Joni should have multiplied by 1,000.
Step-by-step explanation:
Mass of the box = 67 decagrams
1 decagram = 1000 centigrams
So, 67 decagrams = 67 x 1000 centigrams
= 67000 centigrams
Joni should have multiplied by 1,000.
Answer:
Only option C is correct, i.e. The input, or independent variable, is years in operation.
Step-by-step explanation:
Given is the scatter plot of Years in Operation vs. Enrollment at Daycare Center.
The input is always independent variable and is plotted along x-axis.
The output is always dependent variable and is plotted along y-axis.
From the graph, it is clearly visible that:-
x-axis: Years in Operation.
y-axis: Enrollment at Daycare Center.
It means <u>"The input, or independent variable, is years in operation."</u>
Hence, only option C is correct, i.e. The input, or independent variable, is years in operation.
You do whatever you need to do to one side of the equation in order to have
only ' y ' left on that side, AND every time you do something to that side of
the equation, do exactly the same thing to the other side.
Here are three examples, out of the 9 answers you want handed to you:
<em>#16:</em> <u>3x + 5y = 7</u>
Subtract 3x from each side: 5y = -3x + 7
Divide each side by 5 : <em>y = -3/5 x + 7/5</em>
======================================
<em>#17: </em> <u>13 = 12x - 2y</u>
Add 2y to each side: 2y + 13 = 12x
Subtract 13 from each side: 2y = 12x - 13
Divide each side by 2 : <em> y = 6x - 13/2</em>
======================================
<em>#22:</em> <u>1/4 y + 3 = -5x</u>
Subtract 3 from each side: 1/4 y = -5x + 3
Multiply each side by 4 : <em>y = -20x + 12</em>
Answer:
3
Step-by-step explanation:
15-2x=3x
or,3x+2x=15
or,5x=15
or,x=15/5
Therefore, x=3.
Answer:
<em>x=9</em>
Step-by-step explanation:
If the triangles are congruent, then the angles B and E are also congruent (because they lie in the same place). Set an equation where B is equal to E:
∠
∠
Substitute values:
Solve for x. Divide both sides by 5:
So, when ΔABC≅ΔDEC, and ∠B=5x and ∠E=45°, the value of x is 9.
:Done
