Andre drank 1.2 liters out of 1.5 liters of water.
What is a expression? What is a mathematical equation?A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.A mathematical equation is used to equate two expressions.Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.We have Andre who drank 1.5 liters of water he brought. He drank 80% of his entire hike.
Assume that he drank [x] liters of water. Then -
x = 80% of 1.5 liters
x = (80/100) x 1.5
x = 8/10 x 1.5
x = 1.2 liters
Therefore, Andre drank 1.2 liters out of 1.5 liters of water.

The cost of 4 bananas is $2.36. What is the cost of each banana?
Mario's Work. StartFraction b Over 4 EndFraction = 2.36. A number line going from 9.41 to 9.49. A point is at 9.44.
Juan's Work. 4 b = 2.36. A number line going from 0.51 to 0.59. A point is at 0.59.
Daviana's Work. B minus 4 = 2.36. A number line going from 6.31 to 6.39. A point is at 6.36.
Answer:
B i think
Step-by-step explanation:
Juans work is correct because the equation to find cost of each banana is 4b=$2.36
What is Number system?A number system is defined as a system of writing to express numbers.
Given that the cost of 4 bananas is $2.36
We have to find the cost of each banana.
To find this we have to divide the cost by number of bananas
Divide two point three six by four
Banana is denoted by b
4b=$2.36 is the required equation
Cost of each banana =$2.36/4
=$0.59
Hence, Juans work is correct because the equation to find cost of each banana is 4b=$2.36

Find the x−and y−intercepts of −2x − 12y = 24.
Will give Brainliest!
Answer:
X= -12 -6y, Y= -2- x/6
Step-by-step explanation:
For x
-2x-12y=24
-2x/-2 -12y/-2. 24/-2. Divide all by -2
X+6y=-12 this is what you get after
-6y. -6y. Subtract from both sides
X=-12-6y this is what you get
Find y
-2x-12y=24
-2/-2. -12/-2. 24/-2
X -6y=-12
-x. -x
-6y=-12-x
-6y/-6. -12/-6. -x/-6
Y = -2 - x/6

Answer:
I can see how this is confusing, because of -2, but the slope is decreasing, so the question wouldn't say:
[tex]-3/5x - -2[/tex]
This happens to turn the -2 into a regular 2 with an addition (+) sign.
and since the graph has an input of 5 but an output of -3, the equation would be:
y = -3/5x + 2

The equation given was: (x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87.
Using this equation, write the equation with fewer terms.
Answer:
x = 13
Step-by-step explanation:
(x) + (x + 3) + (x - 2) + 3(x + 3) - 1 = 87
x + x + 3 + x - 2 + 3x + 9 - 1 = 87
6x + 9 = 87
6x = 87 - 9
6x = 78
x = 78/6
x = 13

-2(z+3)-z=-z-4(z+2)
solve for z quickly please! will give brainliest
Answer:
[tex] \sf z = - \dfrac{2}{3} [/tex]
Step-by-step explanation:
Solve for z:
[tex] \longrightarrow [/tex] -2(z + 3) = -z - 4(z + 2)
-4(z + 2) = -4z - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = -z -4z - 8
Grouping like terms, -z - 4z - 8 = (-z - 4z) - 8:
[tex] \longrightarrow [/tex] -2(z + 3) = (-z - 4z) - 8
-z - 4z = -5z:
[tex] \longrightarrow [/tex] -2 (z + 3) = -5z - 8
Expand out terms of the left hand side:
[tex] \longrightarrow [/tex] -2z - 6 = -5 z - 8
Add 5z to both sides:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = (5z - 5z) - 8
5z - 5z = 0:
[tex] \longrightarrow [/tex] (5z - 2z) - 6 = -8
5z - 2z = 3z:
[tex] \longrightarrow [/tex] 3z - 6 = -8
Add 6 to both sides:
[tex] \longrightarrow [/tex] 3z + (6 - 6) = 6 - 8
6 - 6 = 0:
[tex] \longrightarrow [/tex] 3z = 6 - 8
6 - 8 = -2:
[tex] \longrightarrow [/tex] 3z = -2
Divide both sides of 3z = -2 by 3:
[tex] \longrightarrow [/tex] [tex] \sf \dfrac{3}{3}z = - \dfrac{2}{3} [/tex]
[tex] \sf \dfrac{3}{3} = 1 :[/tex]
[tex] \longrightarrow [/tex] [tex] \sf z = - \dfrac{2}{3} [/tex]
