Answer:

<h3>Answer: 46</h3>

Step-by-step explanation:

percentage scored = 92

number of correct question = x

total number of questions = 50

The formula for calculating the percentage scored

= number of correct question / total number of questions x 100

That is

92 = \frac{x}{50}

50

x

x \frac{100}{1}

1

100

92 = \frac{100x}{50}92=

50

100x

cross multiplying :

100x = 92100x=92 x 5050

100x = 4600100x=4600

dividing through by 100 , we have

<h3>x = 46x=46</h3>

Therefore, she got 46 questions right

Step-by-step explanation:

Basically 100% means she scored all 50 question correct.

Solution:

100% = 50 questions

1% = 50÷100 = 0.5

92/100 x 50 = 46

Answer: 46

4(PX+1)=64 what is the value of x in terms of p and what is the value of x when p is -5 ?
Oksana_A [137]

Answer:

x = -3

Step-by-step explanation:

4(PX+1)=64\\\\p= -5

Substitute -5 for p in the given equation and solve

4(-5(x)+1)=64\\\\\mathrm{Divide\:both\:sides\:by\:}4\\\frac{4\left(-5x+1\right)}{4}=\frac{64}{4}\\\\Simplify\\-5x+1=16\\\\\mathrm{Subtract\:}1\mathrm{\:from\:both\:sides}\\-5x+1-1=16-1\\\\Simplify\\-5x =15\\\\\mathrm{Divide\:both\:sides\:by\:}-5\\\frac{-5x}{-5}=\frac{15}{-5}\\\\Simplify\\x = -3

If f(x)=2x+7 and g(x)=11x-4, find (f+g)x.
klemol [59]

Answer:

(f+g)(x) = 13x + 3

Step-by-step explanation:

Rewrite  f(x)=2x+7 and g(x)=11x-4 in columns, as follows:

f(x)=2x+7

+g(x)=11x-4

----------------

Now add each column separately.

f(x)+g(x) = (f+g)(x) ("the sum of functions f and g")

2x + 11x = 13x, and, finally, 7-4 = 3.


Therefore,

 f(x)=2x+7

+g(x)=11x-4

----------------

(f+g)(x) = 13x + 3
