-5(3x-7)+11=1 What would this be?
Answers
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.

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?
Answers
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.

Find the value of x.
28°
Answers
The value of x is 56 degrees.
What is a Right Angle Triangle ?A right angle triangle is any angle in which the value of the angle is 90°
The value of the other angle in the right angle will be 90 - 28 = 62°
Since the two triangles in the figure are isosceles triangles, the two angle at the base of an isosceles triangle will be the same.
Sum of the angle of a triangle = 180°
Then, 62 + 62 + x = 180
124 + x = 180
make x the subject of formula
x = 180 - 124
x = 56
Therefore, the value of x is 56 degrees.

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
Answers
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°.

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
Answers
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.

Leslie can buy her dog's food at Petco for $25 and receive 9 packs with four cans in each. Leslie can buy the same food at Petsmart for the same price with 7 packs of six cans in each. Which store should Leslie buy her dog food from?
Answers
Answer:
Leslie should buy her dog food from Petsmart because the price per can is cheaper
Step-by-step explanation:
Step one;
given data
At Petco, we are told that she receives 9 packs with four cans each for $25
Hence Petco gives a total of 9*4= 36cans
the cost of each can will be 25/36
=$0.69 per can
Step two:
At Petsmart, we are told that she receives 7 packs with six cans each for $25
Hence Petsmart gives a total of 7*6= 42cans
the cost of each can will be 25/42
=$0.59 per can
Leslie should buy her dog food from Petsmart because the price per can is cheaper
