Answer:
n = -5
Step-by-step explanation:
n - 4 = 3n + 6
n = 3n + 10
-2n = 10
n = -5
Answer:
-5
Step-by-step explanation:
Lets start by combining some common terms. -4 can be brought over to the right as +4 and 3n can be brought to the left as -3n to make the statement -3n +n = 6+4
Simplifying that, we get -2n = 10
Dividing 10 by -2, we get n = -5

It takes Susana 10 seconds to complete 5 math
problems. How many math facts can she complete
in 35 seconds?
Answer:
If you understand what I wrote you can get the answer.
Step-by-step explanation:
First find how long it takes her for each problem which is 10 seconds / 5 problems = 2 seconds per problem. Then take 35 seconds and divide it by 2 seconds which gives the number of problems she did in 35 seconds.

Jessie read three books in one week. At this rate, how many books will she read in 3 weeks?
Answer:
Jessie will read 9 books in 3 weeks.
Step-by-step explanation:
3 x 3 = 9
Answer: 9
Step-by-step explanation: If you need an equation, you can create one:
t = total number of books read
w = weeks
t = 3w
The 3 is there because she reads 3 books weekly, so you multiply the number of weeks by the number of books she reads.
Plug in 3 weeks:
t = 3(3)
t = 9 books
Jessie reads 9 books in 3 weeks.

Complete Question
The Henderson Hawks minor-league baseball team is giving away baseballs an
game. The balls cost $3 each and the towels cost $2 each. The team wants to give away 200 items and have 500 to spend. How many of each item should the team give away Show your
work or explain your reasoning.
Answer:
They should give away 100 balls and 100 towels
Step-by-step explanation:
Let the number of balls = x
Let the number of towels = y
x + y = 200........ Equation 1
y = 200 - x
$3 × x + $2 × y = $5000
3x + 2y = 5000...... Equation 2
3x + 2(200 - x)= 5000
3x + 400 - 2x = 5000
Collect like terms
3x - 2x = 500 - 400
x = 100
Number of balls to be given away = 100
Note:
y = 200 - x
y = 200 - 100
y = 100
Number of towels to be given away = 100
Therefore, they should give away 100 balls and 100 towels

x = 3y +7
3x + 4y = 8
Answer:
x=4, y=-1
Step-by-step explanation:
x=3y +7. equation 1
3x+4y=8. equation 2
substitute equation 1 into equation 2
3 (3y +7)+4y =8
9y+21+4y=8
13y+ 21=8
13y=8-21
y=-13/13
y=-1
substitute the value of y into equation 1
x=3(-1)+7
x=-3+7

A toy glider plane is launched from a height of 50 feet above the ground. If the plane descends at a constant rate of 1.3 feet per second, then its height, in feet, after s seconds can be found using the equation h = 50-1.3s. Use the equation to find the height of the glider 9 seconds after it was launched.
Answer:
38.3 feet
Step-by-step explanation:
h=50-1.3(9)
h=50-11.7
h=38.3

Which values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 onlyWhich values from this set {−36, −32, −16, 0, 4, 16} satisfy this inequality? −14x+6≥14 −32, −16, 0, 4, and 16 only 0, 4, and 16 only −36, −32, and −16 only −36 and −32 only
Answer:
Step-by-step explanation:
Given the inequality −14x+6≥14, we are to find the range of x that will make the inequality true.
Given −14x+6≥14
Subtract 6 from both sides.
−14x+6-6≥14-6
-14x≥8
-7x≥4
Multiply both sides by -1
-(-7)x≤-4
7x ≤ -4
x≤-4/7
This shows that the values of x is always less than or equal to -0.57
Hence the values less tan the value of x in the inequality are -36, -32 and -16

f(x) = 2x^2+ 6 when f (4)
Find the value of x
Answer:
134 degrees
Step-by-step explanation:
the angles in a triangle always add up to 180.
86+48=134
to find the last angle you subtract 180-134
this gives you 46 degrees
a straight line is always measured as 180 degrees.
180-46=134
so x=134 degrees

PLEASE SHOW STEPS.
(Brainliest is going to be given once 2 people answer.)
# 12 Points
solve for y first
2y=12-6×
divide each term by 2 and simplify
y=6-3x
Answer:
y=6-3x
Step-by-step explanation:
6x+2y=12
6x+2y=12 divide all by 2
3x+y=6 subtract 3x from both sides
y=6-3x

how do you solve inequalities and how do you graph them?
Answer:
Graph a Linear Inequality
Step-by-step explanation:
Rearrange the equation so "y" is on the left and everything else on the right.
Plot the "y=" line (make it a solid line for y≤ or y≥, and a dashed line for y< or y>)
Shade above the line for a "greater than" (y> or y≥) or below the line for a "less than" (y< or y≤).
