Solve the simultaneous equations 4x+y=10 X-5y=13
Answer: 4x + y = 10 is -y+10/4 X-5y=13 is x=5y+13
Step-by-step explanation:
The value of x and y in the equations given are -2 and 3 respectively.
What are equations?An equation is a mathematical statement that shows that two mathematical expressions are equal.
Given are two equations, 4x+y = 10 and x-5y = 13, we need to solve the equations,
4x+y = 10.......(i)
x-5y = 13
x = 13+5y......(ii)
Substituting eq(ii) in eq(i)
4(13+5y)+y = 10
52+20y+y = 10
21y = 10-52
21y = -42
y = -2
Put y = -2 in equation (ii),
x = 13+5(-2)
x = 13-10
x = 3
Hence, The value of x and y in the equations given are -2 and 3 respectively

which number is written in scientific notation?
Answer:
Scientific notation is a way of writing very large or very small numbers. A number is written in scientific notation when a number between 1 and 10 is multiplied by a power of 10. For example, 650,000,000 can be written in scientific notation as 6.5 ✕ 10^8.
Step-by-step explanation:
At 12 noon, the
temperature was
3°F. Then the
temperature fell
steadily and reached
-1°F at 2:00 PM.
Noon to 2:00 pm is 2 hours
3 degrees to -1 degree is a total of 4 degrees.
The temperature changed 4 degrees in 2 hours.
4/2 = 2
The temperature dropped 2 degrees per hour.
3(x - 7) + 4 = 28 - 2x
Answer:
3x-21+4=28-2x...... Multiply 3 with (x-7)
3x+2x=28+21-4......Take - 2x from right side to left side which makes it +2x and - 21+4 from left side to right side which makes it +21-4
5x=45.....Add and subtract as required
x=45/5....Taking 5 from left side to right side and dividing it

Answer:
7.5% error
Step-by-step explanation:
Percent Error = ( | measured - real | / real ) x 100%
|430 - 400| / 400 = |-30| / 400
( 30 / 400 ) x 100%

Bri wants to buy as many flip flops as she can at the store. Each flip flop costs $4 and she has $50 with her. Write an inequality to show the maximum number of flip flops Bri can buy.
Answer:
she can buy 12½flip flops
Step-by-step explanation:
it's actually easy : just do 50÷4 but then u will get something like 12.5 so if you are confused , you can divide by the closest number to 50 and the number which is a multiple of 4
so,
48÷4 = 12 and with the remaining 2 $ she can buy a half flip flop more if she wants because 4/2
Therefore , the total number of flip flops she can buy = 12½ flip flops

A square with an area of 250sq.m is inscribed in a circle. Find the diameter of the circle
Answer:
22.36 m

Answer: 9^-16
Step-by-step explanation:
If an exponents have the same base and are being multiplied together, all you do is just add the exponents and make the base stay the same
9[tex]9^{-53} * 9^{37} = 9^{-16}[/tex]
Negative exponents can be rewritten as positive exponents if you put them in the denominator.
[tex]x^{-a}=\frac{1}{x^a}[/tex]
Using this rule, we can rewrite the equation.
[tex]9^{-53}*9^{37}=\frac{1}{9^{53}}*9^{37}[/tex]
[tex]\frac{9^{37}}{9^{53}}[/tex]
Then, we can use exponent division rules.
[tex]\frac{x^a}{x^b}=x^{a-b}[/tex]
[tex]\frac{9^{37}}{9^{53}}=9^{37-53}[/tex]
[tex]9^{-16}[/tex] or [tex]\frac{1}{9^{16}}[/tex]
Hope this helps.
