Answer:
x = 15, y = 5
Step-by-step explanation:
total score of A = 6x
total score of B = 25*8 = 200
total score of C = 20y
(6x+200)/(x+25)=7.25
6x+200 = 7.25x+181.25
18.75 = 1.25x
x = 15
and
(6x+200+20y)/(x+25+20) = (6x+200+20y)/(x+45) = 6.5
plug in x
(290+20y)/60 = 6.5
290 + 20y = 390
20y = 100
y = 5

Answer:
-0.58
Step-by-step explanation:
The number gets less as you move to the bottom. Each dash represents 0.01. The dot is 3 lines below -0.55, so you would do -0.55 - 0.03, and the answer is -0.58.
I hope this helps and please mark me as brainliest!
Answer:
-0,56
Step-by-step explanation:
As you go up, the numbers tend to get larger. -0.5 is larger than - 0.6
So considering where the dot is on the number line, you have to subtract - 0.02 for every horizontal line you cross.
Another way of putting this is you must add 0.02.
For me, it is easier to add 0.02 because the amount is getting bigger. Why 0.02? it is because there are 5 horizontal notches between -0.6 and - 0.5. Each notch must be -.1/5 = -0.02
First notch: -0.6 + 0.02 = -0.58
Answer: Second notch: -0.58 + 0.02 = -0,56

Solve f(x)=2, if f(x)=1/2x-3
Answer:
10
Step-by-step explanation:
Solve f(x)=2, if f(x)=1/2x-3
Both equations are set to equal f(x) so the solution would be the two equations set to equal each other
2 = 1/2x - 3
==> add 3 to both sides
5 = 1/2x
==> multiply both sides by 2
10 = x
Answer:
x = 10
given:
f(x) = 2
======
[tex]\sf \rightarrow \dfrac{1}{2} x- 3= 2[/tex]
change side
[tex]\sf \rightarrow \dfrac{1}{2} x= 2+3[/tex]
simplify the following
[tex]\sf \rightarrow \dfrac{1}{2} x= 5[/tex]
change side
[tex]\sf \rightarrow x= 5*2[/tex]
final outcome
[tex]\sf \rightarrow x= 10[/tex]
Choose the best estimate for the length of a paperback book. A. 4 in. B. 8 in. C. 14 in. D. 18 in.

WILL CHOOSE BRAINLIEST! The height of a baseball, h (in feet), as a function of time, t (in seconds), is given by the equation h(t)=-16t²+32t+3. find the average velocity (in ft/sec) of the baseball from t=0 to t=1.
Answer:
Given the equation y = -16t^2 + 96t + 3, we know a = -16, b = 96, c = 3.
Let's solve for h in this problem.
h = -b/2a
h = -(96) / 2(-16)
h = -96 / -32
h = 3 seconds
Now let's add t=3 to our equation:
y = -16t^2 + 96t + 3
y = -16*(3)^2 + 96*(3)+ 3
y = -144 + 288 + 3
We now know that the vertex is (3,147), which means that the ball's maximum height is 147 feet.
Answer:
Step-by-step explanation:
Find the height at h(0) and h(1)
h(0) = 3 ft
h(1) = -16 + 32 + 3 = 19 ft
It takes 1 second to go from 3 feet to 19 feet
(19-3) ft / 1 sec = 16 ft/sec

A skateboard was originally priced at $53.00. It is on sale for 15% off. What is the sale price of the skateboard?
Answer:
$45.05
Step-by-step explanation:
To find 10% divide the original number by 10. This is $5.30
To find 5% divide 10% by 2. This is $2.65
Add the two together to get 15%. This is $7.95
Take away the value of 15% from the original number.
$53.00 - $7.95 = $45.05

Let's start by breaking down the problem.
This is how it should look. ↓
[tex]60[/tex] ÷ [tex]20[/tex] ⇒ [tex]+ 3[/tex] ⇒ [tex]x * 5^2[/tex]
What does that x mean? x is just a substituted value for the first 2 equations.
Now, we can solve.
[tex]60[/tex] ÷ [tex]20[/tex] [tex]= 3[/tex]
Add 3
[tex]3 + 3 = 6[/tex]
Now, multiply 6 times 5 squared. What does 5 squared mean? 5 squared is just 5 times itself once. You most likely want to solve 5 squared before multiplying.
[tex]5^2~or~5 * 5 = 25[/tex]
And now for the last step, multiply 25 times 6
[tex]25 * 6 = 150[/tex]
With that information, the problem is solved! Your answer is 150

Michael decided to take all his leftover change each month and place it into a savings account. This account earns 2% simple interest each year. The only thing Michael is putting in this account is his leftover change, which is a small amount. Should Michael keep his account since he is putting very small amounts in and earns very little interest?
A. Yes, his monthly deposits and interest will accumulate, which means the balance will grow over time.
B. No, the monthly bank fees are taking away all his deposits which leaves the account at zero.
