Answer: [tex]y=5.666667[/tex] or [tex]y=5 \frac{6}{9}[/tex] in fraction
Step-by-step explanation:
1. Simplify -9.8-y+2.8y to -9.8+1.8y
0.4=-9.8+1.8y0.4=−9.8+1.8y
2. Regroup terms
0.4=1.8y-9.8
3. Add 9.8 to both sides.
0.4+9.8=1.8y
4. Simplify 0.4+9.8 to 10.2
10.2=1.8y
5. Divide both sides by 1.8
[tex]\frac{10.2}{1.8} =y\\[/tex]
6. Simplify [tex]\frac{10.2}{1.8\\}[/tex] to 5.666667
5.666667 = [tex]y[/tex]
7. Switch sides.
[tex]y=5.666667[/tex]

Write an equation of the line with a slope of -3/4 and y-intercept of -6
Answer:
Hi there!
Your answer is:
y= -3/4x -6
Step-by-step explanation:
The y int is the constant.
The slope is the coefficient of the X
Hope this helps!
The equation of the line with a slope of -3/4 and y-intercept of -6 is; 4y + 3x = -24.
The slope-intercept form of the equation of a straight line usually takes the form;
y = Mx + cwhere; m = slope and c = y-intercept
Therefore; the equation of the required line is;
y = (-3/4)x + (-6)4y = -3x - 244y + 3x = -24Read more;

A student works for 80 hours each month and plans to work for 5 hours each day, but only on days when scheduled to work. The function / (d) - 80 -- 5d represents the number of
hours of work remaining for the month after working for d days.
Which statement is true?
A. The value of (4) is 20, and it represents the number of hours of work remaining for the month after working for 4 days.
B. The value of ? (4) is 20, and it represents the number of hours spent working over 4 days
C. The value of }(4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
D. The value of (4) is 60, and it represents the number of hours spent working over 4 days.
**pls help ASAP taking a test .
Answer:
C. The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Step-by-step explanation:
So 5 time 4 equals 20...!
80 minus 20= 60
The value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days, which is the correct answer would be option (C).
What is a numerical expression?A numerical expression is algebraic information stated in the form of numbers and variables that are unknown. Information can is used to generate numerical expressions.
A student works 80 hours per month and plans to work 5 hours each day, but only on days when work is planned. After working for d days, the function / (d) - 80 — 5d shows the number of hours of work remaining for the month.
⇒ f (d) = 80 - 5d ....(i)
According to option (C),
Substitute the value of d = 4 in equation (i),
⇒ f (4) = 80 - 5(4)
⇒ f (4) = 80 - 20
⇒ f (4) = 60
Thus, the value of f (4) is 60, and it represents the number of hours of work remaining for the month after working for 4 days
Hence, the correct answer would be option (C).

Santa Claus has been experiencing some recent back pain and is unable to carry large bags of toys over his shoulders. As a result he uses redex to deliver many of his gifts this year. Fedex charges a flat rate of $2.50 plus $0.85 per pound. If the cost of sending gifts to the Jones is $28.85, how much did their gifts weigh?
Answer: 31 pounds
Step-by-step explanation:
From the question, we are informed that Fedex charges a flat rate of $2.50 plus $0.85 per pound and that the total cost of sending gifts to the Jones is $28.85. This can be mathematically expressed as:
2.50 + 0.85p = 28.85
where p = weight of the gift
So we have to solve the equation
2.50 + 0.85p = 28.85
0.85p = 28.85 - 2.50
0.85p = 26.35
p = 26.35/0.85
p = 31
Therefore the weight of the gift is 31 pounds

Alexandra has 36 coins valued at $6.00. She has only nickels and quarters. Which equation can be used to solve for the number of nickels, n?
0.05n + 0.25(36 – n) = 6
0.05n + 0.25(36 – n) = 36
n + 0.05 = 0.05n
n + (36 – n) = 36
Answer:A
Step-by-step explanation:
Answer:
Let n be the number of nickels and q be the number of quarters, then
n + q = 36 . . . (1)
0.05n + 0.25q = 6 . . . (2)
From (1): q = 36 - n . . . (3)
Putting (3) into (2) gives:
0.05n + 0.25(36 - n) = 6

What is percentage of a number?The percentage of a number represents a portion or fraction of the whole number expressed as a fraction of 100. It is often used to describe a proportion or rate out of 100.
To calculate the percentage of a number, you typically multiply the number by the desired percentage as a decimal or fraction. The result represents the portion or fraction of the number expressed as a percentage.
The formula for calculating the percentage of a number is:
Percentage = (Number * Percentage Value) / 100.
Substituting the values into the formula above;
percentage = (9 / 12) * 100
percentage = (3/4) * 100
percentage = 0.75 * 100
