Answer:
D
Step-by-step explanation:
you have to multiply .79 to both a and 1.2. A is wrong because it's saying we need to multiply .79 to 1.2lb. which is the weight of oranges and the total cost of apples and oranges which is 6.27.
Answer:
X=4
Step-by-step explanation:
(3X/2) - (X/4) = 5
(6X-X)/4 = 5
(5X)/4 = 5
5X = 20
X = 4
Answer:
1. 0.5 = 5/10 ÷ 5 = 1/2
2. 0.7 = 7/10
3. 0.33 = 33/100 ÷ 33 = 1/3
4. 0.875 = (875/1000) ÷ 125 = 7/8
Start by dividing all terms by 4, to reduce this expression: |x+1| < 3.
Case 1: x+1 is already positive. The abs. val. operator does not change
anything. Then x+1<3, or x<2.
Case 2: (x+1) is negative. The abs. val. operator, in effect, puts a - sign in
front of (x+1): -(x+1)<3. Distributing the - sign: -x - 1 < 3. Adding 1 to both sides: -x < 4. We want to solve for positive x, so we mult. both sides of
-x<4 by -1 AND change the direction of the inequality symbol:
x > -4
Thus, the solution set is (-4,2): All real numbers between -4 and 2.
