Answer:
Step-by-step explanation:
3. 10x + 6 = 8x
8x = 10x + 6
-2x = 6
x = -3
4. y = 8(1) - 5= 8 - 5 = 3
y = 8(2) - 5 = 16 - 5 = 11
y = 8(5) - 5 = 40 - 5 = 35
y = 8(0) - 5 = 0 - 5 = -5
y = 8(-1) - 5 = -8 - 5 = -13
[tex]10x + 6 = 8x[/tex]
[tex]6 = 8x - 10x[/tex]
[tex]6 = - 2x[/tex]
[tex]6 \div - 2 = x[/tex]
[tex] - 3 = x[/tex]
Number 4 :[tex]y = 8x - 5[/tex]
When [tex] x = 1, y = \bold{ 3} [/tex]
[tex]y = (8 \times 1)- 5[/tex]
[tex]y = 8 - 5[/tex]
[tex]y = 3[/tex]
When [tex] x = 2, y = \bold{ 11} [/tex]
[tex]y = (8 \times 2)- 5[/tex]
[tex]y = 16 - 5[/tex]
[tex]y = 11[/tex]
When [tex] x = 5, y = \bold{35} [/tex]
[tex]y = (8 \times 5)- 5[/tex]
[tex]y = 40 - 5[/tex]
[tex]y = 35[/tex]
When [tex] x = 0, y = \bold{-5} [/tex]
[tex]y = (8 \times 0)- 5[/tex]
[tex]y = 0 - 5[/tex]
[tex]y = - 5[/tex]
When [tex] x = -1, y = \bold{-13} [/tex]
[tex]y = (8 \times - 1)- 5[/tex]
[tex]y = - 8 - 5[/tex]
[tex]y = - 13[/tex]
How do i solve for this?
9514 1404 393
Answer:
97.42 square units
Step-by-step explanation:
The area of a sector is given by ...
A = (1/2)r²θ
where r is the radius (12.2) and θ is the central angle in radians. Here, you're given the central angle as 75°, so you need to convert that to radians.
75° = (75°)×(π/180°) radians = (5/12)π radians
Then the area is ...
A = (1/2)(12.2²)(5π/12) = 744.2π/24 ≈ 97.42 . . . square units
__
Equivalently, you can find the area of the circle in the usual way:
A = πr² = π(12.2²) ≈ 467.59465
Then, multiply by the fraction of the circle that is shaded (75°/360°)
sector area = (467.59465)(75/360) = 94.42 . . . square units

I think it is 13/15 (0,8666666...) but I am not sure
Answer:
12/15 or if u simplify it then you'll get 4/5
Step-by-step explanation:
3 2/3 multiplied by 5 bc u would need to find an equivalent fraction then 3 2/3 will turn into 55/ 15 and 2 4/5 will be multiplied by 3 and turned into 43/15. After that then u would substract 55/15 by 43/15 and u will end up with 12/15 and if simplified then it would be 4/5

The ratio of the length to the width of the rectangle is 10:6. Of the perimeter of the rectangle is 160 meters, find the measure of the width. Show your work
Answer:
60 meters, see explanation.
Step-by-step explanation:
We know that the ratio of length : width is 10 : 6. So for every 10 meters of length, we also have 6 meters of width. This problem is much easier since we are given the P = 160 meters.
You can see that if we multiply the ratio by ten, we get 100 : 60, where 100 + 60 = 160 total meters. From here, it is clear that the width would be 60 meters.

Step-by-step explanation:
The student council at Oxford High School is making T-shirts to sell for a fundraiser, at a price of $12 apiece. The costs, meanwhile, are $10 per shirt, plus a setup fee of $130. Selling a certain number of shirts will allow the student council to cover their costs. How many shirts must be sold? What will the costs be?
Answer:
Number of shirts to breakeven = 65 shirtsCost of breakeven shirts = $650Step-by-step explanation:
First find the profit they will make from each shirt:
= Selling price - Cost price
= 12 - 10
= $2
They need to cover the cost of setting up which is $130. The number of shirts to sell given a profit of $2 from each shirt is:
= 130 / 2
=65 shirts
Cost of selling 65 shirts:
= 65 * 10 per shirt
= $650

angles and triangles
Answer:
x=120
y=60
z=60
Step-by-step explanation:
Recall that two angles are complementary if the sum of their measures is 90°. Find the measures of two complementary angles if one angle is 6º more than three times the other angle.
Answer:
The two angles are 69° and 21°.
Step-by-step explanation:
Write out the expression:
let x and y be two angles that are complementary and the sum of their measures is 90°
-> x° + y° = 90°
if one angle is 6º more than three times the other angle:
-> x° = 6° +3y°
Plug x = 6+3y into x° + y° = 90°
6° + 3y° + y° = 90°
Solve for y
4y° = 84°
y° = 21°
Plug y into x° + y° = 90°
x° + 21° = 90°
Solve for x°
x° = 90° - 21° = 69°
Given f(x) = -3x + 5, solve for x when f(x) = -4
Answer:

A strange bowling bow is made up of plastic and wood. The weight of the two materials are in a ratio of 5 to 9 if the bowling ball weights 238 ounces what is the weight of the plastic.
Answer:
85 ounces
Step-by-step explanation:
A strange bowling bow is made up of plastic and wood. The weight of the two materials are in a ratio of 5 to 9 if the bowling ball weights 238 ounces what is the weight of the plastic.
We are given the ratio:
Plastic : wood
5:9
Sum of proportion = 5 + 9 = 14
The weight of the bowling ball = 238 ounces
Hence
The weight of the plastic is calculated as:
5/14 × 238 ounces
= 85 ounces

Jan is not correct. The opposite of any number will not always be a positive. This is because the opposite of a positive number is negative and the opposite of a negative number is positive.
Basically, opposite numbers are numbers that are the same distance to 0 on a number line. If we were to have a positive 1, the opposite of that number would be a -1, because that's equally distant from 0 on a number line.

Find the perimeter of the triangle whose vertices are the following specified points in the plane.
(5,6), (4,1) and (-4,2)
Answer:
23 units
Step-by-step explanation:
Let the vertices of the triangle be A(5,6), B(4,1) and C(-4,2)
Perimeter of the triangle = AB + AC + BC
AB = √(5-4)²+(6-1)²
AB = √1²+5²
AB = √1+25
AB = √26
For BC where B(4,1) and C(-4,2)
BC = √(4-+4)²+(1-2)²
BC = √8²+1²
BC = √64+1
BC = √65
For AC where A(5,6) and C(-4,2)
AC = √(5+4)²+(6-2)²
AC = √9²+4²
AC = √81+16
AC = √97
Perimeter = √97 + √26 + √65
Perimeter = 9.85+5.09+8.06
Perimeter = 23
Hence the perimeter of the triangle is approx 23 units

Olivia does chores every Saturday morning. She spends of her time cleaning her room. Of the remaining of her time, she spends of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?
Answer:
4/7 of her total time cleaning the kitchen
Step-by-step explanation:
Olivia does chores every Saturday morning. She spends 1/3 of her time cleaning her room. Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen. How much of Olivia's total time does she spend cleaning the kitchen?]
Let
x = her total time
Room cleaning = 1/3x
Time remaining = 2/3x
Of the remaining 2/3 of her time, she spends 6/7 of it cleaning the kitchen.
Kitchen cleaning = 6/7 of 2/3x
= 6/7 * 2/3x
= (6*2)x/(7*3)
= 12/21x
= 4/7x
Olivia spent 4/7 of her total time cleaning the kitchen

Solve by Substitution. Find the ordered pair
7x – 2y = 1
2y = x - 1
Solution (x,y)
I need help can someone help me please????
Answer:
on the bottom equation you can subtract 1 from both sides, x = 2y+1 so you substitute that in for x on the other equation, 7(2y+1) - 2y = 1 or 14y + 7 -2y = 1 then 12y = -6 y = -1/2 which you put back into the other equation, 2(-1/2) = x -1 so -1 = x - 1 then x = 0, the answer is (0, -1/2)
Which of the following is not one of Euclid’s postulates?
1.) A circle may be described with any given point as its center and any distance as its radius.
2.) All right angles are congruent.
3.) All complementary angles form a right angle.
4.) A straight line may be drawn from any given point to any other.
Answer:
3.) All complementary angles form a right angle.
hope this helps you :)
"All complementary angles form a right angle" is not Euclid's postulates. Therefore, option C is the correct answer.
We need to identify which of the given option is not one of Euclid’s postulates.
What are Euclid’s postulates?A statement, also known as an axiom, is taken to be true without proof. Postulates are the basic structure from which lemmas and theorems are derived. The whole of Euclidean geometry, for example, is based on five postulates known as Euclid's postulates.
Postulate 1: A straight line may be drawn from any one point to any other point.
Postulate 2:A terminated line can be produced indefinitely.
Postulate 3: A circle can be drawn with any centre and any radius. Postulate 4: All right angles are equal to one another.
From the about options we can draw a conclusion that "All complementary angles form a right angle" is not Euclid's postulates.
Therefore, option C is the correct answer.

-4x+35>2
Answer:
I don't know........................
Answer:
x < 33/4
Step-by-step explanation:
1.) -4x+35 > 2 (Move the constant to the right-hand scale side and change its sign)
-4x > 2 - 35
2.) -4x > 2 - 35 (Calculate the difference)
4x > -33
3.) -4x > -33 (Divide both sides of the inequality by -4 and flip the inequality sign)
