Answers
Step-by-step explanation:
Howdy, did you do a, b, and c by yourself? Because there are some slight issues, so I'll do my best to explain.
a. 3x+5x
We know that x=2, so we can substitute 2 in for x right now, or we can combine like terms.
3x and 5x both have the variable x so we can add them easily to get 8x. If you substitute in 2, you're just multiplying 8×2, which is 16.
b. 5z+4z+z
Again, since
we know that z=-3, we can substitute in now, or we can combine like terms first. 5z, 4z, and z all have the variable x, we addition is easy. 5+4+1=10, so you'll have 10z. Substitute in -3 for z, and you're just multiplying 10×-3=-30
c. 3x+6+5x
This is trickier since 6 doesn't have the variable x. So to combine like terms means to only add 3x and 5x. So the equation will turn out looming like 8x+6. now substitute in 2 for x and you get
8(2)+6
16+6
22
d. 8y+8-4y
Combine like terms
4y+8
substitute in 5 for y
4(5)+8
20+8
28
e. 5z-4z+z
combine like terms
z+z
2z
substitute -3 for z
2(-3)
-6
f. 3x+6+5x-2
combine like terms
(so that's 3x+5x and 6-2)
8x+4
substitute in 2 for x
8(2)+4
16+4
20
g. 8y+8-4y-3
combine like terms
8y-4y+8-3
4y+5
substitute in 5 for y
4(5)+5
20+5
25
h. 5z-4z+z-3z
combine like terms
-z
substitute in -3 for z
-(-3)
double negatives make a positive

Four times w is 16.
Answers
Answer:
w = 4
Step-by-step explanation:
4w=16
w = 16/4
w = 4
Step-by-step explanation:
The question is unclear. If the original question is telling you to make the word expression into an algebraic expression, the answer would be 4w = 16. On the other hand, if it was asking you to solve the given equation, the answer would be w = 4.

Andy bought total of 5 pairs of shoes and soxes. He bought some pairs of shoes and some pairs of soxes.
Set the variabloes as follows:
X = number of pairs of shoes
Y = number of pais of soxes
Which equation shows the total number of shoes and soxes he bought?
2x + 5 y =7
2X + 3 Y = 5
X + Y = 5
7Y - 2x = 5x
Answers
Answer:
The equation that shows the total number of shoes and soxes he bought is x+y=5.
Step-by-step explanation:
Given that statement says that Andy bought total of 5 pairs of shoes and soxes this means that the equation would indicate that the sum of the number of pairs of shoes plus the number of pairs of soxes is equal to 5, which can be expressed as:
x+y=5
The other answers are not right because the numbers of pairs of shoes and soxes are multiplied by another number and the statement indicates that the pairs of shoes and soxes is equal to 5.

Yes or no
Answers
Answer:
No, Yes, No
Step-by-step explanation:
3in by 4in by 5in will not make a triangle.
3in by 4in by 6in will make a triangle.
1m by 2m by 3m will not make a triangle.
The reason two of these triangles cannot be form is because the side lengths do not adhere to the triangle inequality theorem. This theorem states that the sum of the side lengths of any 2 sides of a triangle must exceed the length of the third side.

A seamstress charges a $5 fee per garment, plus $15 for each hour of work that the garment requires. The graph below shows the cost of having a single garment fixed by the seamstress, according to the number of hours of work that are needed.
Which linear function models the data?
A. c(t) = 5t
B. c(t) = 15t
C. c(t) = 5 + 15t
D. c(t) = 15 + 5t
Answers
Answer:
C. c(t) = 5 + 15t
Step-by-step explanation:
Well because the initial fee is $5, the answer must have the value of 5 without a variable next to it because this is the y-intercept.
(Only the slope will have the t next to it.)
Because $15 is charged EACH HOUR this would be the slope because there is a constant increase
Therefore c(t) = 5 + 15t
Answer:
C. c(t) = 5 + 15t
Step-by-step explanation:
She charges $15 per hour, so each hour (represented by "t") she earns 15 dollars. She also charges a $5 fee per germent. So she would get $5 plus 15 times however many hours she worked. So your answer would be c(t) = 5 + 15t.

of 36 and 48 using
prime factors
Answers
Answer:
Step-by-step explanation:
Least common multiple can be found by multiplying the highest exponent prime factors of 36 and 48. First we will calculate the prime factors of 36 and 48.
Prime Factorization of 36
Prime factors of 36 are 2, 3. Prime factorization of 36 in exponential form is:
