Answer:
80 boxes of noodles
Step-by-step explanation:
10 cases x 8 boxes in each case = 80 boxes of noodles
10 x 8 = 80

Step-by-step explanation:
<u>Step 1: Define Inequality</u>
h - 8 > 4h + 5
<u>Step 2: Solve for </u><em><u>h</u></em>
- Subtract <em>h</em> on both sides: -8 > 3h + 5
- Subtract 5 on both sides: -13 > 3h
- Divide 3 on both sides: -13/3 > h
- Rewrite: h < -13/3
Here we see that any value <em>h</em> smaller than -13/3 would work as a solution to the equation.
Let:
x=ml of 30% alcohol solution
y=ml of 80% alcohol solution.
100 ml of 50% alcohol solution has 50 ml of alcohol and 50 ml of water.
50 % of 100 ml=(50/100)100 ml=50 ml
ml of alcohol in a 30% alcohol solution=0.3 (number of ml of 30% alcohol solution). In this case would be: 03x
ml of alcohol in a 80% alcohol solution=0.3 (number of ml of 30% alcohol solution). In this case would be: 0.8y
We can suggest this system of equations:
x+y=100
0.3x+0.8y=50
We can solve this system of equations by substitution method:
x+y=100 ⇒ y=100-x
0.3x+0.8(100-x)=50
0.3x+80-0.5x=50
0.3x-0.5x=50-80
-0.2x=-30
x=-30/(-0.2)
x=60
y=100-x
y=100-60
y=40
Answer: She should mix 60 ml of a 30% alcohol soluiton with 40 ml of 80% alcohol solution.
Answer:
<u>x = 18°</u>
Step-by-step explanation:
Step 1:
7x - 8° + 62° = 180° Supplementary ∠'s
Step 2:
7x + 54° = 180° Combine Like Terms
Step 3:
7x = 180° - 54° Subtract 54° on both sides
Step 4:
7x = 126° Combine Like Terms
Step 5:
x = 126° ÷ 7 Divide
Answer:
<u>x = 18°</u>

The length of one side is the square root of the area because a square has equal sides then the square root of 64 is 8
So each side is 8 inches and then adding all four sides gives a perimeter of 32 inches
