Answer:
Step-by-step explanation:
2 easy ways:
1. Divide 7 by 3 then multiply by 2
7/3= seven thirds or 2.333
Now multiply by two to get 14 thirds
or 4.666
2. Multiply 7 by 2/3, or 0.666
This way is a lot easier with a
calculator
The weight of the box is 14/3’s or 4.666

Answer:
Using the elimination method to solve for x and y; ANSWER: y=2 & x=-20
Step-by-step explanation:
1) It helps to visualize the equation if you put the second equation underneath the first like regular adding.
(2x+10y= -20)
+ (-x+4y= 28)
____________
?
2) You always want to cancel out one value (x or y) to start the process.
In this case, if I can get a -2x to cancel out 2x (neg. and positive cancel), that would cancel out the x's in the two equation. To do that, I would multiply by 2 to the second equation and add like you would normally (like terms with like terms, x with x and y with y)
2x+10=-20 2(-x+4y=28) ---> 2x+10y= -20 <u><em>plus</em></u> -2x+8y=56 --->18y=36 (this is the final simplified outcome)
3) find y so y =36/18 so y =2
4) Plug y=2 back into one of the original equation and solve for x
2x+10(2)= -20 ---> x=-20
Answer:
B) Yes, ΔMNO ≅ ΔPON by SAS
Step-by-step explanation:
The Side Angle Side (SAS) postulate states that if two sides and the included angle of one triangle are congruent to two sides and the included angle of another triangle, then these two triangles are congruent.
In this case, side MO is congruent to side NP and side NO is shared by both triangles. The included angle in ΔMNO is ∠O and in ΔPON is ∠N, and they are congruent.
