Answer:
the number of hours does sidney skate in all is 9.8 hours
Step-by-step explanation:
The computation of the number of hours does sidney skate in all is as follows:
= Last month + this month
[tex]= 1 \frac{1}{10} + 8 \frac{7}{10}\\\\= \frac{11}{10} + \frac{87}{10}\\\\= \frac{98}{10}[/tex]
= 9.8 hours
Hence, the number of hours does sidney skate in all is 9.8 hours

6 Which expression below has a coefficient of 3?
A. 5x + 9
B. 2x-3
C. 28? + 3x – 6
gx+4
( IS IT A. B. C. or D.?)
option c is the correct cofficient of 3
solve for x using the correct order operations
12- (3 times 2)^2 + 4 times 3 = x
A x = -60
B x = -12
C x= 48
D x = 12
please help i will give brainliest :))
Answer:
B: x = -12
Step-by-step explanation:
12 - (3 × 2)^2 + 4 × 3
Use PEMDAS, meaning solve what's in the parentheses first (P stands for parentheses)
12 - (6)^2 + 4 × 3
We get 6 because 3 × 2 = 6
Next step is solve any exponents (E for exponents)
12 - 36 + 4 × 3
We get 36 because 6 × 6 = 36 (the exponent was 2 meaning multiply the same number, 6, twice: 6 × 6)
Now we move on to multiplication and division (M for multiplication and D for division)
These are interchangable in that either can go first depending on its location in the equation
However, since there is no division in this problem we automatically skip to multiplication
12 - 36 + 12
We answered 12 because 4 × 3 = 12
Our last steps in PEMDAS are addition and subtraction (A for addition and S for subtraction)
These are also interchangable, but both are apparent in this problem
Now it depends on location
Whichever sign (addition or subtraction) is first in accordance from left to right is where we start first)
Subtraction is first
-24 + 12
Now we add -24 + 12
-12

Find the missing length
I WILL GIVE BRAINLIEST
Answer: 30
Step-by-step explanation: Assuming that the side lengths correspond with one another you can set up a ratio to solve
It should look something like this: 15/25 = 18/x
With this equation set up you can solve by cross multiplying. 25(18)=15x
Then start sloving:
25(18)=15x
450=15x
450/15=15x/15 (divide both sides by 15)
30=x
Twice the difference of 1 and a number.

To control his weight, Joel reduced his calorie intake from 2500 calories to 1950 calories each day. What was his percent decrease for calorie intake?
Answer:
22%
Step-by-step explanation:
The change in calories = 1950 - 2500 = -550
percent decrease for calorie intake = (change in calories / initial calorie intake ) x 100
[tex]\frac{-550}{2500}[/tex] X 100 = -22%
Answer:
22%

A saving account earns 4.5 simple interest per year. If 650.00 is deposited and no withdrawals or deposits are made during one year how much interest will be earned after one year
Answer:
29.25 Interest
Step-by-step explanation:
Take the formula: I=PRT
The principal is 650.00, 4.5 is the rate, 1 year is the time, We do not know the interest.
Change the rate, 4.5 to 0.045 to help solve the problem.
Times 650.00, 0.045, and 1 together.
You will get 29.25, Which is the answer!
Booyah! You are done.
Hope this helps!

There are 2 rectangular windows in Ms.
Ridley's dining room. One window is 31 inches
wide and 32 inches tall. The other window is
27 inches wide and 32 inches tall. What is the
difference in the areas of the windows in Ms.
Ridley's dining room?
8 square inches
4 square inches
132 square inches
128 square inches
Answer:
128 square inches
Step-by-step explanation:
Window one's area is 31 times 32 which is 992 in^2
Window two's area is 27 times 32 which is 864 in^2
Subtract 992 from 864 to get the difference

Answer:
3, 10, -2/3
Step-by-step explanation:
I don't speak spanish, so I hope i did this right.
Problem 1
set equal to each other
2x+1=x+4
-4 -4
2x-3=x
-2x -2x
-3=-x
times -1 to get a positive x
3=x
Problem 2
repeat steps
4x-5=3x+5
+5 +5
4x=3x+10
-3x -3x
x=10
Problem 3
repeat steps
x=4x+2
-4x -4x
-3x=2
divide
x=- 2/3
to find the y's, go back and plug in
Prob 1: y=(3+4) =7
Prob 2: y=[3(10)+5] =35
Prob 3: y=(-2/3) =-2/3
Answer:
1.)
y = 2x + 1
y = x + 4
Substitute
2x + 1 = x + 4
Subtract 1 on both sides
2x + 1 - 1 = x + 4 - 1
2x = x + 3
Subtract x on both sides
2x - x = x - x + 3
x = 3
Now that we have x we can use that for finding y
y = x + 4
y = 3 + 4
y = 7
x = 3
y = 4
( 3, 4 )
__________________________________________________________
2.)
y = 4x - 5
y = 3x + 5
Substitute
4x - 5 = 3x + 5
Add 5 on both sides
4x - 5 + 5 = 3x + 5 + 5
4x = 3x + 10
Subtract 3x on both sides
4x - 3x = 3x - 3x + 10
x = 10
Now that we have x, we can use that to find y
y = 3x + 5
y = 3 (10) + 5
y = 30 + 5
y = 35
x = 10
y = 35
( 10, 35)
__________________________________________________________
3.)
y = x
y = 4x + 2
Substitute
x = 4x + 2
Subtract 4x on both sides
x - 4x = 4x - 4x + 2
-3x = 2
Divide -3 on both sides to isolate the variable
-3x/-3 = 2/-3
x = -2/3
Now that we have that we can use it to find y
y = x
y = -2/3
x = -2/3
y = -2/3
( -2/3, -2/3)
Hope this helped!

Answer:
Original price = $49.98
Step-by-step explanation:
Target has it listed for $34.99 which is 70% of the original price.
Let the original price be x.
ATQ,
[tex]70\%\ of\ x=34.99\\\\x=\dfrac{34.99\times 100}{70}\\\\x=\$49.98[/tex]
So, the original price of the Lego set is $49.98.
