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 the number of accurate answers provided by Tom equal x.
The number of incorrect responses is ten.
Tim receives 4 marks for each right answer.
Marks deducted for wrong answers = 0.
Total Points = 76
When all of the above statements are combined, the equation
76 = 4 x + 10 * 0
4 x = Equals 76.
19 = x
The number of correct answers is 19
The number of incorrect responses equals ten.
Total number of questions = 19 + 10 = 29

Answer:
x = 7
Step-by-step explanation:
Step 1: Add 6 to both sides.
[tex]3x - 6 + 6 = 15 + 6[/tex] [tex]3x = 21[/tex]Step 2: Divide both sides by 3.

Which line on the graph below has an undefined slope?
Line R has the undefined slope
Answer:
C/R
Step-by-step explanation:
write the equation of the graph in slope intercept form
(3,-3) (-3,-5)
m= -4
Answer:
y = -4x + 9
Step-by-step explanation:
Slope intercept form is:
y = mx + b
If m = -4
y = -4x + b
Plug the values of the first set of coordinates into this:
y = -4x + b
-3 = -4(3) + b
-3 = -12 + b
Add 12 to both sides of the equation to isolate b:
-3 + 12 = -12 + b + 12
9 = b
So that makes the slope intercept form:
y = -4x + 9

Cries In didn’t pay attention in class in my lower grades
Use the figure to find the measures of the numbered angle.
Answer:
angle 1 = 61°
angle 2 = 119°
angle 3 = 61°
angle 4 = 119°
angle 5 = 119°
angle 6 = 61°
angle 7 = 119°
Step-by-step explanation:
angle 1 = 61° (corresponding angles are always equal)
angle 1 + angle 2 = 180° (linear pair)
=> 61° + angle 2 = 180°
=> angle 2 = 180° - 61° = 119°
angle 2 = 119
angle 1 = angle 3 = 61° (vertically opposite angles are equal)
angle 2 = angle 4 = 119° (vertically opposite angle are equal)
angle 4 = angle 5 = 119° (interior opposite angles are equal)
angle 6 = 61° (vertically opposite angles are equal)
angle 5 = angle 7 = 119° (vertically opposite angles are equal)
Hope it helps :)

Which fraction is close to zero?
a. 5/12 b. 8/12 c. 2/12 d. 4/6
Answer:
2/12
Step-by-step explanation:
Answer:
C) 2/12
Step-by-step explanation:
You need to convert the fractions to decimals (by dividing the top number by the bottom number).
5/12 = 0.416...
8/12 = 0.666...
2/12 = 0.166...
4/6 = 0.666...
As you can see, 2/12 in decimal form is closer to 0 than the other fractions.
A sprinter travels a distance of 100 m in a time of 8.96 seconds.
What is the sprinter's average speed rounded to 4 sf
The average speed is 40.176 Km/h.
What is Average speed?The average speed is the total distance traveled by the object in a particular time interval.
Given:
distance = 100m
time= 8.96 seconds
So,
average speed = distance/time taken
= 100/8.96
= 11.16 m/s
and in Km/h
= 11.16* 18/5
= 40.176 Km/h
Hence, the average speed is 40.176 Km/h.

Victor and his friends are preparing for an epic snowball fight. They make 85 snowballs before Victor's dad calls them in for lunch. After lunch, they make more snowballs. In all, Victor and his friends make 153 snowballs.
Which equation can you use to find the number of snowballs s Victor and his friends make after lunch?
Answer:
85+x=153
Step-by-step explanation:
So basically, Victor made an unknown amount of snowballs after lunch, and you need to find the amount. You can represent the unknown as the variable x. Then, you get the equation 85+x=153
The equation used to find the number of snowballs s Victor and his friends make after lunch is s + 85 = 153.
Given data:
Victor and his friends are preparing for an epic snowball fight. They make 85 snowballs before Victor's dad calls them in for lunch. After lunch, they make more snowballs. In all, Victor and his friends make 153 snowballs.
Now , the equation to find the number of snowballs Victor and his friends make after lunch is determined as :
s + 85 = 153
In this equation, "s" represents the number of snowballs they make after lunch. The equation states that the sum of the snowballs made before lunch ("85") and the snowballs made after lunch ("s") is equal to the total number of snowballs they made ("153").
Hence, the equation is s + 85 = 153

An auto mechanic earns $498.75 in 35 hours during the week. His pay is $2.50 more per hour on weekends. If he works 6 hours on the weekend in addition to 35 hours during the week, how much does he earn?
Plz show work and i will be so grateful
Answer:
35 hours during week pay: 498.75
2.50 more on weekends
Lets us find unit rate

square root both sides and get,
x= 12
and
x= (-12)
remember to put your negative and 12 into parenthesis because you are multiplying the negative as well.
Answer:
x = 12
x = -12

Step 1: Take the square root of both sides.
[tex]\sqrt{x^2} =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x =[/tex] ± [tex]\sqrt{144}[/tex] [tex]x = 12[/tex] or [tex]x = -12[/tex]Therefore, x = 12 and x = -12 are the answers.

-22
m=⅓
m=-3
m=3
m=-⅓
Answer: Slope of the line formed by the data is -3.
m=-3 for y=mx+b.
Step-by-step explanation: The slope is the change in y (the rise) divided by the change in x (the run) between two points on the line. I'll pick 2 points: (-4,17) and (9,-22). Any two points will work, if it is a straight line. For these points, y, the rise, changes from 17 to -22, for a net change of (-22 - 17) = -39 for y. x, the run, goes from -4 to 9, for a change in x of (9 - (-4)) = 13.
The rise(y) over the run(x) for these points is thus (-39/13) = -3
The slope is -3

HELP ASAP PLS
Answer:
inconsistent, none
Step-by-step explanation:
Write both equations in slope-intercept form to see if the lines are parallel.
These two lines have slope m = −2 and different y-intercepts, therefore they are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
The system of equations 4x + 2y = −8 6x + 3y = 9 is inconsistent and has no solutions.
What is system of Equations?A system of equations is a collection of two or more equations with a same set of unknowns.
We need to write both equations in slope-intercept form to see if the lines are parallel.
4x+2y=-8
2y=-8-4x
y=-4-2x,
y=-2x-4, m₁=-2
and 6x+3y=9
3y=9-6x
y=-2x+3, m₂=-2.
So two lines have slope m = −2 and different y-intercepts,
It means two line are parallel.
Since the lines are parallel, the system is inconsistent and there are no solutions.
Hence 4x + 2y = −8 , 6x + 3y = 9 is inconsistent and has no solution.
