Answer:
7 x (y+1/3)
because you take the sum in a parentheses to follow PEDMAS and then multiply the sum by 7
An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
The algebraic expression of 7 times the sum of y and 1/3 is
7/3 (3y + 1).
What is an expression?An expression is a way of writing a statement with more than two variables or numbers with operations such as addition, subtraction, multiplication, and division.
Example: 2 + 3x + 4y = 7 is an expression.
We have,
7 times the sum of y and 1/3
This can be written as,
= 7 (y + 1/3)
=7 (3y + 1) / 3
= 7/3 (3y + 1)
Thus,
The algebraic expression of 7 times the sum of y and 1/3 is

15 men can dig a trench og 90m in 3 hours. how long will it take 16 men to dig a trench of 48m long?
Answer:
1.5 hours
Step-by-step explanation:
Answer:
1.5 hours
Step-by-step explanation:
15 men can dig a trench 90 feet deep in 3 hours. So, first, we have to divide 90 by 3 to find the depth that 15 men can dig in 1 hour.
90/3 = 30
Next, we need to divide 30 by 15 to find how deep 1 man can dig in 1 hour.
30/15=2.
Now, since there are 16 men in this second project, we need to multiply 16 by 2 to find how much 16 men can dig in 1 hour.
16x2 = 32.
Finally, we have to add 16 to get 48.
Since we added the depth for 1 hour plus the depth for half an hour to get the total depth, we can say that 16 men can dig 48m in 1.5 hours.

Answer:
Because blue has the least amount of marbles in there
Step-by-step explanation: Because Blue has 2 blue marbles which are smaller than any one of the rest of the marbles. Ur welcome
Mark as brainlyest?
The probability of getting not blue marble is [tex]\frac{7}{8}[/tex].
What is probability?
Probability is a measure of happening or non-happening of the outcomes of a random experiment.
Probability formulaP(E) = number of favorable outcomes/ total number of outcomes
According to the given question.
Total number of red marbles = 5
Total number of yellow marbles = 4
Total number of green marbles = 5
Total number of blue marbles = 2
⇒ Total number of marbles = 5 + 4 + 5 + 2 = 16
So, total number of outcomes = 16
Now, probability of getting blue marble = [tex]\frac{2}{16} = \frac{1}{8}[/tex]
Therefore, the probability of getting not blue marble = [tex]1 -\frac{1}{8} =\frac{7}{8}[/tex]
Hence, the probability of getting not blue marble is [tex]\frac{7}{8}[/tex].

When adding integers with the same sign, add the absolute values of the integers.
True or False?
Answer:
False. This only goes with integers that are both positive.
Step-by-step explanation:
For example, 7+6 is the same as |7|+|6|, which is, again, the same as 7+6.
However, when you add integers that are both negative, you're subtracting, and you'll always end up with a negative difference. Absolute values are always positive, which is why this doesn't work.
(-7)+(-6)
= -7-6
= -13
|-7|+|-6|
= 7+6
= 13

Find the discount.
Original price: $0.75
Discount: ??
Sale price: $0.15
Answer:
80%
Step-by-step explanation:
0.75 ⇒ 100%
0.15 ⇒ x%
0.75x = 100·(0.15)
0.75x = 15
x = 15/(0.75)
x = 1500/75
x = 20%
100% - (discount) = x%
100% - (discount) = 20%
discount = 100%-20%
discount = 80%
Answer:

During the months of August and September the total rainfall I August was 0.6 inch more than the amount f rainfall in September, how much rain fell in each month?
Answer:
August = 3.4
September = 2.8
Step-by-step explanation:
Given
[tex]Total = 6.2\ in[/tex]
Represent August with A and September with S.
So,
[tex]A =S + 0.6[/tex]
Required
Amount of rainfall in each month.
This is calculated using:
[tex]Total = August + September[/tex]
[tex]6.2= A + S[/tex]
Recall that: A = S + 0.6. Substitute
[tex]6.2= S + 0.6 + S[/tex]
[tex]6.2= 2S + 0.6[/tex]
Collect Like Terms
[tex]2S = 6.2 - 0.6[/tex]
[tex]2S =5.6[/tex]
Solve for S
[tex]S = 5.6/2[/tex]
[tex]S = 2.8[/tex]
Substitute 2.8 for S in [tex]A =S + 0.6[/tex]
[tex]A = 2.8 + 0.6[/tex]

Answer:
BCD = 90˚
ABD = 16˚
CBE = 74˚
ADE = 74˚
AEB = 148˚
DEA = 32˚
Step-by-step explanation:
BCD: I suppose that’s a rectangle, and all rectangles have four right (90˚) angles.
ABD: alternate interior angles are congruent, so ABD is congruent to BDC (16˚).
CBE: Complementary angles add up to 90˚, so just subtract ABD (16˚) from 90˚ to equal 74˚.
ADE: Same this as CBE for same reason.
AEB: You need to find DEC first for this. To find DEC, add BDC and ACD together to get 32˚, then subtract that from 180˚ to find the answer (148˚). This is because all triangles have a 3 interior angle measure sum of 180˚. (And vertical angles are congruent).
DEA: Subtract AEB from 180˚ because they’re supplementary angles.
Hope this helps :)

Answer: A. domain: all real numbers
range: all real numbers greater than or equal to -5
The domain and range of the function f(x)= x4 - 2x2-4 is all real numbers, and all real numbers greater than or equal to -5.
What is the domain and range of the function?The domain of a function is defined as the set of all the possible input values that are valid for the given function.
The range of a function is defined as the set of all the possible output values that are valid for the given function.
We are given that;
f(x)= x4 - 2x2-4
Now,
To find the range, we can consider the behavior of the function as x approaches positive or negative infinity. As x gets very large or very small, the x^4 term will dominate, and the function will become very large (positive for large positive x, negative for large negative x). So, we know that the range is not all real numbers.
We can also complete the square to rewrite the function in vertex form:
f(x) = (x^2 - 1)^2 - 5
From this form, we can see that the minimum value of f(x) is -5, which occurs when x = 0. Therefore, the range of the function is:
Range: all real numbers greater than or equal to -5
So, the answer will be Domain: all real numbers, Range: all real numbers greater than or equal to -5
