The given solution x=4 is false for 2x-5 = 13.
What is Equation?Equations are mathematical statements with two algebraic expressions flanking the equals (=) sign on either side.
It demonstrates the equality of the relationship between the expressions printed on the left and right sides. LHS = RHS is a common mathematical formula.
Coefficients, variables, operators, constants, terms, expressions, and the equal to sign are some of the components of an equation. The "=" sign and terms on both sides must always be present when writing an equation.
Given:
2x−5 = 13
Now, for x=4
2(4)- 5
= 8-5
= 3
As, the LHS part of equation is not equal to RHS part.
Hence, the given x=4 is false for 2x-5 = 13

The cost of renting a car is $ 30 /week plus $ 0.25 /mi travelled during that week. An equation to represent the cost would be y = 30 + 0.25 x , where x is the number of miles. What is your cost if you travel 35 miles? $ If you were charged $ 42.50 , how many miles did you travel? miles Get Help: VIDEO LicensePoints possible: 1
Answer:
Amount charged for 35 miles is $ 38.75
If amount charged is $ 42.50 then distance travelled is 50 miles
Step-by-step explanation:
Equation that represents the cost is [tex]y=30+0.25x[/tex]
Here,
x denotes the number of miles
$ 30 is the amount of rent per week
$ 0.25 is amount charged for 1 mi
To find cost if distance travelled is 35 miles, put [tex]x=35[/tex] in [tex]y=30+0.25x[/tex]
Cost (y) = [tex]30+0.25(35)=\$38.75[/tex]
So,
Amount charged for 35 miles is $ 38.75
To find number of miles for which amount charged is $ 42.50, put [tex]y=42.50[/tex] in [tex]y=30+0.25x[/tex]
[tex]42.50=30+0.25x\\42.50-30=0.25x\\12.5=0.25x\\x=\frac{12.5}{0.25} \\x=50[/tex]
So,
if amount charged is $ 42.50 then distance travelled is 50 miles.
Explain how you would graph the line containing a slope of-1/5 that goes through the point (1,-4)
Answer:
y= -1/5x + 1/5
Step-by-step explanation:
y- y1 = m(x - x1)
Slope m=-1/5
(1, -4)
1 = y1
-4 = x1
y- 1 = -1/5(x-(-4))
y-1 = -1/5(x+4)
y-1= -1/5(x)+ -1/5(4)
y-1 = -1/5x + -4/5
add one to both sides
y= -1/5x + -4/5 + 1
y = -1/5x + 1/5

Crystal baked 54 muffins for her family and friends. Her friends take 1/6 of the muffins. How many muffins does she have left? Of the muffins that she has left, her family took 2/5 of them. How many muffins did her family take? After her friends and family have taken their muffins, Crystal eats 1/3 of what is left. How many muffins did Crystal eat?
Answer:
she has 45 muffins left
her family took 18 muffins
crystal ate 9 muffins
Step-by-step explanation:
54 × 1/6 = 9
54 - 9 = 45
45 x 2/5 = 18
45 - 18 = 27
27 x 1/3 = 9
