Solve for x. I have to show my work and no decimal answers. It's not mandatory, i just don't understand how to solve the problem. Someone pls help ;) & actually explain it.
Answer:
-22.5.
Step-by-step explanation:
Lets say that you meant w as the variable.
-4/3 w = 30.
To get rid of the 3, lets multiply 3 to both sides. We get:
3(-4/3 w) = 3(30)
We get:
-4w = 90.
To solve for the w, lets get rid of the -4 by dividing it from both sides.
(-4w)/-4 = 90/-4
We get:
w = -22.5

If three children equally share half loaf of bread among themselves, what fraction will each get?
Answer:
1/6 of the bread
Step-by-step explanation:
Given data
Let the amount of the loaf of bread be 1
But they are expected to share half
hence the amount to be shared is= 1/2 bread
The number of children is 3
Hence
=1/2/3
=1/2*1/3
=1/6 bread
Hence each child will get 1/6 of the bread

HELP PLS ITS ALGEBRA 1
Answer:
[tex] - \frac{2}{6} [/tex]
Step-by-step explanation:
Use distributive property to simplify both sides.
[tex] \frac{1}{6} (1 - 6x) = - \frac{1}{3} ( 6x + \frac{1}{2} )[/tex]
Use the Golden Rule of Algebra: (What we do to one side, we must do to the other).
[tex] \frac{1}{6 } - x = - 2x - \frac{1}{6} [/tex]
[tex] \frac{1}{6} = - x - \frac{1}{6} [/tex]
[tex] \frac{2}{6 } = - x[/tex]
[tex]x = - \frac{2}{6} [/tex]
Answer:
Step-by-step explanation:
[tex]\frac{1}{6}[/tex](1-6x) = - [tex]\frac{1}{3}[/tex](6x+[tex]\frac{1}{2}[/tex])
distribute in the fractions
[tex]\frac{1}{6}[/tex] - 1x = -2x - [tex]\frac{1}{6}[/tex]
subtract [tex]\frac{1}{6}[/tex] from both sides
-[tex]\frac{1}{6}[/tex]+[tex]\frac{1}{6}[/tex]-1x = -2x -[tex]\frac{1}{6}[/tex]-[tex]\frac{1}{6}[/tex]
-1x = -2x -[tex]\frac{2}{6}[/tex]
-x = -2x - [tex]\frac{1}{3}[/tex]
[tex]\frac{1}{3}[/tex] = -2x + x
[tex]\frac{1}{3}[/tex] = -x
- [tex]\frac{1}{3}[/tex] = x
x = - [tex]\frac{1}{3}[/tex]

A oil company has a large tank that holds the oil before it is distributed. If it costs $3.20 per cubic meter for oil, how much money would it cost to fill the entire tank?
A. $65,280
B. $68,000
C. $5,440
D. $67,200
Answer:
Option A, $65,280
Step-by-step explanation:
The volume of the tank is,
12×20×15+40×(50-15)×12
= 3600+16800
=20400 cubic meters
For each cubic meter, it costs $3.20, so for 20400 cubic meters it'll cost,
20400×$3.20
= $65,280

Answer:

Step-by-step explanation:
An angle measures 42.2° less than the measure of its complementary angle. What is the measure of each angle?
Answer:
x + (x-42.2) = 90
2x - 42.2 = 90
add 42.2 to both sides
2x = 132.2
divide each side by 2
x = 66.1
find the measure of the other angle
66.1 - 42.2 = 23.9
Step-by-step explanation:
Answer:
66.1° and 23.9°
Step-by-step explanation:
Complementary angles are angles that sum up to 90°
So equation : x + x - 42.2 = 90
2x - 42.2 = 90
2x = 132.2
x = 66.1
66.1° is the "other complementary angle"
This angle is 66.1 - 42.2 = 23.9°

Step-by-step explanation:
but a polygon ABCD might not be a rectangle if:
opposite sides of polygon ABCD are not of equal lengthsall angles of the polygon may not be right angles (90°)opposite sides may not be parallelFind the slope of the line that passes through (1, 2) and (8, 8).
Answer:
slope = [tex]\frac{6}{7}[/tex]
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (1, 2) and (x₂, y₂ ) = (8, 8)
m = [tex]\frac{8-2}{8-1}[/tex] = [tex]\frac{6}{7}[/tex]

What is the slope of the line? What is the y-intercept of the line? y = -3x + 4
Answer:
slope= -3/1
y-intercept= 4
Answer:
m = -3
y intercept = 4
Step-by-step explanation:
The given equation of the line is ,
[tex]\implies y = -3x+4[/tex]
We know that the Standard equation of Slope Intercept Form of the line is,
[tex]\implies y = mx + c[/tex]
Where ,
m is slope c is y interceptOn comparing to the Standard form of the line we get ,
[tex]\implies Slope = -3 [/tex]
[tex]\implies y - intercept= 4 [/tex]

Answer:
slope is undefined
Step-by-step explanation:
Calculate the slope m using the slope formula
m = [tex]\frac{y_{2}-y_{1} }{x_{2}-x_{1} }[/tex]
with (x₁, y₁ ) = (6, 2) and (x₂, y₂ ) = (6, - 3)
m = [tex]\frac{-3-2}{6-6}[/tex] = [tex]\frac{-5}{0}[/tex]
Division by zero is undefined , then slope is undefined

If a point (x, y) is reflected across y = -x, coordinates of the image point will be,
(x, y)→ (-y, -x)
Following this rule,
Vertices of the triangle will be,
(3, 1) → (-1, -3)
(3, -2) → (2, -3)
(6, -3) → (3, -6)
Therefore, image of the given triangle A will be,
(-1, -3), (2, -3) and (3, -6)
Sam rolls a fair dice and flips a fair coin.
What is the probability of obtaining an odd number and a head?
Answer:
1/4
Step-by-step explanation:
Given an event A and event B, the probability of both happening can be determined by multiplying the two individual probabilities.
We can start by finding the individual probabilities
The probability of rolling an odd number is 3/6 = 1/2, as there are 3 odd numbers (1,3,5) on a die and 6 possibilities total. Furthermore, there is a equal chance of rolling each number as it is a fair die
The probability of flipping a head is 1/2, as there are two equal possibilities (heads and tails), with one of them being heads
To find the probability of both happening, we can multiply them to get (1/2) * (1/2) = 1/4

The rate of electricity charge up to 20 units is Rs 3 per unit and Rs 7 per unit from 21 to 30 units. If a family paid the bill of Rs 166 with Rs 50 service charge, how many units of electricity was consumed in the month?
Answer:
28units consumed in month
Step-by-step explanation:
20unit=20×3=60rs
now service charge +60rs=110
similary total paid=166
now 166-110=56
and 56/7=8unit
since total unit=28unit

Answer:
180-(63+63)
=180-126
=54
180-(37+90)
180-127
53
180-(54+53)
=180-107
=73°
Answer:
Step-by-step explanation:
AC = AD So, Δ ACD is as isosceles triangle.
∠ADC ≅∠ACD = 63°
In ΔACD ,
63 + 63 + ∠DAC = 180 {Angle sum property of triangle}
126 + ∠DAC = 180
∠DAC = 180- 126
∠DAC = 54°
In ΔABC,
90+ 37 + ∠CAB = 180
127 + ∠CAB = 180
∠CAB = 180 - 127
∠CAB = 53
∠EAD + ∠DAC + ∠CAB = 180 {Straight line angles}
x + 54 + 53 = 180
x + 107 = 180
x = 180 -107
x = 73°
