Answer

The answer is negative 14.

Step-by-step explanation:

When you add a negative by a negative it equals a negative. Like if you add 1 + 1 it's going to equal 2 which is a positive, not a negative. So the answer is technically 8 + 6 which is 14 and all you have to do is add a negative sign.

step 2. A = 2(3/4) = 3/2 1-1/2.

step 3. B = 1-3/4(1/2) = 7/4(1/2) = 7/8

step 4. C = 1(2) = 2

step 5. D = 2-1/2(1/2) = 5/2(1/2) = 5/4 = 1-1/4.

Sally puts $2,500 in a bank account. She takes it out 10 years later and with interest, now has $4,100. What is the percent change?

Answers

Answer:

64%

Step-by-step explanation:

Find the percent change by finding the difference between the amounts, then dividing it by the original amount

(4,100 - 2,500) / 2,500

1600 / 2500

= 0.64

So, the percent change is 64%

What percent of 120 is 42?
can you show your work, please

Answers

Solution for 42 is what percent of 120:

42:120*100 =

(42*100):120 =

4200:120 = 35

Now we have: 42 is what percent of 120 = 35

Question: 42 is what percent of 120?

Percentage solution with steps:

Step 1: We make the assumption that 120 is 100% since it is our output value.

Step 2: We next represent the value we seek with $x$x​.

Step 3: From step 1, it follows that $100\%=120$100%=120​.

Step 4: In the same vein, $x\%=42$x%=42​.

Step 5: This gives us a pair of simple equations:

$100\%=120(1)$100%=120(1)​.

$x\%=42(2)$x%=42(2)​.

Step 6: By simply dividing equation 1 by equation 2 and taking note of the fact that both the LHS
(left hand side) of both equations have the same unit (%); we have

$\frac{100\%}{x\%}=\frac{120}{42}$
100%
x%​=
120
42​​

Step 7: Taking the inverse (or reciprocal) of both sides yields

$\frac{x\%}{100\%}=\frac{42}{120}$
x%
100%​=
42
120​​

$\Rightarrow x=35\%$⇒x=35%​

Therefore, $42$42​ is $35\%$35%​ of $120$120​.
It’s 35%

42/120 = 0.35

0.35 x 100 = 35%

Step-by-step explanation:

Answer:

-7/12

Step-by-step explanation:

-1/3 - 1/4 becomes -4/12 - 3/12

this is because 12 is the common denominator for both fractions. then subtract the numerators because when you add or subtract fractions, the denominator stays the same.

-4 - 3 = -7

the answer is

-7/12

the answer cannot be simplified so it remains the same

Use the following function rule to find f(12). f(x)=10x-4, f(12)=

Answers

f(x)=10x-4, f(12)= 116

The value of the function f(x) = 10x - 2 at f(12) is 114.

What is a function?

A function can be defined as the outputs for a given set of inputs.

The inputs of a function are known as the independent variable and the outputs of a function are known as the dependent variable.

Given, A function f(x) = 10x - 4.

To find f(12) we have to replace x with 12 in the function f(x).

∴ f(12) = 10(12) - 4.

f(12) = 120 - 4.

f(12) = 114.
