Answer:

Step-by-step explanation:

We are given the expression:

$4x+ \frac{1}{3} y^2$

We know that x=2 and y=3. Therefore, we can substitute 2 for x and 3 for y.

$4(2)+ \frac{1}{3} (3)^2$

Solve according to PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Subtraction.

First, evaluate the exponent.

3^2 = 3*3 = 9

$4(2)+ \frac{1}{3} (9)$

Next, multiply 4 and 2.

$8+ \frac{1}{3} (9)$

Multiply 1/3 and 9, or divide 9 by 3.

$8+3$

Add 8 and 3

$11$

Helppppp!!!! I don’t understand it

oksian1 [2.3K]

Okay so for 2x-y > 3
Subtract -2 from each side
-y>-2x+3
Divide by -1
And when you divid you gotta switch signs
So it’s y<2x-3

3x-5y less than and equal to 25
Subtract 3
-5y is less than and equal to -3x+25
Then divide by -5
Flip since we divide
Y more than and equal to 3/5x-5
We always flip signs when we divid or multiple
I hope this help
Sorry if I’m wrong

Because hit 7 more home runs than Beverly. Because hit 22 home runs. How many home runs did Beverly hit?

nekit [7.7K]

The answer choice isn't even up there. The answer is 15. Since Because hit 22 home runs; you would just subtract to find the number of Beverly's home runs since it says "7 more home runs than Beverly".

22 - 7= 15.

Hopefully this helps

There is a competition in the cinema to win free tickets. You must guess the ages of the four employees. Here are the clues: - W

Answer:

Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old.

Step-by-step explanation:

Let $k$ be Kirk's age.

Let $b$ be Brian's age.

Let $m$ be Matt's age.

Let $m_{1}$ be the boss/manager's age.

From the information given, we can set up 4 equations:

$k+b+m+m_{1}=106$

$k=2(m_{1}-10)$

$b=2m_{1}-12$

$m=\frac{1}{2}m_{1}+6$

Rewrite the first equation, substituting $k$ , $b$ , and $m$ in terms of $m_{1}$ to get:

$2(m_{1}-10)+(2m_{1}-12)+(\frac{1}{2}m_{1}+6)+m_{1}=106$

Open up the parentheses using the distributive property (which is $a(b-c)=ab-ac$ ) and combine like terms to get:

$5.5m_{1}-26=106$

Add 26 to both sides to reach:

$5.5m_{1}=132$

Thus, $m_{1}=24$ . Substitute $24$ for $m_{1}$ in the second, third, and fourth original equations to find that $k=28$ , $b=36$ , and $m=18$ . Therefore, Kirk is 28 years old, Brian is 36 years old, Matt is 18 years old, and the manager is 24 years old. To check, you can add up all of the ages to get 106.
