Start with (4/5)a. Mult. both numerator and denominator by 3. You'll get (12/15)a.
Thus, your (4/5)a = (12/15)a.
Answer:
Answer is -5°C.
Step-by-step explanation:
Initial temperature = 3°C
First decrease in temperature = 5°C
Second decrease in temperature = 3°C
Balloon ascend = 900 ft
Total change in temperature = 3-5-3 = -5
Thus final temperature = -5°C
Answer:
(a) f(7) = 23
(b) x = 13/3
Step-by-step explanation:
Step 1: Define
f(x) = 3x + 2
(a) f(7) is x = 7
(b) f(x) = 15
Step 2: Substitute and Evaluate
(a) f(7) = 3(7) + 2
f(7) = 21 + 2
f(7) = 23
(b) 15 = 3x + 2
13 = 3x
x = 13/3
Answer:
yes.
Step-by-step explanation:
Answer:
Two triangles are congruent if they have: exactly the same three sides and. exactly the same three angles
There are five ways to find if two triangles are congruent: SSS, SAS, ASA, AAS and HL.
SSS (side, side, side) ...
SAS (side, angle, side) ...
ASA (angle, side, angle) ...
AAS (angle, angle, side) ...
HL (hypotenuse, leg)
