : 12.5 = -1.5 + b/0.1
Adding 1.5 to both sides
12.5 +1.5 = -1.5 +1.5 + b/0.1
14 = b/0.1
Multiply both sides by 0.1
0.1 *14 = 0.1(b/0.1)
1.4 = b
Therefore, the value of b on solving linear equation 12.5 = -1.5 + b/0.1 is 1.4

‐9−(‐12)= ‐9 + ___
=___
‐9−12= ‐9 +____
=___
Answer:
1st blank = 12
2nd blank = 3
3rd blank = (-12)
4th blank = (-21)
Step-by-step explanation:
for the first problem, just remeber that "minus a negitive, equals plus a positive" then -9 + 12, equals a positive 3.
and for the 2nd problem, when there is no negitive on the 2nd term, just remeber that if you change the sign in the middle, change the sign that follows. so that -9 - 12 then turns into -9 + (-12).

How to calculate the value of the missing lengthfrom the question, we have the following parameters that can be used in our computation:
The triangle
The height is calculated using the Pythagoras theorem as
h²= 60² - 36²
So, we have
h²= 2304
Evaluate
h = 48
Next, we have
(x -36) * 36 = 48 * 48
When evaluated, we have
x -36 = 64
So, we have
x = 64 + 36
Evaluate
x = 100
Hence, the value of x is 100

Without putting the first card back, you pick a second card at random. 4, 5, 6, 7 What is the probability of picking an odd number and then picking an even number? Write your answer as a fraction or whole number
send help
Answer: 1/3
Step-by-step explanation:
the card is not being replaced, so it is a dependent event.
Event A: picking an odd number
There are 4 cards total, and 2 odd numbered cards.
P(A) = 2/4 = 1/2
Event B: picking an even number.
There are now three cards total, because the card from Event A was not replaced. There are two even numbered cards.
P(B) = 2/3
P(A+B) = P(A) x P(B)
P(A+B) = 1/2 x 2/3 = 2/6 = 1/3
solve missing side of triangle one side is 4cm and other 8cm
Answer:
Using the "Pythagorean Theorem" formula:
a^2 + b^2 = c^2 we can find the hypotenuse of this triangle.
Replace the values of a, b, and c with it's actual values;
8^2 + 4^2 = __^2 ← our missing value
64 + 16 = 80, now we need to find the square root of 80:
√80 = 8.944, which equals to around 8.9.
so to rewrite:
8^2 + 4^2 = 8.9^2, so 8.9 is your answer.

Solve 5x = 81.2.
Round to the nearest ten-thousandth.
Answer:
The value of x is 2.7320
Step-by-step explanation:
.
Answer:
5x = 81.2, in order to find out the value of x, we need to isolate the variable by performing inverse operations on both sides of the equation.
5x = 81.2, when we look at 5x we can see that x and 5 are being multiplied.
The inverse operation of multiplication is division so we divide by 5 from both sides:
5x = 81.2.
÷5 ÷5
x = 16.24, and now since they want us to round to the nearest ten-thousandths, it is not needed because it does not reach the thousandths place so your answer is 16.24.
We can also double check this by replacing x with the value we found:
5x = 81.2
5(16.24) = 81.2
81.2 = 81.2, so it is correct because both match.
A fruit-drinking company tester a new flavor. In a taste test, 34% of the people taking part liked the new flavor. If 51 people liked the new flavor, how many people took the test? A. 34 B. 17 C. 150 D. 77
Answer:
C. 150
Step-by-step explanation:
The number of people who took the test is unknown, so call it x.
34% of x liked the flavor.
51 people liked the flavor.
That means that 34% of x is equal to 51.
34% of x = 51
0.34x = 51
x = 51/0.34
x = 150

rearrange it so that instead of 19 - 9x = 22 it is -9x + 19 = 22 then subtract 19 from both sides of the equation then simplify.
Answer:
A
Step-by-step explanation:
solving the original equation
19 - 9x = 22 ( subtract 19 from both sides )
- 9x = 3 ( divide both sides by - 9 )
x = [tex]\frac{3}{-9}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Maryanne's equation
- [tex]\frac{12}{5}[/tex] x + [tex]\frac{26}{5}[/tex] = 6 ( multiply through by 5 to clear the fractions )
- 12x + 26 = 30 ( subtract 26 from both sides )
- 12x = 4 ( divide both sides by - 12 )
x = [tex]\frac{4}{-12}[/tex] = - [tex]\frac{1}{3}[/tex]
solving Herb's equation
11 = 18x + 5 ( subtract 5 from both sides )
6 = 18x ( divide both sides by 18 )

A rental car company charges $25 per day to rent a car and $0.12 for every mile driven. Violet wants to rent a car, knowing that:
She plans to drive 125 miles.
She has at most $150 to spend.
pls help
Step-by-step explanation:
Identify the cost of 125 miles;
[tex]125 \times 0.12 = 15[/tex]
$15 for 125 miles.
Subtract 150 and 15;
[tex]150 - 15 = 135[/tex]
(Money remaining)
Divide 135 by 25 to identify how many days she can rent the car;
[tex]135 \div 25 = 5 \frac{2}{5} [/tex]
5 2/5 decreases to 5 as you can't rent a car for 5 2/5 days.
Answer: She can drive 125 miles and rent the car for 5 days.

Answer:
Two negative symbols combine to make a positive sign.
A) 7 - (-3)
B) a - (-5)
C) a - (-b)
A) 7 + 3 = 10 - (the difference is 10, subtract 0).
B) a + 5 = a - (-5) (difference is 'a', subtract -5).
C) a + b = a - (-b) (difference is 'a', subtract -b).
How to write each expression as a difference
To compose each expression as a difference, we ought to discover a proportionate expression within the shape of "x - y". Let's do that for each expression:
A) 7 + 3:
To speak to this as a contrast, able to rework it as follows:
7 + 3 = 10 -
B) a + 5:
To speak to this as a contrast, able to revamp it as takes after:
a + 5 = a - (-5)
C) a + b:
To speak to this as a contrast, able to rework it as takes after:
a + b = a - (-b)
In each case, we changed the given expansion expression into a contrast by including or subtracting a term with the inverse sign (e.g., including -5 to speak to +5 as a contrast).
