Answer:
x = 4, 10a
Step-by-step explanation:
3(x-2) + 2(2x+5) = 32
3x - 6 + 4x + 10 = 32
3x + 4x + 10 - 6 = 32
7x + 4 = 32
7x = 32 - 4
7x = 28
Divide both side by 7
x = 4
a + 2a + 7a
They are common because the have the same variables.
'a' is with a coefficient of 1
You add the coefficient and attach the variable to it
Therefore,
a + 2a + 7a = 10a

Step-by-step explanation:
n Over 54 EndFraction = StartFraction 4 Over 9 EndFraction
n/54 = 4/9
Cross product
n * 9 = 54 * 4
9n = 216
n = 216/9
n = 24
A. 24
Check:
n/54 = 4/9
24 / 54
Divide through by 6
= 4/9
Would the answer be 550.25?
Answer:
$52.50
Step-by-step explanation:
1. You take 550 and divide by 5.
2. Then you would takw that number (105) and multiply by 2 (210)
3. Then you take 210 and divide by 4 which equals 52.5
4. The answer is 52.5 because she takes 1/4 of the 2/5 for vacation a month.

Answer:
Angle 2 = Angle 4 = 76
Step-by-step explanation:
Here, we want to get the measures of angle 2 and angle 4
From what we have in the diagram, angle 2 and angle 5 are supplementary (meaning they add up to 180)
The reason for this is because both angles are same side interior angles
Thus,
angle 2 + angle 5 = 180
angle 2 = 180 - angle 5
angle 2 = 180 -104
angle 2 = 76
Furthermore, we can see that angle 2 equals angle 4 as they are vertically opposite angles
Thus, angle 2 = angle 4 = 76

First, consider the number of moves as a
sequence: 1, 3, 7, 15, 31, 63,
.
To find a pattern, look at the differences between
consecutive terms. These differences also form a
sequence.
3-1 = 2,7 – 3 = 4, ...
Complete the sequence:
2, 4, ___, ___, ____
Answer:
The sequence is 2, 4, 8, 16, 32
The next answer is 2
Step-by-step explanation:
The missing terms of the required sequence are 8, 16 and 32 respectively.
What is a geometric sequence?In a geometric sequence, the ratio of two consecutive terms are always equal.
The general expression for the nth term is given as aₙ = a₁ × rⁿ⁻¹ .
The sum of n terms for this sequence is given as Sₙ = (rⁿ - 1)/(r - 1)
The given sequence is 1, 3, 7, 15, 31, 63...
Then, the sequence formed by subtracting the consecutive terms are given as,
3 - 1, 7 - 3, 15 - 7, 31 - 15, 63 - 31 .....
Which can be rewritten as,
2, 4, 8, 16, 32......
It is a geometric sequence as ratio of the consecutive terms are equal,
4/2 = 8/4 = 16/8
Hence, the required sequence is a geometric sequence found as 2, 4, 8, 16, 32......

Amanda slept for 1/3 of the day. She played with her friends for 1/5 of the day. She spent the rest of the day working on a school project. What fraction of the day did she spend working on her project?
Answer:
She spent 7/15 of the day working on her project.
Step-by-step explanation:
Well we cant get a clear answer with the fractions 1/3 and 1/5, so we are going to have to turn them into equivalent fractions.
3 and 5 both have 15 LCD so:
1/3 x 5/5 = 5/15
1/5 x 3/3 = 3/15
5/15 + 3/15 = 8/15
15/15 - 8/15 = 7/15
She spent 7/15 of the day working on her project.

Write the equation of the line that is perpendicular to y = -2/3 x +2 and goes through the point (-1, 4). Make sure your final answer is in slope-intercept form
Given:
The equation of a line is
[tex]y=-\dfrac{2}{3}x+2[/tex] ...(i)
The perpendicular line passes through the point (-1,4).
To find:
The equation of the perpendicular line.
Solution:
The slope intercept form of a line is:
[tex]y=mx+b[/tex] ...(ii)
Where, m is the slope and b is the y-intercept.
On comparing (i) and (ii), we get
[tex]m=-\dfrac{2}{3}[/tex]
Product of slopes of two perpendicular lines is -1.
Let the slope of perpendicular line is [tex]m_1[/tex].
[tex]m\times m_1=-1[/tex]
[tex]-\dfrac{2}{3}\times m_1=-1[/tex]
[tex]m_1=\dfrac{3}{2}[/tex]
The slope of the perpendicular line is [tex]m_1=\dfrac{3}{2}[/tex] and it passes through the point (-1,4). So, the equation of the line is:
[tex]y-y_1=m_1(x-x_1)[/tex]
[tex]y-4=\dfrac{3}{2}(x-(-1))[/tex]
[tex]y-4=\dfrac{3}{2}(x+1)[/tex]
[tex]y-4=\dfrac{3}{2}x+\dfrac{3}{2}[/tex]
Add 4 on both sides.
[tex]y-4+4=\dfrac{3}{2}x+\dfrac{3}{2}+4[/tex]
[tex]y=\dfrac{3}{2}x+\dfrac{3+8}{2}[/tex]
[tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex]
Therefore, the equation of required line is [tex]y=\dfrac{3}{2}x+\dfrac{11}{2}[/tex].

Please help me on this ASAP am I right ?
Answer:
No, you would graph the y-intercept, you do not graph the m-value (slope). The slope value is the rate that the y-value increases per unit of x. This is how you graph your line from the y-intercept
Answer:
No you are incorrect. The correct answer is (y - intercept) b = -4
Step-by-step explanation:
You need to plot the y - intercept first so that you can create the line using the slope starting from the y - intercept. You can't plot the line unless you first plot a point on the line which would be the y - intercept or -4 THEN from there you use the slope to create the line.

2x+ 40 = 180
Answer:
X+30+x+10=180
combine like terms
2x+40=180
subtract 40 from both sides
2x=140

YOU JUST OPEN YOUR FIRST BUSINESS YOU HAVE RENT $1,000 YOUR FIRST ORDER OF PRODUCT WAS $10,000 YOU PHONE BILL IS $120 FOR 4 LINES, ELECTIRC BILL FOR THE FIRST MONTH IS $150, AND YOUR HEAT BILL IS $200 HOWEVER, SPRING IS NEAR SO YOU CAN CUT YOUR HEAT OFF. NOW ITS TIME TO PAY YOUR SELF AND EMPLOYEES. YOUR SALARY IS $5,000 EVERY OTHER WEEK AND YOU HAVE WAGES OF $20,000. .HOW MUCH IS YOUR TOTAL COST? *
Answer: $26,470
Step-by-step explanation:
Total costs are all the expenses that have to be paid by your business to keep it producing.
In this case that figure is:
Total cost = Rent + Phone bill + Electric bill + Heat bill + own salary + Wages
= 1,000 + 120 + 150 + 200 + 5,000 + 20,000
= $26,470

9514 1404 393
Answer:
(a, b, c) = (-0.425595, 11.7321, 2.16667)
f(x) = -0.425595x² +11.7321x +2.16667
f(1) ≈ 13.5
Step-by-step explanation:
A suitable tool makes short work of this. Most spreadsheets and graphing calculators will do quadratic regression. All you have to do is enter the data and make use of the appropriate built-in functions.
Desmos will do least-squares fitting of almost any function you want to use as a model. It tells you ...
a = -0.425595
b = 11.7321
c = 2.16667
so
f(x) = -0.425595x² +11.7321x +2.16667
and f(1) ≈ 13.5

Note that a quadratic function doesn't model the data very well if you're trying to extrapolate to times outside the original domain.

955.5 cm squared
1,029 cm squared
Answer:
4. A = 1029 cm²Steps:
A = (35×21)+(21+2×3.5)×21/2
A = 735 + (21+7)×21/2
A = 735 + 28×21/2
A = 735 + 588/2
A = 735 + 294
A = 1029 cm²
