Answer: Donate $71.40
Step-by-step explanation:
To calculate a percentage of an amount, we have to multiply that percentage by the amount and divide by 100.
Donate = $238 · 30 ÷ 100 = $7,140 ÷ 100 = $71.40
Answer : Donate $71.40

7y+9=7y-6
9 is not equal to -6
Let the unknown number be x
23-44x=199
23-199=44x
-176=44x
x=-4
Answer:
1) 8x
2) 12x - 3y
Step-by-step explanation:
1) Both of them have a like term, so you can subtract them across
2) 10x + 2x = 12x, have a like term so you can add them across and 3y is the outlier so that stays alone.
Hope this helps!
