How many solutions exist for the given equation?
0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)
zero
one
two
infinitely many
Answer:
its b lol
Step-by-step explanation:
jus got it right
There is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.
What is a linear equation?A linear equation is an equation that has the variable of the highest power of 1. The standard form of a linear equation is of the form Ax + B = 0.
We have a linear equation in one-variable:
0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20)
0.75(x + 40) = 0.7(x + 20)
75(x + 40) = 70(x + 20)
75x = 70x - 1600
x = -370
Hence, there is only one solution which is x = -370 to the given equation 0.75(x + 40) = 0.35(x + 20) + 0.35(x + 20) option B is correct.

-16x = - 352 step equations
Answer:
x = 22Step-by-step explanation:
-16x = - 352 divide by -16 both sides
x = -352/-16
x = 22
Answer:−16x=−352
Divide both sides by −16.
x= −352/−16
Divide −352 by −16 to get 22.
x=22

We have to find the lcm (lowest common multiple) of the number.
We do that by taking their multiples. Watch down below
3 x 1 = 3 4 x 1 = 4
3 x 2 = 6 4 x 2 = 8
3 x 3 = 9 4 x 3 = 12
3 x 4 = 12
See how they both have a 12 as their first lcm.
So the 12th customer gets both items.

What is the slope of a line perpendicular to the line whose equation is
12x + 2y = –12. Fully reduce your answer.
The slope of the line is - 6. Then the slope of the perpendicular line will be 1/6.
What is the equation of a perpendicular line?If the slope of the line is m, then the slope of the perpendicular line will be negative 1/m. The equation is in the form of slope-intercept form. Then the equation of the line is given as
y = mx + c
Where m is the slope of the line and c is the y-intercept of the line.
The equation of the line is given as,
12x + 2y = - 12
Convert the equation in the slope-intercept form, then the equation will be given as,
Separate the variable y, then the equation is given as,
6x + y = - 12
y = -6x - 12
The slope of the line is - 6. Then the slope of the perpendicular line will be 1/6.

A shop sells matching hats and scarves.The scarves cost 1.5 times as much as the hats.Write two patterns that could represent the cost of 1234 and 5 hats and scarves.List the first 5terms of each pattern.Then explain how to find the cost of 6hats and scarves,using the patterns you wrote u
Answer:
Kindly check explanation
Step-by-step explanation:
Given that :
Let Cost of hats = h
Cost of scarves = 1.5h
Hence if hats cost $h, then the cost of scarves will be; (1.5 * h)
Using tables :
If the cost of an hat = $2
Hence,
N _____cost of hat(h) ____cost of scarve
1_______2*1 = 2 _________1.5(2) = 3
2______2 *2 = 4 _________1.5(4) = 6
3______2*3 = 6 _________1.5(6) = 9
4 ______ 2*4 = 8 ________1.5(8) = 12
5 ______2 *5=10 ________1.5(10) = 15
Cost of 6 hats and scarve:
Cost of hat:
2 * 6 = $12
1.5h = 1.5(12) = $18

therefore multiplying 12 by 10 gives us 120
Answer:
y=120 when x=12
Step-by-step explanation:
From the pattern I noticed that y is pretty much 10 times the value of x. So when x equals 12, y will equal 120.
