Alright, so there's a rule to parallel lines that says that whatever the slope is of one of the lines, all of the lines parallel to it are going to have the same slope. The slope you have here is -5/1 or -5, therefore, your slope for every other line parallel to it will be the same.
Create a real world equality problem, then solve:
Example Problem:
Ana sells at least 220 shirts:
Ana Sold 85 shirts in the first 3 weeks of the month:
How many shirts must Ana sell in the last week of the month?
Solution:
Let S = the number of shirts Ana sells in the last week of the month.
Total Number of Shirts for the month must be greater than 220:
We Write: 85 + S ≥ 220
We Solve the inequality by Subtracting 85 from both sides: S ≥ 135
Therefore, Ana must sell 135 or more shirts in the last week to go on the school trip.
Solve: 85 + s ≥ 220 ========> S ≥ 135
Let's solve your inequality step-by-step.
85 + s ≥ 220
Step 1: Simplify both sides of the inequality.
s + 85 ≥ 220
Step 2: Subtract 85 from both sides.
s + 85 − 85 ≥ 220 − 85
s ≥ 135
Answer:
s ≥ 135
Check Problem:
85 + s ≥ 220 ========> S ≥ 135
We see that =====> 85 + 135 = 220
If Ana sells 135, or more shirts, The total number of shirts she sells that month will be 220 or more ========> Answer Checked
Hope that helps!!!!!!!!!!! : )
Answer:
The right side is bigger than the left side
Step-by-step explanation:
for the fraction on the left, -12/4 is -3 and plus 8 is 5. on the other side -5 - (-14) the negative on the -14 has another negative, so two negatives make a positive making the simpler equation -5 + 14 which equals 9.
Answer: 1
<u>Step-by-step explanation:</u>
a + b = 1
a³ + b³ = (a + b)(a² - ab + b²) <em>formula for a perfect cube</em>
a³ + b³ + 3ab = (a + b)(a² - ab + b²) + 3ab
↓
= 1 (a² - ab + b²) + 3ab
= a² - ab + b² + 3ab
= a² + 2ab + b² <em>this is a perfect square</em>
= (a + b)(a + b)
↓ ↓
= (1) (1)
= 1
Answer:
Step-by-step explanation:
The measure of exterior angle is equal to the sum of opposite interior angles.
So,
Exterior angle = 43+27
Exterior angle = 70°
