7(x+2)-5(x+3=9(4-x)
Answer:
x = 37/11
Step-by-step explanation:
7(x + 2) - 5(x + 3) = 9(4 - x)
=> 7x + 14 - 5x - 15 = 36 - 9x
=> 2x - 1 = 36 - 9x
=> 11x = 37
=> x = 37/11

Can someone please tell me how to subtract 1 3/8 by 3/4
Please help!
Answer:
2 1/8
Step-by-step explanation:
In order to subtract two fractions with unlike denominators, you have to bring them to THE SAME denominator. You can do that by multiplying both the numerator and denominator of 3/4 by 2 (so it can have a denominator of 8) to get 6/8. Then, simply add 1 3/8 and 6/8 by combining the numerators and keeping the denominators the same. You should get 1 9/8 which is, as a mixed number, 2 1/8

Directions: Solve for x, then find each angle measure
Answer:
Step-by-step explanation:
the sum of the interior angles of a triangle is 180°
so
9x + 3 + 11x - 21 + 5x - 2 = 180
25x = 180 - 3 + 21 + 2
25x = 200
x = 200 : 25
x = 8
----------------
E = 9 * 8 + 3 = 75°
D = 5 * 8 -2 = 38°
F = 11 * 8 - 21 = 67
-------------------------
check
75 + 37 + 67 = 180°
The required simplified value of the x is 8, as of the given condition.
A figure of the triangle is given, from the measures of the angle we have to determine the value of the x.
What is simplification?The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.
Here,
As for the property of a triangle, the sum of the angle is 180,
5x - 2 + 11x -21 + 9x + 3 = 180
25x -20 = 180
25x = 200
x = 8
Thus, the required simplified value of the x is 8.

Answer:
2035
Step-by-step explanation:
2010=100g
2020=70
100-70=30
70-30=40
2030=40
Answer:
Somewhere in 2038
Step-by-step explanation:
In 2010 in there was 100g of a certain radioactive isotope
In 2020 now there’s 70g of a certain radioactive isotope
what changed,?
In 10 years they lost 30g of radioactive isotope
Therefore
Year 2030 there will be 50g
Year 2035 there will be 35g
Year 2040 there will be 20g
But we want to get 25g in how many years
1 year takes 3g
2 year takes 6g
3 year takes 9g
4 year takes 12g
But we need to take away 10g from 35 so it’ll be between somewhere between 2038 maybe half year..

A car moving at a constant speed passed a timing device at t = 0. After 6 seconds, the car has traveled 534 ft. Write a linear function rule to model the distance in feet d the car has traveled any number of seconds t after passing the timing device.
Answer:
d = 89t
Step-by-step explanation:
d = distance --- t = timing device --- x = speed or feet per x
d = tx
linear equation from this (SOLVE) --> 534 = 6x ---> 89 = x
linear equation --> d = 89t
Answer:
[tex]f(x)=89x[/tex]
Step-by-step explanation:
With the given information, you have 2 points.
1. (0, 0)
2. (6, 534)
With 2 points, you can calculate the slope of the linear function.
[tex]m=\frac{y2-y1}{x2-x1} \\m=\frac{534-0}{6-0} \\m=\frac{534}{6} \\m=89[/tex]
Finally, you can write a function:
[tex]f(x)=mx+b[/tex]
No need to calculate the y-intercept as thats already given in point (0, 0).
[tex]f(x)=89x+0\\f(x)=89x[/tex]

if there are 139,799,000 square miles of water on earth what percent is left on earth that is not covered in water
The percentage of earth that is not covered in water is given by the equation A = 29 %
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 total area of earth be = 196,900,000 square miles
And , 71% of Earth’s surface is covered in water
So ,
Percentage of earth's surface covered in water = 71 %
And , area of earth covered by water = 139,799,000 square miles
Substituting the values in the equation , we get
So , the remaining percentage of earth not covered in water A = 100 - 71
On simplifying the equation , we get
Remaining percentage of earth not covered in water A = 29 %
The remaining area of earth = 0.29 x 196,900,000
The remaining area of earth = 57,101,000 miles²
Therefore , the value of A is 29 %
Hence , the percentage is 29 %

the price of a machine is given as GHC 20,000 plus VAT. If the VAT rate is 12%, find the price that a customer must pay for the machine.
Answer:
Step-by-step explanation:
12/100 × 20000
= 2400
Price customer must pay = 20,000+ 2400 = 22400.
If price of a machine is given as GHC 20,000 plus VAT. If the VAT rate is 12%. Then 22400 is the price that a customer must pay for the machine.
What is Percentage?Percentage, a relative value indicating hundredth parts of any quantity.
Given,
The price of a machine is given as GHC 20,000 plus VAT
The VAT rate is 12%,
We need to find how much a customer has to pay for the machine..
12% is changed to decimal number by dividing with 100.
12/100=0.12
Now multiply 20000 with 0.12 to find 12% of 20000
0.12×20000=2400
Now we have to add 2400 with 20000 to get the cost of machine after adding VTA
20000+2400=22400
Hence 22400 is the price that a customer must pay for the machine.
