-21 = 1/2c - 11
Answers
Answer:
c = -20
Step-by-step explanation:
-21=1/2c-11
-21+11=1/2c
-10=1/2c
-10*2=c
-20=c
Answer:
c = - 20
Step-by-step explanation:
Given
- 21 = [tex]\frac{1}{2}[/tex] c - 11 ( add 11 to both sides )
- 10 = [tex]\frac{1}{2}[/tex] c ( multiply both sides by 2 to clear the fraction )
- 20 = c , that is
c = - 20

Mrs Wong paid $18.60 for a chocolate cake and 6 egg tarts. Mrs Tan paid $29.40 for the same type of chocolate cake and 24 egg tarts. How much did one chocolate cake cost?
Answers
Answer:
$15
Step-by-step explanation:
1 chocolate cake and 6 egg tart costs $18.60.
1 chocolate cake and 24 egg tarts cost $29.40.
Find the difference in egg tarts first.
Difference in egg tarts = 24 - 6 = 18
Then, the difference in cost.
$29.40 - $18.60 = $10.80
Find the cost of 1 egg tart.
18 egg tarts = $10.80
18 egg tarts = $10.80
1 egg tart = $10.80 ÷ 18 = $0.60
To find the cost of a chocolate cake, you minus the cost of 6 tarts from $18.60.
6 egg tarts = $0.60 × 6 = $3.60
6 egg tarts = $0.60 × 6 = $3.601 chocolate cake = $18.60 - $3.60 = $15

Answers
The product 3/2 x 3/4 is greater than 3/8.
The correct answer is option (C) 3/2 x 3/4
What is rational number?"It is a number which is expressed as the ratio of two integers, where the denominator should not be equal to zero."
For given example,
We have been given a rational number 3/4 and the product of four rational numbers.
We need to find which product is greater than 3/4
3/4 = 0.75
Consider,
a) 1/2 x 3/4 = 3/8
⇒ 3/8 = 0.375
⇒ 0.375 < 0.75
b) 5/6 x 3/4 = 15/24
⇒ 15/24 = 0.625
⇒ 0.635 < 0.75
c) 3/2 x 3/4 = 9/8
⇒ 9/8 = 1.125
⇒ 1.125 > 0.75
⇒ (3/2 x 3/4 ) > 3/4
d) 2/5 x 3/4 = 3/10
⇒ 3/10 = 0.3
⇒ 0.3 < 0.75
Therefore, the product 3/2 x 3/4 is greater than 3/8.
The correct answer is option (C).

find the value of x when 6 - 4x = 6x - 8x + 12
Answers
Answer:
x = -3
Step-by-step explanation:
Step 1: Write out equation
6 - 4x = 6x - 8x + 12
Step 2: Combine like terms (x)
6 - 4x = -2x + 12
Step 3: Add 4x on both sides
6 = 2x + 12
Step 4: Subtract 12 on both sides
-6 = 2x
Step 5: Divide both sides by 2
-3 = x
Step 6: Rewrite
x = -3
Answer:
The answer is x= -3
Step-by-step explanation:
6 - 4x = 6x - 8x + 12
First, add like terms. (6x-8x)
6-4x=-2x+12
Then "add" 4x to both sides.
6=2x+12
Then subtract 12 from both sides.
-6=2x
The final step is to divide. Divide 2 from both.
Your answer is x= -3

PLEASE HELP!!!! Explain why a quadratic equation with a positive discriminant has two real solutions, a quadratic equation with a negative discriminant has no real solution, and a quadratic equation with a discriminant of zero has one real solution.
Answers
Hey there! I'm happy to help!
In the quadratic formula, the discriminant is square rooted. In this formula you have a ± before this radical. If the discriminant is positive, the solution can be either subtracting or adding the number, so there are 2 real solutions.
If it is 0, subtracting or adding are the same, so there will be just one solution.
You cannot have a negative square root. It is impossible with real numbers, so there are no real solutions.
I hope that this helps! Have a wonderful day! :D
The zeroes based on nature of discriminant is described below.
We know that,
A quadratic equation is of the form ax + bx + c = 0,
Where a, b, and c are constants and x is the variable.
The discriminant of a quadratic equation is given by the expression,
⇒ b² - 4ac.
If the discriminant is positive (b² - 4ac > 0),
Then the quadratic equation has two real solutions.
This is because the quadratic formula, which gives the solutions of the quadratic equation, involves the square root of the discriminant.
Since the discriminant is positive, the square root is a real number, resulting in two distinct real solutions.
If the discriminant is negative (b² - 4ac < 0),
The square root of the discriminant is an imaginary number since it involves a negative integer's square root.
Given that the discriminant is a component of the quadratic formula,
if it is negative, the quadratic formula will include computing the square root of a negative integer, which is not a real number.
This is due to the fact that solving the quadratic equation requires obtaining the square root of the discriminant, and a negative square root is not a real integer.
In conclusion, there are no actual solutions to a quadratic equation with a negative discriminant since the solutions entail calculating the square root of a negative.
When the discriminant is zero,
it means that the quadratic equation has only one solution, which is a real number.
This is because the quadratic formula for finding the solutions of the quadratic equation reduces to a simpler formula when the discriminant is zero. Specifically,
The quadratic formula becomes,
x = -b/2a This formula gives us the only solution of the quadratic equation when the discriminant is zero.

f(-3)=-2*9+1
f(-3)=-18+1
f(-3)=-17
The value of the function f(t)=-2t²+ 1 for f(-3) will be - 17.We can find the value of f(-3) by putting -3 at the place of t
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range. In mathematics, functions serve as the fundamental building blocks for developing technology.
It is given that the function is,
f(t)=-2t²+ 1
We have to find the value of the function as t=-3.
We can find the value of f(-3) by putting -3 at the place of t and applying the arithmetic operation as,
f(t)=-2t²+ 1
f(-3)=-2(-3)²+1
f(-3)=-2(9)+1
f(-3)=-18+1
f(-3)= -17
Thus, the value of the function f(t)=-2t^2+ 1 for f(-3) will be -17. We can find the value of f(-3) by putting -3 in the place of t.

The robber stole only 25 pounds of quarters out of the coin machine. Quarters are weighed in ounces. If there are 16 ounces in 1 pound, how many ounces of quarters were stolen?
Answers
Answer:
400 ounces
Step-by-step explanation:
x pound(s) = (16*x) ounces
25 pounds=(16*25) ounces
25 pounds= 400 ounces
400 ounces of quarters were stolen.
Given,
The robber stole only 25 pounds of quarters out of the coin machine. Quarters are weighed in ounces.
If there are 16 ounces in 1 pound.
We need to find out how many ounces of quarters were stolen.
How many ounces in 1 pound?16 ounces = 1 pound
Find how many pounds of quarters were stolen.
= 25 pounds of quarters.
Convert 25 pounds of quarters into ounces of quarters.
1 pound = 16 ounces
Multiplying 25 on both sides.
25 x 1 pound = 25 x 16 ounces.
25 pounds = 400 ounces.
This means 25 pounds of quarters is 400 ounces of quarters.
Thus 400 ounces of quarters were stolen.

To solve for this problem, we want to isolate x on one side of the equation.
Apply the distributive property on the right side:
[tex]3x - x - 5 = 2x+4 -9[/tex]
Combine like terms:
[tex]2x - 5 = 2x - 5[/tex]
Woah, we have the exact same thing on both sides of the equation. This means that we have infinite solutions, aka any value of x will satisfy this equation.
Test it out! Any value of x, whether its 1, 5, or 10000 will satisfy the equation.
So this has infinite solutions.
