Answer:
#1 s=-133/5
#3 a. b=-4
#3 b. x=23.45
#3 c. p=201
Step-by-step explanation:
#1 −5(s+30)=−17
Step 1: Simplify both sides of the equation.
−5(s+30)=−17
(−5)(s)+(−5)(30)=−17(Distribute)
−5s+-150=−17
−5s−150=−17
Step 2: Add 150 to both sides.
−5s−150+150=−17+150
−5s=133
Step 3: Divide both sides by -5.
−5s−5=133/−5
s=−133/5
#3 a.
Step 1: Multiply both sides by 2
Step 2: Simplify
b-6=-10
Step 3: Add 6 to both sides
b-6+6=-10+6
Step 4: Simplify
b=-4
#3 b. 0.4t(x-0.45t)=9.2
Step 1: Divide both sides by 0.4
Step 2: Simplify
x-0.45=23
Step 3: Add 0.45 to both sides
x-0.45+0.45=23+0.45
Step 4: Simplify
x=23.45
#3 -4(p-212)=44
Step 1: Divide both sides by -4
Step 2: Simplify (there is way more to this step than I am putting)
p-212=-11
Step 3: Add 212 to both sides
p-212+212=-11+212
Step 3: Simplify
p=201
Answer:
A.

pls give brainlest
It's the bottom one. Miko found the incorrect and checked her work using multipication incorrectly.
This is because the correct way to solve this would to use (5/1) * (3/5) = (15/5) then simplify it to 3/1 or simply 3.
Dividing fractions is simply flipping the second fraction and then multiplying across
Answer:
C
Step-by-step explanation:
Multiply the functions.
The triangle is not a right angle
AC = 22 - 8 - 5 = 9
AC² = AB² + BC²
81 = 64 + 25
81 isn't equal to 89, the triangle is not a right angle
