Simplify 5x + 3 -2x + 1
Answer:
3x+4
Step-by-step explanation:
When simplifying expressions, you need to combine like terms. 5x and -2x combined would equal 3x. Since the 2x was negative, you needed to subtract. Next, you combine 3 and 1, which should equal 4.
When putting the expression back together, make sure you leave it in the same order as received. This would mean you would put the coefficient with the variable first, and then put the whole number.
Make sure to take the signs into account. If it is negative, you subtract, and if it is positive, you add.

Answer:
9/16 inch
Step-by-step explanation:
A = 3/4 +1/16
B = 1/4
x = A - B
x = (3/4 +1/16) - (1/4) . . . an equation for the difference
x = (12/16 + 1/16) - 4/16 = (13 -4)/16
x = 9/16
The difference between A and B on the ruler is 9/16 inch.
Question A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River. Use h the formulat to find how many seconds it takes for the hammer to reach the river. Round your answer to the 4. nearest tenth of a second. s
Answer:15.8
Step-by-step explanation:
After 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.
What is a function?It is defined as a special type of relationship, and they have a predefined domain and range according to the function every value in the domain is related to exactly one value in the range.
It is given that:
A construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.
The equation is:
t = √h/4
Plug h = 4000 ft
t = √4000/4
After solving:
t = 15.81 seconds
Thus, after 15.81 seconds the hammer reaches the river if the construction worker drops a hammer while building the Grand Canyon skywalk 4,000 ft above the Colorado River.

A 10-gal aquarium is 4 in. higher than it is wide. Its length is 17 in., and its volume is 4284 in.^3. What are the height and width of the aquarium?
Answer:
[tex]W = 18[/tex] -- Width
[tex]H = 14[/tex] --- Height
Step-by-step explanation:
Given
[tex]V = 4284[/tex] -- Volume
[tex]L = 17[/tex] -- Length
[tex]H = ??[/tex] -- Height
[tex]W = 4 + H[/tex] -- Width
Required:
Find the height and the width
Volume is calculated as:
[tex]V = LWH[/tex]
This gives:
[tex]4284 = 17 * (4+H) * H[/tex]
[tex]4284 = 17 * (4H+H^2)[/tex]
Open bracket
[tex]4284 = 17 * 4H+17*H^2[/tex]
[tex]4284 = 68H+17H^2[/tex]
Divide through by 17
[tex]252 = 4H+H^2[/tex]
Write as a quadratic expression
[tex]H^2 + 4H - 252 = 0[/tex]
Expand
[tex]H^2 + 18H - 14H - 252 = 0[/tex]
Factorize:
[tex]H(H + 18) - 14(H + 18) = 0[/tex]
Factor out H + 18
[tex](H - 14)(H + 18) = 0[/tex]
[tex]H -14 = 0[/tex] or [tex]H + 18 = 0[/tex]
[tex]H = 14[/tex] or [tex]H = -18[/tex]
But Height can not be negative. So:
[tex]H = 14[/tex]
Recall that:
[tex]W = 4 + H[/tex]
[tex]W = 4 + 14[/tex]
[tex]W = 18[/tex]

[tex]18 + 9 \times 4 - 27 + 9[/tex]
Answer:
18Step-by-step explanation:
Given the expression 18+9*4-27+9
Using PEMDAS method
P is for parenthesis
E is for exponents
M is for multiplication
18+(9*4)-27+9
= 18+36-27+9
Next is Addition
= (18+36)-(27+9)
= 54-36
Then Subtraction
= 54-36
= 18
Hence the required value is 18

actor 14x+7y using the GCF.
Answer:
so to factor out you find the greatest common factor of 14 and 7
if you have 2x-2 then you can factor out the 2 and get 2(x-1)
7=7*1
14=2*7
the greatest common factor is 7
14x-7=7(2x-1)

becky spends 3/5 of her money she has left £60 left. how much money did she start with?
Answer: $150
Step-by-step explanation:
Becky spends 3/5 of her Money and is left with 2/5 of her money.
Hence 2 parts = $60
And 5 parts = $150
Becky has $150 at first.
Becky starts with $150.
What is Unitary Method?The unitary technique involves first determining the value of a single unit, followed by the value of the necessary number of units.
For example, Let's say Ram spends 36 Rs. for a dozen (12) bananas.
12 bananas will set you back 36 Rs. 1 banana costs 36 x 12 = 3 Rupees.
As a result, one banana costs three rupees. Let's say we need to calculate the price of 15 bananas.
This may be done as follows: 15 bananas cost 3 rupees each; 15 units cost 45 rupees.
Given:
Becky spends 3/5 of her money she has left £60 left.
let Becky earned be x.
so, x- 3/5x= 60
2x/5 = 60
x= 300/ 2
x=$150
Hence, Becky starts with $150.
