Answer 1

Answer: 3

Step-by-step explanation:

f(x)= -x + 4

Therefore f(-1)= -(-1)+4= 1+4= 5

h(x)= (3/2)x - 1

Therefore h(2)= (3/2)(2) -1= 3-1= 2

f(-1) - h(2)= 5 - 2= 3

12 less than 7 times a number, how do I put this in numbers and symbols and letters

Answers

Answer:

7x - 12

Step-by-step explanation:

'12 less' means thats u have to subtract 12 from the next number

'7 times a number' means 7 multiplied by a variable like x, y, or z

you put those two together and get 7x - 12

Answer: 7x-12

Step-by-step explanation:

“12 less than” would simply imply “subtract 12 from” the sum of 7 times a number. Let “x” represent the unknown number and multiply it by 7.

bus driver drove from Philadelphia to Washington D.C. He drove the first 100 km in 2 hours, the next 55 km in 1 hour, and the final 75 km in 2 hours. What is the average speed of the bus throughout the trip?

Answers

Answer: 112, 68, 22, 90

Step-by-step explanation:

This is fairly somewhat easy

since the adjacent side of 1 is 68 degrees

then 1 would be 112 degrees to make it supplementary to 180 degrees

angle 3 is vertical of angle 68

making it 68 degrees

angle 5 is given to be 90 degrees meaning angle 4 is inbetween

angles 3 and 5 so ( 68 and 90 ) that'll add up to 158 meaning angle 4

is 22

angle 1 = 112

angle 3 = 68

angle 4 = 22

angle 5 = 90

13x = 3(X-20) How to solve this algebra equation?

Answers

-6x is the correct answer

Answer:

x = -6

Step-by-step explanation:

13x = 3(x - 20)              {Use distributive method:a(b+c)=(a*b) + (a*c)

13x = 3*x - 3*20

13x = 3x - 60            {Subtract '3x' from both sides}

13x -3x = -60      

    10x = -60      {Divide both sides by 10}

        x= -60/10

       x = -6

30% of 50

what’s the easiest and fastest way to solve it?

Answers

Step 1: Our output value is 50.

Step 2: We represent the unknown value with $x$.

Step 3: From step 1 above,$50=100\%$.

Step 4: Similarly, $x=30\%$.

Step 5: This results in a pair of simple equations:

$50=100\%(1)$.

$x=30\%(2)$.

Step 6: By dividing equation 1 by equation 2 and noting that both the RHS (right hand side) of both
equations have the same unit (%); we have

$\frac{50}{x}=\frac{100\%}{30\%}$

Step 7: Again, the reciprocal of both sides gives

$\frac{x}{50}=\frac{30}{100}$

$\Rightarrow x=15$

Therefore, $30\%$ of $50$ is $15$

Answer:

15

Step-by-step explanation:

= 6 + 4 × 10. (Then Multiplication)

= 6 + 40. ( At last addition)

= 46 (Ans)

The simplified value of the expression  6 + 4 × {3 + 7} is 100.

What is PEMDAS rule?

PEMDAS rule states the correct order of simplifying an expression is as follows -: Parenthesis, exponents, multiplications, divisions, additions, and, subtractions.

Given, An expression 6 + 4 × {3 + 7}.

First, we'll add 6 and 4 as 3 and 7 are inside curly brackets,

not in parentheses.

Therefore,

6 + 4 × {3 + 7}.

= 10 × {3 + 7}.

Now, we can either distribute the terms or take the addition and multiply.

= 10 × 10.

= 100.

Therefore if a system is already at half charge (t1/2 seconds after starting) then after t1/2 more seconds the system will be charged to 50% plus half of 50%. That is 25% more, or 75% of the entire charge. Let's say that four t1/2's have gone by. That means that the charge (or voltage) is at (50% + 1/2*50% + 1/2*1/2*50% + 1/2*1/2*1/2*50%) = 93.75% of maximum charge. Yikes!
