rearranging formula Solve 4(x + 3) = 6
Answer:
x = - [tex]\frac{3}{2}[/tex]
Step-by-step explanation:
Given
4(x + 3) = 6 ← distribute left side
4x + 12 = 6 ( subtract 12 from both sides )
4x = - 6 ( divide both sides by 4 )
x = [tex]\frac{-6}{4}[/tex] = - [tex]\frac{3}{2}[/tex]

1) In triangle ABC, we know that AB = 5, BC = 9, and CA = 7. D is a point on BC such that AD bisects ∠BAC. What is DC?
2)] O is the circumcenter of 4ABC. If OB = OC = BC, what is ∠BAC
9514 1404 393
Answer:
1) 5.25
2) 95.74°
Step-by-step explanation:
1) The angle bisector divides the triangle into proportional segments.
DC/BD = CA/BA
We know that BD+DC = 9, so we can fill in the above equation with known values to get ...
DC/(9-DC) = 7/5
5·DC = 7(9 -DC) . . . . cross multiply
12·DC = 63 . . . . . add 7·DC
DC = 63/12 = 5.25
__
2) Angle BAC can be found using the Law of Cosines.
a² = b² +c² -2bc·cos(A)
cos(A) = (b² +c² -a²)/(2bc) = (7² +5² -9²)/(2·7·5) = -7/(70) = -1/10
A = arccos(-1/10) ≈ 95.739°
The measure of ∠BAC is about 95.74°.

Step-by-step explanation:
Answer:
h<−7/4
Step-by-step explanation:
−4h−3>4
Step 1: Add 3 to both sides.
−4h−3+3>4+3

Step 2: Divide both sides by -4.
−4h / −4 > 7 / −4
h< −7 /4
Jacob checked two bags of potato chips for broken chips. The first bag
had 6 broken chips, which was 10% of the chips in bag 1. The second bag
had 12 broken chips, which was 25% of the chips in bag 2. How many
total chips were in both bags?
Answer:
3
Step-by-step explanation:
Total 108 chips were in the both bags.
What is a percentage?A ratio or value that may be stated as a fraction of 100 is called a percentage. And it is represented by the symbol '%'.
10% of chips in the first bag is 6.
To find the total chips in the first bag:
6 = 10 x total number of chips in the first bag / 100
total number of chips in the first bag = 600/10
total number of chips in the first bag = 60
25% of chips in the second bag is 12.
To find the total chips in the second bag:
12 = 25x total number of chips in the second bag / 100
total number of chips in the second bag = 1200/25
total number of chips in the second bag = 48
Now, total chips in the both bags = 60 + 48 = 108
Therefore, total 108 chips were in the both bags.

A fish tank has 42 gallons of water and is being drained at a rate of 2 gallons per minute. Another tank is empty and is being filled at a rate of 4 gallons per minute. After how many minutes will both tanks have the same amount of water?
Answer:
6 mins and 30 secs
Step-by-step explanation:
After 7 minutes, both tanks have the same amount of water.
What is a mathematical function, equation and expression?function : In mathematics, a function from a set X to a set Y assigns to each element of X exactly one element of Y. The set X is called the domain of the function and the set Y is called the codomain of the function.expression : A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.equation : A mathematical equation is used to equate two expressions.
Given is that a fish tank has 42 gallons of water and is being drained at a rate of 2 gallons per minute. Another tank is empty and is being filled at a rate of 4 gallons per minute.
We can write the drain function as -
D(x) = 42 - 2x
The function that gives the amount of water in second tank will be -
F(x) = 4x
Equating both, we get -
D(x) = F(x)
42 - 2x = 4x
42 = 6x
x = 42/6
x = 7
Therefore, after 7 minutes, both tanks have the same amount of water.

A survey of all planet Umpt found that 36 beings preferred dubble juice to all the other juices. If 40 being were surveyed all together, what percent of them preferred dubble juice.
Answer:
90%
Step-by-step explanation:

-5(3x-7)+11=1 What would this be?
Answer:
x = 3
Step-by-step explanation:
-5(3x -7) + 11 = 1
Distribute 5:
-15x + 35 + 11 = 1
Combine like terms:
-15x + 46 = 1
Subtract by 46 =
-15x = 1 - 46
-15x = -45
Divide by -15:
x = -45 / -15
x = 3
Answer:
x=3
Step-by-step explanation:
Use the distributive property to multiply −5 by 3x−7.
−5(3x−7)+11=1
Add 35 and 11 to get 46.
−15x+35+11=1
Subtract 46 from both sides.
−15x+46=1
Subtract 46 from 1 to get −45.
−15x=1−46
Divide both sides by −15 and you get x=3.

Every week, Hector works 20 hours and earns $210.00. He earns a constant amount of money per hour.
Part A
Write an equation that can be used to determine the number of hours, h, Hector works given the number of weeks, W.
Enter your equation in the space provided
Part B
Write an equation that can be used to determine Hector's earnings, in dollars, m, for h hours of work.
Enter your equation in the space provided.
Answer:
A). h = 20 w
B). m = 10.5h
Step-by-step explanation:
Part (A).
Let the total number of hours Hector worked = h
And total number of weeks worked by Hector = w
Therefore, number of hours Hector worked in a week = [tex]\frac{h}{w}[/tex]
Since, total number of hours worked in a week = 20
Equation will be,
20 = [tex]\frac{h}{w}[/tex]
h = 20w
Part (B).
Per hour earning of Hector = [tex]\frac{\text{Total earning}}{\text{Number of hours worked}}=\frac{210}{20}[/tex]
[tex]\frac{m}{h}=10.5[/tex]
m = 10.5h

Sarah is a computer engineer and manager and works for a software company. She receives a fixed annual increase in the number of projects she handles each year. She worked on 129 projects in the fourth year of her employment and 207 projects in her tenth year
Answer: See explanation
Step-by-step explanation:
You didn't say what you'll like to calculate but let me help out.
Fourth year = 129 project.
Tenth year = 207 projects
We can form this into an arithmetic progression
Tn = a + (n-1)d
4th year = a + 3d = 129 ........ i
10th year = a + 9d = 207 ....... ii
Subtract equation i from equation ii
6d = 78
d = 78/6 = 13
This means that 13 new projects are added every year
For the first year, the number of projects done was:.
a + 3d = 129
a + 3(13) = 129
a + 39 = 129
a = 129 - 39 = 90
She worked on 90 projects in the first year.
