x + (x + 3) +
= 75
so you will add up all of the x 's but NOT the x^2
2x + 3 +
= 75
Rearrange to put the x^2 in front of 2x
+ 2x + 3 = 75
subtract the 75 from both sides
+ 2x - 72 = 0
Answer:
-2.5x+y=11.5
Step-by-step explanation:
y-4=2.5(x+3)
distribute the 2.5 into the parenthesis
y-4=2.5x+7.5
add 4 to both sides
y=2.5x+11.5
now that it's in slope intercept form it will be easier to get into standard form
now subtract 2.5x from both sides
-2.5x+y=11.5
hope this helps you
0.10c + 0.12b = 2.18
c = 4b + 1
0.10(4b + 1) + 0.12b = 2.18
0.40b + 0.10 + 0.12b = 2.18
0.40b + 0.12b = 2.18 - 0.10
0.52b = 2.08
b = 2.08 / 0.52
b = 4 <==== she had 4 bottles
c = 4b + 1
c = 4(4) + 1
c = 16 + 1
c = 17 <=== she had 17 cans
I’m not sure but it has to be half Gabriel’s age
