Answer:
x=-6
Step-by-step explanation:
use distributive property on the () and times x and 1 by three
then you subtract 6 from both sides
then subtract three from both sides
then divide both sides by 3
your work would look like this:
3(x+1)+6=-9
3x+3+6=-9
3x+3=-15
3x=-18
x=-6
Hope this helps!
Answer:
X=6
Step-by-step explanation:
3(x+1)+6=−9
Step 1: Simplify both sides of the equation.
3(x+1)+69(3)(x)+(3)(1)+6=−9
(Distribute)
3x+3+6=−9(3x)+(3+6)=−9
(Combine Like Terms)
3x+9=−93x+9=−9
Step 2: Subtract 9 from both sides.
3x+9−9=−9−93x=−18
Step 3: Divide both sides by 3.
3x3=−18/3
x=−6

A bird leaves its nest and travels 15 miles per hour downwind for x hours. On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
a. What is the distance of the entire trip?
miles
b. How long does the entire trip take?
_hours
_minutes and
_seconds
Answer:
A)
10 miles.
B)
0 hours, 40 minutes, and 0 seconds.
Step-by-step explanation:
Remember that distance is given by the formula:
[tex]d=st[/tex]
Where d is the distance, s is the speed, and t is the time.
We know that the bird leaves its nest and travels 15 miles per hour for x hours. So, let's substitute 15 for s and x for t:
[tex]d=15x[/tex]
On the return trip, the bird travels 3 miles per hour slower and has 2 miles left after x hours.
Since this is the return trip, the distance d remains the same. We know that the bird travels 3 miles per hour slower, so it's speed is 15-3 or 12 miles per hour.
However, after x hours, it still has 2 miles left until reaching the destination. So, we will subtract 2 from d. This gives us the equation:
[tex]d-2=12x[/tex]
We can solve this using substitution. Since we already know that d is 15x. Substitute:
[tex]15x-2=12x[/tex]
Solve for x. Subtract 12x from both sides:
[tex]3x-2=0[/tex]
Add 2 to both sides:
[tex]3x=2[/tex]
Divide both sides by 3:
[tex]x=2/3[/tex]
Therefore, the bird traveled for a total of 2/3 hours or 40 minutes.
And the distance the bird traveled is:
[tex]d=15x[/tex]
Substitute 2/3 for x to get:
[tex]d=15(2/3)=30/3=10\text{ miles}[/tex]
And we're done!
which expressions are equal to 3/5 × 6
a. 3 × ( 6 ÷ 5 )
b. 3 ÷ (5 × 6 )
c. ( 3 × 6 ) ÷ 5
d. 3 × 6/5
Answer:
A & C & D
Step-by-step explanation:
A & C & D both show the commutative property of multiplication and therefore is the correct answer because 3/5(6) = 18/5 and 3(6/5) is also 18/5.
3 x (6÷5) is also 18/5
(3×6)÷5 is also 18/5
Given the following two points write the equation in slope intercept form: (0, -5) and (4, 3)
Answer:
[tex]y=2x-5[/tex]
Step-by-step explanation:
Let's start by finding the slope using the two points given. Use the formula for slope below:
[tex]m=\frac{y_2-y_1}{x_2-x_1}[/tex]
Identify your values:
[tex]x_1=0\\x_2=4\\y_1=-5\\y_2=3[/tex]
Substitute:
[tex]m=\frac{3-(-5)}{4-0}[/tex]
Combine terms:
[tex]m=\frac{8}{4}[/tex]
Simplify:
[tex]m=2[/tex]
_
Let's graph these two points. As seen on the graph attached, we can see that [tex]-5[/tex] is the y-intercept. With our slope and y-intercept, we have the information needed to formulate an equation in slope-intercept form:
[tex]y=mx+b[/tex]
Identify your values:
[tex]m=2[/tex]
[tex]b=-5[/tex]
Substitute:
[tex]y=2x-5[/tex]

Round to the nearest tenth.
4.8367
Answer:
Number = 4.8367
Rounded to the nearest tenth means, rounded to the number after the decimal point.
We will have to round down because the hundredth is less than 5
So, we get,
4.8367 becomes, 4.8
Therefore 4.8367 rounded to the nearest tenth = 4.8

The number 4.8367, when rounded to the nearest tenth, becomes 4.8
What is rounding a number to some specific place?Rounding some number to a specific value is making its value simpler (therefore losing accuracy), mostly done for better readability or accessibility.
Rounding to some place keeps it accurate on the left side of that place but rounded or sort of like trimmed from the right in terms of exact digits.
The digit 5 acts as a limit.
if the right sided digit to the digit where we've to round off is < 5, we keep it same and make all right sided values 0, and if the right sided digit is > 5, then we make it increase by 1 and rest of the right sided digits become 0. If the digit on right is 5, and after it there is only zeros or no value, then we round up (increase by 1, as we did in 347500 -> 34800 ) (Well there are many detailed rules of rounding)
Rounding to the nearest tenth means rounding the first place to the right of the decimal point.
The given number is 4.8367
The digit on the right of the decimal point is 8. On the right of that, there is 3, which is < 5, so the first right digit on right of the decimal point, after rounding, will have no change,and rest of the numbers from the right first place of the decimal point will get trimmed off.
Thus, we get:
4.8367 → 4.8 (after rounding to the nearest tenth)
Thus, the number 4.8367, when rounded to the nearest tenth, becomes 4.8

3.1 Subtracting a whole from a fraction
Rewrite the whole as a fraction using 4 as the denominator :
28 28 • 4
28 = —— = ——————
1 4
Equivalent fraction : The fraction thus generated looks different but has the same value as the whole
Common denominator : The equivalent fraction and the other fraction involved in the calculation share the same denominator
Adding fractions that have a common denominator :
3.2 Adding up the two equivalent fractions
Add the two equivalent fractions which now have a common denominator
Combine the numerators together, put the sum or difference over the common denominator then reduce to lowest terms if possible:

Now,to get rid of the denominator, Tiger multiplys both sides of the equation by the denominator.
Here's how:

Now, on the left hand side, the 4 cancels out the denominator, while, on the right hand side, zero times anything is still zero.

Add 112 to both sides of the equation :
