Solve for b
Solve for b : -3b+2.5=4
Answer: -0.5
Step-by-step explanation:
-3b = 4-2.5
-3b = 1.5
(-3b)/-3 = 1.5/-3
b = -0.5
Answer:
should be - 0.5
Step-by-step explanation:
- 3b + 2.5 = 4
1.Turn the equation around
1. -3b = -2.5 + 4.
1. The reason why you turn the 2.5 into a negative is because you basically doing the oppisite if that makes sence.
2. Add -2.5 + 4
2. -2.5 + 4 = 1.5
2. I just added.
3. Plug 1.5 into the equation. Like so
3. -3b = 1.5
3. I just replaced -2.4 + 4 with the answer
4. Divied -3b = 1.5
4. -3b/-3b = 1.5/-3b = -0.5
4. What you do to one side you have to do to the other so -3b/-3b is 0 or it just is not there anymore next you take -3b and divide it by 1.5 and get - 0.5 BAM.
5. Plug -0.5 in for b.
5. -3(-0.5) + 2.5 = 4

2. A bag of dog food weighs 40 lb. By weight, 16% of the ingredients is turkey. Find the weight of turkey in the
dog food.
Answer:
Pretty sure it's 6.4 lbs
Step-by-step explanation:
We have to set up a proporion. So ?/40 and 16/100 because 16% of 100. Since we can't cross multiply 100 and ?, we have to cross multiply 16 × 40 = 640. We have 100 leftover, so 640÷100=6.4
Jason has 3/4 ton of stone to spread equally in 3 square yards . How many tons of stone will be spread in each square.
Answer:
3/12 ton
Step-by-step explanation:
Given data
Jason has 3/4 ton of stone to spread equally in 3 square yards
Let us divide the 3/4 ton equally by 3 to get the final answer
solution
=3/4/3
=3/4*1/3
= 3/12
Hence each square will take 3/12 ton
Savings Accounts
Alyssa starts with $30 and saves $5 each week. Bill has $16 and saves $7 each
week. At what week will Alyssa and Bill have the same amount of money?
Answer:
7 weeks
Step-by-step explanation:
Given data
Alyssa starts with $30 and saves $5 each week
let the number of weeks be x
y= 30+5x----------1
Bill has $16 and saves $7 each
week.
y= 16+7x----------------2
equate 1 and 2
30+5x= 16+7x
30-16= 7x-5x
14= 2x
x= 14/2
x= 7 weeks

Bruno leaves Ms. Crabbe's office to return to the gym. As he moves 450 meters in 2 minutes, what is his velocity? Be sure to write out your units of measurements for distance, time,
Answer: 225 meters per second
Step-by-step explanation:
Bruno was able to reach 450 meters in just 2 minutes.
His velocity therefore, can be determined by the speed formula which is:
= Distance / Time
= 450 / 2
= 225 meters per second
= 225 m/s
His velocity is 225 m/s.

compare using >,=,or <. -1.5_____-3/2. -4/5_____-5/4. -3/5_____-6/10. -2/3_____1/3
Answer:
-1.5 = -3/2
-4/5 > -5/4
-3/5 = -6/10
-2/3 < 1/3
Step-by-step explanation:
If you convert -3/2 into a decimal, it equals -1.5
-5/4 is an improper fraction which makes it greater than one, but since it is negative, it is further away from zero making it less than -4/5
-3/5 is the simplified form of -6/10. 3x2= 6 and 5x2=10
1/3 is positive making it greater than any negative

Dont have to answer immediately:>
Answer:
it is going to remain 3 1/2
Step-by-step explanation:
The absolute doesn't change anything since the term inside it is positive.
however if you were given | -3 1/2|, then in that case you would change the negative sign and make it positive.
state the domain of function, pa help po pls
Given:
The functions are:
(1) [tex]h(x)=\sqrt{1-x}[/tex]
(2) [tex]x+y=4[/tex]
(3) [tex]x^2+y^2=16[/tex]
To find:
The domain of given functions.
Solution:
Domain is the set of input and x -values.
Value under the square root must be positive because if the number under square root is negative, then it is a complex or imaginary number.
(1) [tex]h(x)=\sqrt{1-x}[/tex]
The function is defined if
[tex]1-x\geq 0[/tex]
[tex]1\geq x[/tex]
The function is defined for all real values of x which are less than or equal to 1.
Therefore, the domain of the function is (-∞,1].
(2) [tex]x+y=4[/tex]
It is a linear function and linear function is defined for all real values of x.
Therefore, the domain of the function is (-∞,∞).
(3) [tex]x^2+y^2=16[/tex]
It can be written as
[tex]y^2=16-x^2[/tex]
[tex]y=\pm \sqrt{16-x^2}[/tex]
It is defined if
[tex]16-x^2\geq 0[/tex]
[tex]16\geq x^2[/tex]
[tex]4\geq x\geq -4[/tex]
This function defined for all real values of x from -4 to 4.
Therefore, the domain of the function is [-4,4].

My teacher rlly tried to make it fun like girl nah it’s still hella boring
Please help with this right triangle problem
Given:
The figure of a right angle triangle.
To find:
The measure of side AB.
Solution:
In a right angle triangle,
[tex]\cos \theta=\dfrac{Adjacent}{Hypotenuse}[/tex]
In the given triangle,
[tex]\cos B=\dfrac{BC}{AB}[/tex]
[tex]\cos (20^\circ)=\dfrac{7}{AB}[/tex]
[tex]\cos (20^\circ)AB=7[/tex]
[tex]AB=\dfrac{7}{\cos (20^\circ)}[/tex]
On further simplification, we get
[tex]AB=\dfrac{7}{0.93969}[/tex]
[tex]AB=7.449265[/tex]
[tex]AB\approx 7.45[/tex]
Therefore, the measure of AB is 7.45 units.
What is the slope???
Answer:
detail below
Step-by-step explanation:
slope = difference of y/difference of x
m1 = (3-2) / (7-5) = 1/2
m2 = (-3 - -1) / (5 - 2) = -2/3
m3 = (3 - 6) / (-1 - -4) = -3/3 = -1
