To answer the equation first, let x be the number of pens. With this representation, the number of pencils she bought would be x - 4. The total amount she would have to spent for all the items is,
T = 6.70x + 3.5(x - 4)
Answer:
It is B, reason being because the triangle is clearly equilateral meaning the triangle is practically a perfect triangle! Hope this helped! :D
Complimentary means they equal 180 so if one is 5 more then 4 times the other one is m<1= x and m<2= 4x+5°. Then solve for x. So! x+4x+5= 180. (solve to get) x=35. SO IN CONCLUSION::: <1= 35 (x) and <2= 145 (4x+5) using substitution after solving to find x.
Answer:
its answer is the same as the top, s³+12
