Answer:
-8
Step-by-step explanation:
Subtract 5 from both sides of the equation:
2+5=2−3
2+5−5=2−3−5
Simplify:
2=2−8
Subtract 2 from both sides of the equation:
2=2−8
2−2=2−8−2
Simplify:
0=−8
The solution to the algebraic expression has no solutions.
What is an algebraic expression?An algebraic expression comprises numbers, variables, and arithmetic operations with the aim of determining and finding a solution to the variables.
From the given expression, we have:
2x + 5 = 2x - 3
subtract 2x from both sides, we have:
2x -2x + 5 = 2x -2x - 3
5 = -3
Therefore, the solution algebraic equation has no solution since we don't have a variable to solve.

Edward hoppers oil painting nighthawks had a length of 60 inches and a width of 30 inches . A print of the original has a length of 2.5 inches. What is the width of the print in inches ?
Answer: 1.25 in.
Step-by-step explanation: 60:30 (L:W) if you simplify you will get 2:1, but simplify to 1:0.5 for convenience. you’ll multiply both by 2.5 (so you can get the length of 2.5) so now you have 2.5 : 1.25
Width of the print of original oil painting in inches = 1.25 inches
What is ratio?The ratio is defined as the comparison of two quantities of the same units that indicates how much of one quantity is present in the other quantity.
Given,
Length of the original painting = 60 inches
width of the original painting = 30 inches
Ratio of length to width = 60/30 = 2/1
Length of the print of original = 2.5 inches
Width of the print = ?
Ratio of length to width = 2.5/width of print = 2/1
⇒ width of print = 2.5/2
⇒ width of print = 1.25 inches
Hence, 1.25 inches is the width of the print of original painting.

4. What is the factored form of the expression 49x2 + 20?
A (7x + 215)(7x - 2/5)
B (7x + 2iV5) (7x - 2i75)
C (7xi + 275) (7xi - 215)
D (7xi +2175) (7xi - 2175
The factored form of the expression would be; (7x + 2√5) (7x - 2√5)
What are equivalent expressions?Those expressions that might look different but their simplified forms are the same expressions are called equivalent expressions.
To derive equivalent expressions of some expressions, we can either make it look more complex or simple. Usually, we simplify it.
We need to factor the expression form 49x² + 20
Therefore, 49 is a perfect square,
This expression could also be given as;
(7x)²- (2√5)²
Now, we know that:
a²- b² = (a + b) (a - b)
Now plug the values then we have:
(7x)²- (2√5)² = (7x + 2√5) (7x - 2√5)
Hence, the factored form of the expression would be; (7x + 2√5) (7x - 2√5)

Yoko is putting money into a savings account. She starts with $350 in the savings account, and each week she adds $40.
Let S represent the total amount of money in the savings account (in dollars), and let W represent the number of weeks Yoko has been adding money. Write an
equation relating S to W. Then use this equation to find the total amount of money in the savings account after 18 weeks.
Answer:
s=40w+350; s=$1,070
Step-by-step explanation:
Our equation looks like this:
s=40w+350
Next we plug in 18 for w, our number of weeks.
s=40(18)+350
Multiply the 40 and 18.
s=720+350
Add the 350 and 720.
s=1,070
Add a dollar sign to say that the amount is in dollars.
s=$1,070

The equation relating the total amount of money in the savings account, S and the number of weeks Yoko has been adding the money, W is given by S = 350 + 40W.
Total amount of money in the savings account after 18 weeks is
What is an Equation?An equation is a statement in mathematics which includes two algebraic expressions or numbers relating with an equal sign.
There are left hand side and right hand side for every equation and may or may not include variables.
S is the total amount of money in the savings account of Yoko.
W is the number of weeks Yoko has been adding money.
Initial money = 350
After 1 week total money = 350 + (1 × 40)
After 2 weeks, total money = 350 + (2 × 40)
It goes on like this until the last week.
So after W weeks total money = 350 + (W × 40)
Total amount of money in the savings account after W weeks, S = 350 + 40W.
After 18 weeks, S = 350 = (40 × 18) = $1070
Hence the equation relating W and S is, S = 350 + 40W.
Total amount of money after 18 weeks = $1070
