Answer:
(1, 1 )
Step-by-step explanation:
Given the 2 equations
2x + 3y = 5 → (1)
7x - 5y = 2 → (2)
Multiplying (1) by 5 and (2) by 3 and adding will eliminate the y- term
10x + 15y = 25 → (3)
21x - 15y = 6 → (4)
Add (3) and (4) term by term to eliminate y
31x = 31 ( divide both sides by 31 )
x = 1
Substitute x = 1 into either of the 2 equations and evaluate for y
Substituting into (1)
2(1) + 3y = 5
2 + 3y = 5 ( subtract 2 from both sides )
3y = 3 ( divide both sides by 3 )
y = 1
Solution is (1, 1 )

Just answered it
Answer:
3.75
Step-by-step explanation:
g(x)=60(1-0.5)^x, g(4)
g(4)=60(1-0.5)^4
g(4)=60(.5)^4
g(4)=60(0.0625)
g(4)=3.75
The answer is D: 16,800 because you multiply the principal ($6,000), rate (7%), and time (4 years) to get the interest
Answer:
C
d=(0.6)(30)
Step-by-step explanation:
Let the distance run in 30 minutes be d
Given the zebra can run 0.6 miles in one minute
That’s
0.6mile = 1 minute
How far can the zebra run in 30 minutes
That’s
d miles = 30 minutes
Therefore, we now have
0.6mile = 1 minute
d mile = 30 minutes
Cross multiply
d x 1 = 0.6 x 30
d = 0.6 x 30
Or
d = (0.6)(30)
