Answer:
a. 11x + d
b. 15m + 10n
Step-by-step explanation:
a. 2(4c+5d) + 3(x-3d)
Break the brackets:
2*4c + 2*5d + 3*x - 3*3d
= 8x + 10d + 3x - 9d
Collect like termsL
= 8x + 3x + 10d - 9d
= 11x + 1d
b. 6(3m+n) - 4(m-n)
Break the brackets:
= 6*3m + 6*n - 3*m - 4*(-n)
= 18m + 6n - 3m - (-4n)
= 18m -3m + 6n + 4n
= 15m + 10n
Hope this helped :3
one of them is A but from how you showed me I dont really understand what you put
Answer:
x = 49/23
Step-by-step explanation:
23x=49
Divide each side by 23
23x/23 = 49/23
x = 49/23
Answer:
y = -3/2x + 2
Step-by-step explanation:
slope-line equation : y = mx + b
slope is -3/2
Let's find the y-intercept using (6, -7)
y = mx + b
-7 = -3/2(6) + b
-7 = -18/2 + b
-7 = -9 + b
+9 +9
-----------------------
2 = b
So, y = -3/2x + 2 is your equation.
