Answer:
= -1.9f - 21
Step-by-step explanation:
Let's simplify
-2. 6f+ 0.7f- 12 - 9
= - 2.6f+ 0.7 f + - 12 + - 9
Combine like terms
= - 2.6 f+ 0.7 + - 12 + - 9
= (-2.6f + 0.7f ) + ( - 12+-9)
=1.9f+ -21

The steps are given.
To find:
The mistake in her steps.
Solution:
We have,
[tex]2x^4+2x^3-x^2-x[/tex]
The correct steps are shown below.
Step 1: Taking out x as common factor.
[tex]=x(2x^3+2x^2-x-1)[/tex]
Step 2: Now, taking out 2x² as common factor from first two terms (first group of terms) and -1 form last two terms (second group of terms) in the parentheses.
[tex]=x(2x^2(x+1)-1(x+1))[/tex]
Step 3: Taking out (x+1) as common factor.
[tex]=x(2x^2-1)(x+1)[/tex]
She incorrectly factored -1 from the second group of terms.
Therefore, the correct option is B.
For every dollar Bennett spent on bagels, Dominic spent 25 cents less. Bennett
paid $12.50 more than Dominic. How much did they spend in the bagel store together?
(A) $37.50 (B) $50.00 (C) $87.50 (D) $90.00
(E) $92.50
Answer:
The answer is C:$87.50
Step-by-step explanation:
Ben - 1$
David - 0.75$
For each Bagel, Ben paid 0.25$ extra.
Then the total bagel Ben bought = 12.5/0.25 = 50 and the money spent = 50$
Then david spent = 3/4*50 = 37.5$
Total = 50+37.5 =$87.50
Which of the following shapes are squares ? Please choose 2 correct answers !!!!!!!!!!!!! Will mark Brianliest !!!!!!!!!!!!!!!!!
Answer:
B,D
Step-by-step explanation:
Answer:
Hello again! Your answer would be B and D
Step-by-step explanation:
A square is a shape with 4 sides and all of them have to equal. Right away you can see that D is without needing to look at it. You might think that B is not because of its angle but if you turn your paper/computer to the side a bit you can there see that it is square. C and A are not because of their unequal sides. Yes, they do have four sides but they are non-equal.
Two of the angles in a triangle measure 51° and 25°. What must be the measure of the third angle?
Answer:
The measure of the third angle must be 104°
Step-by-step explanation:
Interior Angles of a Triangle
In any given triangle, the sum of its interior angles is 180°.
We are given the angles x=51° and y=25°. To find the third angle, z, we set up the equation:
x + y + z = 180
Solving for z:
z = 180 - x - y
Substituting:
z = 180 - 51 - 25
z = 104°
The measure of the third angle must be 104°
Which of the b-values satisfy the following inequality? 5 < b-3
a. b=8
b. b=9
c. b=10
Answer:
the values 9 and 10 satisfy the given inequality.
Step-by-step explanation:
Given inequality is:
[tex]5<b-3[/tex]
In order to find, which value of b satisfies the given inequality, we have to put the given values one by one in the inequality
Putting b = 8
[tex]5<8-3\\5 <5[/tex]
The inequality is not true for b=8.
Putting b=9
[tex]5<9-3\\5<6[/tex]
As the inequality is true for b=9, it satisfies the inequality.
Putting b=10
[tex]5<10-3\\5<7[/tex]
As the inequality is true for b=10, it satisfies the inequality.
Hence,
the values 9 and 10 satisfy the given inequality.
Answer:
The answer is b=9 and b=10

what’s the value of x trigonometry question
Answer:
x=9.2394
Step-by-step explanation:
It's tan we're going to use because we're looking for the opposite and we already have the angle
Therefore, x will be
Tan 57= x/6
1.5399= x/6
x= 6*1.5399
x= 9.2394
You can approximate it to the nearest whole number which will be 9

3. Write the equation of the line that passes through the point (-4,5) and has a slope of 1/4
Answer:
The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]
Step-by-step explanation:
Given information is:
(x,y) = (-4,5)
Slope = m = 1/4
The slope-intercept form of equation of a line is given by the formula:
[tex]y = mx+b[/tex]
Here
m is the slope of the line and b is the y-intercept.
Putting the value of slope in the equation
[tex]y = \frac{1}{4}x+b[/tex]
Now to find the y-intercept we will put the point in the equation
[tex]5 = \frac{1}{4}(-4) + b\\5 = -1+b\\b = 5+1\\b = 6[/tex]
The equation of line is:
[tex]y = \frac{1}{4}x+6[/tex]
Hence,
The equation of the line that passes through the point (-4,5) and has a slope of 1/4 is: [tex]y = \frac{1}{4}x+6[/tex]

Answer:20
Step-by-step explanation:
I done 8+8+4=20 because 8 was 40% so I added another 8 that made a 80% so then I cut the 8 and half because all I needed was
20% then which would be half of 40% and I ended up with 20 and that equally gave me a hundred percent

Step-by-step explanation:
A unit of gas costs 4.2 pence.
On average Ria uses 50.1 units of gas a week.
She pays for the gas she uses in 13 weeks.
Work out an estimate for the amount Ria pays.
Answer:
2735.46 pence or £27.35
Step-by-step explanation:
if she uses 50.1 units a week, in 13 weeks she will use 651.3 units. the cost for 651.3 units is 2735.46 pence. We can round this to £27.35.
The required cost of the gas as of the 13-week usage of gas is 2735.46 pence.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
A unit of gas costs 4.2 pence. On average Ria uses 50.1 units of gas a week. She pays for the gas she uses in 13 weeks.
The cost of gas for 13 weeks, is given as,
= 4.2 × 50.1 × 13
= 2735.46 pence
Thus, the required cost of the gas as of the 13-week usage of gas is 2735.46 pence.
