Answer:
x=10
Step-by-step explanation:
-4 times x =-4x
-4 times 6 =-24
-4x-24=-64
add 24 to both sides
-4x=-40
divide -4 from both sides
x=10
Answer:
according to my calculation Lucita's estimate is too low.
Step-by-step explanation:
because if we divide 3.302 by -1.27 we get -2.6 but lucita wrote 0.026
so it means that she wrote is so low it has to be bigger
hope i helped
can i have brainliest plss
oh guys
Answer:
225 m²
Step-by-step explanation:
If W is the width of the rectangle, and L is the length, then:
60 = 2W + 2L
A = WL
Use the first equation to solve for one of the variables:
30 = W + L
L = 30 − W
Substitute into the second equation:
A = W (30 − W)
A = 30W − W²
This is a parabola, so we can find the vertex using the formula x = -b/(2a).
W = -30 / (2 × -1)
W = 15
Or, we can use calculus:
dA/dW = 30 − 2W
0 = 30 − 2W
W = 15
Solving for L:
L = 30 − W
L = 15
So the maximum area is:
A = WL
A = (15)(15)
A = 225
Answer:
45 minutes is 3/4 of an hour, so find 3/4 of 12.
Divide 12 by 4 to get 1/4 of 12. That is 3.
3/4 is 3 of those, so multiply it by 3 to get 9.
So, she will have biked 9 miles.
