Answer:
I times the 12 by 5 and divided by 2 and subtract by 12
I get 18 and I thought it is 18
Answer:
Step-by-step explanation:
If a fair dice is rolled 6 times, 2/6 times the number would be greater than 4
If rolled 12 times, then 4/12 times the number would be greater than 4
4/12 = 1/3
Rearrange the formula c=4/a-b to make a the subject
Answer:
[tex] a = \dfrac{4 - bc}{c} [/tex]
Step-by-step explanation:
c = 4/(a - b)
Multiply both sides by a - b.
c(a - b) = 4
ac + bc = 4
ac = 4 - bc
a = (4 - bc)/c

Write an absolute value equation that has the solutions x = -6and x = 10
During the school year, each student planted
1.2 x 10^2 flowers as part of a community
service project. If there are 1.5 x 10³
students in the school, how many flowers did
they plant in total?
Answer:
180000 total flowers
Step-by-step explanation:
1.2 × 10² = is the amount of flower for each student
1.5 × 10³ = is the total of students in school
Amount of flower × total student = total flowers
(1.2 × 10²) × (1.5 × 10³)
120 × 1500
= 180000

|x| < 4
Answer:
Image 2: a segment from -4 to 4 with the endpoints excluded (with empty circles).
Step-by-step explanation:
|x| < 4 means "the distance from x to 0 is less than 4". That means that any number bigger than -4 and smaller than 4 matches the inequality from the question.
Side note: Please start analyzing the absolute values as "distance from 0" and you'll be able to solve those questions yourself with less effort.

2(b + 5) = 3(b - 2) + 23
Answer:
b = -7
Step-by-step explanation:
2(b + 5) = 3(b - 2) + 23
2b + 10 = 3b - 6 + 23
10 + 6 -23 = 3b - 2b
-7 = b
Answer:
b = -7
Step-by-step explanation:
[tex]2(b+5) = 3(b-2) + 23[/tex]
for the left side of the equation: [tex]2*b + 2*5 = 2b + 10[/tex]
for the right side of the equation: [tex]3*b + 3*-2 = 3b - 6 + 23 = 3b + 17[/tex]
[tex]2b + 10 = 3b + 17[/tex]
to isolate b, subtract 2b from both sides
[tex]10 = b + 17[/tex]
subtract 17 from both sides
[tex]-7 = b\\b = -7[/tex]

Answer:
7.6
Step-by-step explanation:
[tex]\sqrt{(-3-4)^2 + (5-2)^2} \approx 7.6[/tex]
Evaluate the expression (2+5)4
Since the 2 + 5 is in parenthesis, we do that first.
7(4) =
7 * 4 = 28
Hey there!
Assuming:
(2 + 5)(4) or (2 + 5)^4
Simplifying:
(2 + 5)(4)
= 7(4)
= 28
Simplifying:
(2 + 5)^4
= (7)^4
= 7^4
= 7 * 7 * 7 * 7
= 49 * 49
= 2,401
We’re going to assuming equation #1 in our assumption as your question.
That being said, your answer is most likely: 28

Chad will have new carpet put on the rectangular floors of two rooms in his house. One floor is 12 1/2 feet long, and
the other floor is 15 3/4 feet long. Each floor has a width of 10 feet.
What is the total area in square feet of the new carpet?
A 125 ft²
B 157.5 ft²
©282.5 ft²
96.5 ft²
Answer:
c) 282.5 ft²
Step-by-step explanation:
Formula we use,
A = L × W
The area of one floor will be,
→ 12 1/2 × 10
→ 25/2 × 10
→ 250/2
→ 125 ft²
The area of another floor will be,
→ 15 3/4 × 10
→ 63/4 × 10
→ 630/4
→ 157.5 ft²
Total area of the new carpet is,
→ 125 + 157.5
→ 282.5 ft²
Hence, the total area is 282.5 ft².
If One floor is 12 1/2 feet long, and the other floor is 15 3/4 feet long. Each floor has a width of 10 feet. Then total area of new carpet is 282.5 ft²

Find the equation of the line that passes through (1,3) and is perpendicular to y = 2x + 3.
Leave your answer in the form ax + by = c Where a, b and c are integers.
The equation of the line that passes through (1,3) and which is perpendicular to y = 2x ₊ 3 is x ₊ 2y = 7.
Given the equation of the which passes through the point is (1,3)
the line is perpendicular to y = 2x ₊ 3
first we need to determine the slope of the equation.
line is perpendicular to y = 2x ₊ 3
perpendicular means slope (m) = ₋1
but given the in the line equation we have
y = mx ₊ c
m = 2
therefore ₋1 = 2
hence slope m = ₋1/2
Then the line passing through (1,3), substitute the coordinates of the point in the equation of the line:
y ₋ y₁ = m(x ₋ x₁)
take (1,3) as (x₁,y₁)
y ₋ 3 = ₋1/2 (x ₋ 1)
y ₋ 3 = ₋1x/2 ₊ 1/2
y ₋ 3 = ₋x ₊ 1/2
2y ₋ 6 = ₋x ₊ 1
2y ₊ x ₋ 6 ₋ 1 = 0
2y ₊ x ₋ 7 = 0
2y ₊ x = 7
x ₊ 2y = 7
which is in the form ax ₊ by = c
Hence we derived the equation of the line as x ₊ 2y = 7 which is in the form of ax ₊ by = c.

so 180-140= 40 degrees one of the missing angles in the triangle.
180 degrees is the full amount of degrees the angles of a triangle can equal.

2x+y = 3
x+y=1
Answer:
x = 2, y = -1
Step-by-step explanation:
Now change the equation,
→ x + y = 1
→ y = 1 - x
Then the value of x will be,
→ 2x + y = 3
→ 2x + 1 - x = 3
→ x = 3 - 1
→ [ x = 2 ]
Therefore, the value of x is 2.
Now value of y will be,
→ y = 1 - x
→ y = 1 - 2
→ [ y = -1 ]
Hence, the value of y is -1.

Do the points (15, -12), (28,14), and (32,21) all lie on the same line? Be sure you can explain why or why not.
Choosing different pairs of points we got different slopes, then we conclude that the 3 points don't lie on the same line.
Do the points lie on the same line?Remember that if a line contains two points (x₁, y₁) and (x₂, y₂), then the slope of the line is:
a = (y₂ - y₁)/(x₂ - x₁)
Here the 3 points are on the same line if we get the same slope for any pair that we choose.
If we use the first two; (15, -12) and (28, 14), the slope is:
a = (14 - (-12))(28 - 15) = 8.67
If we use the second and third point (28, 14) and (32, 21), we get:
a = (21 - 14)/(32 - 28) = 6.125
We got different slopes, then we conclude that the 3 points don't lie on the same line.

cubic inches ?
The size of the car engine in cubic inches is 263.6 2 cubic inches
How to determine the size of the car engine in cubic inches?The given parameters are
Volume = 4320 cubic centimeters
By general conversion rule, we have
1 cubic centimeter = 0.0610237 cubic inches
Multiply both sides of 1 cubic centimeter = 0.0610237 cubic inches by 4320
4320 * 1 cubic centimeter = 0.0610237 cubic inches * 4320
Evaluate the product
4320 cubic centimeters = 263.6 2cubic inches
Substitute 4320 cubic centimeters = 263.6 2cubic inches in Volume = 4320 cubic centimeters
