which property of equality should you use to solve the equation for x? -3x = 21
A. The division property of equality
B. The subtraction property of equality
C. The addition property of equality
D. The multiplication property of equality
Answer:
A. The division property of equality
Step-by-step explanation:
To get x you need to find a way to get it by itself, which can be done by dividing -3 from both sides of the equation (which is the division property of equality).
For example,
-3x=21
/-3 /-3
x=21/-3
x=-7

Please help me find the perimeter for the composite figure.
Answer:
A 10.28in
Step-by-step explanation:
Find the perimeter of the circle first. Because there are two half-circles, you can just find the circumference of one whole circle. 2πr is the formula. r is the radius. The circumference of the circle is 2π or 6.28.
Then add the two sides of the square. It is 2+2=4. Add 6.28 and 4.

Step-by-step explanation:
If f(x)= 9x^2+2x-3, find f(-1).
Answer:
f(-1)= 4
Step-by-step explanation:
Just plug -1 into all Xs
and split it into 2 seperate problems for the time being
[9 times (-1)^2] + [2(-1)-3]
-1 squared is positive 1 times the 9 is just 9
Plus 2 times -1 is -2 minus 3 is -5
combine the two seperate problems you have
9-5 the subtract and
f(-1)= 4

Alek and Ann start walking around a track at the same time and at the same place. It takes Ann 6 minutes to walk around the track, and it takes Alek 8 minutes. After how many minutes will they reach the starting point at the same time
Answer:
3 3/7 minutes
Step-by-step explanation:
This calculated using the formula:
1/x + 1/y = 1/n
Where
x = Number of minutes it took Ann to walk = 6 minutes
y = Number of minutes it took Alek to walk = 8 minutes
n = Number of minutes it would take An and Alek to reach the starting point at the same time
1/6 + 1/8 = 1/n
Lowest Common Denominator = 24
4 + 3/24 = 1/n
7/24 = 1/n
Cross Multiply
7n = 24
n = 24/7
n = 3 3/7 minutes
It would take them 3 3/7 minutes to reach the starting point at the same time.

find the area of each sector shown (the shaded section)
Answer:
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].
Step-by-step explanation:
Area of a sector = (θ ÷ 360) [tex]\pi[/tex][tex]r^{2}[/tex]
where θ is the central angle of the sector, and r is the radius of the circle.
From the diagram give, diameter of the circle is 26 m. So that;
r = [tex]\frac{diameter}{2}[/tex]
= [tex]\frac{26}{2}[/tex] = 13 m
θ = 360 - (180 + 160)
= 360 - 340
= [tex]20^{o}[/tex]
Thus,
area of the given sector = [tex]\frac{20}{360}[/tex] x [tex]\frac{22}{7}[/tex] x [tex](13)^{2}[/tex]
= [tex]\frac{20}{360}[/tex] x x [tex]\frac{22}{7}[/tex] x 169
= 29.5079
The area of the sector (shaded section) is 29.51 [tex]m^{2}[/tex].

In the figure to the right, if AC = 21 and BC = 18, what is the
radius?
Triangle is missing, so i have attached it.
Answer:
Radius = 10.82
Step-by-step explanation:
From the image attached, the triangle is obviously a right angle triangle and therefore, the missing side (AB) which is the radius can be found via pythagoras theorem.
We are given;
AC = 21
BC = 18
Thus;
|AC|² = |AB|² + |BC|²
21² = |AB|² + 18²
|AB|² = 441 - 324
AB = √117
AB = 10.82

NEED ASAP Which line is parallel to the line y=4x-2?
Answer:
y = 4x + 1
Step-by-step explanation:
Given the equation y = 4x - 2, we need to find the equation parallel to this line. Note that for two equations to be parallel to each other, the must have the same slope
Standard form of an equation is y = mx + b
Compare;
mx = 4x
m = 4
Since the slope of the given equation is 4, the required equation must also have a slope of 4
Since we are not given an option, we can assume any equation with a slope of 4
y = 4x + 1 will be parallel to the given equation since they both have the same slope
Note that the equation can be different so far they have the slope of 4
what does 4x-2y=2 equal to step by step
Answer:
y = 2x - 1
Step-by-step explanation:
4x - 2y = 2
So I'm assuming that your goal is to solve for the value of y in terms of x
First: the whole equation can be divided by 2
2x - y = 1
Second: subtract 2x from both sides
-y = -2x + 1
Third: divide each side by -1
y = 2x - 1

Terry has 3 pairs of pants (black, khaki, and brown) and 4 shirts (yellow, red, blue, and white). He does not care which colors he wears together. How many different outfits can Terry make
Answer: 12 different outfits
===========================================================
Explanation:
We simply multiply the values given to us. Think of a table that has 3 rows and 4 columns. The rows represent the different colors of pants Terry can wear. Each column is a different color shirt. Since we have 3 rows and 4 columns, we have 3*4 = 12 cells inside the table. Each cell represents a combination of pants and shirt colors. This means there are 12 different outfits possible.
Answer:
12
Step-by-step explanation:
if he has 3 pairs of pants and doesn't care what colors he wears then each shirt can go with the pants once and since there a 4 shirts and three pants then 3 times 4 =12
The farmer walks by the pen with the chickens and pigs. He counts 18 heads and 50 feet. How many of each, chicken and pigs, are there?
Answer:
chickens = 11
pigs = 7
Step-by-step explanation:
this would be solved using simultaneous equation
let c = chicken .
p = pigs
A normal pig and chicken both have 1 head. thus :
c + p = 18 equation 1
A normal pig has 4 legs and a normal chicken has 2 legs. Thus
2c + 4p = 50 equation 2
multiply equation 1 by 2
2c + 2p = 36 equation 3
subtract equation 3 from 2
2p = 14
p = 7
substitute for p in equation 1
c + 7 = 18
c = 11
