Literal equations 5y-72=7+5x

Answers

Answer 1

Step 1. Add 72 to both sides

5y = 7 + 5x + 72

Step 2. Simplify 7 + 5x + 72 to 5x + 79

5y = 5x + 79

Step 3. Divide both sides by 5

y = 5x + 79/5

Which of the following rational numbers is equal to 3 point 4 with bar over 4? 31 over 9, 32 over 9, 33 over 9, 34 over 9

Answers

ANSWER


[tex]3.\bar4 =\frac{31}{9}[/tex]


EXPLANATION.

Let [tex]y=3.\bar4---(1)[/tex]


This is a recurring decimal. So we need to multiply by 10 to form a new equation that will cater for the recurring but when subtracted.


Multiply (1) by 10 to obtain,


[tex]10y=34.\bar4---(2)[/tex]


Equation (2) -equation (1) gives;


[tex]9y=31[/tex]


[tex]\Rightarrow y=\frac{31}{9}[/tex]


Hence the correct answer is A.




What is the value of f(x) = 3x - 5 when x = 6

Answers

Plug in 6 for x in the equation:

f(6) = 3(6) - 5

Remember to follow PEMDAS. First, multiply

f(6) = 3(6) - 5

f(6) = 18 - 5

Finally, subtract

f(6) = 18 - 5

f(6) = 13

f(6) = 13 is your answer

Solve the equation. Check your solution, if possible
[tex]4(3q - 2) = 16q[/tex]

Answers

Hey there!!  

Given equation :

... 4 ( 3q - 2 ) = 16q

... 12q - 8 = 16q

Subtract by 12q on both sides

... -8 = 4q

Divide by 4 on both sides

... -8 / 4 = q

... q = -2

Given equation :

4 ( 3q - 2 ) = 16q

Substitute the value of -2 in place of q

... 4 ( -6 -2 ) = 16 × -2

... 4 ( -8 ) = -32

... -32 = -32

∴ Hence proved

What is −13+2z=−56 Thanks

Answers

Final answer:

To solve the equation −13+2z=−56, we isolate z by first adding 13 to both sides, giving 2z=−43, and then dividing both sides by 2, resulting in z=−21.5.

Explanation:

The student is asking for the solution to the linear equation −13 + 2z = −56. To solve for z, we need to perform two steps. First, add 13 to both sides of the equation to isolate the term with z on one side. This gives us 2z = −43. Next, we divide both sides by 2 to solve for z, which results in z = −21.5.

If y = 7x, what happens to x when y is increased by 5 times its original value?
A) x decreases 5 times its original value

B) x increases to 11/5 its original value

C) x also increases 5 times its original value

D) x decrease to 4/5 of its original value

Answers

B) Because to find the value of x and y you have to divide x by 7 to make it x and the multiply 7 by y because you divided by the opposite side, which is x.

One number is one-fifth of another number. The two numbers total 18. Find the numbers

Answers

Answer:

One number is 17 and the other is 85.

Step-by-step explanation:

Let the numbers be m and n.  Let m = (1/5)n.  Note that m+n = 18.

Substituting (1/5)n for m in the 2nd equation, we get (1/5)n + (5/5)n = 18.  Multiplying all three terms by 5 to remove fractions, we get n + 5 = 90, so that n = 85.  m is (1/5) of 85, or m = 17.

Final answer:

The two numbers in question are 15 and 3. To find them, establish a variable for the larger number, set up an equation based on the given ratio and sum, solve for the variable, and divide by five to get the smaller number.

Explanation:

The student wishes to find two numbers where one number is one-fifth of the other and their sum is 18. Let's denote the larger number as x and the smaller number as one-fifth of x, or x/5. The equation representing their sum is x + (x/5) = 18. To solve for x, we first find a common denominator, which is 5, and rewrite the equation as 5x/5 + x/5 = 18. Combining like terms gives us 6x/5 = 18. Multiplying both sides by 5/6, we get x = (18 × 5) / 6. Simplifying this gives x = 15. We then calculate x/5 to find the smaller number, yielding 3. Therefore, the larger number is 15 and the smaller number is 3.

The legs of a right triangle measure 5 inches and 7 inches. If theta is the angle between the 7 inch leg and the hypotenuse, sin theta = ___

Answers

Answer:

sin (θ) = 0,58

Step-by-step explanation:

The formula for sin (θ) is:

sin (θ) = (opposite side)/hypotenuse

The opposite side to the θ angle is the one that measures 5 inches, but we don’t know the measure of the hypotenuse. The Pythagoras theorem gives us the following formula:

side 1²+ side 2²= hypotenuse²

Then,

5²+7²=74

√74= 8,60 inches; this is the measure for the hypotenuse.

Replacing this value in the formula for sine:

sin (θ) = 5/8,60  = 0,58

Reflectional symmetry is the quality a design has if it maintains _____ when it is reflected across an axis or line of symmetry. A. some characteristics B. all characteristics C. no characteristics

Answers

The correct answer would be B, all characteristics. Reflectional Symmetry is when an object is divided into halve in which to completely identical pieces are left.

(B) All characteristics.

Reflection symmetry:In mathematics, symmetry with regard to a reflection is known as reflection symmetry, line symmetry, mirror symmetry, or mirror-image symmetry. In other words, a figure with reflectional symmetry does not alter when it is reflected.There is a symmetry line or axis in 2D and a symmetry plane in 3D. A mirror-symmetric object or figure is one that is identical to its changed counterpart. In conclusion, the shape is divided in two by a line of symmetry, and both parts should be the same.

Therefore, the correct option to fill the blank is (B) All characteristics.

find x if a =13 and C = 47 need help

So you're using the Pythagorean theorem which is a^2 + b^2 = c^2... so if you dont have b you can manipulate the equation. That equation is c^2 - a^2= b^2, so you square 47 which is 2209 and then square 13 which is 169... you do 2209-169 and that equals 2040, then you do the square root of that which is 45.166359 that can be simplified to 45 or two decimal points 45.167.
