Answer:
B) Chemical Change
Step-by-step explanation:
Physical change only changes the physical appearance of good, their chemical properties remaining same. These are usually reversible. Eg : Cutting a cake
Chemical change changes the physical composition of the product(s) involved. These are usually not irreversible. Eg : Baking of a cake, getting bubbles during bake process meanwhile
x-5
x+3
What are the restrictions?
Let's simplify step-by-step. Sowwy im late
x- 5x + 3
= x + - 5x + 3
combine like terms:
= x + - 5x + 3
= (x + - 5x + (3)
= -4x + 3

Lila thought of a whole number and added the next whole number to it. What was the original number she thought of if the sum was 22?
Answer:
10Step-by-step explanation:
Let the original whole number be x and the next whole number be x+2
If Lila added both number and the sum was 22, then:
x + (x+2) = 22
x+x+2 = 22
2x +2 = 22
2x = 22-2
2x = 20
divide both sides by 2
2x/2 = 20/2
x = 10
Hence the original number she thought of was 10

Answer:
Angle WST = 91°
Step-by-step explanation:
The first step in this situation is to find Angle TSU. Then find x, which is 7, which can be put into the equation shown for Angle WST.
Nes and m are intersected by transversal t. ∥ m. Lines l and m are horizontal with l above m and intersected by transveral t. Angles 1, 2, 3, and 4 are formed where t intersects l with 1 and 3 above l from left to right and 2 and 4 below it. Angles 5, 6, 7, and 8 are formed where t intersects m with angles 5 and 7 above line m from left to right and 6 and 8 below it. Select all the angles that are supplementary to ∠4.
Answer:
The supplementary angles to ∠4 are;
∠3, ∠2, ∠7, ∠6, and ∠5
Step-by-step explanation:
The given information are;
The angular orientation of lines l and m = horizontal lines
Therefore l and m are parallel lines
The transversal line to lines l and m = Line t
Therefore, we have;
Angles between line t and line l = 1, 2, 3, and 4
The order of arrangement of the angles between line t and line l are from top left in a clockwise order;
1, 3, 4, and 2
Similarly, the order of arrangement of the the angles between the transversal t and the line m are from top left in a clockwise order;
5, 7, 8, and 6
Therefore, we have;
The supplementary angles to ∠4 are;
∠3, ∠2, ∠7, ∠6, and ∠5
∠3 and ∠4, ∠4, and ∠2, angles on a straight line between lines l and t
∠4 and ∠7 are opposite interior angles (Opposite interior angles are supplementary)
∠7 ≅ ∠6, ∠7 and ∠6 are alternate angles (
∠7 = ∠6 Definition of congruency
∴ ∠4 and ∠6 are supplementary (Transitive property)
∠4 and ∠5 are alternate interior angles (Alternate interior angles are supplementary).

1/2r + 2 (3/4r - 1) = 1/4r + 6
Answer:
r=32/7
Step-by-step explanation:
Let's solve your equation step-by-step.
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
Step 1: Simplify both sides of the equation.
1/2r + 2 (3/4r - 1) = 1/4r + 6
1/2r+(2)(3/4r)+(2)(-1)=1/4r+6(Distribute)
1/2r+3/2r+-2=1/4r+6
(1/2r+3/2r)+(-2)=1/4r+6(Combine Like Terms)
2r+-2=1/4r+6
2r-2=1/4r+6
Step 2: Subtract 1/4r from both sides.
2r-2-1/4r=14r+6-14r
7/4r-2=6
Step 3: Add 2 to both sides.
7/4r-2+2=6+2
7/4r=8
Step 4: Multiply both sides by 4/7.
(4/7)*(7/4r)=(4/7)*(8)
r=32/7
Answer: r=32/7

The simple interest formula is I = Prt, where I represents simple interest on an amount, P, for t years at a rate of r, where r is expressed as a decimal. What is the amount of money, P, that will generate $40 in interest at a 10% interest rate over 5 years?
Answer:
$80
Step-by-step explanation:
From the question, we are given The simple interest formula as I = Prt,
where l = simple interest on an amount= $40
t= years=5years
at a rate r= 10%
The rate= 10/100= 0.1
Then since we are looking for P, we can make P subject of formula from this expression;
I = Prt
P=I/rt
P= 40/(0.1 ×5)
P= 40/0.5
P= 80
therefore, the amount of money p that is needed is $80
Answer:
the answer would be $80. :)
Step-by-step explanation:
7w+7=-4+4w+23 what is this?
Answer: 7w+7=-4+4w+23 = W = 4
First you have to simplify the equations
7w+7= (4w) + (-4+23) 7w+7= 4w+19
Than you have to subtract the 4w (both equation)
7w+7-4w =4w = 4w + 19 - 4w = 3w+7= 19
And than you have to subtract the sevens
3w+7-7=19-7=3w=12
than divide by 3
3w/3 equals 12/3w=4

a worker uses 450 inches of steel wire to make 300 springs of the same size. at this rate how many inches of steel wire are needed to make 1 spring?
Answer:
D
Step-by-step explanation:
You divide the 450 inches of steel by the 300 springs to get 1.5 or 1 1/2
a trick to have a better idea is that if the number that is being divided is larger than the number you are dividing by, the answer will always be greater than one.
Regal Cinemas sold a total of 8500 movie tickets. Proceeds totaled $64,600. Tickets can be bought in one of 3 ways: a matinee admission cost $5, student's admission is $6 all day, and regular admission are $8.50. How many matinee tickets were sold if twice as many student tickets were sold as matinee tickets? * Only type the number of matinee tickets that were sold
Answer:
900
Step-by-step explanation:
From the information given you can write the following equations:
x+y+z=8500 (1)
5x+6y+8.50z=64600 (2)
y=2x (3)
First, you can replace (3) in (2) and (1):
x+2x+z=8500
3x+z= 8500 (4)
5x+6(2x)+8.50z=64600
5x+12x+8.50z=64600
17x+8.50z=64600 (5)
Now, you have two equations:
3x+z= 8500 (4)
17x+8.50z=64600 (5)
Then, you can isolate z in (4):
z=8500-3x (6)
Next, you can replace (6) in (5):
17x+8.50(8500-3x)=64600
17x+72250-25.5x=64600
7650=8.5x
x=7650/8.5
x=900
You can replace the value of x in (3) to find y:
y=2x
y=2*900
y=1800
Finally, you can replace the value of x in (6) to find z:
z=8500-3(900)
z=8500-2700
z=5800
According to this, the answer is that 900 matinee tickets were sold.
