Answers

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.

Solve the simultaneous equations 4x+y=10 X-5y=13

Answers

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

Simplify the expression

Answers

Answer:

9/4

Step-by-step explanation:

5×|-2-7(3)|-2×17

5×|-2-21|-34

5×|-23|-34

5×23-34

115-34=81

22+sq rt(7×28) 28=4×7 sq rt= 2×2×7×7

22+2×7=22+14=36

81÷9/36÷9=9/4

So the answer is a, now let me tell you why if you need proof

Starting from the top
So take the seven and multiply it to the 3 to get 21 and then subtract the negative two to the negative twenty one so you should have 5 | -23| -2*17 simply the |-23| so it says it’s absolute value which is 23 so you have 5*23 - 2*17, now just go ahead and multiply the 5 and the 23 to get 115 and the 2 to the 17 to get 34, now you should have 115-34, that’s obviously 81
Now for the bottom
22 + √7*28, now you just multiply the 7 to the 28 and you get 196 and the square root of that would be 14 so now you should have 81/22+14 so far, now just add the 22 and 14 to get 36 and simplify the fraction to get 9/4 and that’s A
(if you keep going, you get 2.25)

Answers

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
