17/24 kilograms of crab was sold by Mang ernie on Saturday.
EquationEquation is an expression used to how the relationship between two or more numbers and variables.
Let x represent the amount of crab that was sold by Mang ernie. Hence, from the question:
x + 1/6 = 7/8
subtracting 1/6 from both sides of the equation to make x the subject of the equation:
x + 1/6 = 7/8 - 1/6
x = 17/24

A pump releases water at a rate of 10 gallons every 45 days.
What is the unit rate in gallons per week?
Enter your answer as a mixed number in simplest form in the box.
gal/week
Answer:
6 miles
Step-by-step explanation:
6 times 4 = 24
Answer:
10 mph, 1 5/9
Step-by-step explanation:
Set up a ratio:
4/24 = x/60
Cross multiply and solve
4 * 60 = 24x
240 = 24x
10 = x, 10 mph
10 gallons every 45 days is ever 6 3/7 weeks
10 divided by 6 3/7
10 divided by 45/7=
10 times 7/45 = 70/45, = 14/9 = 1 5/9

How much of Earth's water is salt water? 97 percent 71 percent 60 percent 100 percent.
Answer:
96.5 or 97
Step-by-step explanation:
To break the numbers down, 96.5% of all the Earth's water is contained within the oceans as salt water, while the remaining 3.5% is freshwater lakes and frozen water locked up in glaciers and the polar ice caps. Of that fresh water, almost all of it takes the form of ice: 69% of it, to be exact.

Answer:
(-2,-2)
Step-by-step explanation:
Step: Substitute 3x+4 for y in y=−x−4:
y=−x−4
3x+4=−x−4
3x+4+x=−x−4+x (Add x to both sides)
4x+4=−4
4x+4+−4=−4+−4 (Add -4 to both sides)
4x=−8
4x/4=−8/4(Divide both sides by 4)
x=−2
Step: Substitute −2 for x in y=3x+4:
y=3x+4
y=(3)(−2)+4
y=−2(Simplify both sides of the equation)
What is an equation of the line that passes through the points (6, 5) and (6, -7)?
Answer:
If a line is parallel to another line they’ll have the same slope. We can figure out the slope by taking the given equation of a line and changing it to slope-intercept formula.
x + 3y = 15
3y = -x + 15
y = -1/3 x + 5
Now we know the slope of our line is -1/3. We can use this and the given point to calculate our y-intercept, commonly known as b in the slope-intercept formula.
-5 = -1/3 (-6) + b
-5 = 2 + b
-7 = b
Now that we know our slope, m, and our y-intercept, b, we can write the equation of the line.
y = mx + b
y = -1/3 x - 7

5) 180 - (125+30)
X= 25
6) 6x = 120
X = 120/6
X= 20
8) 89 - (29 + 12)
X= 48
9) (3x+30) = 162
X = (162-30)/3

Find the distance between (11, 7), (16, 6)
Answer:
The answer is √26
Step-by-step explanation:
Given;x₁ = 11; x₂ = 16y₁ = 7; y₂ = 6Let the point be A and B i.e.,
A = (11, 7)
B = (16, 6)
Now, The distance between A and B
AB = √(x₂ – x₁)² + (y₂ – y₁)²
AB = √(16 – 11)² + (6 – 7)²
AB = √(5)² + (-1)²
AB = √25 + 1
AB = √26
Thus, The distance between A and B is √26

Triangle mid-segment ???
Answer:
22
Step-by-step explanation:
The midsegment is always half as long as the base, so
2(6 + 4x) = 5x + 24
12 + 8x = 5x + 24
3x = 12
x = 4
Replace the 4 in for x,
6 + 4(4) = 22

–10 times the first equation and 3 times the second equation
10 times the first equation and 3 times the second equation
–3 times the first equation and 5 times the second equation
3 times the first equation and 5 times the second equation
Answer:
Its the second one x=5
Step-by-step explanation:
I took the test.
Answer:
-10 times the first equation and 3 times the second equation
Step-by-step explanation:
Multiply the first equation by 10 and the second equation by -3:
1. 1/5 x + 3/4 y = 9
x-10 ⇒ -2x - 15/2 y = -90
2. 2/3 x - 5/6 y = 8
x3 ⇒ 2x - 5/2 y = 24
Add the equations together:
-2x - 15/2 y = -90
+ 2x - 5/2 y = 24
-------------------------
0x - 10y = -66

[tex]math[/tex]
Step-by-step explanation:
Answer:
Firstly, we know 3^3 ÷ 3^-4 =2187. So, we got to check the value for each expression given below.
3x 3^6 = 2187
3^7 ÷ 3^0 = 2187
3^-3 ÷ 3^4 = 1/2187 (odd one out)
3^3 x 3^4 = 2187
Answer is 3^-3 ÷ 3^4

Plz help me. I need your help
Step-by-step explanation:
1.
a mother is a she, not a he ...
anyway, we need to make 2/3 and 3/4 comparable.
for this we need to bring both fractions to a common denominator, which is usually the smallest common multiple of the denominators.
yes, 12 is the smallest number that can be divided by 3 and by 4 without remainder.
to transform a fraction too another denominator, we need to multiply it by a fraction a/a, which has the value 1, of course (so we don't change the value of the original fraction), but changes the denominator to the desired number.
what do I multiply with 4 to get 12 ? 3.
so, I multiply 3/4 by 3/3 = 9/12.
what do I multiply with 3 to get 12 ? 4.
so, I multiply 2/3 by 4/4 = 8/12.
now we can compare and calculate :
out of the total of 9/12kg 8/12kg were used.
that means
1/12kg of carrots are left.

this is a strange question, as watermelons, bananas and melons are very differently sized. so, for example 1/2 watermelon and 1/2 banana are very different quantities.
so, what does e.g. 1 fruit mean ?
or if we understand the fractions as shares of the overall smoothie, then we have too much. 4/6 (watermelon) + 2/6 (melon) = 6/6 = 1 (whole smoothie).
so, what to do with the banana ?
this question does not make any sense at all.
but if it is just to add fractions, we can do that :
4/6 + 1/2 + 2/6
as mentioned above, 4/6 + 2/6 = 6/6 = 1
1 + 1/2 = 2/2 + 1/2 = 3/2 = 1.5 or 1 1/2
so there is 1 1/2 fruit in the smoothie (whatever that means).
3.
1 1/2 + 2 1/2 = 2/2 + 1/2 + 4/2 + 1/2 = 8/2 = 4

im in 10th grade geometry and need help
Answer:
x = √55
Step-by-step explanation:
using Pythagoras Theorem:
x² + 3² = 8²
x² = 64 - 9
x² = 55
x = √55 ..........this is your answer in radical form.
x = 7.416
Answer:
x = √55 = 7.4162
Step-by-step explanation:
The Pythagorean Theorem states that a^2 + b^2 = c^2
so 3^2 + x^2 = 8^2
x^2 = 64 - 9 = 55
x = √55 = 7.4162
