Answer:
x=13
Step-by-step explanation:
4x-(x+7)=2(x+3)
change the sign of (x+7) as it has minus before the bracket and multiply 2 with (x+3)
4x-x-7=2x+6
Now bring all variables to one sides and the non to the other
4x-x-2x=6+7
Simplify
x=13

Your bedroom wall is 221 inches wide. You want to hang two posters, each 28 inches across, with an equal space between each poster and the wall edges. How many inches of space should you leave between the wall edge and each poster?
Answer:
55 inches
Step-by-step explanation:
2 posters x 28 inches each = 56
221 - 56 = 165 inches
3 blank spaces on wall
165 ÷ 3 = 55 inches between posters and on either side
Dan invests £1500 into his bank account.
He receives 3% per year simple interest.
How much will Dan have after 2 years?
Give your answer to the nearest penny where appropriate.
Answer:
£1,725.00
Step-by-step explanation:
To calculate simple interest, we use the formula:
a = p(1 + rt)
a is the answer
p is the principle, or the starting amount of money
r is the rate, or the rate of interest (the percent)
and t is the time, or years.
First, 3% as a decimal is 0.03
So we can plug that in as r.
Then just plug the rest of the numbers in.
a = 1500(1 + 0.03 x 2)
Then just solve the equation to get 1,725.00.
Hope this helps!

Answer:
The volume of the triangular prism in the diagram is:
105.5 [tex]in^{3}[/tex]The surface area of the triangular prism in the diagram is:
10.75 [tex]in^{2}[/tex]Step-by-step explanation:
First, we're gonna calculate the surface area to obtain the volume, then, to calculate the area of a triangle (because the surface o a triangular prism is just a triangle), you can use the formula:
Area of a triangle = (base * height) / 2We have this data from the diagram, where the base of the triangles is 5 inches and, the height is 4.3 inches, replacing this in the formula:
Area of a triangle = ( 5 in * 4.3 in) / 2Area of a triangle = ( 21.5 [tex]in^{2}[/tex]) / 2Area of a triangle = 10.75 [tex]in^{2}[/tex]Now, we can calculate the volume of the triangular prism with the next formula:
Volume of a triangular prism = surface area * depthIn the diagram, we can see the depth is 14 inches, then:
Volume of a triangular prism = 10.75 [tex]in^{2}[/tex] * 14 inVolume of a triangular prism = 105.5 [tex]in^{3}[/tex]How you can see with the calculations perfomed, the surface area is 10.75 [tex]in^{2}[/tex] and the volume of that triangular prism is 105.5 [tex]in^{3}[/tex].

The graphs below have the same shape. What is the equation of the red
graph?
A. g(x) = 1 x^2
B. g(x) = (1 - x)^2
C. g(x) = 7 - x^2
D. g(x) = (7 - x)^2
Answer:
the answer is g(x) = 1 - x²
Since the intercept of g(x) are :
for x intercept , g(x) =0 (1-x)×(1+x) =0
and for y intercept y= 1
hence then its should be g(x) = 1- x²
The equation of red graph that is g(x) = 1 - x²
Given,
f(x) = 4 - x²
g(x)
Now,
Since the intercept of g(x) are :
for x intercept , g(x) =0 (1-x)×(1+x) =0
and for y intercept y= 1
Thus the equation of graph will be :
g(x) = 1- x²
The coefficient of x² is negative which indicates that the graph is concave down in nature .

Step-by-step explanation:
[tex]10t^-5 = 10/t^5[/tex]
The value of 10[tex]t^{-5[/tex] in positive power is 10/ [tex]t^5[/tex].
What are Exponents and power?The base number is the number that is being multiplied by itself an infinite number of times, and the exponent is the number of times that it is being multiplied. The nth power of the given number is an expression that results from multiplying a given number by itself n times.
We have,
Expression: 10[tex]t^{-5[/tex]
We know to make the power positive we have to reciprocate the number.
Now, using exponents we get

x = 97.6
Step-by-step explanation:
cos = adjacent over hypotenuse
[tex]cos(55)=\frac{56}{x}[/tex]
* multiply each side by x *
[tex]cos(55)*x=xcos(55)\\\frac{56}{x} *x=56\\56=xcos(55)[/tex]
* divide each side by cos ( 55 ) *
[tex]\frac{xcos(55)}{cos(55)} =x\\\frac{56}{cos(55)} =97.63302055[/tex]
we're left with x = 97.63302055
Our last step is to round to the nearest tenth of a foot
We get that x = 97.6
