30% of 50
what’s the easiest and fastest way to solve it?
Answers
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:
change the percent to a decimal
30% to .30
.30 x 50= 15

Evaluate the expression 6 + 4 x {3+7}.
Answers
Answer:
46
Step-by-step explanation:
6 + 4 x {3+7} [B.O.D.M.A.S rule] (First bracket)
= 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.

Find the y intercept of the following line (-2,1) and (1, 2.5)
Answers
Answer:
2
Step-by-step explanation:
(-2 , 1) ; (1, 2.5)
Slope = [tex]\frac{y_{2}-y_{1}}{x_{2}-x_{1}}\\[/tex]
[tex]\frac{2.5-1}{1-[-2]}\\\\= \frac{1.5}{1+2}\\\\=\frac{1.5}{3}\\\\= 0.5[/tex]
m =0.5
y -y1 =m(x -x1)
y - 1 = 0.5(x - [-2])
y - 1 = 0.5(x + 2)
y -1 = 0.5x + 0.5*2
y - 1 =0.5x + 1
y = 0.5x + 1 + 1
y = 0.5x + 2
y-intercept = 2

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

Answers
Answer:
He must pay $129.45 and the total amount due is $3,629.45.
