1. (5+23)+65 = (5+65)+23 = 70+23 = 93 (D)
2. -(4x-7) = -4X+7 (C)
3. 2(6X+9) = 12X+18 (B)
4. 5(X-3) = 35
X-3 = 35/5
X-3 = 7
SO X= 7+3 = 10
THEN NO
9 IS NOT A SOLUTION
Answer:
Each egg is $5 so 4 dozen(48) is $240
Step-by-step explanation:
the way to do this is 75/15= 5
and then you multiply 12 x 4 to get 48 eggs
and then multiply 48 x 5 to get $240
Answer:
6 weeks
Step-by-step explanation:
18x 6 = 108
116+108=223
Guessing that the 3 was suppose to be an exponent.
The answer written in standard form is :
4x^3 + 10x - 4
This is called a cubic trinomial.
All angles in a triangle add to 180
so
w+2w+69=180
3w+69=180
3w=111
w=37
