No. 1 = x
No. 2 = 2x+7
No. 3 = x-12
Answer:
x+(2x+7)+(x-12) = 131
From there you solve to get the numbers:
34, 75 and 22
When x = 0 the value of the function is 2 so its either A or B.
When x = 1, y = 8 so substituting these values in A we get:-
8 = 2 * 8^1 = 16 so
its Not A. Try B:-
8 = 2 *4^1 = 8 which fits
Answer is choice B
Answer:
there you go
Step-by-step explanation:
The length of a train car is 50.6 feet. This is 5.8 feet less than 6 times the width. What is the width?
l = 50.6
We are also given:
6w - 5.8 = 50.6
Answer:
37.5%
Step-by-step explanation:
one day has 24 hours
100%->24
1%->0.24
9÷0.24 = 37.5%
Answer:
c
Step-by-step explanation:
Since both equations express y in terms of x we can equate the right sides
3x + 5 = - x + 3 ( add x to both sides )
4x + 5 = 3 ( subtract 5 from both sides )
4x = - 2 ( divide both sides by 4 )
x = - 0.5
substitute x = - 0.5 in either of the 2 equations
using y = - x + 3 then y = 0.5 + 3 = 3.5
solution is (- 0.5, 3.5 ) → c
