X is one angle
X+78 is the second angle
Add them together
2x+78=90
Subtract 78 from both sides
2x=12
X=6
One angle is 6 the other angle is 84
∠1 and ∠2 are supplementary // given∠3 and ∠4 are supplementary // given∠1 ≅ ∠3 // given m∠1 + m∠2 = 180° // definition of supplementary anglesm∠3 + m∠4 = 180° // definition of supplementary angles m∠1 + m∠2 = m∠3 + m∠4 // transitive property of equality m∠1 = m∠3 // definition of congruent angles m∠1 + m∠2 = m∠1 + m∠4 // substitution property of equality (replaced m∠3 with m∠1) m∠2 = m∠4 // subtraction property of equality (subtracted m∠1 from both sides) ∠2 ≅ ∠4 // definition of congruent angles
Answer:
$400
Step-by-step explanation:
Let 'p' represent the original price, the 'p-0.3p' represents the sale price:
280 = p - 0.3p
.
Solving for 'p' we have p=400.
The original price of the television was $400
Answer:
See example below.
Step-by-step explanation:
To scale down by a factor of 1/10, multiply the side length or distance by 1/10.
Example:
If the distance was 5 then 5*1/10 = 5/10 = 1/2 is the scaled down version.
Answer:
look at step by step
Step-by-step explanation:
A) That is the number of bacteria that originally started in the culture
B) That is the rate at which the bacteria will reproduce
C) 1000 represents the number of bacteria at the beginning of the second culture.
The first study started with more bacteria, and will grow faster because of this
