Answer:
option 4
Step-by-step explanation:
Using the rule of radicals
× 
= 
Given
(2 - 5
) 3
← distribute parenthesis by 3
= 6 - 15
= 6 - 15
= 6 - 15(
× 
)
= 6 - 15(2 )
= 6 - 30
67, 79, 81, 83, 83, 85, 87, 88, 89 then find the bumber in middle so answer is 83
Answer:
1.2
Step-by-step explanation:
78/65=
1.2
True
all rational numbers can be written in the form a/b where a and b are integers and b≠0
4 and 10 are integers and 10≠0 so it is a rational number
4m + 7a = 14.89
8m + 3a = 18.89
Multiply the first equation by 3 and the second equation by 7
12m + 21a = 44.67
56m + 21a = 132.23
Then subtract the equations and get:
44m=87.56
m=1.99
mangoes cost = $1.99<em>
</em>To find the price of apples, substitute with the mangoes on one equation
4(1.99) + 7a = 14.89
7.96 +7a = 14.89
7a = 6.93
a = 0.99
apples cost = $0.99
