Answer:
81
Step-by-step explanation:
just do it step by step adding them together.
Answer:
Option C
Step-by-step explanation:
By the property of a rectangle,
"All interior angles of a rectangle measure 90°"
Therefore, m∠ABC = 90°
By applying cosine rule in the right triangle ABC,
cos(∠CAB) = 
cos(25°) = 
AC = 
AC = 
AC = 19.86
Therefore, Option C will be the answer.
Answer:
; line D in the options.
Step-by-step explanation:
The set of equations has no solutions if the two lines are parallel. A quick way to create a parallel line is to solve for y, put it in slope-intercept form. Else, as long as the cofficient of x and y are in the same ratio (in this case 1:1), the two lines are parallel, you just have to be careful not to pick the same line again!
The condition
makes sure you are still getting lines (else you would get rid of both x and y); the condition
makes sure you're not picking line A again, just written in a different form.
Now that we have the options:
A and C have a different ratio for the coefficient of x and y (2:1 and 1:2) so are not good.
Choice B is just a more complicated way to write the same line, you can see by dividing both sides by 2 and get back x+y=2.
Line D is correct.
Answer:
2.35y = 4.70
4 = 10w
55x = 111
Step-by-step explanation:
Hi, the division property of equality states that if we divide both sides of an equation by a non-zero number, the equality remains. (Both sides remain equal).
So, the equations that we have to use the division property of equality to solve are:
Dividing both sides by 2.35:
2.35y /2.35= 4.70/2.35
y= 2
4/10=10w/10
0.4=w
55x/55 =111/55
x = 111/55
