Answer:
On Monday, Marco practiced the piano for 7/10 hour. On Tuesday he practiced for 11/6 hour. To find out how many hours he practiced in total for these two days, we need to add these two amounts together.
We can add these two amounts together by converting them to a common denominator, in this case 24:
7/10 hour = (7/10) * (24/6) = 724/60 = 72/5 = 14/5 hour
11/6 hour = (11/6) * (24/6) = 114/6 = 112/3 = 22/3 hour
So the total number of hours he practiced for these two days is (14/5) + (22/3) = (14+44)/(5*3) = 58/15 hour
He is supposed to practice 5/4 hours each day. To find out how many hours he is still supposed to practice, we have to subtract the total number of hours he practiced from the total number of hours he is supposed to practice per day:
5/4 hour - 58/15 hour = (53)/(43) - (58/15) = 15/12 - 58/15 = (180-58) / (12*15) = 122/180 hour or 0.67 hour
So Marco is supposed to practice 0.67 hour more to meet his daily practice goal.
However I was not able to read what you wrote please check from here. Thanks.

Answers
Answer:
see below
Step-by-step explanation:
3% * 400 = 3/100 * 400 = 3*4 =12
30% of 11.5 = 30/100 * 11.5 = 3.45
2% of 3350 = 2/100 * 3315 = 67
x = 535/600 =0.891, so 89.1%
x = 70/700 = 0.1 so 10%

what is the value of x?
Answers
Answer:
55
Step-by-step explanation:
A straight line measures at 180 degrees
They gave you 125 and x
Because it's on the same line, we can make the equation
125 + x = 180
Subtracting 125 from both sides gets X alone
x = 180-125
x = 55
Wallace's bike lock is a five-digit code. He tells his friends that the code is $3$ prime numbers that are each $10$ apart, written in increasing order. Hearing this, Izzy laughs because now she knows Wallace's code. What is his code?
Answers
The number of digits is an illustration of combination, and there are 40,000 possible codes that start with a prime number that Genevieve could create
How to determine the number of digits?
The given parameters are:
Length = 5
First digit = Prime number (2, 3, 5, and 7)
This means that the first digit can be any of the 4 prime numbers, while the other four digits can be any of the 10 digits 0 - 9
So, the number of codes is
Code = 4 * 10 * 10 * 10 * 10
Evaluate
Codes = 40,000
Hence, there are 40,000 possible codes that start with a prime number that Genevieve could create
3x +5= 2x - 15............ X=?
Answers
Answer:
[tex] \sf \: x = - 20[/tex]
Step-by-step explanation:
Given equation,
→ 3x + 5 = 2x - 15
Now the value of x will be,
→ 3x + 5 = 2x - 15
→ 3x + 5 - 2x = -15
→ 3x - 2x = -15 - 5
→ x = -(15 + 5)
→ [ x = -20 ]
Hence, the value of x is -20.

Adam plans to choose a video game from a section of the store where everything is 75% off. He writes the expression d - 0.75 d to find the sale price of the game if the original price is d dollars. Rena correctly writes another expression, 0.25 d, that will also find the sale price of the game if the original price is d dollars. Drag each description to explain each part of both expressions.
Answers
Answer:
The expression d - 0.75d finds the sale price of the game if the original price is d dollars by subtracting 75% of the original price from the original price.

In both expressions, d represents the original price of the game. The first expression subtracts 75% of the original price, represented by 0.75d, from the original price to find the sale price. The second expression multiplies the original price by 25%, represented by 0.25, to find the sale price.

convert -11 2/3 into and improper fraction and do the same things for -4 1/5.
so it will become. -35/3 x (-21/5).
TWO NEGATIVE EQUAL A POSITIVE.
35/3 x 21/5 - cancel out the greatest common factor 5
7/3 x 21 - cancel put the great common factor 3
7x7
= 49
How I solved it-
-11 2/3 x (-4 1/5)
I started with turning the mixed numbers into improper fractions, Which the new equation would be, -35/3 x -21/5
Then multiplied them and got 735/15 and then just divide 735 by 15 and you will get 49. Hope this helps!!

Answers
Step-by-step explanation:
I will only do number 1 to help you through this, any questions about the rest just ask!
1. 11 + (20 - 13)
Always start with the parentheses, so first, you will subtract 20 - 13 which will give you 7, with the 7 you will add it to the 11 because that's a leftover number, so you would have to add 11 + 7 which would equal 18.
I usually remember this:
Please Excuse My Dear Aunt Sally,
It stands for
P =Parentheses
E= Exponents
M =Multiplication
D = Division
A = Addition
S = Subtraction
------
Always go in order, that's why I said "Always start with the parentheses" because it's in the first place.
-Hope this helps, good luck !
It stands for,
B-Brackets,
O-Orders (powers/indices or roots),
D-Division,
M-Multiplication,
A-Addition,
S-Subtraction.
This is the order.
But the order depends on which operation comes first. If the division part comes before multiplication, then we first divide before multiplying. If the multiplication comes in before division, then we multiply before dividing. This is same for addition and subtraction too.Here are some examples for multiplication and division.
1) 2 x 8 ÷ 4
=16 ÷ 4
= 4
2) 4 ÷ 2 x 8
= 2 x 8
= 16
Any how you should do multiplication and division before addition and subtraction according to BODMAS.
I will make 6th sum in your paper.
6) ( 2 + 3) x ( 11 - 5 )
= 5 x 6
=30
Study this example,Try to solve
[18 - 2(5 + 1)] ÷ 3 + 7
We begin with solving the innermost bracket first. Starting with 5 + 1 = 6. Thus, [18 - 2(6)] ÷ 3 + 7
Next, we work with the order, thereby multiplying 2 (6) or 2 × 6 = 12. Thus, [18 - 12] ÷ 3 + 7
There is one bracket left, [18 - 12] = 6. So, 6 ÷ 3 + 7
After B and O comes D, hence, 6 ÷ 3 = 2. So, 2 + 7

First, we have to find the area of the rectange which is 221ft² because the formula for finding the area of a rectangle is length x width. Now since we know that each square ft is equal to $11, we have to multiply 11 x 221 which gives us our answer 2431. Now we just add the dollar sign in front and it become $2431!
