A.2/7
B.7/50
C.3 1/2
D.1 3/5
→ The way I like to do these kind of math problems is below - I find it easier
A fraction usually means to divide, so I will start by dividing the numerator by the denominator of 7/10.
7/10 = 0.7, or, 70%
1/5 = 0.2, or, 20%
Now, we can go and divide each of our answers together.
0.7 ÷ 0.2 = 3.5 :D
Your final answer is 3.5

Answer:
Part a) The inequality is
The graph in the attached figure
Part b) 16 refrigerators and 7 pianos will not recharge the truck.
Step-by-step explanation:
Part a) Write and graph an inequality to show how many refrigerators and how many pianos the truck could carry
Let
x -----> the number of refrigerators in the truck
y -----> the number of pianos in the truck
we know that
The number of refrigerators in the truck multiplied by 200 lb plus the number of pianos in the truck multiplied by 525 lb must be less than or equal to 6,900 lb
so
The inequality that represent this situation is
using a graphing tool
The solution is the shaded area
Remember that the number of refrigerators or the number of pianos in the truck cannot be a negative number or a decimal number. The solution must be a whole numbers.
Part b) Will 16 refrigerators and 7 pianos overload the truck?
we know that
If a ordered pair is a solution of the inequality, then the ordered pair must satisfy the inequality
we have the ordered pair
(16,7)
Substitute x=16,y=7 in the inequality
-----> is true
The ordered pair satisfy the inequality
so
The ordered pair is a solution of the inequality
therefore
16 refrigerators and 7 pianos will not recharge the truck.
Answer:
Solve for y
Step-by-step explanation:
Subtract the x-term and divide by the coefficient of y.
9y = -2x +5
y = -2/9x +5/9
