j + 17/4 = 7
HELP QUICK
Answer:
J = 11/4
Step-by-step explanation:
J + 17/4 = 7
7 as a fraction
7 x 4 = 28
28/4
J + 17/4 = 28/4
J + (17/4 - 17/4) = (28/4 - 17/4)
J = 11/4
Answer:
j = 11/4
Step-by-step explanation:
For quick answer just in your head multiply 4 by 7, which is 28. Then subtract 17 since that’s the given, which you will get 11. So j = 11/4. Hope this somewhat makes sense.
To solve for the value of j, we need to isolate j on one side of the equation.
First, we can simplify the left side of the equation by multiplying both sides by 4 to get rid of the fraction:
j + 17/4 = 74(j + 17/4) = 4(7)
4j + 17 = 28
Next, we can isolate j by subtracting 17 from both sides:
4j + 17 - 17 = 28 - 174
j = 11Finally, we can solve for j by dividing both sides by 4:
j = 11/4
Therefore, the value of j that satisfies the equation is j = 11/4.
we can check whether j = 11/4 is the correct solution by substituting it into the original equation and seeing if it is true.
j + 17/4 = 7
When we substitute j = 11/4, we get:
(11/4) + 17/4 = 7
Simplifying the left side of the equation, we get:
28/4 = 7
Both sides of the equation simplify to 7, which means that the solution j = 11/4 is correct.
To further verify, we can also add 11/4 and 17/4 to get:
11/4 + 17/4 = 28/4 = 7
Since we obtained the same value for both sides of the equation, we can conclude that the solution j = 11/4 is correct.

Answer:
w≥77
Step-by-step explanation:
Multiply 11 by 7.
Answer:
[tex]w\geq 77[/tex]
Step-by-step explanation:
How would you get w by itself so that it makes it simplify?
Either you Multiply/Divide and Subtract/Add.
In your case you have [tex]\frac{w}{7} \geq 11[/tex]
To get w by itself you multiply 7 to both side leaving w.
[tex]7*\frac{w}{7}\geq 11*7[/tex]
Seven cancel out on the left side leaving w.
11 * 7 = 77.
[tex]w\geq 77[/tex]

Which of the following combinations of side lengths will form a triangle with vertices X, Y, and Z?
(A.) XY = 18 mm , YZ = 20 mm , XZ = 39 mm
(B. ) XY = 17 mm , YZ = 20 mm , XZ = 36 mm
(C.) XY = 16 mm , YZ = 20 mm , XZ = 37 mm
(D.) XY = 17 mm , YZ = 19 mm , XZ = 37 mm
Answer:
(A.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 18 mm, YZ = 20 mm, and XZ = 39 mm. This is because the sum of the lengths of any two sides of a triangle must be greater than the length of the third side according to the triangle inequality theorem. In this case, XY + YZ = 18 mm + 20 mm = 38 mm, which is greater than XZ = 39 mm, satisfying the triangle inequality theorem.
(B.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 20 mm, and XZ = 36 mm. This is because XY + YZ = 17 mm + 20 mm = 37 mm, which is greater than XZ = 36 mm, satisfying the triangle inequality theorem.
(C.) A triangle will not be formed with vertices X, Y, and Z with side lengths XY = 16 mm, YZ = 20 mm, and XZ = 37 mm. This is because XY + YZ = 16 mm + 20 mm = 36 mm, which is not greater than XZ = 37 mm, violating the triangle inequality theorem.
(D.) A triangle will be formed with vertices X, Y, and Z with side lengths XY = 17 mm, YZ = 19 mm, and XZ = 37 mm. This is because XY + YZ = 17 mm + 19 mm = 36 mm, which is greater than XZ = 37 mm, satisfying the triangle inequality theorem.

The tires on Jasmine's bicycle have a circumference of about 70.4 inches. Find the approximate diameter of each tire. Use 3.14 for π. Round to the nearest hundredth if necessary.
Answer:
The approximate diameter of each tire on Jasmine's bicycle can be calculated by dividing the circumference by π (pi). Using the given circumference of 70.4 inches and rounding π to 3.14, the calculation would be as follows:Diameter = Circumference / π
Diameter = 70.4 / 3.14
Diameter ≈ 22.45 inches (rounded to the nearest hundredth)So, the approximate diameter of each tire on Jasmine's bicycle is 22.45 inches.
The approximate diameter of each tire is 22.42 inches.
What is the diameter of the tires on Jasmine's bicycle?A circle is simply a closed 2-dimensional curved shape with no corners or edges.
The circumference of a circle is expressed mathematically as;
C = 2πr
or
C = πd
Where r is radius, d is diameter, and π is constant pi ( π = 3.14 )
Rearrange this formula to solve for the diameter:
C = πd
d = C/π
Substituting the given value of the circumference, we have:
d = 70.4/3.14
d = 22.42 in
Therefore, the diameter is 22.42 in.

Given that 1+5b+9c=1 , 4a+2b+3c=2, 7a+8b+6c=9
what is 741a + 825b + 639c?
Answer:
741a + 825b + 639c = 1375/9.
Step-by-step explanation:
To solve this problem, we need to first find the values of a, b, and c that satisfy the given system of equations. We can use any method of solving systems of linear equations, such as substitution or elimination. Here, we will use the elimination method:
Multiplying the first equation by -4 and adding it to the second equation, we get:
-20b - 36c = -2
Multiplying the first equation by -7 and adding it to the third equation, we get:
29b + 45c = 8
Multiplying the second equation by -29/20 and adding it to the third equation, we get:
-21b - 39c = 67/10
Now we have three equations in two variables. We can solve for b and c using any method, such as elimination or substitution. Here, we will use substitution:
From the second equation, we can solve for a in terms of b and c:
a = (2 - 2b - 3c)/4
Substituting this expression for a into the third equation, we get:
741/4 - 825/2 b + 639/6 c = 9
Simplifying and solving for b, we get:
b = (3/5) - (3/5) c
If this helps, please mark my answer as brainliest
Substituting this expression for b into the second equation, we get:
(27/5) c = (2/5)
Solving for c, we get:
c = -(2/27)
Substituting this value of c into the expression for b, we get:
b = (3/5) - (3/5) (-2/27) = (11/27)
Substituting the values of a, b, and c into the expression 741a + 825b + 639c, we get:
741a + 825b + 639c = 741[(2 - 2b - 3c)/4] + 825b + 639c
= 741[(2 - 2(11/27) - 3(-2/27))/4] + 825(11/27) + 639(-2/27)
= 741(5/27) + 275/3 - 426/9
= 1375/9
Therefore, 741a + 825b + 639c = 1375/9.

Owen has 50% more cash than Sandra, and Sandra has 20% more cash than Amada. How much more cash than Amada does Owen have, if Amada has $4.35?
Answer: $3.48
Step-by-step explanation:
Amada has $4.35. Since Sandra has 20% more cash than her, Sandra has $5.22. Owen has 50% more cash than Sandra, so he has $7.83. The difference between $7.83 and $4.35 is $3.48.

Answer:
The solution is ([4], [19]).
Step-by-step explanation:
To solve the system of equations using the substitution method, we can follow these steps:Step 1: Start with the given equations:
y = 4x + 3 (Equation 1)
y = 7 + 3x (Equation 2)Step 2: Choose one of the equations and solve for one of the variables in terms of the other variable. Let's choose Equation 1 and solve for y in terms of x:
y = 4x + 3Step 3: Substitute the expression for y from Equation 1 into Equation 2 and solve for x:
4x + 3 = 7 + 3x (Substituting y = 4x + 3 from Equation 1)
4x - 3x = 7 - 3
x = 4Step 4: Substitute the value of x found in Step 3 back into either Equation 1 or Equation 2 to solve for y. Let's use Equation 1:
y = 4(4) + 3 (Substituting x = 4)
y = 19So the solution to the system of equations is x = 4 and y = 19. Therefore, the solution is ([4], [19]).

In one month, Jason earns $32.50 less than twice the amount Kevin earns. Jason earns $212.50. Write and solve an algebraic equation to show how to find the amount that Kevin earns.
Answer:
Step-by-step explanation:
2K - 32.50 = 212.50
2K = 245
Therefore, Kevin earns 245/2 = $122.50
We can double check this by reversing the solution:
122.50 x 2 = 245
245 - 32.50 = 212.50
Therefore, we can be certain that our answer is correct!
