Answer: a=1
Step-by-step explanation:
-8(a-4)+3a=2(4a+9)+1 given
-8a+32+3a=8a+18+1 distribute
+8a +8a
32+3a=16a+18+1 subtraction property of equality
-3a -3a
32=13a+18+1 addition property of equality
32=13a+19 add like terms
-19 -19
13=13a addition property of equality
÷13 ÷13
1=a multiplication property of equality
a=1 is the answer. Hope this helps!
Answer:
she need 1/2 ounce more.
Step-by-step explanation:
The morning dose = 3/4 ounce .
The noon dose = 1 /2 ounce .
The evening dose = 3/4 ounce .
Since the nurse has 1 ounce of medicine at noon ,

ounce.
So she need 1/2 ounce more.
Answer:
L = (6u + 5)m ; W = (2u-3)m
Step-by-step explanation:
Given;
Area of the rectangular vegetable garden, A = (12u² - 8u - 15)m²
Let the length of the rectangular vegetable garden = L
Let the width of the rectangular vegetable garden = W
A = L x W
Factorize the given area;
= 12u² - 8u - 15
= 12u² -18u + 10u - 15
= 6u(2u - 3) + 5(2u - 3)
= (6u + 5)(2u-3)
Thus, L = (6u + 5)m and W = (2u-3)m
Option B, is the right solution, although it was wrongly typed.
