A price is increased by 5% and is now £756.
Work out the original price.
Answer:
£720
Step-by-step explanation:
100+5 = 105
105% = 756
divide both sides by 105 to find 1%
1% = 7.2
multiply both sides by 100 to find 100%
100% = 720
756/105 X 100 = 720

Step-by-step explanation:
My computer wont allow it but the 5 and the 7 are exponents
Answer:
[tex]-108x^{5}y^{7}[/tex]
Step-by-step explanation:
Simplify using the laws of exponents (there are more rules than listed, these given rules are just the ones that come into play here);
- when there is a term in parenthesis with an exponent outside, the term's exponent gets multiplied by the exponent outside
- when multiplying two exponents, one can only combine terms with the same base, and one must add the exponents
[tex](3xy^{2})^{3}*(-4x^{3}y)\\\\=(3^{3}*x^{3}*y^{2{^{3}}}) *(-4x^{2}y)\\\\=(27x^{3}y^{6})(-4x^{2}y)\\\\=-108x^{5}y^{7}[/tex]
Right answer gets brainlist
Answer:
153
Step-by-step explanation:
Calculate the area of each side first, then add it all up
Width x height = area of square/rectangle
1/2 x width x height = area of a traingle
x - y = -2
4x - y = 4
[tex] \begin{cases} x - y = - 2 \\ 4x - y = 4 \end{cases}[/tex]
Use the elimination method as it is faster. We have to eliminate the y-term. (You can eliminate the x-term but it takes longer than eliminating y-term.)Simply multiply the negative one in one of the equations.
[tex] \begin{cases} - x + y = 2 \\ 4x - y = 4 \end{cases}[/tex]
We can finally eliminate the y-term by adding both equations.
[tex]( - x + 4x) + (y - y) = 2 + 4 \\ 3x + 0 = 6 \\ 3x = 6 \\ x = \frac{ 6 }{3} \longrightarrow \frac{ \cancel{6}}{ \cancel{3}} = 2 \\ x = 2[/tex]
Substitute the value of x in any given equations. I will substitute in the first equation.[tex]x - y = - 2 \\ 2 - y = - 2 \\ 2 + 2 = y \\ 4 = y[/tex]
Check the answer by substituting the value of x and y in both equations.First Equation
[tex]x - y = - 2 \\ 2 - 4 = - 2 \\ - 2 = - 2 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Second Equation
[tex]4x - y = 4 \\ 4(2) - 4 = 4 \\ 8 - 4 = 4 \\ 4 = 4 \longrightarrow \sf{true} \: \: \green{ \checkmark}[/tex]
Hence, the solution is (2,4).
Answer[tex] \begin{cases} x = 2 \\ y = 4 \end{cases}[/tex]
Coordinate Form

Which of the following functions represents an arithmetic sequence?
1. f(n)=3n^2−4
2.f(n)=3n−4
3.f(n)=3^n−4
4.f(n)=3^n−4^n
Answer:
Option (2)
Step-by-step explanation:
Explicit formula of an arithmetic sequence is always in the linear form.
A(n) = a + (n - 1)d
Here A(n) = nth term of the sequence
a = first term
n = number of term
d = common difference
Formula doesn't have the terms with the exponent.
Therefore, from the given options, expression that represents an arithmetic sequence will be,
f(n) = 3n - 4
Option (2) will be the correct option.
At a pie cook-off, the judges ate 512 of Mary’s pie and 916 of Jerome’s pie.
The pies were the same size.
Choose Yes or No to tell if the statement about the two pies is true.
Answer:
No
Step-by-step explanation:
I think you meant to put 5/12 ad 9/16 but in any case, even if it were 51/2 and 91/6 or anything else, the answer would be no
Solve for the inequality x / 3 < -7
Answer:
[tex]x < - 21[/tex]
Step-by-step explanation:
1. Multiply both sides by 3.
[tex]x < - 7 \times 3[/tex]
2. Simplify 3 × 7 to 21.
[tex]x < - 21[/tex]
therefor, the answer is x < -21

Pls help its my last question?!?!
Answer:
x = -11
m<B = -43
m<C = -22
Step-by-step explanation:
To solve for x, solve (3x-10) + (2x) + 65 to get 5x+55. Simplify to 5x = -55. This can simplify further to x = -11. Insert -11 as x into the angles.
I hope this is correct and helps!

Answer:
1. slope m = 1; y-intercept b = 3
2. slope m = ; y-intercept b = 4
3. slope m = 3; y-intercept b = 1
4. slope m = [tex]\frac{1}{2}[/tex]; y-intercept b = 1
5. the slope demonstrates the cost of toppings PER topping and how the price increases per topping. the y-intercept is the starting cost WITHOUT toppings (when toppings = 0) and the slope increases the price starting with the y-intercept because it is the initial cost. the graph is attached

What is 4/9 x 5/7 x 1/2
Answer:
0.16
Step-by-step explanation:
4*5*1=20
9*7*2=126
20/126=10/63
Answer:
10/63
Step-by-step explanation:
First, let's solve 4/9 * 5/7. Multiply the numerator first- 4*5=20. The denominator is 9*7=63. So, this equals 20/63. Now we need to find 20/63 * 1/2. We can cancel out the 2 on the denominator and divide 20 on the numerator by 2. So, you get 10/63 * 1/1, which is 10/63.
