Answer:
y = -15/8 + x/8
Step-by-step explanation:
x - 8y = 15
Solve for y.
Subtract x from both sides of the equation - -8y = 15-x
Divide -8 from both sides of the equation - y= -15/8 + x/8
(The negative from the x and 8 cancel out and become positive)
Answer:
y=x-15/8
Step-by-step explanation:
Subtract x from both sides
Divide both sides by −8.
Dividing by −8 undoes the multiplication by −8.
Divide 15−x by −8.

-5 (-1 + 6)need help
Answer:
-25
Step-by-step explanation: When you multiply to negatives together you get a positive thus being shown in the problem -5 times -1 =5 then you multiply 6 times -5 and whenever you multiply a positive number by a negative you'll always get a negative number so 6 times -5 =-30 then you add 5 and -30 and you get -25. I hope this is right :D
In 2010, 465 students went to a certain school. In 2014, 372 students went to the same school by what percent did the number of students decrease
Answer:
20% decrease
Step-by-step explanation:
New value =
465 - Percentage decrease =
465 - (20% × 465) =
465 - 20% × 465 =
(1 - 20%) × 465 =
(100% - 20%) × 465 =
80% × 465 =
80 ÷ 100 × 465 =
80 × 465 ÷ 100 =
37,200 ÷ 100 =

write as an equation and solve: when 4 is added to the number that is produced by three times the number p, the result is equal to 25.
Answer:
3p+4=25
Step-by-step explanation:
3p+4=25
Answer:
Equation is 3p+4=25p=7Step-by-step explanation:
Isolate the variable
3p + 4 - 4 = 25 - 4
Simplify
3p = 21
Solve for p
3p/3 = 21/3
p=7

C. 144 inches
D. 2 feet
The perimeter of a chalkboard is 16 feet. The area is 15 square feet. What are the dimensions of the board
Answer:
5 by 3
Explanation:
15 = 5 x 3
16 = 5 + 5 + 3 + 3
The dimensions of the board is either 5 by 3 square inches or 3 by 5 square inches.
What is a rectangle?The rectangle is 4 sided geometric shape whose opposites are equal in lengths and all angles are about 90°.
here,
let the length of the board be x, and width be w,
The perimeter of the rectangle board = 16
2 (l + w) = 16
l + w = 8
l = 8 - w
Now,
area of the board = 15
l × w = 15
(8 - w)w = 15
8w - w² = 15
w² -8w + 15 =0
(w - 3)(w -5) = 0
So,
w = 3 or 5
Now,
Lengths = 8 - 3 or 8 - 5
= 5 or 3
Thus, the dimension of the board either 5 by 3 square inches or 3 by 5 square inches.

Angle Measurements
Identify the relationship (complementary, linear pair/supplementary, or vertical) and find the
value of x in the image below.
(3x + 10)
47°
Answer:
X = 11
Complementary angles
Step-by-step explanation:
Complementary angles are when two angles add up to 90 degrees.
3x + 10 + 47 = 90
3x + 10 = 43
3x = 33
x = 11

Write an equation that approximates the depth y of water in the aquarium x weeks after you fill it.
Answer:
y = -2x + 22
Step-by-step explanation:
You fill an aquarium with water, the water is 22 inches deep. The water evaporates at 2 inches per week. Write an equation that approximates the depth y of water in the aquarium x weeks after you fill it.
Answer: The problem above represents that of a linear function. The equation of a linear function is given by:
y = mx + b, where y is the dependent variable, x is the independent variable, m is the rate of change and b is the initial value of y when x = 0.
From the problem, the independent variable is the number of weeks and the dependent variable is the depth of water, hence y = depth of water and x = weeks after you fill it.
The rate = 2 inches per week, since it evaporates (decreases), hence m = rate of change = -2. Also, at 0 weeks (x = 0), the depth (y) = 22 inches, therefore b = 22. Using the equation for linear function, we get:
y = -2x + 22
Decide whether the given ordered pair is a solution of the system.
x+y=5
X-y= 3
; (4,1)
Is the given ordered pair a solution to the given system?
A. Yes, because (4,1) makes both equations true.
B. No, because (4,1) makes neither equation true.
C. No, because (4,1) only makes the equation x + y = 5 true.
D. No, because (4,1) only makes the equation x-y = 3 true.
Answer:
A. it is true for both equations
Step-by-step explanation:
x = 4 and y = 1
sub these values into the equations
4 + 1 = 5
4 - 1 = 3
