Answer:
Value x = 8 make the equation true .
Step-by-step explanation:
Given : 3x = 24.
To find : Which value of x from the set {5, 6, 7, 8} makes this equation true?
Solution : We have given 3x = 24.
The equations are true when the Left hand side and right hand side of the equation are equal.
Then,
For x = 8 .
3 ( 8) = 24
24 = 24 .
Hence,
Left hand side = Right hand side.
Therefore, Value x = 8 make the equation true .
I believe 2 7/15 is the answer:)
A) x * y = 12
B) x + y = -7
A) x = 12 / y
Substitute this into B
B) 12/y + y = -7
multiplying both sides by "y"
12 + y^2 = -7y
y^2 + 7y + 12 = 0
y = -4
and from equation B we calculate x as -3
Answer:
The last one, −2.1−(5.9+3.7)
Step-by-step explanation:
−2.1+(−5.9)+(−3.7) = -2.1-5.9-3.7 = -11.7
the only expression that will come out as -11.7 is the last one
The dimensions would have to be 20 x 5 as the model holds the same amount for each side, and because 5 is larger than 4 its used as the models stand.
Hope it helps! :)
