HELP DUE IN 10 MINUTES Two step equations word problems

Tim answered all the questions on his math test but got 10 answers wrong. He received 4 points for every correct answer, and there was no penalty for wrong answers. His score was 76 points.

1. Write an equation to determine the total number of questions (q) on Tim's math test.

2. Find the total number of questions on his math test.

Let number of answers correctly given by Tom = x

Number of Incorrect answers = 10

Marks given to Tim for every correct answer = 4 Marks

Marks for incorrect answer= 0

Total Score = 76

The equation , when all the above statement are combined together

→4 x + 10 × 0 = 76

→ 4 x = 76

x = 19

Number of Right Answers = 19

Number of Wrong Answer= 10

Total Question = 19 + 10= 29

1. q = (76 ÷ 4) + 10

2. 29

Step-by-step explanation:

1. You want to do the number of correct answers + the number of wrong answers: q = (76 ÷ 4) + 10

2. Find the number of correct answers by doing 76 ÷ 4 = 19. Then add the number of wrong answers 10, 19 + 10 = 29

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.

the polynomial is a perfect square trinomial of the form a^2-2ab+b^2:

option a. true

step-by-step explanation:

9x^2-12x+4

comparing with the form a^2-2ab+b^2

1.) a^2=9x^2

solving for a: square root both sides of the equation:

sqrt(a^2)=sqrt(9x^2)

a=sqrt(9) sqrt(x^2)

a=3x

2.) b^2=4

solving for b: square root both sides of the equation:

sqrt(b^2)=sqrt(4)

b=2

to be a perfet square trinomial 2ab must be equal to 12x. let's check:

2ab = 2 (3x) (2)

2ab = 12x

correct
