Answer:
Check the solution in both equations. The solution is ( − 1, 2). Solve the system by graphing: {− x + y = 12 x + y = 10 . Solve the system by graphing: {2x + y = 6 x + y = 1 . In all the systems of linear equations so far, the lines intersected and the solution was one point.

Answer: 104 men work for the company
Step-by-step explanation:
man = 4 x
woman = 7--------- you don't need these so i cross it out.
------------------------
total = 11 286
so you get 1144 - 11x
then divide 1144 by 11 and you get x = 104
Answer:
x=88° a=+3 b=4a-3
Step-by-step explanation:
as triangles ADE and BCE are congruent by sss axiom
so correponding angles are equal
i.e<AED = <BEC
and <DAE =90-60
=30°
so
62°+x+30°=180°
therefore x=88°
Answer:
1 1/4
Step-by-step explanation:
You are multiplying a fraction by a mixed number so you have to turn the mixed number into an improper fraction.
2 1/2 -- to do this you have to multiply the denominator by the whole number, then add the numerator.
2*2= 4 4+1=5
2 1/2 = 5/2
Then, you multiply normally
1/2 x 5/2 = 5/4
5/4= 1 1/4
So, you answer would be 1 1/4
Hope this helps!!

Answer:
7.4 in
Step-by-step explanation:
Surface area of a cube = 6s²
(where s is the side length)
Given:
Substituting the given value into the formula and solving for s:
⇒ 328.56 = 6s²
⇒ 328.56 ÷ 6 = 6s² ÷ 6
⇒ 54.76 = s²
⇒ s = √54.76
⇒ s = 7.4 in
