and the 5 dollars could be 4 x 5 add them up and your answer should be right
By using distributive property of multiplication over subtraction we got 4 (5.97) = 23.88 without actually multiplying 4 (5.97) .
What is distributive property of multiplication?This property states that when a number is multiplied by addition/subtraction of two number is same as multiplying this number with both the numbers individually and then adding/subtracting them.
let a, b, c are three numbers then distributive property of multiplication can be stated as :
a×(b ± c) =(a× b) ± (a ×c)
For Multiplying 4($5.97)
Write 5.97 = 6 -0.03
4 (5.97) = 4* ( 6 -0.03) = (4*6) -(4*0.03) (using distributive property)
⇒(4*6) -(4*0.03) = 24 - 0.12 = 23.88
Therefore without actually multiplying 4 (5.97) we got 4 (5.97) = 23.88 by using distributive property of multiplication over subtraction.

At the end of a snow storm, Elijah saw there was a lot of snow on his front lawn. The temperature increased and the snow began to melt at a steady rate. There was a depth of 18 inches of snow on the lawn when the storm ended and then it started melting at a rate of 1.5 inches per hour. Write an equation for S, in terms of t, representing the depth of snow on Elijah's lawn, in inches, t hours after the snow stopped falling.
Answer:
S = 18 - 1.5t
Step-by-step explanation:
The initial value is 18 inches
The rate of change is -1.5 inches per hour
t is the number of hours
S = 18 - 1.5t

HELP!
Answer:
<2, <5, and <7.
Step-by-step explanation:
<2 and 72°, are vertical angles. Vertical angles are congruent. Therefore, <2 ≅ 72°.
<7 and 72° are corresponding angles. Corresponding angles are congruent, therefore, <7 ≅ 72°.
<5 and 72° are alternate interior angles. Alternate interior angles are congruent, therefore, <5 ≅ 72°.
Angles that are congruent to 72° are <2, <5, and <7.
Given that ∠2 ≅ ∠6.
Which theorem proves that line d is parallel to line e.
Alternate interior angle theorem
Converse of the alternate interior angle theorem
Alternate Exterior angle theorem
Converse of the alternate exterior angle theorem
Answer:
Converse of the alternate exterior angle theorem
Step-by-step explanation:
just took the test ;)
The theorem that proves that lines d and e are parallel to each other, given that <2 is congruent to <6 is: D. Converse of the alternate exterior angle theorem
When a transversal cuts across two parallel lines, there are special angles formed having relationship with each other.
For two lines to be parallel, such relationship must exist. That is what a converse theorem seeks to prove.
We are told that <2 is congruent to <6.Both angles are exterior angles that also lie opposite each other along the transversal. That makes them alternate exterior angles.<2 will be congruent to <6 if lines d and le are parallel to each other.Therefore, the theorem that proves that lines d and e are parallel to each other, given that <2 is congruent to <6 is: D.

Answer:
X= -10
Step-by-step explanation:
Answer:
Angle Relationship: Alternate exterior angles
x = -10
Angle measurement: 51 °
Step-by-step explanation:
These angles are located "outside" the two parallel lines but on opposite sides of the transversal, therefore they are alternate exterior angles.
Alternate exterior angles are congruent, therefore the angle must be 51 °
51 = 61 + x
subtract 61 from both sides

1. Karen has a square cartolina whose sides measure 60
cm each. She cuts the cartolina into two equal rectangles.
Find the perimeter of one piece of rectangle.
2. A rectangle has a length of 30 cm and a width smaller
by 5 cm. What is its perimeter?
If Karen cut her square cardboard into two equal rectangles, the perimeter of those rectangles is 180cm. On the other hand, if the rectangle is 25 cm wide, the perimeter would be 110 cm.
What is the perimeter of a geometric figure?
The perimeter of a geometric figure is the measure of the length of all its sides. In this case, if Karen has a square of cardboard with a side of 60cm, it can be inferred that she would have two rectangles with a height of 30cm and a base of 60cm, so the perimeter would be:
30cm + 60cm + 30cm + 60cm = 180cmOn the other hand, if the rectangle has a base of 30cm and a height of 25cm, the perimeter would be:
25cm + 30cm + 25cm + 30cm = 110cmLearn more about perimeter in: https://brainly.com/question/6465134

A pre-paid cell phone plan has a flat rate of $15 with an additional cost of $0.15 per
minute. At most, how many minutes can Chelsea purchase if she has $35?
Write an inequality for this statement, write out 3 values that would make the inequality true
Answer:
anything less than 133 would be true
Step-by-step explanation:
35 ≥ 0.15m + 15
solve for m
subtract 15 from both sides
20 ≥ 0.15m
divide both sides by 0.15
133.33 ≥ m
m cannot be more than 133 minutes
Yara have two rectangular gardens in her backyard the smaller garden is 1/2 foot long and 2/3 foot wide the larger Garden is 4 feet long and 5 feet wide what is the area of the small garden in square feet what is the area of the large garden in square feet
Given that :
Area of a rectangle is : A = l×b
For smaller garden,
Length, l = [tex]\dfrac{1}{2}\ \text{foot}[/tex]
Width, [tex]b=\dfrac{2}{3}\ \text{foot}[/tex]
Area of a smaller garden is :
[tex]A=\dfrac{1}{2}\times \dfrac{2}{3}\\\\A=0.34\ \text{foot}^2[/tex]
For larger garden,
length, l' = 4 feet
Width, b' = 5 feet
Area of a larger garden is :
[tex]A'=l'\times b'\\\\A'=4\times 5\\\\A'=20\ \text{feet}^2[/tex]
So, the area of a smaller garden is 0.34 sq ft and that of a larger garden is 20 sq ft.

Nancy made 20 ounces of a snack mix that was 1/5 peanuts, 30% raisins, and 5 ounces of chocolate chips. the rest was granola how many ounces of granola were in Nancy's snack mix?
Answer:
5
Step-by-step explanation:
First of all, we have a lot of different forms of part/whole's. We have a fraction, a percentage, and a number. How do we make this work???
Let's convert our percent and fraction to ounces, because that is what the question is talking about.
1/5 of 20
1/5=x/20
20=5x
/5 /5
4=x
Now lets convert our percent into ounces.
30% of 20
30/100=x/20
30(20)=100x
600=100x
/100 /100
6=x
Now we have our ounces, we now need to find what is the granola. To do that, we need to add the number of everything else, and then subtract that by the total ounces.
4+6+5=15
20-15=5
The answer would be 5 ounces of granola!

This figure has two intersecting lines and a ray. What is the value of x?
108°
72°
19°
37°
Answer: The answer is 37
Step-by-step explanation:
If you subtract 71 from 108 the answer is 37
Since the angles of (x + 71)º is opposite to the same vertex to the angle of 108º, it is found that x = 37º.
The ray generated two angles, xº and 71º.Adding these angles, there is an angle of (x + 71)º, which is opposite to the same vertex to the angle of 108º, meaning that they have the same measure.
Applying the equality:
[tex]x + 71 = 108[/tex]
[tex]x = 108 - 71[/tex]
[tex]x = 37[/tex]
Thus, x = 37º.
