If 2a + 2 = 8, then a is equal to 3 using linear equation.
What is linear equation?A linear equation most effective has one or two variables. No variable in a linear equation is raised to a strength greater than 1 or used because the denominator of a fraction. whilst you discover pairs of values that make a linear equation authentic and plot the ones pairs on a coordinate grid, all of the factors lie at the same line.
The definition of a linear equation is an algebraic equation wherein every term has an exponent of 1 and the graphing of the equation outcomes in a immediately line.
An example of linear equation is y=mx + b.
Nonlinear equations are equations that appear as curved lines while you graph them. If the differences among the outputs of the equation are inconsistent when you operate unknown variables, then the equation is nonlinear. Nonlinear equations can take many shapes, from simple curves to elaborate
An equation is said to be linear equation in variables if it is written within the shape of ax + by way of + c=0, wherein a, b & c are real numbers and the coefficients of x and y.
explanation:
2a + 2 = 8
2a = 8 -2
a = 6/2
a = 3
Hence, the value of a is 3.

Marcel buys 5-star apples for PhP5.00 each and 3 guyabanos for PhP32.50 each.
She gives the cashier a PhP200.00 bill. Write an expression for the total cost of the fruits
she buys and an equation for the amount of change the cashier should give her.
Il Questions to Ponder
1. How to use variables to represent the price of each fruit?
2. How to write an expression for the total cost of the fruits she bought and an
equation for the amount of change the cashier should give her?
Answer: See explanation
Step-by-step explanation:
Let the price of apples be represented by a
Let the price of guyabanos be represented by g.
Since Marcel buys 5-star apples for PhP5.00 each and 3 guyabanos for PhP32.50 each. This will be:
C = 5a + 3g
where
a = PhP5.00
g = PhP32.50
c = Total cost
Therefore, an expression for the total cost of the fruits she buys will be:
C = 5a + 3g
C = 5(5.00) + 3(32.50)
The equation for the amount of change the cashier should give her if she gives the cashier PhP200.00 will be:
= 200.00 - 5(5.00) + 3(32.50)
= 200.00 - (25.00 + 97.50)
= 200.00 - 122.50
= Php77.50

1. 60
2. 0
3. 30
4. -60
5. -20
Answer:
-60
Step-by-step explanation:
-3(x + 10) + 2x = 30 becomes -3x - 30 + 2x = 30 after having performed the multiplication. Combining like terms, we get -x = 60, so that x must be -60 (Answer 4)

105 + 105= 210
210 + 105= 315
315+ 105= 420
420 + 105 = 525
The answer is 525
There is another way to do it ok soo if we multiply 100 x 5 = 500

Answer:
500 + (40x)
Step-by-step explanation:
she already has 500 in her bank account and there are multiple weeks. 40 dollars per week would be 40x since we don’t know how many weeks. then put it in an equation!
Answer:500 + 40w = m
Step-by-step explanation:
500 is the amount you had already then you add 40 per a week so you times that by w depending on the weeks and m is money overall.

Determine the radius of a cylinder with the curved area 24cm squared and height 2.0cm
Answer:
the radius of the cylinder is 1.91 cm
Step-by-step explanation:
Given;
curved area of the cylinder, A = 24 cm²
height of the cylinder, h = 2.0 cm
The curved surface area of a cylinder is given as follows;
Curved surface area = 2πrh
where;
r is the radius of the cylinder
24 = 2πrh
r = 24 / (2πh)
r = 24 / (2π x 2)
r = 24 / (4π)
r = 1.91 cm
Therefore, the radius of the cylinder is 1.91 cm
