Answer:
A. −19z − 77
Step-by-step explanation:
−9(z + 3) − 5(2z + 10)
The first step is to distribute
-9*z -9*3 -5*2z -5*10
-9z-27 -10z-50
-19z -77
Similar, they have the same angles but different sides.
Congruent is same sides, same angles.
The other 2 just ignore.
The answer is similar.
y < –12
Solution:
Step 1: Given inequality is y + 15 < 3.
To find the solution to the inequality.
Step 2: Subtract –15 on both sides to equal the expression.
⇒ y + 15 –15 < 3 –15
Step 2: Using addition identity property, any number adding with zero gives the number itself.
⇒ y + 0 < –12
⇒ y < –12
Hence the solution to the inequality is y < –12.
Answer:
Final Price = $385.60
You save = $96.40
Step-by-step explanation:
Discount = Original Price x Discount %/100
Discount = 482 × 20/100
Discount = 482 x 0.2
You save = $96.40
Final Price = Original Price - Discount
Final Price = 482 - 96.4
Final Price = $385.60
