Answer:
-8
Step-by-step explanation:
3 + -4 - 7
3 - 4 - 7
-1 - 7
-8
Answer: -8
Step-by-step explanation:
3+(-4)-7
Whenever you have a +(- something), it ALWAYS becomes a -
So 3+(-4)= 3-4
Now we have:
3-4-7
PEMDAS states that you must do the subtraction from left to right. So you start with the 3-4.
3-4-7
-1-7
-8
Whenever you have a negative number minus a number , the result will always be negative.
Hence, thats why the answer is -8

Step-by-step explanation:
Insert a digit in each place "..." to make numbers that are divisible by 6
if it is possible:
4...9
the question isn't possible to answer because 9 is not divisible by 6
Answer:
It is not possible to make 4_9 divisible by 6
Step-by-step explanation:
A number that is divisible by 6 will be divisible by 2 and by 3. An integer is divisible by 2 if its units digit is even. An integer is divisible by 3 if the sum of its digits is divisible by 3.
__
The given number has a units digit of 9, which is not even. The number cannot be made divisible by 2 for any inserted digit.
It is not possible to make 4_9 divisible by 6.
how do i turn a fraction into its simplest form?
Answer:
You divide both the numerator and the denominator by the same number until they can't be reduced any further.
Answer:
Make sure to divide the upper number and the lower number (in position) to a number which can't be futher divided. It will be of numbers which are really small numbers. like 4/2 will be divided by 2 to get the simplified answer of 1/2

Answer:
30%
Step-by-step explanation:
To express percentage as a fraction, the denominator must be 100.
Given ,
[tex]\frac{18/60}{60/60}\\= \frac{0.3}{1} \\= 0.3 * 100\\= 30%[/tex]
Answer:
1) Percent of skateboards that are longboards is 18÷60 or 30%
2) Number needed for equivalent ratio is 30 longboards
Step-by-step explanation:
1) Percentage= part divided by whole
18÷60 = 0.3
0.3 = 30%
2) Create a proportion, let x = # longboards needed for a equivalent ratio
(18÷60)=(x÷100)
x=30
John works as a part time waiter in a restaurant. He gets a monthly salary of ₹4,410.Calculate John’s daily, weekly and annual salary.(Take 1 month= 30 days)
1 month is aprox. 30 days, so
To find john's daily salary:
For a month, the salary is 4,410 rupees, so for a day how much?
days salary
30 4,410 (This is how I learnt to solve these kind of problems)
1 ?
Then you crisscross the equation which becomes
4,410/30=147 rupees
To find weekly salary:
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 7 days (1 week) how much?
You multiply the salary for one day and the number of days: 147×7=1,029 rupees
To find salary for a year (annual):
we now know the salary for one day so we can say: For a day, the salary is 147 rupees, so for 365 days (1 year) how much?
You multiply the salary for one day and the number of days: 147×365=53,655 rupees
Hope it helps!

Step-by-step explanation:
This program simplifies our complex monetary system by familiarizing users with common combinations of coins and bills that are equivalent in value. Starting with five pennies equal one nickel, the program works up to equivalents for a twenty dollar bill.
Answer:
$1.05
Step-by-step explanation:
1 dime = 10 cents so 7 dimes = 70 cents
1 quarter = 25 cents
Therefore 10 cents + 7 dimes + 1 quarter = 10 + 70 + 25 = 105 cents = $1.05

equation: -7x+6= x squared-7x
Answer:
x = √6 or - √6
Step-by-step explanation:
equation: -7x + 6 = x² - 7x
switch sides:
x² - 7x = -7x + 6
Add 7x to both sides,
x² - 7x + 7x = -7x + 7x + 6
x² = 6
For x² = f(a) the solution are x = √f(a), -√f(a)
x = √6 , x = - √6
Answer:
-7x + 6 = x² - 7x
-7x + 7x +6 - x² = 0
0 + 6 - x² = 0
-x² + 6 = 0
-x² = (-6)
x² = 6
x = ±√6
x =√6 or x = -√6

Someone help w pre-algebra, smth about proportional data
Answer:
The answer is no because for 1 hour he gets 20 dollars and for 2 hours he gets 30$ (which is less for working 2 hours). So, if you multiply 2 hours with 20 dollars, you should get 40, not 30. So therefore, it is not proportional. And same for 3 hours: multiply 3 with 20 to get 60, not 50.

Answer:
one paperback = 0.6 pounds
one textbook = 3.6 pounds
Explanation:
Let the mass of one paperback be 'p' and one textbook be 't'.
Equation one:
sum of mass = total mass in box
20p + 9t = 44.4Equation two:
20p + 5p + 9t + 1t = 5125p + 10t = 51make 't' subject
10t = 51 - 25pt = 5.1 - 2.5pInsert this into equation one:
20p + 9(5.1 - 2.5p) = 44.4
20p + 45.9 - 22.5p = 44.4
20p - 22.5p = 44.4 - 45.9
-2.5p = -1.5
p = 0.6
The weight of 1 paperback is 0.6 pounds.
The weight of 1 textbook:
t = 5.1 - 2.5p
t = 5.1 - 2.5(0.6)
t = 3.6
The weight of 1 textbook is 3.6 pounds.

The surface areas of the solids shown above are equal, but their lateral
surface areas are not.
A. True
B. False
Answer:
Flase
Step-by-step explanation:
Solid a has a surface area of 170 sq ft.
Solid b has a surface area of 126 sq ft.
Just knowing this information we already know that the statement is false
Answer:
False
Step-by-step explanation:
1. Find the surface area
Shape 1 Shape 2
(4 x 5)2 + (5x5)4 = 140 (6 x 3)2 + (3 x 5)2 + (6 x 5)2 = 126
2. Exclude the bases

In a music competition, a participant has to score a total of at least 40 points in the first four rounds combined to move on to the fifth and final round. Glenn scored 4 points in the first round. He then went on to score additional points in the second, third, and fourth rounds. In each of those rounds, his score was identical. Which inequality best shows the number of points, p, that Glenn scored in each of the second, third, and fourth rounds if he earned a place in the finals?
a 4 + 3p ≤ 40
b 4 + 3p ≥ 40
c 4p + 3 ≥ 40
d 4p + 3 ≤ 40
Answer:
b 4 + 3p ≥ 40
Step-by-step explanation:
he needs more than 40 points, so we need to pick and answer with a greater than or equal to sign that faces the side with Glenn's points. This leaves b or c for our answers. Glenn played 3 different rounds in which he scored a value represented by the variable p. Additionally, he scored a value of 4 points is given. Therefore, because he scored p in 3 different rounds, p is multiplied by 3 to make 3p. So, 4+3p≥ 40 (answer b) is correct
Answer:
b 4 + 3p ≥ 40
