Answer:
The answer is z = -2
Step-by-step explanation:
You combine like terms.
Then subtract 7z from both sides.
Add 10 to both sides.
Then divide both sides by -14. (28/-14)
Which then equals to -2
Select the fraction that is equivalent to A. 1 9 B. 1 2 C. 1 22 D. 2 9
Can someone tell me the answer plz I’ll give you brainlist and points only if you get it right
Answer:
Should be E.
Step-by-step explanation:
if u add and if u subtract 4 from both sides u get 1x=19,divide frmo both sides and x=19
One night a theater sold 548 movie tickets. An Adult’s ticket costs $6.50 and a child’s ticket cost $3.50. In all $2881 was taken in. How many of each kind of ticket were sold?
Step-by-step explanation:
let x be the number of adults and y the number of childrens
x+y=548 people because thats the whole number of sold tickets
and
6.50*x+3.50*y=2881 dollars in total
let separate x from the first formula
x=548-y
and replace it at the second equation
6.50*(548-y)+3.50y=2881
6.50*548-6.50y+3.50y=2881
3562-3y=2881
3y=681
y=227
so x=548-y=548-227=321
there were sold 321 adult tickets and 227 child's tickets.
The coordinates for the vertices are A(1,3), B(4,0) ,C(1,-3) ,D(-2,0) what is the length of the AB
Answer: 3sqrt(2)
Step-by-step explanation:
d = sqrt[(3-0)^2 + (4-1)^2]
d = sqrt[9+9]
d = sqrt(18) = 3sqrt(2)
which statement is true and represent the correct form of scientific notation
A. 5.3 x [tex]10^{-2}[/tex] = -0.053
B. 2 x [tex]10^{4}[/tex] < 20,000
C.-74.308 < -0.74 x [tex]10^{3}[/tex]
D. 12,000,000 = 1.2 x [tex]10^{7}[/tex]
Step-by-step explanation:
let express them in the same form
5.3*1/100=0.053>-0.053 so A is false
2*10^4=2*10000=20,000 is equal to 20,000 so even B is false
-0.74*10^3=-0.74*1000=-740<-74.308 so even C is false
lets see D
1.2*10^7=12*10^6=12*1000000=12,000,000 which is equal to 12,000,000 so D is true

5-y=-3x in standard form
Answer:
y = 3x + 5
Step-by-step explanation:
The linear formula follows this general form: y = mx + c
Hence, to put 5-y=-3x in standard form, you would rearrange it
-y = -3x - 5
y = 3x + 5
Answer:
3x-y=-5
Step-by-step explanation:
standard form is Ax + By = C
5-y=-3x move the y to the other side by adding it to the -3x
-3x+y=5 The x cant be negative so switch all the signs
3x-y=-5

Answer:
C
Step-by-step explanation:
21 - (-5) A negative minus a negitive turns into a +
21 + 5 = 26
A. -21 + 5 = -16 NO
B. 21 - 5 = 16 NO
C. 21 + 5 = 26 YES
D. -21 - 5 = -26 NO
Answer:
C
Step-by-step explanation:
When subtracting a negative, the two negatives cancel out. The rule is that two like signs become positive.
Therefore, +(+) =+ and -(-) = +
So, the equation would be 21 + 5.
A line has a slope of 1/4 and passes through the point (0.2. 4/5).
Find the value of b, the y-intercept.
b=
Answer:
The value of the y-intercept b is 0.75
Step-by-step explanation:
Here, we want to find the value of the y-intercept
The equation of the line can be written as;
y = mx + b
where m is slope and b is the y-intercept
so y = 1/4x + c
To get the value of b , we substitute for x and y using the given point
4/5 = 1/4(0.2) + c
Multiply
0.8 = (0.25)(0.2) + b
0.8 = 0.05 + b
b = 0.8 - 0.05 = 0.75
Answer:
b=0.75

What are the steps for using a compass and straightedge to construct a line through point X that is parallel to line r?
Answer:
What are the steps for using a compass and straightedge to construct a line through point X that is parallel to line r? Drag the steps and drop them in order from start to finish. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.
Step-by-step explanation:
Answer:
1. Use the straightedge to draw a line s that passes through X and intersects line r. Label the point of intersection as point Y.
2. Place the point of the compass on point Y and draw an arc that intersects lines r and s. Label the intersections as points M and N.
3. Without changing the width of the compass opening, place the point of the compass on point X and draw an arc that intersects line s. Label the intersection as point P.
4. Place the point of the compass on point M and open it to width MN.
5. With the compass opening set to width MN, place the point of the compass on point P and draw an arc that intersects the arc that was drawn from point X. Label the intersection of the arcs as point Z.
6. Use the straightedge to draw XZ.

An item is priced at $13.51. If the sales tax is 7%, what does the item cost including sales tax? please help ♀️♀️
Answer:
14.45
Step-by-step explanation:
There are two approaches to solving the equation -3x + 10 = 4x - 20
Subtract 4x from both sides. OR Add 3x to both sides.
–7x + 10 = –20 OR 10 = 7x – 20
Solve the equation using both approaches.

The amount of Social Security benefits received by an individual that he or she must include in gross income:
a. May not exceed the portion contributed by the employer.
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
c. May not exceed 50% of the Social Security benefits received.
d. Is computed in the same manner as an annuity [exclusion = (cost/expected return) × amount received].
e. None of these choices are correct.
Answer:
b. May be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
Step-by-step explanation:
Social security measures an organization to guarantee individuals against certain risks (social risks). Social security is made up of a set of institutions whose function is to protect individuals from the consequences of various events or situations, generally referred to as social risks.
Social Security is a public service of the State, ensuring all the social risks of workers, employees, liberal professions, self-employed, and non-salaried workers. Social Security provides the benefits provided by the Social Security Code. However, the amount of Social Security benefits received by an individual that they must include in gross income may be zero or as much as 85% of the Social Security benefits received, depending upon the taxpayer's Social Security benefits and other income.
