Answer:
Step-by-step explanation:
Let the number of the problems the team could solve before is x.
<u>Then we have:</u>
- x + 40% = 42
- 1.4x = 42
- x = 42/1.4
- x = 30
They were able to solve 30 problems before the new mathletes joined
Answer: 62.4$
Step-by-step explanation: 20% of 52 is 10.4
Answer:Give reasons for your answer that do not depend onsolving the equations. ... This can serve as a guide and check list for teacherswho are using the text for the ... Solution (a) If x = 2 and y = 5, then3x 4y = 3 2 4 (5) = 6 + 20 = 264x2+ 9x+ 7y = 4 ... oper-ation on the equation 3(x 1)+2x = 5+x2 2x?(a) 5x 3 = x2 2x 5(b) 4x + 3(x 1) .

Answer:
308.65 lb
Step-by-step explanation:
1 lb = 0.45359 kg
140 kg * (1 lb)/(0.45359 kg) = 308.65 lb
Answer:
-x aka -1
Step-by-step explanation:
x1 y1 x2 y2
9 -2 4 3
m= y2 - y1/x2 - x1
m = 3 + 2/4 - 9
(The "-" sign turned positive because it is negative times negative)
5/-5
Simplify: 5/-5 = -1 = -x
The slope of this line is -x
