Answer:
The basic technique to isolate a variable is to “do something to both sides” of the equation, such as add, subtract, multiply, or divide both sides of the equation by the same number. By repeating this process, we can get the variable isolated on one side of the equation.

The cost of renting a car is $25 per day plus a one-time fee of $75.50 for insurance. How many days can the car be
rented if the total cost is to be no more than $525?
Answer:
the second choice 25x+75.50<525
75.50 + 25x < 525
The car can be rented for 17 days.
On the line you will have a lone pointing to the left with an open circle on 17.
75.50 + 25x < 525
25x < 525 - 75.50
25x < 449.50
x < 449.50/25
x < 17.98

Honeycrisp.
9 * 1.68 = 15.12
Fuji
7.4 * 1.15 = 8.51
17.28 + 15.12 + 8.51 = 40.91
Problem 16)
(area1) + (area2) + (area3) = (total area)
(1.25*4.38) + (1.36*2.15) + (1.14*3.55) = x
5.475 + 2.924 + 4.047 = x
12.446 = x
A pyramid is made above a cuboid with measure 90cm×50cm×225cm. If the height of the pyramid including cuboid is 240cm, find the total volume.
Answer: whatever do I care
Step-by-step explanation: I don’t care
The required volume of the pyramid is, 22500 cubic cm.
What is volume?Volume is referred to as the area occupied within an object's three-dimensional space.
Given that,
The length of cuboid = 90 cm
Width of cuboid = 50 cm
And height of cuboid = 225 cm
Let the height of the pyramid is x cm
Since the height of cuboid and pyramid = 240 cm
⇒ 225 + x = 240
⇒ x = 15 cm
Since the base of pyramid will be the same as the base of cuboid,
The volume of pyramid = 1/3 x base area x height
= 1/3 x 90 x 50 x 15
= 22500
The volume of the pyramid is 22500 cubic cm.

Hello I NEED help! Pls help in 10 min
what is 5/3 divided by 7
Answer:
Step-by-step Turn 7 into a fraction
3/5 ÷ 7/1
Use the recipricle and multiply
3/5 x 1/7
Multiply across
3/35
And that's it! :)
Answer:
5/21
Step-by-step explanation:
Here is a strategy I want you to remember: Keep, Change, Flip. What do I mean by that? Well...
Keep the first fraction. Change the division sign into a multiplication sign. Make the numerator of the second fraction become the denominator--and make the denominator of the second fraction become the numerator.
The denominator of any whole number is always 1. So, 7 equals to 7/1. Time to find the reciprocal of 7/1! What does reciprocal mean?
Reciprocal - Flip the fraction in terms of the numerator and denominator; Multiplicative Inverse
1/7 is the reciprocal of 7/1, for this mathematical problem. Makes sense, right?
Now, 5 times 1 equals 5 (that is the numerator). Secondly, 3 times 7 equals 21 (that is the denominator).
[tex]\frac{5}{3} * \frac{1}{7} = \frac{5}{21}[/tex]
The perimeter of the rectangle below is 54 units. What is the value of x?
Answer:
x has a value of 14.
Step-by-step explanation:
In addition to the information provided in the question, we are also told that the rectangle has a length x+1 and a width x-4. This is all we need to know.
To work this out, we simply need to plug those numbers into the equation for the perimeter of a rectangle. That would be p = 2l + 2w, where p is perimeter, l is length, and w is width.
We know that the resulting area (p) is equal to 54 units. We are also given variable values for the length and width. With that we can simply plug them into that equation and solve it for x:
[tex]p = 2l + 2w[/tex]
[tex]54 = 2(x + 1) + 2(x - 4)[/tex]
[tex]54 = 2x + 2 + 2x - 4[/tex]
[tex]54 = 4x - 2[/tex]
[tex]56 = 4x[/tex]
[tex]x = 56 / 4[/tex]
[tex]x = 14[/tex]

Step-by-step explanation:
If i'm wrong PLEASE correct me
The graph first is perfect negative correlation, graph second is the modest negative correlation.
What is correlation?It is defined as the relation between two variables which is a quantitative type and gives an idea about the direction of these two variables.
[tex]\rm r = \dfrac{n(\sum xy)-(\sum x)(\sum y)}{\sqrt{{[n\sum x^2- (\sum x)^2]}}\sqrt{[n\sum y^2- (\sum y)^2]}}[/tex]
As we know, the coefficient of correlation varies between -1 and +1.
If r = +1 (means the relation between the variable is strong and positive)
If r = -1 (means the relation between the variable is strong but negative)
As we can see in the graph, the line goes down represents the negative correlation and the line goes up represents the positive correlation.
So, we can say:
The first graph is perfect negative correlation.
The second graph is modest negative correlation.
The third graph is modest positive correlation.
The fourth graph is strong positive correlation.
The fifth graph is weak negative correlation.
Thus, the graph first is perfect negative correlation, graph second is the modest negative correlation.

Ill make you brainlist write in y=mx+b form
Answer:
y = [tex]\frac{2}{5}[/tex] x + 2
Step-by-step explanation:
Graph below.
Answer:
y = 2/5x + 2
Step-by-step explanation:
y = mx + b
First, we find out the slope. The slope is the change in y over the change in x.
The change in y is the second y-value subtracted from the first. The first y-value is 0 and the second is 2.
0 - 2 = -2
The change in x is the second x-value subtracted from the first. The first x-value is -5 and the second is 0.
-5 - 0 = -5
The slope is the change in y over the change in x.
-2/-5 = 2/5
y = 2/5x + b
b is the y-intercept, which is the value of y when x = 0.
When x = 0, y = 2 (0,2), so b = 2.
y = 2/5x + 2

.. pls help me....!!!!! Determine whether the point (-2,4) satisfy y<3x+5,y=3x+5 or y >3x+5..
Answer:
y < 3x + 5: No
y = 3x + 5: No
y > 3x + 5: Yes
Step-by-step explanation:
You can just put the value of x which is (-2) into each equation to see if the y value would be 4.
y < 3x + 5
y < 3(-2) + 5
y < -6 + 5
4 < -1 (This equation is wrong, so the point does not satisfy this equation)
y = 3x + 5
y = 3(-2) + 5
y = -6 + 5
4 = -1 (This equation is wrong, so the point does not satisfy this equation)
y > 3x + 5
y > 3(-2) + 5
y > -6 + 5
4 > -1 (This equation is correct, so the point does satisfy the equation)
What is the solution to the linear equation?

Answer:
∠6=116°
Step-by-step explanation:
Buckle up :)
We are given the values of ∠4 [tex](-2x+94)[/tex] and ∠8 [tex](-5x+139)[/tex].Vertical angles are congruent. Angle 4 and angle 1 are vertical angles, so angle 1 is also [tex]-2x+94[/tex].∠1 and ∠8 are alternate exterior angles. The transversal is the line that crosses over the parallel lines. When two angles are on opposite sides of the transversal, they are alternate angles. When the two angles are on the outside of the parallel lines, they are exterior angles. This makes them alternate-exterior angles.Alternate exterior angles are congruent. This means that ∠1≅∠8. Write an equation in order to solve for x:[tex]-2x+94=-5x+139[/tex]
Solve for x. Subtract 94 from both sides:
[tex]-2x+94-94=-5x+139-94\\\\-2x=-5x+45[/tex]
Add 5x to both sides:
[tex]-2x+5x=-5x+5x+45\\\\3x=45[/tex]
Divide both sides by 3:
[tex]\frac{3x}{3} =\frac{45}{3} \\\\x=15[/tex]
Insert the value of x into angle 4 because they are same-side interior angles. This is because they are on the same side of the transversal and within the parallel lines. Same-side interior angles are supplementary, so their value will add up to 180°. Therefore, in order to find angle 6, we need to first find the true value of angle 4:
[tex]x=15\\\\-2(15)+94\\\\-30+94\\\\64[/tex]
∠4 is 64°. Use ∠a+∠b=180 to find angle 6:
[tex]a+64=180[/tex]
a represents angle 6. Subtract 64 from both sides:
[tex]a+64-64=180-64\\\\a=116[/tex]
Angle 6 has a measure of 116°.
