Explanation:
The angle -450 is not between 0 and 360. Add on 360 so that we do one full revolution to get -450+360 = -90.
The angle -90 isn't between 0 and 360 either. We repeat the last step by adding on 360 to get -90+360 = 270.
The result 270 is between 0 and 360, so we stop here.
The angle -450 and 270 both point in the same direction. Both point directly south. This is why they are considered coterminal angles.

7x + 5y - X + 2y + 3x
Answer:
9x+7y
Step-by-step explanation:
please see the image that I have attached
Hey there!
The simplified expression is 3x + 7y
To simplify this, we must add like terms. We can use the Commutative Property of addition to move the like terms together:
7x - x + 3x + 5y + 2y
Now, we can use the Associative Property to group the numbers:
(7x - x + 3x) + (5y +2y)
Now, we add the terms in the parentheses:
3x + 7y
Hope it helps and have a great day!!!
Pemba is 5 yrs older than her sister.If the sum of their ages is 35 yrs, find their ages
Answer:
Pemba is 20 and her sister 15
Step-by-step explanation:
Let the sisters age be x. As pemba is five years older, her age is x+5.
Now, the sum of their ages is 135. So, by combining the two ages we get:
=>X+(x+5)=35
x+x+5=30
2x=30
x = 15
Then, substitituing this value of x into our equations for the ages of the sisters we get
sisters age 15 years old
Pemba age (15)+5=20 years old
The length of a rectangle is 4 cm longer than the width, The perimeter is 80 cm. Find the length and the width. Substition Method, Elimanation Method.
Answer: Length = l
Width = w
2l + 2w = 80cm
l+w = 40cm
l = w+4
w+4 + w = 40cm
2w + 4 = 40cm
2w = 36cm
w = 18cm
l = 22cm
jd3sp4o0
Step-by-step explanation:
Answer:
L = 22, W= 18
Step-by-step explanation:
You can use an equation to solve this. Since the length is 4 more than the width, you can use L = W + 4. (L = Length, W = Width). I personally like to draw a diagram to figure out the total sides. We can add up all the sides, using our equations and adding common factors. We know the perimeter is 80 cm, so we can equal it to this. Solve for W. And finally subsitute for L.
I really need help on this. Thank you
What is the slope of the line that passes through the points
(9,-1) and (4, -11)? Write your answer in simplest form.
Answer: m = 2
Step-by-step explanation:

Solve the equation:
4y2 + 7 = 19
(write your answer in exact form)
Answer:
y2=3
Step-by-step explanation:
4y2+7=19
Subtract 7 from both sides.
4y 2 =19−7
Subtract 7 from 19 to get 12.
4y2=12
Divide both sides by 4.
y2= 12/4
Divide 12 by 4 to get 3.
y2=3
Answer:
4y2 + 7 = 19
Step-by-step explanation:
4y2 =19-7
4y2=12
4yx2=12
8y=12

NEED ASAP!!! WILL MARK BRAINLLIEST!!!!!! A student solved the equation 7x - 5 - 5x = 15 and found x = 5. What is the student's error?
Answer:
the student messed up at the point of adding 5 to I5, they subtracted instead and got 2x=I0 which would mean x=5. when instead they should've added 5 and got 2x=20 and got x=I0
Brad has 10 lb of oranges to make 12 bowls of fruit salad. His recipe requires 12 oz of oranges for each bowl. Does Brad have enough oranges? Please answer....
Answer: Yes, Brad has enough oranges.
Step-by-step explanation:
Given :
The orange required for one bowl = 12 oz
Thus orange required for 12 bowls = [tex]\frac{12}{1}\times 12=144oz[/tex]
Oranges available with Brad for 12 bowls = 10 lb = [tex]10\times 16=160oz[/tex]
(1lb=16oz)
As organges required is less than oranges available with Brad, thus Brad has enough oranges.
Solve the system of equations using eliminations
4x + 3y = -5
-2x + 2y = 6
I really need help with this questions someone please help
Answer:
x= -2 and y= -1
Step-by-step explanation:
1) 4x+3y= -5
2(-2x+2y=6)
(Multipy by 2 )
Becomes
2) 4x+3y= -5
-4x+4y=12
3) -5+12 =7
7y/7=7/7=
y=1
4x+3y=-5
4x+3(1)= -5(plug in Y for 1)
4x+3= -5
4x+3+-3= -5+ -3 (add neigitve 3 on both sides)
4x= -8
4x/4=-8/4( divide 4 on both sides)

How much interest do you earn when you deposit $100 at 25% for 2 years?
Answer:
For simple interest: $50, for compound interest: $56.25
Step-by-step explanation:
For simple interest: 25% *100 = $25
$25*2 = $50
For compound interest:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25
Answer:
Year 1) 100+100(.25) = 125
Year 2) 125+125(.25) = 125+31.25 = $156.25
156.25 - 100 = $56.25

-3 + 42 > 3
x > 15
x < 15
x > 13
x < 13
Answer:
Where's the x?
I am assuming that the problem must be
-3 + 42 > 3x
if that is true, then
x < 13.
As this statement is, -3 + 42 > 3 is a true statement because -3 + 42 = 39, and
39 > 3 [39 is always greater than 3]
Step-by-step explanation:
Let me know if you need a step by step.
Answer:
D) x < -15
Step-by-step explanation:
-3x - 42 >3
Add 42 to each side
-3x - 42+42 >3+42
-3x > 45
Divide each side by -3. Remember to flip the inequality since we are dividing by a negative
-3x/-3 < 45/-3
x < -15
not really sure how you want this solved but the equation itself is true

Find the area of the isosceles triangle.
13 cm
10 cm
Answer:
Area of the triangle = 60 cm²
Step-by-step explanation:
Two equal sides of the given isosceles triangle measure 13 cm.
Third side of the triangle = 10 cm
Since, formula to get the area of a triangle with given three sides is given by,
Area = [tex]\sqrt{s(s-a)(s-b)(s-c)}[/tex]
Where a, b and c represent the sides of the triangle
And s = [tex]\frac{a+b+c}{2}[/tex]
For the given isosceles triangle,
s = [tex]\frac{13+10+13}{2}[/tex]
s = 18
(s - a) = (18 - 13) = 5 cm
(s - b) = (18 - 10) = 8 cm
(s - c) = (18 - 13) = 5 cm
Substituting these values in the formula,
Area of the triangle = [tex]\sqrt{18\times 5\times 8\times 5}[/tex]
= [tex]\sqrt{3600}[/tex]
= 60 cm²
Therefore, area of the given isosceles triangle is 60 square cm.

A band expects to put 16 songs on their next CD. The band writes and records 75% more songs than they expect to put on the CD. During the editing process, 75% of the songs are removed. How many songs will there be on the final CD?
do this step by step.
16 X 1.75
- since there is 75% more.
= 28 songs --> in total.
28 X 0.25
-- since 75% are removed.
= 7
final answer: 7 songs.
solve using elimination 10x - 9y = -8 and 2x - 8y = -14
Answer:
x = 1, y = 2
Step-by-step explanation:
Multiply 2x - 8y = -14 by 5 to get 10x - 40y = -70
Subtract (10x - 40y = -70) - (10x - 9y = -8)
Solve -31y = -62 for y
y = 2
Plug in y value to get x value
x = 1
solve this question: 2x+5is less than or equal to 3x+1,xeN.Want full working please
Answer: 4 ≥ x
Step-by-step explanation:
We want to solve the inequality
2*x + 5 ≥ 3*x + 1
We can solve it in the same way as a normal equation, we need to isolate x in one side of the equation.
I will isolate x in the right side.
2*x + 5 ≥ 3*x + 1
First, we subtract 2*x in both sides:
(2*x + 5) - 2*x ≥ 3*x + 1 - 2*x
5 ≥ x + 1
Now we subtract 1 in both sides:
5 - 1 ≥ x + 1 - 1
4 ≥ x
