[tex]7x - 3y = 80[/tex]Fill in the missing number. % of 64 = 48
Answer:
75%
Step-by-step explanation:
Step 1: Build the equation.
[tex]\frac{x}{100}(64) = 48[/tex]Step 2: Simplify.
[tex]\frac{64}{100}x = 48[/tex] [tex]\frac{16}{25}x = 48[/tex]Step 3: Multiply both sides by 25/16.
[tex]\frac{16}{25}x * \frac{25}{16} = 48 * \frac{25}{16}[/tex] [tex]x = 3 * \frac{25}{1}[/tex] [tex]x = 75[/tex]Therefore, the missing number is 75 to complete the equation 75% of 64 = 48.

~ 7equation a. 100x-10x+270=5670
Answer:
60
Step-by-step explanation:
90x + 270= 5670
90x=5670-270
x=5400÷90
x=60
Answer:
x = 60
Step-by-step explanation:
1) 100x - 10x + 270 = 5670
2) 100(60) - 10(60) + 270 = 5670
3) 6000 - 600 + 270 = 5670
4) 5400 + 270 = 5670
5) 5670 = 5670
All I really did was input random numbers for the value of "x", then add 270 at the end of an equation. If that method works for me, it should work for everyone, including you.

1. Please help me with this problem I will give you the brain thing and extra points
Which equation in standard form has a graph that passes through the point (0, -5) and has a slope of 3/4?
A)3x + 4y = -20
B)3x - 4y = 20
C)4x + 3y = 20
D)4x - 3y = -20
Answer:
B) 3x - 4y = 20
Step-by-step explanation:
We can eliminate C and D since 4(0) + 3(-5) = -15 (not 20) and 4(0) - 3(-5) = 15 (not -20)
Now we will determine the slopes for A and B to see which one is correct:
A) 3x + 4y = -20 -> 4y = -20 - 3x -> y = -5 - 3/4x -> y=-3/4x - 5 (not right)
B) 3x - 4y = 20 -> -4y = 20 - 3x -> y = -5 + 3/4x -> y = 3/4x - 5 (right)
Therefore, B is correct since the slope is 3/4 and passes through (0,-5)
Please help this question..
Step-by-step explanation:
2).
Given that 1/(7+5√2)
We know that
The Rationalising factor of a+√b is a-√b
The denominator = 7+5√2
The Rationalising factor of 7+5√2 is 7-5√2
On Rationalising the denominator then
=> [1/(7+5√2)]×[ (7-5√2)/(7-5√2)]
=> [1×(7-5√2)]/(7+5√2)(7-5√2)]
=> (7-5√2)/[(7+5√2)(7-5√2)]
=> (7-5√2)/[7²-(5√2)²]
Since , (a+b)(a-b) = a²-b²
Where , a = 7 and b = 5√2
=> (7-5√2)/(49-50)
=> (7-5√2)/(-1)
=> -7+5√2
=> 5√2-7
3).
Given that (x-2)³
This is in the form of (a-b)³
Where, a = x and b = 2
We know that
(a-b)³ = a³-3a²b+3ab²-b³
=> (x-2)³ = x³-3(x²)(2)+3(x)(2)²-2³
=> (x-2)³ = x³-6x²+12x-8
The coefficient of x² is -6
Becky bought seven more packages of dried apples than packages of dried apricots. If she bought fifteen packages of these two fruits all together, how many apples and apricots did she buy each?
Answer:
Apples = 11, Apricots = 4
Step-by-step explanation:
Apple= 7 + Apricots
15 = Apple+ Apricot
15= 7 + Apricots + Apricots
15 = 7 +2Apricots
8 = 2 Apricots
4= 1 Apricot
Apple = 7 + 4 = 11
Hikers walk 3 miles east and then 2 miles north and take a water break. They continue
hiking 4 miles east and a final 2 miles south to their destination. What single
transformation took place from their starting position to their final destination? Use
mathematical language and create a graphic to explain your answer. Be sure to use a
straight edge and grid paper for your graphic to represent this problem.
The single transformation that took place from their starting position to their final destination is (x, y) ⇒ (x + 7, y)
What is transformation?Transformation is the movement of a point from its initial location to a new location. Types of transformation are rotation, reflection, translation and dilation.
Translation is the movement of a point either up, down, left or right in the coordinate plane.
Hikers walk 3 miles east and then 2 miles north and take a water break. Hence:
(x, y) ⇒ (x + 3, y + 2)
They continue hiking 4 miles east and a final 2 miles south to their destination:
(x, y) ⇒ (x + 3 + 4, y + 2 - 2) ⇒ (x + 7, y)
The single transformation that took place from their starting position to their final destination is (x, y) ⇒ (x + 7, y)

Step-by-step explanation:
To practice for a competition, Maggie swam 940 meters in the pool each day for 2 weeks. How many kilometers did Maggie swim in those 2 weeks? 1 m = 0.001 km
Based on the number of days that Maggie swam and the distance swam everyday, Maggie swam 13.16km
Maggie swam 940 meters each day. She did this for two weeks. The total distance she swam is:
= 940 x 2 x 7 days a week
= 13,160 meters
A meter is 0.001km so 13,160 meters in kilometers would be:
= Number of meters x Conversion factor
= 13,160 x 0.001
= 13.16 km
In conclusion, Maggie swam 13.16 km.

Find the equation of the line that is perpendicular to the line
6x – 4y = 3 and passes through the point (6,-1).
(a) Find the slope of the given line 6x – 4y = 3.
(b) What is the slope of a line that is perpendicular to the above line?
(c) Now, find the equation of the perpendicular line that passes through (6,-1).
Answer:
a). y = 3/2x - 3/4 b).-2/3 c).y = -2/3x + 3
Step-by-step explanation:
a). 6x – 4y = 3
-4y = -6x + 3
y = 3/2x - 3/4
- The slope is 3/2.
b). The slope of a perpendicular line would be the opposite: -2/3
c). y = -2/3x + b
-1 = -2/3(6) + b
-1 = -4 + b
3 = b
y = -2/3x + 3

Step-by-step explanation:
I guess we are only talking about quadratic functions/equations here.
the world is not unified regarding what is the standard form of a quadratic equation.
but let's assume your teacher means
standard form
f(x) = y = ax² + bx + c
vertex form
f(x) = y = a(x - h)² + k
so, we are using the provided x, y coordinates to get a, b and c.
3.75 = a×0.125² + b×0.125 + c
3 3/4 = a×(1/8)² + b×(1/8) + c
15/4 = a/64 + b/8 + c
15×16/64 = a/64 + 8b/64 + 64c/64
=> 240 = a + 8b + 64c
4 = a×0.25² + b×0.25 + c
4 = a×(1/4)² + b×(1/4) + c
4 = a/16 + b/4 + c
4×16/16 = a/16 + 4b/16 + 16c/16
=> 64 = a + 4b + 16c
3 = a×0.5² + b×0.5 + c
3 = a×(1/2)² + b×(1/2) + c
3 = a/4 + b/2 + c
3×4/4 = a/4 + 2b/4 + 4c/4
=> 12 = a + 2b + 4c
we have now from the third equation
a = 12 - 2b - 4c
we put this into the second equation
64 = (12 - 2b - 4c) + 4b + 16c = 12 + 2b + 12c
32 = 6 + b + 6c
26 = b + 6c
b = 26 - 6c
and therefore
a = 12 - 2(26 - 6c) - 4c = 12 - 52 + 6c - 4c = 2c - 40
this a and b we use now in the first equation
240 = (2c - 40) + 8(26 - 6c) + 64c =
= 2c - 40 + 208 - 48c + 64c = 18c + 168
72 = 18c
c = 4
b = 26 - 6×4 = 26 - 24 = 2
a = 12 - 2×2 - 4×4 = 12 - 4 - 16 = -8
so, the standard form is
f(x) = y = -8x² + 2x + 4
the vertex form
we get this by transforming the standard form.
e.g. by competing the square :
y - 4 = -8x² + 2x = -8(x² - x×1/4)
y - 4 -8×(1/8)² = -8(x² -x×1/4 + (1/8)²)
y - 4 - 8/64 = -8(x - 1/8)²
y - 32/8 - 1/8 = -8(x - 1/8)²
y - 33/8 = -8(x - 1/8)²
y = -8(x - 1/8)² + 33/8

Answer:
∠ PQR = 150°
Step-by-step explanation:
∠ PQR = ∠ PQS + ∠ SQR , substitute values
12x - 6 = 16 + 9x + 17
12x - 6 = 9x + 33 ( subtract 9x from both sides )
3x - 6 = 33 ( add 6 to both sides )
3x = 39 ( divide both sides by 3 )
x = 13
Then
∠ PQR = 12x - 6 = 12(13) - 6 = 156 - 6 = 150°
Answer:
m<PQR = 150°
Step-by-step explanation:
<PQR = (12x-6)°
<SQR = (9x+17)°
<PQS = 16°
find m<PQR.
since <SQR + <PQS = <PQR,
then (9x+17)° + 16° = (12x-6)°
combine like terms;
9x + 17 + 16
9x + 33 = 12x - 6
subtract 33 from both sides;
9x = 12x - 39
subtract 12x from both sides;
-3x = -39
divide by -3;
x = 13, then input x into the equation for m<PQR;
m<PQR = (12x-6)°,
(12(13)x - 6)°
(156 - 6)°
Answer: 150°

Express the product of (x + 1) and (3/2x+5/3)as a trinomial in simplest
form.
The product of the given expression (x + 1)(3/2x+5/3) is 3/2x² + 29x/6.
What are mathematical operations?A mathematical "operation" is the process of calculating a value using operands and a math operator.The supplied numbers or operands must follow specific guidelines associated with the math operator's symbol.Arithmetic operators perform the operations of addition, subtraction, multiplication, division, exponentiation, and modulus.So, (x + 1)(3/2x+5/3):
Now, solve as follows:
(x + 1)(3/2x+5/3)x(3/2x+5/3) + 1(3/2x+5/3)3/2x² + 5/3x + 3/2x + 5/33/2x² + 2(5)x + 3(3)x + 2(5)x/63/2x² + 10x + 9x + 10x/63/2x² + 29x/6Therefore, the product of the given expression is 3/2x² + 29x/6.
