Simplify the expression -6w + (-8) + 1 + (-7w)
Answer:
The expression in simplified form is -13w - 7
Step-by-step explanation:
Given expression is;
-6w + (-8) + 1 + (-7w)
Rearranging the expression and combining alike terms;
-6w + (-7w) + (-8) + 1
-6w - 7w -8 + 1
-13w - 7
The expression in simplified form is -13w - 7
Hence,
The expression in simplified form is -13w - 7

Cailen has 2 hours to drive to her friend’s house and work on some assignments. Each assignment takes an average of 18 minutes, and it takes Cailen 10 minutes to drive to the house. What inequality describes this? How many assignments can Cailen complete?
Answer:
Cailen can complete at least 6 assignments.
Step-by-step explanation:
Given that:
Time Cailen have = 2 hours = 2*60 = 120 minutes
Time taken to drive to house = 10 minutes
Time left for assignments = 120 - 10 = 110 minutes
Time taken on one assignment = 18 minutes
Let,
x be the number of assignments.
18x + 10 ≤ 120
18x ≤ 120-10
18x ≤ 110
Dividing both sides by 18
[tex]\frac{18x}{18}\leq \frac{110}{18}\\x\leq 6.11[/tex]
Hence,
Cailen can complete at least 6 assignments.

How does the graph of f (x) = |x| compare with the graph of g (x) = -1/2 |x|?
Answer:
The graph of f(x) = |x| is a v-shape and doesn't cross over the x-axis.
The graph of g(x) = -1/2|x| is still a v-shape, but it's upside-down and a bit wider. This is because of the coefficient in front of the |x|. The negative sign flips the graph of |x| and the 1/2 makes the slope smaller, therefore the graph is less steep.

What is the solution to the linear equation? d – 10 – 2d + 7 = 8 + d – 10 – 3d
Answer:
d = 0.33
Step-by-step explanation:
First off, you want to get like terms next to each other. We'll move the numbers with variables on one side and normal numbers on the other. Since we're changing the sides of the equal sign they're on, this also changes whether their positive or negative.
d - d - 2d + 3d = 10 -7 + 8 - 10
Now that they're together, we can add or subtract them. The variables without numbers can be ones for this equation.
3d = 1
Now we divide 1 by 3 to find what d equals.
3d/3 = 1/3
d = 0.33
What is the direct variation equation if f(x) varies directly with x and f(x)=−18 when x = 3?
A) f(x)=−15x
B) f(x)=−3x
C) f(x)=−16x
D) f(x)=−6x
Answer:
your answer is B becausewe can find k when given any point by dividing the y-coordinate by the x-coordinate. For example, if y varies directly as x, and y = 6 when x = 2, the constant of variation is k = - 3.
Answer:
The answer is C, I just took the quiz in CAVA :))
FYI: C is f(x)=−1/6x not f(x)=−16x
Julain has 200ml of 35% hand sanatizer. Sarah has 150ml of 85% hand sanatizer. They mix the sanatizers together in an effort to acheive 60% concentration. 1) How many milliliters of pure alchol are in the new mixture? 2) How many mililliters of water are in the new mixture? 3)What is the concentration of alchol in the new mixture?(Round your answer to one decimal place)
Answer:210ml, 140 ml, 60%
Step-by-step explanation:
Given
Juli has 200 ml of 35% hand sanitizer
Sarah has 150 ml of 85% hand sanitizer
The mixture has 60% con. i.e. 60 % is Alcohol and 40 % water
The final volume of the mixture =200+150=350 ml
Now, 60% of 350 ml= [tex]350\times 0.6=210\ ml[/tex]
So, pure Alcohol is 210 ml
Water in the final mixture= [tex]350\times 0.4=140\ ml[/tex]
The concentration of Alcohol is 60%
A helicopter flies 240 miles in 2 hours 30 minutes.
Calculate the average speed, in mph, of the helicopter.
Answer:
96 mph is the answer
The average speed is 96 mph
What is Average speed?The average speed is the total distance traveled by the object in a particular time interval.
Given:
d= 240 miles
t = 2 hours 30 minutes.
t= 2.5 hours
Average speed= distance/ time
= 240/2.5
= 96 mph

Step-by-step explanation:
2 = f/8 Solve the equation.
Answer:
f = 16
Step-by-step explanation:
Isolate the variable, f. Note the equal sign, what you do to one side, you do to the other. Multiply 8 to both sides of the equations:
2 = (f/8)
2(8) = (f/8)(8)
f = 2 * 8 = 16
f = 16 is your answer.

Answer:
f= 16
Step-by-step explanation:
multiply by 8 on both sides

When Pico writes articles for an adventure magazine, he gets paid by the word. For a 1,300-word article, he earned $780. How much would Pico earn for a 1,950-word article?
Answer:
Earning for 1950- word article = $1170
Step-by-step explanation:
Given that:
Amount paid for 1300 word article = $780
Ratio of words to money = 1300 : 780
Let,
x be the amount for 1950 words.
Ratio of words to money = 1950 : x
As the relationship is proportional
1300 : 780 :: 1950 : x
Product of mean = Product of extreme
780 * 1950 = 1300x
1300x = 1521000
Dividing both sides by 1300
[tex]\frac{1300x}[1300}=\frac{1521000}{1300}\\x=1170[/tex]
Hence,
Earning for 1950- word article = $1170

The distance between Maritza's house and her school is 12.5 kilometers. The bus stop is 11.75 kilometers from school. How many meters must she walk to the bus stop?
Answer: She must walk 750 meters to bus stop.
Step-by-step explanation:
Given: Distance between Maritza's house and her school (A)= 12.5 kilometers. (Total distance)
Distnance between Bustop and school (B)= 11.75 kilometers
Distance she need to walk to reach bus stop = A - B
= 12.5 - 11.75 kilometers
= 0.75 kilometers
= 0.75 x 1000 meters [ 1 kilometer = 1000 meters]
= 750 meters
Hence, She must walk 750 meters to bus stop.
