67+38 (mod5)
pls can someone help me with this question
Answer:
67 + 38(mod5)
= 67 + 38 =105÷5 (mod5)
= 21 reminder 0 ( mod 5)
Since while handling modes or finites the reminder is always considered therefore;

-2^2(-5x+10)=100
Answer:
[tex]x=7[/tex]
Step-by-step explanation:
Hi there!
[tex]-2^2(-5x+10)=100[/tex]
Solve -2^2:
[tex]-4(-5x+10)=100[/tex]
Divide both sides by -4:
[tex]\displaystyle \frac{ -4(-5x+10)}{-4}=\frac{100}{-4} \\\\-5x+10=-25[/tex]
Subtract 10 from both sides:
[tex]-5x+10-10=-25-10\\-5x=-35[/tex]
Divide both sides by -5:
[tex]\displaystyle \frac{-5x}{-5} = \frac{-35}{-5} \\\\x=7[/tex]
Therefore, x = 7.

The Garcia family has two cars. Last week, the first car consumed 30 gallons of gas and the second consumed 25 gallons of gas. The two cars drove a combined total of 1,250 miles, and the sum of their fuel efficiencies was 45 miles per gallon. What was the fuel efficiency of each of the cars last week?
Answer:
25 and 20 milies/gallons
Step-by-step explanation:
Let the fuell efficientcy of the first and the second car be f and s in gallons/miles.
Then the distance traveled by car 1 is 30 f and the car 2 is 25 s.
Since we also know that 1250 is the total distance traveled then
30 f + 25 s = 1250 (1)
Moreover we know that the efficiency is 45 miles/gallon. Hence
f + s = 45
Multiply by 30 we have
30 f + 30 s = 1350 (2)
Subtract the (1) equation from (2) we have
5s = 100
s = 20
f + 20 =45
f = 25
So the efficiency of the first car is 25 miles/gallons while the second one is 20 miles/gallons.

Find the measure of unknown angle
Answer:
The angle in the upper right quadrilateral corner = 68 degrees because vertical angles are equal.
Angle Y = 68 (opposite quadrilateral angles are equal).
All quadrilateral angles add to 360 so:
68 + 68 + x + z = 360 = 292
angle X + Z = 292
Therefore angle x = angle z = 146
Step-by-step explanation:
Answer:
Step-by-step explanation:
angle Z = 68 degree (being alternate angles)
angle X = 68 degree (opposite angle of a parallelogram is equal)
y + z = 180 degree (sum of adjecent angles of a parallelogram is 180 degree)
y + 68 = 180
y = 180 - 68
y = 112 degree

Solve the following system by using substitute
x - 4y = 28
7y - 6x = - 15
Answer:
y = -9
x = -8
Step-by-step explanation:
x = 28 + 4y
7y - 6(28 + 4y) = -15
7y - 168 - 24y = - 15 ---> *distribute the -6, not positive 6*
-17y = 153
y = -9
x = 28 + 4(-9)
x = -8

Step-by-step explanation:
[tex]$x$: $x = \frac{x}{6} + \frac{x}{12} + \frac{x}{7} + 5 + \frac{x}{2} + 4$[/tex]
The solution is x = 84
The value of the equation is A = 84
What is an Equation?
Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given data ,
Let the equation be represented as A
Now , the value of A is
x = ( x/6 ) + ( x/12 ) + ( x/7 ) + 5 + ( x/2 ) + 4 be equation (1)
On simplifying the equation , we get
x = [ ( x/6 ) + ( x/12 ) + ( x/7 ) + ( x/2 ) ] + 9
Now , on further simplification , we get
x = [ ( x/7 ) + ( x/2 ) ] + [ ( 2x + x ) / 12 ] + 9
x = ( 3x/12 ) + [ ( 2x + 7x ) / 14 ] + 9
x = ( 3x/12 ) + ( 9x/14 ) + 9
On simplifying the equation , we get
x = ( x/4 ) + ( 9x/14 ) + 9
x = [ ( 14x + 36x ) / 56 ] + 9
x = ( 50x / 56 ) + 9
Subtracting ( 50x/56 ) on both sides of the equation , we get
9 = x - ( 50x/56 )
9 = ( 56x - 50x ) / 56
6x/56 = 9
Multiply by 56 on both sides of the equation , we get
6x = 504
Divide by 6 on both sides of the equation , we get
x = 504/6
x = 84
Therefore , the value of x is 84
Hence , the equation is A = 84

The screen size of a tablet is determined by the length of the diagonal of the rectangular screen. The 9.7-inch iPad
Air comes in a 4:3 format, which means that the ratio of the length to width of the rectangular screen is 4:3. What is
the area of the iPad's screen?
Using area of a rectangle, it is found that the area of the iPad's screen is of 45.2 square inches.
---------------------
The area of a rectangle of length l and width w is given by:
[tex]A = lw[/tex]
---------------------
The diagonal of a rectangle is the hypotenuse of a right triangle, in which the sides are the length and the width.
---------------------
The first step before finding the area is finding the length and the width.The ratio of length to width is 4:3, thus, [tex]w = x, l = \frac{4x}{3}[/tex]The diagonal, which is the hypotenuse of a right triangle in which w and l are the sides, is 9.7, and thus, applying the Pythagorean Theorem:[tex]x^2 + (\frac{4x}{3})^2 = (9.7)^2[/tex]
[tex]x^2 + \frac{16x^2}{9} = 94.09[/tex]
Multiplying everything by 9:
[tex]9x^2 + 16x^2 = 846.81[/tex]
[tex]25x^2 = 846.81[/tex]
[tex]x^2 = \frac{846.81}{25}[/tex]
[tex]x = \sqrt{\frac{846.81}{25}}[/tex]
[tex]x = 5.82[/tex]
---------------------
The width is of [tex]w = 5.82[/tex]The length is of [tex]l = \frac{4}{3}(5.82) = 7.76[/tex]Thus, the area is:[tex]A = lw = 7.76(5.82) = 45.2[/tex]
The area of the iPad's screen is of 45.2 square inches.

Two complex numbers are given, where m, n, p, and q are real numbers.
m+ni
p+qi
For what relationship among m, n, p, and q, will be the product of these two complex numbers have only an imaginary part?
This is Algebra 2.
Answer choices:
np mq
mp-np=0
mp+nq=-1
Answer:
[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]
Or:
[tex]pm = qn \text{ and } pn + qm \neq 0[/tex]
Step-by-step explanation:
We are given two complex numbers:
[tex]\displaystyle m + ni \text{ and } p + qi[/tex]
Where m, n, p, and q are real numbers.
And we want to determine the relationship among m, n, p, and q such that the product of the two complex numbers will only have an imaginary part.
Find the product:
[tex]\displaystyle \begin{aligned} (m+ni)(p+qi) &= p(m+ni) + qi(m+ni) \\ &= (pm + pni) + (qmi + qni^2) \\ &= (pm + pni) + (qmi - qn) \\ &= (pm - qn) + i(pn + qm) \end{aligned}[/tex]
Therefore, for the product to have only an imaginary part, the real part must be zero and the imaginary part must not be zero. That is:
[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]
In conclusion, the relationship between m, n, p, and q is:
[tex]\displaystyle pm - qn = 0\text{ and } pn + qm \neq 0[/tex]
Or:
[tex]pm = qn \text{ and } pn + qm \neq 0[/tex]
(Note: I couldn't understand the provided answer choices, but the above answer is indeed correct (and the second equation can be ignored).)
