Answer:
Question 3: 93 Question 4: -18
Step-by-step explanation:
Use Order of Operations (BEDMAS - Brackets Exponents Division Multiplication Addition and Subtraction).
Question 3:
Start with the numbers inside the brackets.
3^2 (4+6) + 3
= 3^2 (10) + 3
Then, solve the exponents.
= 9 (10) + 3
Multiply 9 and 10.
= 90 + 3
Add the numbers.
= 93
Question 4:
Again, start with the brackets.
3 (4+2) - 6^2
= 3 (6) - 6^2
Then, solve the exponent.
= 3 (6) - 36
Multiply 3 and 6.
= 18 - 36
Subtract the numbers.
= -18 (You can do 36 - 18 which is 18, then add the negative sign)

The anwer pls:Cameron has 2 video game holder stands. Each stand has 2 rows of 20 and 2 rows of 24 games. Find the total number of video games Cameron's stands can hold.
Answers
Answer: 176
Step-by-step explanation:
GIven: In each stand,
It has 2 rows of 20 games.
It has 2 rows of 24 games.
Total number of video games in each stand = 2 x 20 + 2x 24
= 40+48
= 88
Since there are 2 identical stands,
then toral video games in 2 stands = 2 (88)= 176
Hence, the total number of video games Cameron's stands can hold= 176.

Anna earns money by walking dogs on Saturdays. Each Saturday she walks 5 dogs for 30 minutes. She charges one
customer $8 because the dog is very large. Each of the other customers pays $6. Which equation could be used to find out
how much money Anna earns each Saturday?
A)
y = 6 + 8
B)
y = 4 x 6 + 8
09
y = 4 * 6-8
D)
y = 5 x 6 + 8
Answers
Answer:
y = 4 x 6 + 8
Step-by-step explanation:
the 4 is the amount of dogs that arent big
the is 6 is the amount that she gets for walking the normal sized dogs
the 8 dollars is the amount that she gets for walking the big dog
so you would multiply 4x6 which would give you 24
then add the 8 and you will get 32
so that would mean she gets 32$ every saturday

vnfcjvfn dcjxfhhnvn vn
Step-by-step explanation:
Answer:
the value of 7x-y is -14.
Step-by-step explanation:
When x=2 and y=4,
To find the value of 7x - y when x =2, y = 4, this means when ever you see x, put 2 in replacement, y, put 4 respectively.
7x - y = 7(2 - 4)
14 - 28

The terminal side of θ passes through the point (10, 6). What is the exact value of cos θ in simplified form?
Answers
Answer:
[tex]\frac{5\sqrt{34}}{34}[/tex]
Step-by-step explanation:
The formula for cos θ is a/r. A is the first number (10) and b is the second number (6). R is the hypoteneuse which can be found through r = [tex]\sqrt{a^{2} + b^{2} }[/tex].
In the equation you'd write that as r = [tex]\sqrt{10^{2} + 6^{2}[/tex] which can be simplified to [tex]\sqrt{136[/tex].
You end up with [tex]\frac{10}{\sqrt{136} }[/tex] and you simplify this by doing [tex]\frac{10 }{\sqrt{136} } * \frac{\sqrt{136} }{\sqrt{136} }[/tex], ending with the result of [tex]\frac{5\sqrt{34}}{\sqrt{34} }[/tex].

Irene says the equation 9x+15=3x+15 has no solution because 9x is greater then 3x. is he right yes or no and explain why
Answers
Answer:
This equation has one solution, if x = 0
Step-by-step explanation:
Because, you subtract 15 from both sides so: 9x + 15 - 15 = 3x + 15 - 15 which equals: 9x = 3x. if x = 0 this equation is true.
Answer:
X=0
Step-by-step explanation:
If we subtract 15 from both sides, then we can see 9x=3x. If x was 0, then the equation would be 9x0=3x0. Since 0 times anything equals 0, this equation would be true resulting in 0=0.

pleasee help mee
Answers
Answer: 6in, 8in, 10in
6 squared + 8 squared equals to the radical of 100, which equals to 10 because 10 squared is.. 100
The measurements that can be used to build a right-angled triangle are
[tex]6 in, 8 in, 10 in[/tex]
The measurements that can be used to build a right-angled triangle must form a Pythagorean triple. A Pythagorean triple is a set of three numbers [tex]\{x,y,z\}[/tex] that satisfy the Pythagorean relationship
[tex]x^2+y^2=z^2[/tex]
The measurements [tex]\{5 in, 7 in, 12 in\}[/tex] do not form a triple since
[tex]5^2+7^2=74\ne12^2[/tex]
The measurements [tex]\{8 in, 12 in, 14 in\}[/tex] do not form a triple since
[tex]8^2+12^2=208\ne14^2[/tex]
The measurements [tex]\{5 in, 9 in, 11 in\}[/tex] do not form a triple since
[tex]5^2+9^2=106\ne11^2[/tex]
The measurements [tex]\{6 in, 8 in, 10 in\}[/tex] form a triple since
[tex]6^2+8^2=100=10^2[/tex]
So, the last set of measurements [tex]6 in, 8 in, 10 in[/tex] can be used to build a right-angled triangle

A school receive a shipment of four boxes of paper in the school wants to split the paper equally among its three printers how much paper should go into each printer?
Answers
Answer:
[tex]\dfrac{4}{3}[/tex]
Step-by-step explanation:
Number of boxes of paper = 4
Number of printer = 3
We have to find the number of pages in each printer.
Let the number of pages in each box be 1.
Total number of pages in 4 boxes = 4
3 printer will have pages = 4
1 Printer will have pages = [tex]\dfrac{4}{3}[/tex]
Hence, pages each printer will have is equal to [tex]\dfrac{4}{3}[/tex].
