First subtract 4 from both sides to isolate the 3x.
That leaves us with 3x = -9.
Since x is being multiplied by 3, to get x by itself,
we need to divide both sides of the equation by 3.
So our final answer is x = -3.
Answer:
x = -3
Step-by-step explanation:
3x + 4= -5
Subtract 4 from both sides.
3x = -9
Divide both sides by 3.
x = -3
cheetah can run 70 miles per hour. What is this speed in feet per hour? *
Answer:
369600 feet per hour
Step-by-step explanation:
1m = 5280ft
5280 x 70 = 369600
Answer:
369,600 feet per hour
Step-by-step explanation:
1 mile = 5,280 feet
70 mph (cheetah's speed) x 5,280 feet (feet in 1 mile) = 369,600 feet (cheetah's speed in feet)

What is an equation of the line that passes through the point (8,2) and is parallel to the line x+4y=28
Answer:
y = -1/4x + 4
Step-by-step explanation:
x+4y=28
4y = -x + 28
y = -1/4x + 7
slope m = -1/4
Parallel lines have similar slope so we'll use -1/4 from above and given point (8,2) to find y-intercept.
y = mx +b
2 = -1/4(8) + b
2 = -2 + b
b = 4
Using m and b from above we can now form the new equation of line that is parallel to y = -1/4x + 7.
y = mx + b
y = -1/4x + 4

Write the steps to solving the following problem.
4 - 3x = -1
Step 1:
Step 2:
Step 1: Add 3x to both sides to get 4 = 3x - 1
Step 2: Add 1 to both sides to get 5 = 3x
Step 3: Divide by 3 on both sides to get 5/3 = x
Answer:
x = [tex]\frac{5}{3}[/tex] or [tex]1 \frac{2}{3}[/tex]
Step-by-step explanation:
Isolate the variable x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.
PEMDAS is the order of operation, and stands for:
Parenthesis
Exponents (& Roots)
Multiplication
Division
Addition
Subtraction.
~
Step 1:
Subtract 4 from both sides of the equation:
4 (-4) - 3x = -1 (-4)
-3x = -1 - 4
-3x = - 5
Step 2:
Divide -3 from both sides of the equation:
(-3x)/-3 = (-5)/-3
x = -5/-3
x = 5/3
x = 1 2/3

Answer:
A. 1.88
Step-by-step explanation:
In less fancy terms, a constant of proportionality is essentially a rate of change - or more specifically, a unit rate.
It's the number we multiply our independent variable by to get the y. You can find this by simply dividing the y value by the x value!
Let's choose the first order pair (2, 3.76).
[tex]3.76 \div 2 = 1.88[/tex]
We can check that this table IS constant by doing the same with the other values... we should always get 1.88!
[tex]7.52 \div 4 = 1.88\\9.40 \div 5 = 1.88\\15.04 \div 8 = 1.88[/tex]
This is true for all values - which means our constant is 1.88

Don claims that perpendicular lines are lines that intersect such that at least one of the angles is a right angle.
Determine whether each statement below justifies the claim. Select Yes or No for each statement.
Yes No
Intersecting lines allow for the creation of four angles with a common vertex.
O OD
If one of the angles is a right angle, the angle vertical to it must also be a right angle.
Because linear pairs are complementary, the remaining two angles must also be right angles. O

Answer:
Line s and Line t are parallel.
Step-by-step explanation:
Now, we know that angles 1 and 2 are congruent, because they have the same angle measures. Now, looking at their positions, we can see that they are alternate exterior angles.
By the converse of the Alternate Exterior Angle, (I do not remember exactly how the theorem went) if two lines are cut by a transversal and have congruent alternate exterior angles, then the lines are parallel. Using this theorem, we can find that lines s and t are parallel, because they are cut by a transversal and their alternate exterior angles are congruent.

5)A chef has 3 1/16
pounds of flour in his kitchen. He buys
another 6 1/2
pounds of flour. How much flour does he
have in all?
Answer:
9 9/16
Step-by-step explanation:
The first step is to find the LCD of 16 and 2
It is 16, and you can multiply the 6 1/2 by 8 which equals 6 8/16
Then you add
3 1/16 + 6 8/16 is equal to 9 9/16, which is your answer.
Hope this helped

Two trains are traveling at constant speeds on different tracks.
Answer:
Train B is traveling faster
Step-by-step explanation:
From the picture, we want to know which train is traveling faster
We can know this by knowing the speed of the trains
Mathematically;
speed = distance/time
Train A
12.5 m in 1 second
speed = 12.5/1 = 12.5 m/s
Train B
100 m in 4 seconds
speed = 100/4 = 25 m/s
So train B is traveling faster
This is because it covered a distance of 100 m in 4 seconds as opposed to train A which covered a distance of 12.5 m
in 1 second

What is the slope of a line perpendicular to the line whose equation is
12x – 3y = 81. Fully reduce your answer.
Answer:
slope of perpendicular line is -1/4
Step-by-step explanation:
slope of standard equation of line that is ax+ by = c is
slope m = -a/b
given equation is
12x – 3y = 81
comparing it with ax+ by = c
a = 12
b = -3
thus
slope of given line = -12/-3 = 4
we also know product of slope of two perpendicular line is -1
let the slope of other line be m
thus,
product of given line line and perpendicular line is -1
4*m = -1
m = -1/4
Thus,
slope of perpendicular line is -1/4
