1. 3b + 9 -5b + 3 = -14 + 6b - 8
2. 2x + 5 - 4x + 8 = 5(5 + 6x) - 12x
I can help you!
Answer:
1) b = 17/4
2) x = -3/5
Step-by-step explanation (question one):
Step 1: Simplify both sides of the equation.
3b +9 + −5b + 3 = −14 +6b +−8
(3b +−5b) +(9 +3)=(6b) +(−14 + −8) (Combine Like Terms)
−2b +12 = 6b −22
Step 2: Subtract 6b from both sides.
−2b +12 −6b = 6b −22 −6b
−8b +12 = −22
Step 3: Subtract 12 from both sides.
−8b +12 −12 = −22 −12
−8b = −34
Step 4: Divide both sides by -8.
(-8b/-8) = (-34/-8)
Step 5: Get your Answer
b = 17/4
Step-by-step explanation (question two):
Step 1: Simplify both sides of the equation.
2x +5 + −4x +8 = (5)(5) +(5)(6x) + −12x (Distribute)
2x +5 + −4x +8 = 25 +30x + −12x
(2x+−4x) + (5+8) = (30x +−12x) +(25) (Combine Like Terms)
−2x +13 = 18x +25
Step 2: Subtract 18x from both sides.
−2x +13 −18x= 18x +25 −18x
−20x +13 = 25
Step 3: Subtract 13 from both sides.
−20x +13 −13 = 25 −13
−20x=12
Step 4: Divide both sides by -20.
(-20x/-20) = (12/-20)
Step 5: Get your Answer
x = -3/5

Answer:
b = 17/4 x = -3/5Step-by-step explanation:
1) 3b + 9 - 5b + 3 = -14 + 6b - 8, for b?
→ 3b + 9 - 5b + 3 = -14 + 6b - 8
→ -2b + 12 = 6b - 22
→ -2b - 6b = -22 - 12
→ -8b = -34
→ b = -34/-8
→ [ b = 17/4 ]
Hence, the value of b is 17/4.
2) 2x + 5 - 4x + 8 = 5(5 + 6x) - 12x, for x?
→ 2x + 5 - 4x + 8 = 5(5 + 6x) - 12x
→ -2x + 13 = 25 + 30x - 12x
→ -2x - 18x = 25 - 13
→ -20x = 12
→ x = 12/-20
→ [ x = -3/5 ]
Hence, the value of x is -3/5.
On my last birthday, a friend said
to me:
"In 15 years' time, your age will be
the square of your age 15 years
ago!"
Can you work out how old I am?
let thee present age be x.
(x-15)^2=x+15
=>x^2–31*x+210=0
=>(x-21)(x-10)=0
x=10 or x=21
present age can not be 10 as it would result at absurd negative age( -5) 15 years ago.
so present age is 21.
If c = 12, which statement is true?
A. c is 5 times as many as 4
B. 27 is c times as many as 3
C. 6 times as many as c is 72
D. 8 more than c is 15
Answer:
C. 6 times as many as c is 72
Step-by-step explanation:
You want to know if c = 12, which statement is true.
We can substitute 12 for c in each expression and write it as a math equation. That makes it easier to see if it is true.
A. c is 5 times as many as 412 = 5×4
12 = 20 . . . . . false
B. 27 is c times as many as 327 = 12×3
27 = 36 . . . . . false
C. 6 times as many as c is 726×12 = 72 . . . . . TRUE
D. 8 more than c is 158 + 12 = 15
20 = 15 . . . . . false

In the question ,
it is given that ,
there are 2 circles , 4 triangles , 2 squares .
(a) probability of not picking a square = ( circles + triangles )/total

The sum of an integer and 4 times the next consecutive even integer is 58. Find the
value of the greater integer.
By solving a linear equation, we will see that the value of the greater integer is 12.
How to find the greater integer?Let's define x as the smaller integer, then the greater integer is:
x + 2
(is +2 because is the next consecutive even integer)
We know the sum of an integer and 4 times the next consecutive even integer is 58.
So we can write the linear equation:
x + 4*(x + 2) = 58
x + 4x + 8 = 58
5x = 58 - 8
5x = 50
x = 50/5
x = 10
Then the greater integer is x + 2 = 10 + 2 = 12

The figures below show the top view and right-side view of a rectangular prism that is completely packed with unit cubes.
How many unit cubes would it take to completely fill the prism with no gaps between unit cubes?
The number of unit cubes it would take to completely fill the prism with no gaps between unit cubes is 72
Calculating the number of cubes required to fill a prismFrom the question, we are to determine how many unit cubes it would take to completely fill the prism with no gaps between unit cubes.
To do this, we will calculate the volume of rectangular prism
Assuming each cube is 1 cubic unit
Then,
From the top view,
The length of the rectangular prism = 9 units
The width of the rectangular prism = 2 units
From the Right-side view,
The height of the rectangular prism = 4 units
Thus,
The volume of the rectangular prism = 9 × 2 × 4
Volume of the rectangular prism = 72 cubic units
Now,
Number of cubes required to fill the rectangular prism = Volume of the prism / Volume of the cubes
Number of cubes required to fill the rectangular prims = 72 / 1
Number of cubes required to fill the rectangular prims = 72
Hence, the number of unit cubes it would take is 72

A store sells 12 cans of soup for $7. 50 how much would it cost to purchase 6 cans of soup?.
Answer: $3.75
Step-by-step explanation:
Answer:
The cost of 6 cans of soup is 3.75
Step-by-step explanation:
12 = 7.50
1 can = x
12x = 7.50
We need to find the cost of 1 can. So we divide 7.50 by 12.
x = 0.625
Then multiply by 6.
0.625 x 6 = 3.75
As a result the cost of 6 cans of sup is $3.75

As part of his semester project, a byu-idaho introductory statistics student calculates a 95% confidence interval for the true percentage of byu-idaho students who are from latin america. What does the phrase 95% confidence mean?.
"95% confidence interval" means that there is a 95% chance that the true fraction falls within the computed confidence interval.
Confidence Intervals: Confidence intervals are the range of estimates for unknown parameters.
Confidence intervals are more than just a range of estimated values. It also tells you how stable the estimates are. A stable estimate is an estimate that has approximately the same value if the study is repeated. An unstable estimate is one that would vary from one sample to another.
The confidence interval determines the range that one can be certain that contains the true mean of the population.
This means that, The 95% confidence means, there is a 95% chance that the true proportion will be in the calculated confidence interval or 95 percent confidence interval, you have a 5 percent chance of being wrong.
Hence, the true statement that represents "95% confidence interval" is chance of true fraction of sucess.
