Answer:
x= -14
Step-by-step explanation:
-x+3x-x=-8-6
x= -14
-x+8+3x=x-6
the first thing we need to do is move the x's to the left and the numbers to the right
when moving a number from one side to another it's sign is changed
-x+3x-x=-6-8
x=-14

Round to the nearest percent. Use the drop-down menus to show and explain your answer.
The greatest growth was between years
and
The growth between those years was about
Answer:
Greatest growth was between : year 3 and year 4
Percentage growth was about 32%
Step-by-step explanation:
Given the data:
Year : ______1 ____ 2 _____ 3 _______ 4
Students: __ 14 ___ 19 _____ 25 ______ 33
Number of students :
Year 1 & year 2 = 19 - 14 = 5
Year 2 & year 3 = 25 - 19 = 6
Year 3 & year 4 = 33 - 25 = 8
Hence,The two years at which the greatest growth was observed is between year 3 and year 4.
Percentage growth :
((33 - 25) / 25) * 100%
(8 / 25) * 100%
0.32 * 100%
= 32%

A financial institution offers a "double-your-money" savings account in which you will have $2 in 11 years for every dollar you invest today. What annual interest rate does this account offer? Please specify your answer in decimal terms and round your answer to the nearest thousandth (e.G., enter 12.3 percent as 0.123).
Answer:
[tex]r=0.07[/tex]
Step-by-step explanation:
From the question we are told that
An offer of 2$ in 11 years on every dollar
Generally we make use of this formula
[tex]F=P(1+r/100)^t[/tex]
where
[tex]f=Future value[/tex]
[tex]P= present value[/tex]
[tex]r=Rate[/tex]
[tex]t=time[/tex]
Mathematically solving for the rate
[tex]2=1(1+r/100)^1^1[/tex]
[tex](2)^1^/^1^1=(1+r/100)[/tex]
[tex](1+r/100=1.0650[/tex]
[tex]r=(1.0650-1) *100[/tex]
[tex]r=0.07[/tex]
Generally this shows that the account give an annual rate of 0.07

James and Sylvie need to paint the line around the outside of a soccer field. To know how much paint to buy, they must find the perimeter of the field. James claims, “I can calculate the perimeter by using the formula P = 2(l + w) .” Sylvie replied, “That’s not right. The correct formula is
P = 2l + 2w .” Who is correct? Provide evidence to support your answer.
Answer:
Both of them are correct.
The perimeter is found by adding up all four sides. If you notice, one of them is width and one of them is length. A rectangle has four sides, two width and two length.
l= length and w=width so P=2l+2w.
But, we can combine them by factorizing 2l+2w.
Lets see what we can pull out. We can only pull out 2.
2(l+w)=2l+2w.
2(l+w)=P
Both of them are correct.

Find area of shaded region if
Theta = 60°
Radius (r = 5cm)
Answer:
≈ 13.1 cm²
Step-by-step explanation:
The area (A) of the sector is calculated as
A = area of circle × fraction of circle
= πr² × [tex]\frac{60}{360}[/tex]
= π × 5² × [tex]\frac{1}{6}[/tex]
= 25π ÷ 6
≈ 13.1 cm² ( to 1 dec. place )
Answer:
area = 13.1 cm²
Step-by-step explanation:
area of sector formulae:
[tex] \frac{theta}{360} \times \pi {r}^{2} [/tex]
theta = 60°
radius = 5 cm
π = 22/7
substitute the values into the formulae
[tex] \frac{60}{360} \times \frac{22}{7} \times {5}^{2} [/tex]
[tex] \frac{1}{6} \times \frac{22}{7} \times 25[/tex]
[tex] \frac{1}{6} \times \frac{25 \times 22}{7} [/tex]
[tex] \frac{1}{6} \times \frac{550}{7} [/tex]

Suppose that Cecil, the tightrope walker, can only travel lengths of 5 feet, 6 feet, and 8 feet.
• He can travel forward (positive 5, 6, 8)
• backward negative (-5, -6-8)
can go past the ladder and come back.
.
Show TWO number expressions that will represent a way for Cecil to cross a tightrope of
12 feet. ONE way MUST use a negative.

Answer:
The two expressions are;
1) -8 ft. + 3 × 6 ft. = 12 feet
2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet
Step-by-step explanation:
The given parameters are;
The lengths in feet Cecil can travel = 5 feet, 6 feet, and 8 feet
The distances Cecil can travel forward = (positive 5, 6, 8)
Backwards Cecil can travel distances of (-5, -6, -8)
Cecil can go forward past the ladder and return back
Therefore, the number expressions by which Cecil can cross a tightrope 12 feet long are;
1) -8 ft. + 3 × 6 ft. = 12 feet
Which is to go back 8 feet and then to go forward 6 feet three times
2) -6 ft. + 2 × 5 ft. + 8 ft. = 12 feet
Which is to go back 6 feet then to go forward in 5 feet two times and then in forward again in 8 feet.
4. Find the value of the real number y such that
(3+2i)(1 + iy)
is :
(a) real
(b) imaginary
Step-by-step explanation:
(3 + 2i)(1 + iy)
= 3 + (3y + 2)i - 2y (because i² = -1)
For this to be real, (3y + 2) = 0. => y = -2/3
For this to be imaginary, y can be any real or complex number (except -2/3)
write the fraction 32/40 in simplest form
Answer:
4/5
Step-by-step explanation:
32/40
Both can be divisible by 4
32 ÷ 4 = 8
40 ÷ 4 = 10
8/10
8 and 10 can be simplified again by 2
8 ÷ 2 = 4
10 ÷ 2 = 5
4/5
This cannot be simplified anymore, to check just divide.
32/40 = 0.8
4/5 = 0.8
The simplified form of 32/40 is 4/5.
How to simplify the fraction 32/40To simplify the fraction 32/40, we can find the greatest common divisor (GCD) of the numerator (32) and denominator (40) and divide both by that value.
The GCD of 32 and 40 is 8. By dividing both the numerator and denominator by 8, we can simplify the fraction:
32 ÷ 8 = 4
40 ÷ 8 = 5
Therefore, the simplified form of 32/40 is 4/5.

Answer:
Step-by-step explanation:
unit rate is another way of saying "slope of the line"
3/2 is the slope of the line..just from inspection of the graph
1.5 is another way to say 3/2 and that's how me might normally say the cost of one watermelon... it's a $1.50 so the unit rate is 1.5 units.. and here the units are dollars
