A+b=32
4a+7b=200
a = 15
b = 20
There are 15 four pointers and 20 seven pointers. You can plug in the numbers to check.
I believe this is correct. If not i am extremely sorry.
Have a wonderful day :)
Answer:
Answer: (2a - 5 + b)5
Answer: 10 x (a - 2.5 + 0.5b)
Answer: (-2a + 5 - b) ⋅ (-5)
Question 13-18 & 22-27 will all be answered the same way, so i will walk you through question 13: (6,4) y=3x-2
(x,y)=(6,4)
now that we know the first number in the parenthesis is the x value and the second number in the parenthesis is the y value we can plug it into the equation. (x=6,y=4)
4=3x-2 (add two to each side)
4+2=3x
6=3x (divide 3 from each side)
x=2
---------------
y=3(6)-2
y=18-2
y=16
-------------------
answer: (2,16)
