Answer:
<h2>
30 cm²</h2>
Step-by-step explanation:
- Area of triangle = 1/2 (base × height)
1/2(12*5)=
1/2*60=
30 cm²
2|x-2|-12=0
Rearrange variables to the left side of the question
2|x-2|=12
Dividing both sides of the equation by the coefficent of variables
|x-2|=12/2
Reduce the fraction
|x-2|=6
Split into two variables
x-2=6 or x-2=-6
Rearrange variables to the left side of the equation
x=6+2
x=8 or x=-4
when x=8
LHS=2|8-2|-12=0
RHS=0
LHS=RHS
x=8 is valid
A variable in mathematics is an alphabet or phrase that stands in for an unknowable amount, unknowable value, or unknowable number. Particularly in the case of algebraic expressions or algebra, the variables are utilised. As an illustration, the linear equation x+9=4 has the variables x and 9 as constants.
A variable is a letter or symbol that stands in for any individual integer in a group of two or more. A constant is a letter or symbol that stands for a single particular number, whether it is known or unknown.
In mathematics, variables serve as stand-ins for unknowable numbers. Variables can be utilized in formulae, equations, and expressions in mathematics. When it's necessary to find the optimum solution, variables are frequently employed.

Y=4
How?
When they say directly you should multiply the x and y together. You would get -24, now using that number divide -24 by the new x(-6) you would get 4.
Answer: $570
Step-by-step explanation:
She worked 5 hours more than 40. Thus, for her extra hours she made 18*5, or $90. For her other 40, she made 40*12, or $480. Thus, she made 480+90 dollars, or $570.

Let the price of coffee be x and the price of latte be y.
Thus forming the equations given the information we shall have:
2x+y=10.50
y=10.50-2x.......i
3x+2y=17......ii
plugging i in ii we get:
3x+2(10.50-2x)=17
3x+21-4x=17
3x-4x=17-21
-x=-4
thus
x=4
Thus the cost of coffee is $4
thus the cost of latte will be:
y=10.50-2(4)
y=10.50-8
y=2.5
Price of latte is $2.5
