Step-by-step explanation:
First, let's rewrite the equations.
1/2x + 1/3y =6
x - y = 2
The easiest system to use for substitution is the second one. Let's solve for X.
x - y = 2
add y to both sides!
x = 2 + y
Now that we know x = 2 + y we can use it to substitute in the first equation.
1/2(2 + y) +1/3y = 6
1 + 1/2y +1/3y = 6
5/6y = 5
y = 36/5
write the log equation as an exponential equation. you do not need to solve for x.
Answer:
2x^5log=1/6
Step-by-step explanation:
using the natural log (e), we were able to give the power of 5 to 2x and then take it out from the parantheses

Meg is a veterinarian. She found that 33% of the 21 dogs she saw this week were boxers.Steve is also a veterinarian. He found that 10,or 50% he saw this week were boxers.Does each person need to find the part, the whole, or the percent? Meg needs to find the?
Answer:
a. Meg needs to find the part
b. Steve needs to find the percent.
Step-by-step explanation:
The question is incomplete.
This is the complete question:
Meg is a veterinarian. In a given week, 50% of the 16 dogs she saw were Boxers. Steve is also a veterinarian. In the same week, 7 of the 35 dogs he saw this week were Boxers. Each wants to record the part the whole, and the percent.
a. Does Meg need to find the part, the whole, or the percent.
b. Does Steve need to find the part, the whole, or the percent.
Solution to the problem
a. Does Meg need to find the part, the whole, or the percent.
Meg already knows the whole and the percent.
The whole is the entire number of dogs seen: 16 dogs.
The percent is 50%.
Hence, she needs to find the part: this is how many (what part) of the 16 dogs she saw were boxers.
And she can do with a simple operation:
Part = whole × percent = 16 × 50% = 8. This is 8 dogs of 16 were boxers.
b. Does Steve need to find the part, the whole, or the percent.
He already knows the part (7 of the 35 dogs were boxers) and the whole (35 dogs).
Then he needs to find the percent, which he can do using the next operation:
Percent = (part / whole) × 100 = (7/35)×100 = 20%
f(x) = 3x^2+ 4x^2 – 8x - 2
g(x) = 3x - 5
Find (f - g)(x).
A hockey team plays 42 matches. It wins 21, draws 14 and loses the rest. Express each of these results as a percentage of the total number of games played.
Express the number of each result as a fraction of the total number of games played and multiply with 100.
The percentage of the games won is :21/42 × 100 = 50%The percentage of the draw games is :14/42 × 100 = 100/3 = 33 1/3%The percentage of the games lost is :42-21-14/42 × 100 = 7/42 × 100 = 50/3 = 16 2/3%6y - 5 = 7y - y what does y equal

Answer: y is a false statement
Step-by-step explanation: put all the y terms on one side and all the constants on the other. i'm going to move all the y terms to the right and the constants to the left. on the left we have a -5 leftover and on the right it would be 7y-y-6y. if you add those terms together, you're left with -5=0 which is not possible. y is a false statement
10x+5 is greater than or equal to 2x-3
Answer:
x ≥ - 1
Step-by-step explanation:
10x + 5 ≥ 2x - 3 ( subtract 2x from both sides )
8x + 5 ≥ - 3 ( subtract 5 from both sides )
8x ≥ - 8 ( divide both sides by 8 )
x ≥ - 1

Could a triangle have angle measures of 94°, 106°, and 11° EXPLAIN HOW YOU KNOW.
Answer:
Nope
Step-by-step explanation:
All angles have to measure up to where adding up two of any angles will result in a number greater than or equal to the angle that was not added.
But here if we add up 94° and 11°, we end up with 105°.
Since 105° is lower than the angle not added, which is 106°, this triangle cannot exist.
