x = -8
x = 3
x = -15
The explanation:
5x + 20 = 3x + 4
5x = 20 - 20 = 3x + 4 - 20
subtract = subtract = 5x = 3x - 16
5x = 3x - 16
5x - 3x = 3x - 16 - 3x
7x - 4 = 3x + 8
7x - 4 + 4 = 3x + 8 + 4
7x = 3x + 12
7x = 3x + 12
7x - 3x = 3x + 12 - 3x
2x + 6 = x - 9
2x + 6-6 = x - 9-6
2x = x - 15
2x = x - 15
2x - x = x - 15 - x
x = - 15
What does this equal to?
x=5/4 and y=15/16
hopefully this will help with your questions
5 Loni purchased a sweater with a regular price of $45.00. The sweater was on
sale for 20% off, and the sales tax rate is 8.25%. How much did Loni pay for the
sweater?
A $2.97
B $9.00
C $36.00
D $38.97
Answer:
D is correct
Step-by-step explanation:
First we find 20% of the price and subtract it
[tex]45*0.20=9\\45-9=36[/tex]
Next we find how much tax would be
[tex]36*0.0825=2.97[/tex]
then we add the two amounts together to get the final price
[tex]36+2.97=38.97[/tex]

There are two labeled weights of 4 grams and 12 grams. The three circles each have the same weight. what is the weight of each circle in grams? show your thinking
I think the right Answer 8/3
Answer:
8/3
Step-by-step explanation:
This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.
We have to determine,
What is the weight of each circle?
According to the question,
Let the weight of each circle be x.
This hanger is in balance. there are 2 labeled weights of 4 grams and 12 grams the 3 circles have the same weight.
The hanger is in the balanced state then the sum of all weight of the left-hand side is equal to the sum of all weight of the right-hand side.
Left hand side weight = x+ x + x+ 4 = 3x+4
Right hand side weight = 12
Then,
The hanger is in a balanced state, the weight of each circle is given by,
The weight of the left-hand side = the weight of the right-hand side
The value of x is 8/3.
Hence, The weight of each circle is 8/3.
HELP LOOK AT THE PIC ( Write the number of the vertices) I FORGOT THIS SINCE YEARS AGO
Answer:
3 vertices
Step-by-step explanation:
Vertices are the "points" of a 2D figure. In this case, we see the 2D figure as a triangle. There are 3 points on the triangle, so there are 3 vertices.
A tree is growing on a hill. In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a point 6 feet off the ground. The wire is anchored to the ground 10 feet from the base of the tree. At what angle is the tree growing in relation to the hill?.
The angle between the sides 6 feet and 10 feet is 93.82 degrees by using the cosine rule.
What is trigonometry?Trigonometry deals with the relationship between the sides and angles of a triangle.
A tree is growing on a hill.
In an attempt to make the tree grow straight up, a 12-foot-long wire is attached to a tree at a point 6 feet off the ground.
The wire is anchored to the ground 10 feet from the base of the tree.
We know that the cosine rule is given as
[tex]\rm Cos \theta = \dfrac{a^{2} +b^{2} - c^{2} }{2ab}[/tex]
We have
a = 6
b = 10
c = 12
Then angle will be
[tex]\rm Cos \theta = \dfrac{6^{2} +10^{2} - 12^{2} }{2*6*10}\\\\\rm Cos \theta = \dfrac{36+100-144}{120}\\\\\rm Cos \theta = \dfrac{-8}{120}\\\\\theta \ \ \ \ \ = cos^{-1} \dfrac{-8}{120} \\\\\theta \ \ \ \ \ = 93.82[/tex]

Show proportion and how to solve please
Answer:
x = 8
Step-by-step explanation:
In this geometry, all of the triangles are similar right triangles. That means corresponding sides are proportional. The proportion you write will express that relation for the sides you are given.
long side / short side = x/4 = 4/(x-6)
Multiplying this proportion by 4(x-6) gives ...
x(x -6) = 16

The float committee made a scale model of their float before they started construction. 1 inch = 3 feet to create their model. The actual float will be 18 feet long
It can be deduced from the scale computed that the model will be 648 inches.
How to solve the scaleSince 1 foot = 12 inch
18 feet = 12 × 18 = 216 inches.
In this case, since 1 inch = 3 feet was used to create their model, the model in their scenario will be:
= 216 × 3
= 648 inches.
In conclusion, the model is 648 inches.

PLEASE HELP I NEED TO MAKE A COMPOUND INEQUALITY (I ATTACHED THE IMAGE THIS TIME)
Answer:
I think you need to draw it with graph.
Step-by-step explanation:
Kareem plans to get eight hours of sleep but looses a half hour of sleep every time his dog barks. Therefore between his hours of sleep (h) and number of dog barks (b) will be:
h = 8 – (b/2)
So that if b = 0,
Kareem’s hours of sleep:
h = 8-(0/2)
= 8-0
= 8
if b = 5
h = 8 -(5/2)
h = (16-5)/2
h = 11/2
h = 5.5

Answer:
AD ≈ 80
Step-by-step explanation:
The Pythagorean theorem can be used to write and solve relations between the various edges and diagonals.
AE is the hypotenuse of ΔABE, so you have ...
AE² = AB² +BE²
BE² = AE² -AB² = 65 -52 = 13
__
AD is the hypotenuse of ΔACD. We presume the figure is a rectangular prism, so CD = BE. Then you have ...
AD² = AC² +CD²
AD² = 80² +13 = 6413 . . . . . CD² = BE² = 13
AD = √6413 ≈ 80.081
AD ≈ 80

Washer - 350$
Dryer - 300$
Total of these two items = 650$
1% of 650$ = 6.5$
$6.5 x 7.5% = 48.75
